My last niveum finally faded out at 5 months and 4 days. At the 4.5 month mark it had a few tiny brown spots, which increased steadily for the next couple weeks until it abruptly browned and crumpled. I avoid feeding plants in bloom but I did decide to feed after 3 months of open bloom, as the plant was looking needy. I wonder if it would have lasted longer, or less long, had I not fed?
Second bud has opened up. Also had a nice surprise when I had it out to water, 2 more spikes! One with two buds, and the third still in low sheath. It must love this hot summer weather we've been having. Looks like I'll be getting a few more months to enjoy it!
