Neat Plant Alert: Old Red Buckeye Across From Clinton School

What a welcome sight the red buckeye (Aesculus pavia) is in a spring season of so many colorless, wind-pollinated trees and shrubs.

The common, cheerful plants grow nearly statewide, leafing out well before the spring starting gun is fired and bearing panicles of showy red flowers to attract the birds, hummingbirds and bumblebees.

This old red buckeye tree is worth a visit; it grows directly across the road from the parking lot of the Clinton School on East 3rd Street in Little Rock.

Red buckeyes typically live as understory shrubs, but ambitious or lucky plants can grow 25-30 feet high. The current state champion, from Ashdown in Little River County, measures 23 feet high with a trunk diameter of more than 8 inches.

The buckeye genus comprises about a dozen species of Northern Hemisphere trees and shrubs, almost evenly split between the New World and the Old.

Seven species occur in North America: 1 in California and 5 in the East, with 2 in Arkansas—Ohio buckeye with yellow flowers is restricted here to the Ouachita and Ozark Highlands. Add to those the exotic horse-chestnut of Eurasia, Aesculus hippocastanum, which sporadically escapes cultivation in both the East and Pacific Northwest.

As spectacular as the flowers are, the buckeye takes its name from the large and strikingly colored seeds, with dark seed coat and pale placental scar. The British call them conkers. In America, they’re carried as good luck charms. However, anecdotal evidence from back in my teaching days suggests that their powers are limited—they were used instead of studying by a lot of my students on Botany and Regional Flora test days, but to no apparent effect.

Meet the Plant: Rue Anemone

Rue Anemone (Thalictrum (Anemonella) thalictroides) is a native perennial occurring throughout the woodlands of eastern US.

rue1

The common name is based on the appearance of the leaves being similar to those of an anemone as well as meadow rue.  The white to pink, cup-shaped flowers occur in umbels on slender stems in early spring, blooming for three weeks.

rue2

Flowers have 5-11 petal-like sepals that may be white to pink with pink flowers fading to a lighter shade with age.  Flowers are about 1 inch wide.   This non-aggressive plant does well in well drained soil of a garden setting under deciduous trees.  Plant height varies from three to six inches.

Rue anemone is common throughout the state in undisturbed hardwoods and it’s blooming now.  False rue anemone (Enemion [Isopyrum] biternatum) is an uncommon look-alike to keep an eye out for.

Meet the Tree: Toothache Tree

Toothache tree, Zanthoxylum clava-herculis, is surely one of Arkansas’ most intriguing native plants.

If you haven’t been introduced, chew on a twig or a piece of bark for a few minutes and feel your mouth and tongue start to tickle and go numb.

(Please be sure that you have correctly identified the tree and you are not in fact chewing on a poison-ivy vine that might be climbing the trunk.)

Toothache tree (tickle tongue or prickly-ash or Hercules’ club) is covered with prickles from the compound leaves to the twigs and bark.

The conical to flattened bark projections are especially interesting, each with prominent layers of cork tipped with a sharp, delicate spine.

Toothache tree occurs in the southwestern half to two-thirds of the state on a variety of upland and poorly drained sites.

It blooms in the spring–pretty, but nothing spectacular. The species is a member of the citrus family, and like our wafer-ash (or hop tree) is a host for giant swallowtail butterfly larvae.

A second species, Z. americanum, is rare in northern Arkansas.

The only other Arkansas trees with similar bark architecture are the sugarberries and hackberries, Celtis species, with amorphous, corky, wart-like protuberances.
