Mystery of the non-blooming clivia in the cold climate
I have a potted clivia miniata that's about six years old, purchased from a commerical nursery and grown by me in Seattle since then.
Once, it bloomed, just about five or six blossoms on one stem. Since then, it hasn't bloomed, but continues to sprout new plantlets every year. Right now it's one large parent and five plantlets in an 8" pot.
In the summer it gets about six hours of sun a day, and occasional watering. In the winter I put it in the basement (55 degrees or so) and don't water it.
The foliage is dense and dark green and glossy, and I pull off about two-four dying exterior leaves per year.
No flowers. What can I change?
