Wild irises along Brazoria County Road 306
After returning from my recent foray into the wilds of Bluebonnetland, I realized I was in danger of repeating a mistake I’ve made in the past. Despite knowing last year’s iris leaves had emerged in the ditches surrounding the San Bernard Wildlife Refuge, I put off a return visit; by the time I saw the irises again, the flowers were gone.
Not wanting to miss them this year, I decided to make a quick trip to the refuge to see if a few irises might still be blooming. They were: another form of ditch diamond to enjoy.
A different sort of flag
Everyone seems to agree that at least three iris species are native to Texas. This Southern Blue Flag (Iris virginica) may be the best known. I first heard the phrase ‘flag pond’ after moving to Texas, and misinterpreted the phrase. I assumed it meant a pond with a flag pole next to it. A pond filled with irises never occurred to me.
Two to three feet tall, Blue Flags can vary in color from very light blue to purple, leading me to suspect that the next two photos also show Blue Flags.
The Zigzag iris (Iris brevicaulis) has different growth habits. Flowers are borne on sprawling stems which typically zig-zag to a height of no more than fives inches. The specific epithet brevicaulis means ‘short-stemmed,’ and the long, strap-like green leaves often hide the blooms.

Color variations also exist among Zigzag Iris. While some sites describe the flower as lavender, others mention purple and yellow as possibilities. Given their short stature and the length of their sepals — substantially longer than their petals — I suspect this next pair might be Zigzag iris as well.
The colonies were pretty when seen from the road, but only a walk among them revealed their variety of color and form: except, of course, for the yellow iris, which demanded to be noticed.
