Late Summer's Larger Blooms

Now that summer is nearly over I thought I would do a run down of some of the showier native plants that I have around the property.  Most of these are found naturally in Maryland.  A few are true wild flowers that have arrived on their own, though most of these have been introduced to this site.

The most common wildflower to this area is Wingstem, Verbesina alternifolia.  It is tall (4-6 ft) in full sun, though shorter in shadier locations.  The bright yellow compound blooms have been evident since the beginning of August.  In this area it is currently the dominant roadside wild flower.

This wildflower was just fading out at the beginning of October last year and I could not figure out what it was.  The northern edge of it range is in New York state, so it would be uncommon in the Boston area.  The form of the plant is similar to Sneezeweed (Helenium) but the shape and quantity of the petals are different.  Sneezeweed has wedge-shaped petals tightly arrayed around the center disk.

The arrows point out the winglike appendages
on the stems, hence the common name.  

Before the Wingstem was in full bloom, Common Evening Primrose, Oenothera biennis, was dominating the roadsides.  This is a true biennial.  It spends the first year as a low growing leafy rosette.  The second year the flower stalk shoots up to 6 ft or more with spikes of yellow blooms.  Each flower opens in the evening and only lasts a day (maybe a little longer if it is cloudy).  I have a bunch of these growing around our patio, while the flowers are nice and bright, they have unsightly lower stems.  For this reason I would banish them to the background.  The biennial lifecycle is well adapted to highly disturbed environments.  The seeds need an open sunny area to germinate and for the low-growing rosette to get plenty of sunlight.  So this is a good plant for open roadsides that get cleared once or twice a year.  But not so good for an area with an established dense undergrowth.

Evening Primrose gets way too leggy
to use near the front of a border.

I noticed that the Japanese beetles were eating a lot of the Evening Primrose leaves.  I collected quite a few in my soapy water jug (aka, Jug of Death).  Could these plants be used as a magnet to draw the beetles away from more desirable garden crops?




This next group of wildflowers are native to Maryland, although I am pretty sure they are not indigenous to our little valley.  New York Ironweed, Veronia noveboracensis, is scattered around our house, but I have not seen it growing in the woods or along the roadside.  The deep purple flowers are long lasting and provide a wonderful contrast to all of the yellow flowers that are dominating the gardens at this time.  In protected areas these wildflowers can get quite tall, more than 6 ft.  In open areas the deer have pruned them back to 2-3 ft tall, but they have still managed to bloom.  At this smaller size they actually fit in better to the garden scale.

This Ironweed was not eaten back by deer and
grew to about 5 ft in partial shade.

Speaking of yellow flowers, there are lot of Yellow Cone Flowers, Rudbeckia fulgida, growing in the neighborhood.  Probably most are the 'Goldstrum' cultivar.  They all grow to the same height and bloom at the same time, making a definite statement in the garden.  As a advocate for native annuals and biennials (i.e. short lived, freely seeding plants) I have been using more of the Black-eyed Susans, Rudbeckia hirta.  These have a more relaxed habit and a longer blooming cycle than the more common cone flower cultivars.  (note some variation to the flower shape).

These Black-eyed Susans were raised from seed this year.
They are not all identical, note the double-side blossom on the right.

In the shadier areas of the garden I have added them more demure Brown-eyed Susan, R. triloba, and the shade tolerant Elm-leaved Goldenrod, Solidago ulmifolia.  This is the first year that this goldenrod has bloomed.  It is an early bloomer and really brightened up the shady area, but the color only lasted a couple of weeks.  I just planted in some Bluestemmed Goldenrod, S. caesia, to beef up the appearance.  I just read that these two species can hybridize - so I guess that the bloom times will be similar.

This plant was eaten back once.  If unpruned
it would reach 304 ft tall.

This is an early blooming species of Goldenrod
that does well in shadier locations.

I found that I had problems with the deer and possibly rabbits eating back both the Rudbekia and Solidago.  I gave these plants a little assistance with some hot pepper spray (cayenne pepper) and some scent-based deterrents like 'Repels-All.'  I need to get on a regular application schedule with products because waiting for the plants to be eaten is usually too late.  I have also gone too far with over application on new plants resulting in killing much of the tender foliage with the liquid sprays.  For these plants I am favoring the pelleted products.

Partridge pea, Chamaecrista fasciculata, is a true native annual that I planted this spring.  I had better results with plants started indoors than outdoors, but much of this was due to grazing by unwelcome animals.  After a little hot pepper spray I was rewarded with stems full of loose yellow blooms.  These open blossoms were visited primarily by larger bees.  These peas need a specific symbiotic bacterium to assist with nitrogen fixation.  This was supplied with the seeds I bought.

