I love this plant! I had it in a pot for a couple of years, then I transplanted it in the ground in early spring. My dogs while chasing squirrels broke all of the main branches off...... I thought for sure it wouldn't come back, well it did better than ever! I also have found that here in Zone 10 that it does better with morning sun to early afternoon sun.

I am not in a hardy zone, but grow it in a pot. I love iochromas. They give non-stop blooms.

Just acquired this plant (5-29-04); the (private) grower didn't know the name of it but called it the "HOT PLANT". When it is in bloom she can't keep it in goes like "HOT" cakes! She propagates it by cuttings and it does great for her (in shade). We are in zone 9 or 10 depending on which map you look at....45 miles from Gulf of Mexico in SW Louisiana. I'm so excited about acquiring this plant! Jackie Trouard, Moss Bluff Louisiana
