2013 Native Woodland Plants and Spring Ephemerals

Annette MaCoy
I love learning new things, even when I think I already know a bit about a subject.  Such was the case on Saturday, April 20th, when I attended the workshop at Spring Haven Nurseries on Native Woodland Plants and Spring Ephemerals hosted by the Cumberland Valley Woodland Owners Association and taught by Cumberland County consumer horticulture educator Annette Macoy.

Virginia Bluebells - Mertensia virginica in Eckhart Woods

For example, I had assumed that the word "ephemeral" referred to the short bloom period of the flowers. Not so.

Toadshade Trillium - Trillium sessile in Eckhart Garden
True perennial spring ephemerals are plants that have evolved to complete their entire season in the relatively short time frame of early spring, before deciduous tree leaf out.

Hipatica nobilis var. acuta - (Sharp lobed Hipatica) - Spring Haven
Trillium grandiflorum propagation bed - Spring Haven
They emerge early, leaf out, bloom, set seeds, and their leaves die back completely, soon after the deciduous trees around them leaf out. As such, they really are not "shade loving" plants per se, but take advantage of the sun that's available during that short season.
Squirrel Corn - Dicentra canadensis - Spring Haven
You won't find them, for example, in forests dominated by evergreens, since the shade the evergreens cast is year-round.  It explains why the "True Spring Ephemerals" I have in my shade garden don't do as well there as the ones that pop up in my woods.

Brunnera macrophylla - Siberian Bugloss (Eastern European) - Spring Haven
My shade garden is largely shaded by my house, which obviously doesn't have a dormant period before leaf out.

Dicentra cucullaria - Dutchman's Breeches - Spring Haven Garden
There are spots however, where I think I can move them, in order to take advantage of this new knowledge and provide the environment that better matches their life cycle.

Bloodroot - Sanguinaria canadensis - Spring Haven
Conversely, some of the Native Spring Woodland species I had categorized as ephemerals, are true shade loving plants, with a much longer season. The blooming period of their flowers may be brief, but their leaves persist for a much longer time throughout the season, and will only die back (senesce) when exposed to too much direct sun or heat, well into the summer.
Bloodroot - Sanguinaria canadensis - Spring Haven
They may not do well in their natural setting, either, if their shade cover comes down via natural, or harvested tree toppling, creating an open sunlit clearing in the forest, until something grows up there to again provide the necessary shade.

Twinleaf - Jeffersonia diphylla - Eckhart Garden
The other major piece of knowledge gained about ephemerals is their evolved method of seed dispersal.  According to what Annette dubbed the "MaCoy Hypothesis" (requiring further funding and study, any graduate students out there reading), their short life cycle dictates that they don't have the sun-generated carbohydrate reserves to create a true fruit, attracting browsers to eat it and disperse their seeds widely while foraging.

Uvularia grandiflora - Merrybells in Eckhart Garden
Instead, they create a sorta fruitlette (my made up word) called an eliaosome, a small piece of carbohydrate flesh attached to the seed, that instead attracts ants who find them, take them back to their nests, eat the eliaosome, and leave the seed to germinate and spread the plants' genes.  The result, is that they do not spread very far from the original mother plant - a distance measured in yards, not miles, as in the case with bird or mammal dispersals.

Woodland Poppy Stylophorum diphyllum Spring Haven
This makes them more vulnerable to complete eradication in an area, without an easy means to recover, when their habitat is disturbed by tree harvesting, for example. The word scientists use for species with this method of seed dispersal is "myrmecochorous ", which we all got to practice pronouncing.

Here's a video on the subject, using Trilliums as an example:

Annette chose 10 plants to talk about - all native woodland species - but clarified whether they were a shade-loving species, or a true spring ephemeral, and provided information about their particulars. Later, we took a walk through the gardens and propagation beds at Spring Haven, to talk about these and other species, and see them growing.

Annette MaCoy with Display
Here are the ones Annette chose to highlight:
  • Virginia Blue Bells - Mertensia virginica - true spring ephemeral
  • Trillium - several species T. erectum, T. sessile, and T. grandiflorum - True ephemerals
  • Hepatica nobilis - two kinds - round lobes (var. obtusa) and pointed lobes (var. acuta) - not a true ephemeral, since the foliage actually persists year-round, until the new foliage emerges in spring.
  • Eastern Red Columbine Aquilegia canadensis - not an ephemeral, and I also learned that they evolved to be pollinated by hummingbirds.
  • Twin Leaf - Jeffersonia diphylla - Woodland shade species, not an ephemeral
  • Blood Root - Sanguinaria canadensis - Woodland shade species, not an ephemeral
  • Trout Lily - Erythonium americanum - True ephemeral (not pictured)
  • Skunk Cabbage Symplocarpus foetidus - Not a true ephemeral since the foliage persists until summer. (not pictured) more here.
  • Mayapple - Podophyllum peltatum - Not a true ephemeral, with an edible berry, but only when absolutely ripe. Poisonous otherwise. The foliage persists until the fruit ripens; it may senesce earlier if the summer is hot and dry. (not pictured)
  • Fringed Polygala, or Bird on the Wing  - Polygala paucifolia - not a true ephemeral, and a one I had not heard of before (not pictured.) - foliage persists.

