Dear Cynthia and all.
There is no species with this name, but the variety I. 
laevigata 'Colchesterensis' is well known and grown. This is one of 
the most aquatic of all irises. It should be hardy to Zone 4 at 
least, but not sure how it will do in a milder climate of Texas.

I'd soak the seed for a few days until all have sunk, Change 
water daily.

Plant in good garden soil, kept moist and place outdoors in a 
cool spot. As the seeds germinate continue to keep evenly moist. I. 
laevigata does best submerged in water from just over the 'ankles' to 
'knee deep'.

It's a beauty, too.bestJim W.
