Caudiciforms and pachycaul trees are my plant passion.
I love the small Euphorbia caudex forming plants. But I enjoy growing most anything with a caudex. The pachycauls I have at this time are Bursera and Commiphoras. I don't keep them as small as some people do.
A lot of these two groups of plants can be slow in growing a magnificent fat body. But large specimens can be very pricy
. So I generally start with young plants
. That way I can purchase more during the year. But I do drool over many out of my price range.
