Echeveria nodulosa (Baker) Ed.Otto is the correct and accepted scientific name for this species of Echeveria. It was named and described as such by Carlos Frederico Eduardo Otto in Hamburger Garten- und Blumenzeitung in 1873. It was first named Cotyledon nodulosa by John Gilbert Baker in Refugium Botanicum in 1869.
MANY websites and databases, actually MOST OF THEM, say the scientific name is Echeveria nodulosa (Baker) Otto. As you can see, the author’s name is different… Otto is the abbreviation for Christoph Friedrich Otto (1783-1856). Christoph Friedrich Otto is the father of Carlos Frederico Eduardo Otto (1812-1885). The father died before the species was named and described in 1873 so it is doubtful he named the plant…
There are a few cases where a botanist had unpublished books where he named a few new plants. The publications were published after their death and they still received credit for naming the plants. I don’t believe that is the case here. Someone just made an error and others followed.
I bought my Echeveria nodulosa from Mast’s Greenhouse in the spring of 2016. It was really neat and I never had an Echeveria quite like this one. I was doing some experimenting with succulents in one of my beds, so I put this Echeveria in the ground, pot and all, in the bed behind the foundation of my grandparent’s old house. I know that sounds weird, but the plant will have to be brought inside for the winter and it is easier to just pull out the pot if it doesn’t work out in that spot. This may have been OK except for one thing… The Marigold ‘Brocade’ decided to take over while I got busy with other things. I basically forgot about the two Echeveria I had put in the bed and when I remembered, the bugs had all but destroyed them. You would think the smell of the Marigolds would have deterred the bugs. Anyway, I took the pots up and put them on the plant tables with the other succulents. When cooler temps came, I took the potted plants inside. Unfortunately, my Echeveria nodulosa never fully recovered and didn’t make it through the winter.
Origin: Central and southwest Mexico
Zones: USDA zones 9b-11b (25-50° F)
Size: 12-24” tall x 24-36” wide
Light: Sun to part shade. Echeveria need bright light if inside or they will stretch.
Soil: Fast-draining. Good quality potting soil amended with pumice (50/50) or additional perlite and chicken grit (2-1-1).
Water: Average during the growing period, sparse in winter.
Propagation: Leaf and stem cuttings.
I am definitely not an Echeveria expert but I do know they have the same basic requirements as most cactus and succulents. They need bright if inside and will stretch over the winter if watered too often and not in bright enough light. I have not grown any Echeveria for several years because I really didn’t have adequate conditions while inside over the winter. I have better now so I may try again…
Hopefully, someday I will find another Echeveria nodulosa to bring home and try again. If you have any comments, questions, or suggestions, I would like to hear from you. Hopefully, some of the links below will be of greater benefit to you. There is not much online about this species.