The leaves of the Partridge Pea will fold up when it is dark or particularly windy.

In the vegetable garden I'm growing the 'Stampede' cultivar of Jerusalem Artichoke, Helianthus tuberosus.  Now that they have reached 10-12 ft they are just starting to bloom.  I selected this cultivar for its more easily harvested tubers.  I've seen Jerusalem artichokes recommended for use in edible landscaping; however, to be effective a shorter earlier maturing selection would be more appropriate.  Before I put up the deer fence around the garden these plants were being grazed down to the ground on a regular basis.

These towering blooms are supposed to have a chocolaty scent.
I will need to pull some down to find out.

The color of the bracts ranges from pale green to pink.
On close examination  you can see the black dots
on the yellow flowers between the leafy bracts.

Among the deer resistant plants I put in around the garden were two native species of Bee Balm.  The Wild Bergamot, Monarda fistulosa, has been growing larger but has not bloomed this year.  However, the Spotted Bee Balm, M. punctata, has grown and flowered in the first year from seed.  These two plants have been untouched by the deer while the nearby Rudbeckia have been routinely munched.


While not native to the east coast the midwestern Blue Giant Hyssop, Agastache foeniculum, has been an excellent garden plant.  It is long blooming, attractive to pollinators, nicely textured and untouched by deer.  The biggest concern with this plant is its tendency to set a lot a seed.  We'll see what happens over the next couple of years.

There were lots of bluish spikes at the end of July.
These have faded to a mauve color in September,
but have maintained their shape.

In addition to these plants I have observed a number of truly wild flowers including Heal-all (Prunella vulgaris), Maryland Hawkweed (Heiracium marianum), Spanish Needles (Bidens bipinnata) and several goldenrods that I still need to ID.

As we transition into Fall there are a number of asters coming into bloom as well as a variety of goldenrods.  As I walk through the woods I will keep an eye on the ground for anything new

Co-existing with Nature

There is a conflict between nature and designed human space.  We like to have our nature neatened up and easily readable with beautiful plants arranged just so.  Nature is just do what it needs to survive, with each of its members seeking out their basic needs: food, shelter and reproduction.  Conflict arises when our focal plantings become a meal or natures breeding habitat becomes a lawn.

In putting in our new garden and new plantings I have been trying to work with nature to achieve my design goals and keep our vegetables ‘safe’ without destroying too much habitat or employing chemical weaponry. 

The double fence has been keeping the deer at bay.  The outer border has been planted with seedlings of
pollinator-friendly perennials.  I may not get too many flowers this year as these plants get established.

To help control garden insects I have left some meadow areas intact that provide habitat for predatory insects.  I have also planted a border around the garden with pollinator friendly plants.  In selecting these plants I chose ones that are listed as deer-resistant.  To combat the beetle population I have a jug of soapy water.  This works well on some of the bugs whose escape strategy is to drop to the ground.  I just hold the jug under them and they drop in when nudged.

Here are some photos of predatory insects that are in the yard.  In addition to these I have seen the 6-spotted Tiger Beetle, very cool!

This nymph of a Wheel Bug looks like something from
the movie, Starship Troopers.

This 2-inch mantid was hopping from stem to stem in a patch of
moss phlox as I was looking for a Tiger Beetle.

Compared to the green sweat flies, Long-legged flies are aptly named.  
This 1/2 inch fly is a general insect predator.

Most of the landscape plantings I have selected are not deer favorites.  For those plants that are on the deer’s menu I have been using repellents that are either scent-based (putrescent eggs) or taste-based (capsaicin/hot pepper).  The hot pepper spray seems to be effective at getting the deer or rabbits to stop feeding on a plant even after they have gotten a first taste. 

You can tell deer damage by the ragged edges they leave where they tear off leaves and stems (deer don't have upper incisors).  Rabbits have sharp teeth and will leave a clean cut, or they will consume a plant right to the ground.  

The following are lists of plants that have I have put in that are 1, deer candy; 2, occasionally browsed; 3, not bothered by deer.  It is still early in the season and these comments are based on how they treat the foliage.  Flowers will be another subject (see some comments).  While it is risky to proclaim a plant to be deer proof, I have not seen any damage to the plants on this list (yet).

