It's late August and I'm seeing Red.....and some other colors, too


In direct sun the red of this Lobelia stands in
perfect contrast to the green background.
This is the first year for my Cardinal Flowers, Lobelia cardinalis, to bloom and I must say it really pops on a grass green back ground.  I planted these as seedlings last year and they never got very big.  Part of that was due to deer browsing.  This year the deer ate a little early in the season, but did not come back after the buds began to form.  I don't know if that has to do with a change in the taste of the maturing plant, or if it was due to spraying the plants with a new deer repellent, Bobbex.  Besides delighting the eye, the cardinal flowers are a big hit with the butterflies.

This Scarlet Sage is growing in a partly sunny garden.


Before I had a place with moist soil I relied on this Blood or Scarlet Sage, Salvia coccinea, to get an intense shade of red in late summer.  It grows well in moist to dry soils and will tolerate some shade.  Scarlet sage is usually grown as an annual.  In the past it has reseeded itself in my warm zone 6 garden in Boston.  We'll see how it does in my less protected Maryland garden next year.  I have seen hummingbirds feeding on this sage, as well as many bees. 

This photo taken early in the morning contrasts the yellow of evening primrose,
Oenothera biennis, with the violet of NY ironweed, Veronia noreboracensis.
These two tall plants complement each other toward the back of this planting.
Another major presence in the garden is New York Ironweed, Veronia noveboracensis.  This year they are growing to 8 feet.  I cut one back by 1/3 at the beginning of July and it quickly grew back fuller than before.  This plant is very attractive to butterflies, it has about as many as a nearby exotic butterfly bush.

Wingstem is named for the rough appendages growing along its stems.



The predominant open meadow flower of late summer here is WingstemVerbesina alternifolia.   In the full sun they grow straight up to 3 to over 8 feet.   I have allowed a few to grow in the partly sunny gardens near the house.  Under these conditions they still grow tall, but they lean forward to get more sun, eventually flopping over.  Blooming period is about a month long, mid August to late September.

Under the shade of pines I am trying out several species of Goldenrods. The first to bloom is Elm-leaved Goldenrod, Solidago ulmnifolia.  As with the cardinal flower, these were browsed heavily by the deer in their first year, but this year they are reaching bloom (maybe with the help of Bobbex).  Other goldenrods I am trying in the shade are Zigzag, Bluestemmed and Showy Goldenrods.













The little whitish flowers of Jumpseed wiggle their way out of the undergrowth.
The foliage of this plant is tattered since it is often eaten by some as yet unidentified insects.
Another shade-tolerant native that is blooming now is Virginia Jumpseed, Persicaria virginiana.  Not particularly showy by itself, en mass it adds some interesting texture to a shady scene.  There are some forms of this plant with more colorful leaves and red flowers, but those are not in bloom just yet. 




Aromatic Aster is just beginning its long season of bloom.
One of the newer additions to the garden is Aromatic Aster, Symphyotrichum oblongifolius 'October Skies'.  Despite its name it has started blooming in late August (this cultivar is actually named for the flower color, not the bloom time).  This cultivar is compact and densly blooming.  Growing to about 2 feet tall it is a great choice for near the front of a border.  In addition to the good-sized blooms the foliage of this little bush has a pleasing scent.

I just wanted to share this last image of a patriotic color combination of Hibiscus moscheutos, Lobelia cardinalis, and L. siphilitica. It's not a great photographic composition, but it is an example of red, white and blue native flowers blooming at the same time (mid-August).  

This photo could have been improved had I bothered to remove the
chicken wire protection from around the Hardy Hibiscus.

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

Winter Field Trip

So after writing about the 'Winter Weeds' around my house for a couple of weeks I decided to take a walk through a nearby meadow to see what's still standing.  For me the closest meadow is Rock Meadow, in Belmont, MA.  This erstwhile farm has been conservation land for the town of Belmont since 1969.  With decreasing maintenance budgets over the years this area was undergoing succession with open meadows being closed up with a variety of native and non-native, invasive species.  This severely  degraded its value as a bird nesting habitat and reduced it general value as a recreational space.  In 2005 the Friends of Rock Meadow worked with the town in securing funds to do a renovation.  Most of this work was completed between 2007 and 2009, with the removal of many invasive plants, clearing shrubbery from the meadow and improving trails.  So with map in hand I set out to see what interesting plants I could find...

