ViolaAnn,
The first link as I read it did state that the plants could be grown year round in zones 10a and 10b, but then as I read it, it stated that commercial growers should plant liners in summer and early fall for sale of gallon sized plants in the spring. Then said that they should plant liners later in the fall to grow qt. size plants for spring sale. Notice that the sales to retail customers would be all taking place in the spring.
The link listed below is a response to a person asking if it is true that there is a hosta that survives in Florida?
The response is "Yes" and states that regular hosta can be grown as annuals in pots or in the garden, but that the 'SunHosta' is an exception to the rule and does not need the regular dormant period of other hostas.
So to me this indicates there are two differences in the 'SunHosta' one is direct surn tolerance, and one is the lack of need for the regular dormancy period of other hostas. I blew the one picture up of the 'SunHosta' sitting in pots at Home Depot and I can almost say for sure it says "perennial" on the pot, but can't be 100per cent sure, just can't quite get it really clear.
This plant appears to have been selected to be marketed to the very warm areas of the southeast, where lack of dormancy and sun tolerance would be well received. But, somewhere I did read that this hosta should perform just like any other hotas in the more northern regions. I think I will travel over to the Florida forum and ask over there if they are familiar with the 'SunHosa'.
