Dirr states "In Georgia, Endless SummerT flowers in May-June, with a second
full blown flush in October-November.  Our greenhouse research showed that
when flowers are removed, it takes 10 to 12 weeks before the new shoots
develop full size inflorescences. "

I received a small sample plant of "Endless Summer" last year. It survived
temps below 10 degrees F here, and a prolonged period below 32 . It looked
ok, was beginning to leaf out, and was frozen back to the ground, presumably
because the warm snap reduced its cold-hardiness. It's now got a bud on it.
