Winter Weeds, Part 1

On nice winter days it is fun and interesting to take a walk through some of the wilder areas to see what plants are still standing.  An excellent guide book for this is Weeds in Winter by Lauren Brown.   This book has all kinds of useful information for winter plant ID in New England.  There’s a glossary of terms, a dichotomous key for plants described in the book and some really great illustrations of the winter appearance of these plants.  

Since this winter has been so mild in southern New England, I was able to find many of these plants right around my house.  These normally would have been crushed under piles of snow.  In fact, I found so many of them I need to split this post into two parts.  Most of these photos were taken at the end of January this year.  Here is the first of two installments of photos of my winter weeds.  

This Prairie Aster retains its strong
stems through the winter

These photos are roughly in alphabetical order.  I had already decided on the order when I remembered the name changes for the asters, so Symphyotrichum is coming first.

Aster can be difficult to ID in the winter.
Fortunately, I remembered which is which in this case.

Many of these native asters have long lasting stems.  For example, the 'bush' on the far right in the topmost photo is a Prairie Aster.

The Bigleaf Aster still has some of its seeds.

When I came across this old stem of the American Bellflower I was not sure what I was looking at.  After I few minutes I remember what had been growing in that location and narrowed it down to this species.  One advantage of using the plants around the house is that ID is a lot easier than when working in the field.

American Bellflower has distinctive seed capsules.

Sweet Pepper Bush looks like a tangle of branches in winter.  Closer examination of the older branches shows that it has exfoliating bark.  It is more easily identified by its flower spikes that stay on through the winter.

The long styles of the pistil are retained
on these dried Sweet Pepper Bush flowers.

I usually don't see the Pink Tickseed in winter.  It's growing out of the driveway and is usually covered with snow.  On close examination you can see the narrow little leaves have already started coming up.

Pink Tickseed is only 6-8" tall.

The new buds on this Sweetfern are beginning to swell.
The hairs on the stem really show up in the afternoon light.

The low angle of the sun really enhances the appearance of the stems and spent flowers of these plants.  This is particularly true for the taller plants like these River Oats.

The seeds of the River Oats are shed
slowly over the coarse of the winter.

Purple Coneflower is one of the easier plants to identify.  The old flowers retain their cone-shape even thought the seeds are long gone, either eaten by birds or scattered in the wind.

Seeds of the Purple Coneflower are all gone now

Even though it's dried up American Pennyroyal
still has its minty scent.

The last plant in this post is the American Pennyroyal.  This low growing annual is usually buried under snow there is nothing left of it when the snow melts.  The dried calyxes are arranged in whorls around the stem.  These are much easier to see now that all the leaves are gone.

Well pregame is nearly over, so it's time to close down the computer and start watching the Super Bowl.

Go Pats!!!!

Rebirth-- Spring in New England

I had a wonderful visit to St. John, USVI, with all of its lush vegetation and quiet beaches, but you can’t beat coming back to springtime in New England. After 5+ months of grayness, color has popped out everywhere. All that new foliage is fresh and green and many of the trees and shrubs are blooming. As Laurrie commented in a recent blog post ‘The Thrill is Gone’ . We in zone 5 and below have to wait longer than many – but experiencing the rebirth first hand sure beats looking a pictures.

Here’s a look at some of the native plants that are coming out around my house in the past few days.

The common blue violet, which I used to battle against until I learned that it was a native species, was popping up through my unmown lawn. Eastern columbine is about to bloom. This one is the result of self seeding. I also caught this sweetfern in bloom with the small red female flower below the male catkins.  This little flower is really easy to miss.

In my ‘woodland’ garden there are a number of perennials returning. This garden is under a Norway Maple, so it is hardly a natural environment for these plants, but the ones that grow here are tough competitors.

Best results go to the Wild Bleeding Heart, which is actually expanding its bounds. Lowbush blueberry is blooming well this year. The Twinleaf and Bellwort have been coming back for 3-4 years now, with some indication that they are beginning to spread. Last year I was fortunate to capture the Twinleaf in bloom. The intense white flowers only last a day, but the foliage alone can carry the show.  There are also a variety of native ferns putting up their fiddleheads.

Coming soon are the huckleberry and barren strawberry. I’ll get to those later.

What’s Blooming around Home

It’s still too early for a lot of spring flowers in the Boston area, but the great weather (after the recent flooding) this weekend got me out to look at the garden a little more closely. Most of the visual excitement is around the naturalized, non-native bulbs like Chionodoxa, Scilla and crocus. I was pleased to see how many bees were visiting what I believe to be these white Chionodoxa. (I am a little uncertain here because of the blue anthers – anyone have an alternate ID for this plant? It would be much appreciated.)  For next year I think I will try for more native spring flowers like Bloodroot, Dog-tooth violets and the Camas Lily, Camassia quamash.

These white flowers pictured above are actually Scilla mischtschenkoana, White or Early Squill.

While not open yet, the male catkins of my Sweet Fern (Comptonia peregrina) are getting plumper and have become noticeable. Also the hairs on the reddish branches really catch the afternoon light and make them glow.

 

Another sign of spring is when the Yews release tons of yellow pollen. This is the first year that I have really looked closely at the flowers. I noticed a difference between the flowers of two of my (unknown) cultivars. Also now is a good time to do some structural pruning on these to let more light in and stimulate some growth on the interior.

 What I am most pleased about seeing was the return of what I believe to be a Spring Blue-Eyed Mary from some seed that I had sown 2 years ago. I’ll keep a close watch on this seedling and let you know what it grows into.

Another pleasant surprise was a clump of Strawberry Spinach (Chenopodium capitatum) that overwintered. Normally this is considered to be an annual, but this plant did not mature last year, so I expect that it will finish out its lifecycle this year with some bright red berries. Check out the link for a seed source and more information on this native.

One thing I have noticed with some of the native annuals that I have tested is that those that do not flower and seed the first year will over-winter to complete their life cycle the following year.
