Sherri, I think that's probably right. I give mine a shot of fert in the spring, let them grow lots of new leaves to replace the ones the caterpillers ate, then no more all year. Once they've eaten up all the fert, that's when the flowers start. Late spring.

This purple-flowered one is particularly cold-tender, so unless you have a BIG greenhouse, you probably don't want to try it. It only survives in my garden because it cowers under a huge stand of bamboo.
