I've been bummed that I can't seem to bring that type of joy indoors, though. When I cut them and put them in water, they start out looking all bright and cheery and within hours they're droopy and downers.
The internet to the rescue! I googled the problem and came across this website explaining why this happens and what to do about it. The short answer? Immediately after cutting, put the stems in boiling water for 30 seconds. This technique even brought mine back to life!
The internet is the best, isn't it?
