Winter Plums

American Plum
Prunus americana


The American plum thicket at the Arboretum just gets bigger and thicker every year. Most folks love the loads of fragrant flowers that are the first to bloom in spring, but I think the plums are beautiful in winter when the entire thicket is covered with snow.


Wild plums are true American natives. They are not cultivated plums gone wild; they were here long before the colonists and are found in 44 states and 5 Canadian provinces. Almost everyone has had the pleasure of trying to eat the astringent fruit right off a wild branch. Although many of the big thickets have been cleaned from the cropland fence lines, you can find enough wild plums to make wild plum jelly and jam.


For most small animals, insects and birds, a large plum thicket is a miniature wildlife preserve. As I walked by the Arboretum’s plum thicket after last week’s snow storm I flushed up 2 pheasants, saw 2 other species of birds and the tracks of raccoon, rabbits and mice. For these critters, the thicket is a warm, protective place to nest and hide; safe from predators and bad weather.


Looking at the remains of four bird’s nests and the multiple tracks leading into the plum brambles, I wondered if a wild American plum thicket might be just the woody plant I am looking for in my big yard. I have a neglected, partly shady corner with lots of room for a spreading thicket. Perhaps a miniature wildlife preserve is just what the neighborhood needs.

Tall Grass Prairie Flowers in Bloom

Walking through the prairie yesterday afternoon, I looked up and saw the waxing moon, a few more days to the full moon. The changing of the moon seems to coincide with the transitions I see in the prairie. The pale purple coneflowers heads are dark with seeds and the flowering spiderwort, thimbleflowers, larspurs and baptisias are now more a study of seeds, not petals.

With the fading of the early wildflowers, new summer wildflowers are getting my attention and the prairie grasses are starting to take their rightful place. Prairie clover, one of my favorite prairie flowers is now in bloom and echinacea purpurea the stiffer upright coneflower is just starting another purple show. Prairie coreopsis, lead plant, wild quinine and a few Mexican hats (Ratibida columnifera) join the new list of flowers I keep at my desk.

Walking back through the prairie, I notice some a few new flowering balls emerging from a Rattlesnake Master, Eryngium yuccifolium. What a great plant! This time I was lucky enough to have just enough battery in my camera to catch a picture of the small flowers that bloom hidden, nestled inside their prickly bracts.

A Lesson in Tree Identification

Andy Schmitz, the Arboretum's general manager came into the office yesterday chuckling over a list of trees he made while weeding under our weeping crabapple trees. He had a list of 11 different species of tree and shrub saplings under the 5 Louisa crabapples we have in our collection. These weeping crabapple trees touch the ground and provide a nice cover for the seeds left by birds.
The list includes:
Black Cherry
Hackberry
Dogwood
Cranberry Bush Viburnum
Mulberry
Cat Briar
Eastern Redcedar
Cottonwood
Multiflora Rose
Tree of Heaven
Poison Ivy

As I tell the kids; What's a weed?
A plant growing where it is not wanted.

Second Friday Nature Club

For the last year, a homeschool group has been visiting the Arboretum the second Friday of each month. We started in July and went on a prairie flower walk looking for pollen. Over the next 10 months we have watched those flowers go to seed and become winter food for birds.

We have discovered muskrats, slid on ice, watched the trees bud and watched the Arboretum come into bloom again. It has been an extremely rewarding experience and given me a new perspective on what is good environmental education.

We are expanding the 2nd Friday Nature Club over the summer to include an evening group. Let's take advantage of the long evenings to walk and enjoy all that nature has to offer. You know the old adage about stopping to smell the flowers? Let's stop and look for pollen, or find caterpillars and examine dragonflies.

Current scientific evidence indicates that frequent, positive experiences in nature benefits children. This is true for adults as well. You wouldn't think twice about not taking kids to the library regularly, perhaps it's time to schedule a regular trip into nature.

2nd Friday Nature Club
6:00 PM until 7:30 PM
June through September
The group will decide on a winter weekend meeting time.
The nature club is free for a one time trial. To join for the year, please become a family member.

The Afternoon group keeps a nature blog of their walks and other discoveries they make on thier own. Check it out- http://heednature.blogspot.com/
