[sillystuff]

I have them in my garden. The do great on the California central coast (with only water from natural rainfall except drought years).

Someone else commented that the claim of having to harvest in early morning is silly-- can confirm; just pick them whenever is convenient, but the flowers do only last a couple/few days. Also, no need to harvest the entire flower, just pull the stigmas with your fingers (it isn't difficult, just time consuming).
