Texas Star Hibiscus in zone 5

I have several young Texas Star Hibiscus that are doing well. In researching I found most data indicates these hardy to zone 6. Any zone 5ers have them survive zone 5 winters? If so did you mulch them heavy?

RE: Texas Star Hibiscus in zone 5

Hi Ron,
I have managed to overwinter a lot of hardy hibs here in Quebec and managed to get the Texas star to overwinter for 2 winters before it gave up. I apply a very thick (i.e. 2 feet) deep mulch of anything I can get my hands on in the autumn, and make sure it extends way past the drip line of the plants. In the spring I usually wait until the first or second week of June to start poking around in the mulch to see if there are any shoots.
Good luck
