I love the Dr. Seuss quality it adds to our backyard. I typically prune my plants to discourage legginess, but with this one I did just the opposite. I wanted it to get as tall as possible.
There are many Aeoniums to choose from, but if you’re looking for large ones, Aeonium undulatum, Aeonium ‘Cyclops’ and Aeonium ‘Voodoo’ are good picks.
If you live in San Francisco, Flora Grubb is a good source for Aeoniums.
