Does anyone know how I can get hold of seed or an aloe suzannae in South Africa. I've been looking all over but just can't find an aloe suzannae or someone who can help me getting one. My email address is [email protected] please if anyone can help me.

I have grown A. susanne for 18 years. During that time one plant has flowered twice in late winter or early spring. Both years it flowered following very wet winters for S. Calif. 30+ inches. this plant is over 40 years old. I have no idea how much older than that it might be. I acquired the plant from the late Dave Grigsby who flowered it several times at his Vista nursery, he had owned the plant for 20+ years.

The largest of the 2 plants we have has branched at the base. '

It is a very versatile plant, but should not be watered much in our summer and should have very good drainage.

This is one of the larger Aloes that are user-friendly (nothing sharp or dangerous). It is a relatively rare species that has recently become much more available in cultivation.

It eventually develops a stem and becomes a tree aloe, though there aren't too many stemmed examples in So Cal (slow grower). Very old plants in Madagascar eventually branch as well and I have seen photos of plants with a huge massive set of branches and reaching up to about 15' or more. Seriously doubt that sight will be one seen here in So Cal for many many years.

Flowering is a rare event in this species with only maturing plants flo... read more
