Flowers: A Matter of Timing

I'm headed over to AGBT Agriculture tomorrow, after getting to Phoenix ahead of time to check out some sights.  The Desert Botanical Garden is amazing, particularly since it stays open until 10pm and so you can watch the lighting change as the sun sets and then enjoy some artistic artificial lighting on some of the trails.  Before I left, a few daffodils were in bloom back at my home.  So while I have plants on the mind, I'll unleash another plant engineering fantasy but this time with a dose of contemplation whether it would really be a good idea.  What if we could engineer flowers to show up at any time we wanted?
