Kalanchoe daigremontiana

Mother of thousands, Kalanchoe daigremontiana, is described as an annual succulent that will not survive a frost. For years, I kept this native of southwest Madagascar potted and moved it indoors any time we had a freeze warning. Last winter, it got too big for me to carry in and out and I left it outside. Although others in Austin experienced hard freezes, my neighborhood just south of Lady Bird Lake apparently did not. Old stands of mother of thousands bloomed up and down my street.

When taking photos for GBBD last January, I noticed that buds were forming on my potted plant.

It had never bloomed before and I was excited. It took almost six weeks for the flowers to open fully; however, it remained in flower for months. Flowering does not necessarily happen annually. The conditions must have been just right in Austin last winter because I’d never seen it in flower before, mine had never flowered before, but I suddenly saw it flowering everywhere.

My kalanchoe tolerated full sun even in this hot, dry year. It was fairly drought tolerant. I watered it when it looked reddish and sunburnt but I didn’t have to baby it. When it began to rain and cool down, the leaves became greener and plumper. I would say that its growing requirements are similar to Aloe vera. It’s tempting to want to plant both because they are great structural plants that can take Austin’s punishing summers. They’ve survived the warmer than normal winters we’ve had in 2007 and 2008. However, 2009 is supposed to be colder than average–plants which have recently thrived may be in for a killer surprise.

Fortunately this kalanchoe is aptly named mother of thousands. The edges of the leaves are covered with plantlets which drop off and root. I got my start by taking a few leaves and sprinkling the plantlets into the pot containing another plant. Sure enough they sprouted and pretty soon took over the pot. Now they’ve sprouted all around the pot

The stems also flop over and root. I’ve read that the cuttings must be kept dry to root but I haven’t tried that yet because when the rains finally arrived this fall hundreds of little plantlets fell from the leaves and took root around the mother plant and even quite far away wherever the rainwater had washed them.

I’m potting them up to take inside over the winter as a backup in case the mother plants freeze. If you’re an Austin gardener and want some, let me know.
