The Irises of Tosohatchee, March 28, 2012

The Tosohatchee WMA is known for its prodigious displays of irises in spring. I first saw them almost exactly one year ago during my first visit to Tosohatchee. The irises then were beautiful and impressive. I had not expected to see so many. On this visit they were even more spectacular!

I've placed all the iris photos at the beginning of this post, although they were found in several places: the ditch on the south sides of Beehead Rd and Power Line Rd and in the field beneath the power lines on the north side of Power Line Rd.

This post also includes about 40 other species of wildflowers and plants, all shown in the order in which I encountered them. Three of the species are new to this blog.

Dixie iris, prairie iris (Iris hexagona, Iridaceae)
Native

We spotted our first few irises in the ditch on the south side of Beehead Rd.

Irises along Power Line Rd.

We found large numbers of irises in the ditch along the south side of Power Line Rd.

The iris blossom consists of 3 sepals and 3 petals. The sepals curve downward from the center of the blossom and are known as "falls." The petals are smaller and narrower than the sepals; they display up from the center and are known as "standards." The bright yellow patch on the sepals is known as the "signal." The veins and signal guide pollinators to the nectar.

Irises and Butterflies

The irises attracted many butterflies, especially two kinds of Swallowtails. The mostly black butterflies with yellow spots are Eastern Black Swallowtails. The mostly yellow ones with black "tiger" stripes on the leading edge of the wings are Eastern Tiger Swallowtails.

White Irises

We found one small patch of the rare white form of iris. They were growing in a boggy area beneath the power lines, north of Power Line Rd.

Dark Irises

Some dark blue irises were growing near the white irises.
