Crinums are wonderful plants for warm-climate gardeners. Blooming in late summer, graceful flowers on tall stems fill the air with a honey-like scent.
Looking very much like the amaryllis to which they are related, crinums grow from sturdy bulbs and have wide, strap-like leaves. They will not refuse a good garden soil but will grow just as easily in junkyards, if that is where you happen to garden. Like your friend who refuses to pick a restaurant for dinner, crinums are indifferent to their surroundings: sun, shade, wet, dry–oh, whatever. Just plant them up to their necks someplace and leave them alone. The only thing they fuss about is cold–they’re not reliably hardy north of Zone 7. But mine came through the polar vortex without complaint.
I never feed them. Sometimes they get mulched with shredded leaves if I need to empty my shredder bag nearby. Pinching off the spent blossoms keeps them going.
If you insist on moving one, be sure to get as much soil around the bulb as possible and don’t sever the bulb. Understand before you attempt this extraction that bulbs can grow to be absolutely enormous, basketball size (29 inches or 75 cm in circumference) or larger. Brush soil off the top of the bulb until you can discern its width, give it five inches on either side, and dig straight down. But really, if you’re the uncertain type, better plant it in a nice, large container, and move the container instead.
