Thanksgiving and Christmas cactuses – what you need to know

A close inspection reveals not just Christmas but Thanksgiving cactuses. Both members of this seasonal gang are epiphytes, high-elevation jungle species that get most of their nutrients from the air and rain and live in trees like Tarzan. Cactuses yes, desert no.
Thanksgiving and Christmas cactuses, members of the Schlumbergera genus, have glorious backswept petaled flowers that appear between October and February, then again in spring.
They’re easy to grow, pretty much no-kill houseplants that are likely to outlive their cultivators. My neighbors the Laphams are tending a plant that came from his grandmother, and Jody Lapham is older than I am, which is old enough to have grandchildren.
Whether you buy Thanksgiving or Christmas cactus isn’t important, but if you’re a stickler for detail, look closely at the plant’s flattened stems. If it has sharp, hooklike edges, it’s a Thanksgiving cactus; if the edges are rounded, like my neighbor Jody Lapham’s is, it’s a Christmas cactus.
Both flower in May in their native Brazil — flor de maio, or May flower — nowhere near the holidays for which we’ve named them. Funny things, common names.
