Alstromerias have long been on my "wanted" list. I've tried a couple here and there over the years without much success, but this year found a nice 6" pot of them on a clearance table, and gave it another go. It really didn't look that bad when I purchased it; I was surprised to see it marked down. That was late May or early June, and the plant has shown consistent color since. A few weeks ago I thought it was about to dwindle down and I cleaned off the spent growth. Now it's flowering freely again. It's in a protected spot, so I'm going to mulch it heavily and hope for the best.
Evan, I'm curious how yours have performed this year.