The buds on this Magnolia were being eaten off
until I put on the chicken wire cage 

1.  Heavily Browsed

Apios americana 
Helianthus tuberosus 

Magnolia virginiana 

Rudbekia triloba 

Campanulastrum americanum* 

Zizia aurea* 

*These were very small and eaten to the ground so rabbits or some other critters were responsible for this damage. 

The pinnate leaves of the ground nut have been
chewed off in more exposed locations

This Jerusalem Artichoke was being browsed to the ground until the fences went up.
Now (June 27) these are 6-7 feet tall.

This Filipendula was nearly ready to bloom when the deer
ate off most of the upper growth.  Note the rough edge
where the deer ripped off the tip of the plant.

2.  Occasionally Browsed

Achillea millefolium (flowers were removed, the foliage was left behind)
Aronia melanocarpa 

Hibiscus moscheutos (just once)
Filipendula rubra (just once leaves and flower buds, not after hot pepper spray) 

Lobelia siphilitica 

Physostegia virginiana 

This Hibiscus had the tips chewed off, but no more
damage since I applied some hot pepper spray.

Rudbeckia hirta 

(The Lobelia had been untouched until yesterday.)













3.  Resistant, so far

Aquilegia canadensis 

Asclepias tuberosa 

Asclepias incarnata 
Ceoanthus americanus 

Chamaecrista fasciculata  
Chelone glabra 
Dicentra eximia 
Hedeoma pulegiodes 
Iris versicolor 
Monarda didyma 

Monarda fistulosa 

Monarda punctata 

Spiraea alba 

As far as keeping the critters out of the garden, the double fence method is still working.  I’ve been able to harvest snap peas, lettuce, chard and collards, so far.

I did notice some evidence of moles digging around the property.  For these I put down a perimeter treatment of MoleMax, a castor oil based product that moles and other burrowing species do not like. 

The Garden is 'IN'

Mother's Day has past so now it time to be planting the vegetable garden.  At least that is the tradition for many.  This year we had to days with frost warnings immediately after Mom's Day.  But now the weather is on an apparent warming trend.

In early March I laid out the beds for my new garden using techniques described in Weedless Gardening by Lee Reich.  The goal was to avoid having to till the new garden and remove all the grass and weeds.  The result has not been entirely weedless, but the amount of buried vegetation coming through has been manageable.  I think if I had waited until the grass had begun to grow and use up some of the energy stored in the roots there may have been few 'weeds' poking through.  More of the buried vegetation is working it way up along the seams between the cardboard and paper layers.  So for now I am just pulling off the tops of the grass and weeds to keep them from generating any new energy.

The fences are up and the garden is ready for planting.
Pollinator plants will go in along the outer fenceline.

The second phase of establishing the garden was to put up the fencing to keep the wildlife out.  My biggest concern is the deer, but there are plenty of other varmints (rabbits and ground hogs) to deal with as well.  I got a copy of Deerproofing Your Yard and Garden by Rhonda Hart.  I found this a very useful book that explains how deer operate and how manage them.

Separation between the fences is 3 ft, however 4 feet is commonly recommended.
Note the new compost enclosure in the back left, made from old wooden pallets
(Idea thanks to Washington County Master Gardeners).

The method I am trying out is a hybrid of the double-row fence and the invisible monofilament fence. The idea behind the double row fence is that while deer can jump high or long, they can't do both.  So a 4 foot fence that is also 4 feet deep is an effective deterrence. The invisible monofilament fence works by surprising deer with a barrier that they can not see.  In my case I had the remains of an electric fence to use to make my outer monofilament fence (I used the leftover electric fence wire).  I have 4 wires spaced out between 1 and 5 feet off of the ground.  For the inner barrier I have a very visible chicken wire fence.  The main purpose of the inner fence is to keep out the smaller mammals.  The chicken wire is partially buried under the mulch (flaring outward) to discourage tunneling into the garden (we'll see if that is enough).

The fencing was immediately effective.  The Sunchokes, Helianthus tuberosa, I planted a month ago had been repeatedly browsed upon, but after the fence was up they started getting taller.  About a week after putting up the fences a deer did breech the fence and it appeared to be a messy result for the deer, judging by the amount of fur left behind on the chicken wire.  I'm hoping that that was a learning experience and that it was sufficiently unpleasant.

Seeds for Peas, Collards, Chard and Lettuce sprouted within a week
and the Tomato and Pepper plants went in yesterday (5/15).

In the Deerproofing book the point is made to put up your deer deterrents before there is something to attract the deer.  So now that I've had the fence up for a couple of weeks I've started putting out the vegetables.