The burrs on this Burdock catch the afternoon sun
as easily as they do to a passing hiker.
The first plant I came across was Burdock.  This old world introduction is a common weed of waste spaces, but its strong structure helps it persist in the winter landscape.  The burs on the seed pod are hooked which help them attach to passing animals, thus dispersing the seed to a wider area.







Next I walked by a thicket rich with Red Twig Dogwood.  I am assuming these are the native Cornus sericea (formerly, C. stolonifera), even with leaves and flowers some of these species are difficult to tell apart.

The Red-twig Dogwood was easily identified among
all the other brown branches in the thicket.







Large sections of Rock Meadow are consistently wet.  These areas are easily identified by their large populations of Cattails.  There are two common species in the Northeast, one with broad leaves and one with narrow (Typha latifolia and T. angustifolia, respectively).  I did not investigate which was present, or if both were there.

One of the wet areas in Rock Meadow that is home to Cattails

Steeple Bush, just upstream
of a wet meadow.
Steeple Bush (Spiraea tomentosa) is another native spirea.  Unlike the Meadowsweet I have growing at home, the flowers of Steeple Bush are held in tightly erect panicles.  Also I found it here, Steeple Bush prefers moister soils.

While not a true pre-Colombian native species, Queen Anne's Lace has become naturalized throughout North America.  Even without its flower petals, this plant still has a presence in the winter landscape.  

The bare bones of Queen Anne's Lace

The few remaining seeds on this Little Bluestem
still catch the  winter sunlight.


Little Bluestem is a widespread native grass.  It seems to look its best growing on really poor soils and is often seen growing along the highway.  In richer soils it gets tall and floppy.  In the fall and winter it can be picked out by its orangy appearance and the way that the fuzzy seeds catch the light.



One plant I almost passed right by was this Tower Mustard.  It just looked like some sticks poking out of the ground.  On closer examination I noticed the dimpled membranes that once held the seed in an alternating pattern.  I didn't know this plant at first, but I looked in my copy of  'Weeds in Winter' and it led me to the mustard family.  After that, I was able to locate the species by referring to my copy of Newcomb's.

The seed pods of Tower Mustard still show
the impressions of the seeds they held.
The opened seed pods of Evening Primrose
 look like dried flowers.

Evening Primrose is a plant that is easy to recognize in its dried form.  When I walked by I realized that I knew this plant, I just could not remember its name.  The stiff, four-parted seed capsules on the tall, upright stems are unique and hard to forget.  I quickly flipped through the field guide until I found a drawing that matched this plant dead on.



I'm pretty sure this is Sweet Everlasting.
Had I used my nose as well as my eyes I would no for sure.
After returning to the path I looked down and saw another familiar plant.  There was a single stem of what I believe was Sweet Everlasting (Pseudognaphalium obtussifolium).  However, it could also have been Pearly Everlasting (Anaphalis margaritacea) which also has woolly stems and leaves and persistent papery bracts.  Crushing a flower would have told me which, Sweet Everlasting has a sweet, tobaccoy scent, while Pearly Everlasting has no smell.  Also, the bracts of Sweet Everlasting have a dingy tone, while those of Pearly Everlasting are reported to stay white (forever?).

As I moved into a shadier area, a large patch of Raspberry vines became evident.  These stood out as a purple mass of branches against an otherwise dull brown background.  Closer examination showed the little red thorns on the purple branches.  A couple of years ago I attempted to ID some raspberries but was quickly overwhelmed by the possibilities.  Right now I will just appreciate their contrast to the shades of brown.

Raspberries of some sort; the thorns are too small to be Blackberry

When I first saw these berries I thought this might be an Arailia of some sort.
A little research indicated that this was actually Carrion-Flower.
Carrion-flower was a surprise find as I was heading back to the parking lot.  Most of the members of the genus Smilax are rather unpleasant to deal with, like Catbriar (Smilax rotundifolia), with its tangle of thorny branches.  Carrion-flower, S. herbacea, on the other hand, has few, if any, thorns and only grows to about 8' in length.  As its common name indicates, the flowers have an unpleasant scent.




While Rock Meadow has been cleaned up of many of its  invasive species, some still remain.  In the winter months Winged Euonymus is easily recognized by the little wing-like projections along its stems.  Another common invasive is Black Swallowwort.  It can be recognized by the remains of its seed pod that looks like a dried leaf.  This vine is very hard to eradicate since it will resprout from small fragments of roots left behind after pulling or digging.

The arrow in the photo points to some of the wings
on this Winged Euonymus.
The old seed pods on this Black Swallowwort looks kind of like those of Milkweed.  In fact these are both members of the Asclepiadaceae family.
