Question
Hi Will,

This afternoon I was gifted with a tiny bare root Mexican Hat plant cutting by a generous florist who wasn't able to offer care information or a botanical name (but she thought that whatever care I provide will be better than what it has been getting!) Knowing how difficult it is sometimes to identify plants by common names, I don't expect miracles, especially since I can't even offer a description beyond that the cutting has a single tiny 1/4" leaf and a few fine hair roots, but any information you can provide about this particular plant is appreciated.

Thanks,
Alexandra

Hi Alexandra,

From your very brief description, I suspect your plant is a Bryophyllum daigremontianum (sometimes listed as Kalanchoe daigremontianum). There is a very different plant (Ratibida) sometimes called Mexican Hat plant, but I don't think that is what you have. If I am wrong, please email a photo to my address listed below so I can properly ID your plant.

Mexican Hat is more commonly called Mother of Thousands, so named because of its unusual production of tiny baby plants all along the edges of its leaves. These baby plants drop to the soil below and easily take root on the surface of the soil. I believe that is what you have. For now keep the surface of the potting soil just slightly damp

It does best in a sunny south-facing window, although it will survive in bright indirect light. It is a succulent and prefers to stay on the dry side. After it has developed into a mature plant, allow the top half of the soil to dry out before watering thoroughly. In winter, keep it even drier and try to keep temps in the 50 to 60 degree range. It does fine in low humidity. Fertilize very sparingly at half strength and only when it is growing vigorously.

This plant will grow quite tall and gangly if it is not pinched or prune back periodically. It tends to drop off its older leaves, as it grows taller. In time it will bend over as the stems become too tall to support themselves. Pruning will help promote branching. It sometimes flowers if it gets lots of bright light, is kept potbound, and has long days and short nights. It is a nearly pest-free plant.

Please let me know if any of this is unclear or if you have any additional questions. If you would like to e-mail me some photos, I may be able to provide some additional insights.
