Seems rather 'criminal' to chop off perfectly good flowers. Course that could be because I never have so many blooming that I could not blink an eye at giving some "the axe".

Disas are beautiful. From what I've read & heard they aren't the easiest of plants to keep. If you happen to have the correct conditions you're in good shape. If you don't they will crash and burn in the blink of an eye.
