Blue eyed grass (Sisyrinchium spp.) ~ Midfield, Texas
Despite similarities among the buds shown in my previous post, the flowers themselves may not immediately suggest their membership in the iris family. When I met blue-eyed grass, it certainly didn’t seem iris-like. Only later did I learn that the rhizomes from which it grows, its tall, blade-like foliage, and its six petals all point to its connection to our more familiar irises.
Despite its common name, it isn’t a grass; it’s often lavender, violet, or white rather than blue; and the ‘eye’ in the center of the flower is yellow. Its name isn’t always hyphenated, but when it is, ‘blue eyed-grass’ would be a better choice than ‘blue-eyed grass.’
Blue-eyed grass spreads along roadsides and across fields in huge numbers, but I seldom encounter dense colonies of prairie nymphs. Individual flowers spreading across a large area seem more common, but their delicate color and intricate design make even a single flower worthy of attention.

The flowers bloom in succession over a two to three week period in early to late spring. Each flower lasts only a day, opening above narrow, sword-shaped leaves in the morning and closing by late afternoon.
The flowers themselves are two to three inches across, and their height seems to depend on whether mowing has occurred. Along roadsides or in cemeteries, they may be only a few inches tall, but on prairies or untended land, they often grow to be six to twelve inches in height. Rich in pollen and nectar, they hold special appeal for hoverflies and native bees.
Purple pleatleaf, sometimes called propeller flower, is found in the eastern third of Texas. Unlike blue-eyed grass or the prairie nymph, this is a flower that prefers a bit of shade. It’s often found along woodland edges; these were blooming in the Big Thicket, alongside a road leading to the Sundew Trail.
The ‘pleat’ in the name comes from the plant’s leaves, which are folded along their length as they rise from the ground. Taller than the prairie nymph, with a mostly leafless stem, purple pleat-leaf seems to me the most iris–like of the trio, and it certainly is eye-catching.

To my chagrin, I realized only this morning that I failed to mention another member of the iris family in these posts: a favorite from the hill country that I’ve seen only twice. As the saying goes, “So many flowers, so little time!” ~ so I’ll save the neglected one for another time.
