Rodney Barton's Brevicaulis Page
Rodney Barton's Brevicaulis Page previously was part of his North American Native Iris site, which is no longer active. Rodney generously permitted a move of the Louisiana iris species pages to the Zydeco species section. Rodney lives and grows irises in Hickory Creek, TX, near Dallas.

in warmer climes.

and protect rhizomes from sun burn.

best planted before the seeds dry.
- Comments: Generally easy. Will grow in "border garden"

me. Goes dormant in the summer here and often doesn't put on fall growth
like the rest of the series. Never lays over in my garden.
