This one reliably blooms every year. In theory, it likes a bit of a dry rest over winter, but in practice, I keep watering it as long as leaves are growing.
I’ve had this one for years. It’s a faithful bloomer, although I didn’t get as many flowers this year as I usually do, and it bloomed a bit late, too. Lycastes are deciduous, so I give them a dry winter rest, and start watering again when I see new growth. This one really needs to be potted up to a larger size pot. That may have something to do with why the bloom wasn’t as good as it normally is.
