Here in the Houston area they can grown to well over 10 feet tall with the right soil, Mostly they seem to stay at about 6 feet but can be kept pruned back if needed. They do okay here with either morning sun and afternoon shade or Morning shade and evening sun but seem to enjoy full sun for best blooming results. Each bloom can produce about 15 seeds so you will end up giving seeds away or growing a lot more plants. I find that I usually am able to find someone local who wants my extra plants as I have gotten carried away at times.

Those who grow Texas Star Hibiscus should have lots of seeds each year as even one bloom about 30 seeds and they sure do start easy. Here I start them anytime of the year and end up with too many seeds each time. I have never had any white Star Hibiscus to produce or someone send the wrong seeds. but I do enjoy the Red blooms. I also enjoy the rose-of-Sharon blooms which are hardier the the Florida-Louisiana-Texas Star Hibiscus. I say that because they are native to Florida and Louisiana but ended up being called Texas Star Hibiscus.

We trim them to the ground in Dallas because they always die back here. They emerge from the roots later than a lot of other things. If dormant, could wait to see if it emerges from stems in your zone.

I’m looking for some Tx white star hibiscus seeds, anyone out there have any they would like to swap for a different color hibiscus? Thanks