Variegated Trillium?
This final picture came from the Facebook feed of Barry Glick, of Sunshine Farms and Gardens earlier this week.  While absolutely stunning, it turns out that these Trilliums are infected with mycoplasma bacteria, which will eventually cause the plant to no longer flower, so they must be quarantined from other trilliums to prevent the spread of the disease.

Previous blog posts about my then understanding of Spring Ephemerals can be found here and here.

Update: Wednesday, May 1, 2013.  Shoulda taken better notes.  I had Annette review, and she caught some errors - all in the area of whether or not the plant qualifies as a true ephemeral.  Corrections made.  Won't tell you what they are to avoid further embarrassment.

Gass Garden - We Have Signage!

Western, or Saskatoon Serviceberry - Amelanchier alnifolia
Friday, April 26th was a perfect day for gardening work, and the Gass Garden team started installing the new, permanent signage.  Linda Secrist was there to take pictures.

Herb Garden Workday

There were cars and trucks parked around the demo gardens Friday morning as Master Gardeners worked in the perennial, herb and Gass House gardens.

Herb Garden - April 2013
Planting, mulching and watering happened in the herb garden. Trailing germander (Teucrium Chamaedrys ‘Prostratum’) was pulled from the holding area and planted along the edge of one of the front beds. This is also known as the "poor man's boxwood” and is often seen at the edges in knot gardens or formal garden beds.

Trailing Germander

The Craft Garden
Sweet Annie (Artemisia annua)

Sweet Annie (Artemisia annua), used in making wreaths, potpourri and sachets, was planted. The leaves from mugwort (Artemisia vulgaris), pulled from the pollinator garden on Monday, are an excellent insect repellent and can be added to sachets for linen or clothes closets.

Globe amaranth plants (Gomphrena haageana ‘Strawberry Fields’) were added. The red globe amaranth adds bright red to any wreath or dried crafts and can be used as visual additions to dry potpourris.

Globe Amaranth

The garden includes violets, used for dried flower crafts, and lemon thyme (Thymus citriodorus) used for potpourris.
Also added were both red and yellow yarrow (Achillea millefolium) used in wreaths, arrangements and potpourris.

Yarrow 'Paprika' (L) and Yarrow 'Schwellenberg' (R)

Queen Anne’s Lace (Daucus carota)  is used for arrangements, wreaths and as a visual to dry potpourris. Presumed to be named after Anne, Queen of Great Britain, the flower resembles lace. Although the tiny red center flower is thought to be a blood droplet where Anne pricked herself making lace, it is actually a flower colored by anthocyanin which attracts insects.

Queen Anne's Lace (Daucus carota)

Other plants to be planted in the near future are baby’s breath (Gypsophilia), lavender cotton/santolina (Santolina chamaecyparissus), celosia, curry plant (Helichrysum italicum), scented geraniums, another scented thyme and Iris germanica var. florentina, also known as orris root, a fixative for scents in potpourris and cosmetics.

Curry Plant
The Dye Garden

This garden is a bit of a challenge as many of the plants are not commonly found in gardens. The binomials of some plants include “tinctor …” meaning to tint or dye. On order are madder (Rubia tinctorum), woad (Isatis tinctoria), dyer’s chamomile (Anthemis tinctoria) and indigo (Indigofera tinctoria). Only a goldenrod (Solidago spp.), claimed from the pollinator garden, has been planted so far.  Also planned are yarrow (Achillea), zinnias (Zinnia spp.), marigolds (Targetes spp.), saffron crocus (Crocus sativa) and a centerpiece plant, dyer’s broom (Genista tinctoria).

Dyer's Broom

Stay tuned for more on the herb garden as the weather turns warmer and the seedlings from the greenhouse can be moved to the various beds.

Container Garden Workshop - Saturday, April 27

MG Linda Horst Teaches the Basics
On Saturday, April 27th, 2013, Master Gardeners offerred their container gardening workshop, and MG Laurie Collins was there to record it.  I took the class back in 2010, and learned a bunch of stuff.

Enjoy the pictures.

After hearing the lecture, folks put together their container gardens to take home, ably assisted by other Master Gardeners, like Sally Dallago using plant material supplied for the workshop.

Pretty good results, I'd say.