This year I am planning the garden based on companion planting ideas.  The plants in each of the 4 rows should all get along.  Here's whats going in:
Row 1:  Winter Squash, Snap Peas, Chard and Collards with Winter Savory
Row 2:  Pole Beans, Lettuce, Zucchini, Corn Salad and Arugula* with Nasturtums
Row 3:  Sunchokes, Tomatoes, Basil and Lettuce with Marigolds
Row 4:  Tomatoes, Peppers, Shallots and Garlic with more Nasturtums

*Arugula is in the cabbage family and may not be a good companion for the pole beans.  I should be harvesting these while young, so they may not interfere with the beans as they mature.

I'll plant the bean and squash seeds in a week or two (when the soil gets a little warmer and I should have the pollinator border plants by the end of May.

Starting a New Vegetable Garden

When we moved into our home in Watertown, MA starting a garden was easy.  The previous owner had established raised beds in a sunny opening in the back and along the south-side of the house.  The beds were small, but the soil was great.  Over the next 17 years the sunny spot in the back became only partly sunny (maybe 4-6 hours of full sun) due to the trees growing up and out.  Now with our new property in Maryland we are starting with a clean slate.  There are no established kitchen garden beds, so we need to determine which space works the best for us.

In selecting the site for the garden we considered accessibility to the garden, water, exposure, soil quality and protection from wildlife.  I consider solar exposure and soil quality as the most important factors; those are the most difficult to change.  All the convenient locations near the kitchen have less than optimal solar exposure.  A location off the garage offers better protection from wildlife, but it impinges on the septic field and is surrounded by trees (too much shade).

Garden site looking to the NNW.  Parts of the electric fence can be seen

The site I am considering with now is fairly open, with evergreens to the north and only a couple of trees nearby.  It has an open south-east aspect (the topography tilts to the SE), so it should warm-up quickly in the mornings and have good light throughout the day.  There is a water faucet nearby and the previous owners had installed an electric fence around the area, so we have the beginnings of an enclosure to keep the deer out.  I just need to take some soil samples for analysis to learn about any problems with the soil chemistry (crazy pH or nutrient deficiencies).

In addition to a deer fence I will surround the immediate area of the garden with a low mesh fence dug 6" into the ground to discourage the rabbits and ground hogs.  I have ordered a quantity of False Pennyroyal seeds (Hedeoma pulegioides) to plant on the perimeter.  The strongly aromatic scent is reported to repel many animals; we'll see just how effective it is.  Some other deer resistant plants planned for the perimeter are: Aquilegia canadensis, Asclepias tuberosa, Monarda fistulosa and Rudbeckia hirta.  These plants should also help in attracting pollinators.

Since I am planting a garden from scratch, I spent a little time reading about companion planting in order to make some better decisions about which plants will benefit from interplanting in the same part of the bed.  Two books that I found useful for this are "Companion Planting," by Bob Flowerdew and "Little House in the Suburbs," by Deanna Caswell and Daisy Siskin.  I can not speak about the benefits of companion planting yet, but these books did offer some explanation for some of my past vegetable garden failures such as Kohlrabi with Pole Beans and Snap Peas with Tomatoes.

Since I am interested in growing Native Edibles as well as 'regular' vegetables, I have ordered some tubers of Jerusalem Artichoke, Helianthus tuberosa, known as a Sunchoke in culinary circles.  These can get out of control on their own, so we will need to harvest the tubers annually to keep them in check.

I have also ordered some tubers of Groundnut, Apios americana.  They can be used like potatoes, but have a nutty flavor.  These sprawling vines may find their home along the shady woodland edge, rather than the center of the garden, for both cultural as well as aesthetic reasons.

To prepare the planting beds I will be using techniques described in Lee Reich's book "Weedless Gardening."  This is a top down method where the existing plants are cut to the ground then covered with multiple layers of paper.  NO DIGGING!  After wetting the paper it is covered with several inches of weed-free material.  In my case this will be soil that I will plant seed directly into.  For the garden paths I will use cardboard cover with wood mulch as a more resistant barrier layer.  The existing plants are smothered and since the soil was not turned over no new weeds from the seed bank are brought to the surface.  I will refer you to this easy reading book to get the details.

I've seen this technique work successfully for converting lawns to ground cover beds.  This will be the first time I've tried it over a more robust planting.  Since we still have loads of paper and cardboard left over from our move this is a perfect way to use existing resources.  The only materials I will need to bring on site are a couple of yards of planting soil and some organic fertilizer.  The best part of this method is that I will not need to turn over a large mass of the soil, only to be followed by a long season of weeding.

I will update this information as the garden installation moves along.
