Not much of a reference , but a great cover.
I always introduce myself as a "general gardener" since my interest in plants and gardens is so diverse, I grow alpine plants and desert plants, native plants and exotics, plants that need the shade in the under-story of trees and plants that need blazing sun. I also have very different ways of growing plants, some I try to grow in the most natural of habitats and others I grow in containers with a definite artifice trying to match the plant to the container.
But for all this, when reflecting on what seems an unfocused mix, I can see some connections between these disperse collection. This little group of succulents perhaps will illustrate how my various interests come together, they are three different plant families, but are all considered caudiciforms, that is, they all have swollen trunks (and maybe roots) that enable them to store water in extreme dry conditions. They are great subjects for growing in containers and (to my taste) have great and presence and an almost bonsai like character in a well chosen pot. So in this small group of plants I cover several of my interests,those being succulents, vines, euphorbias and my attempts to achieve that Japanese aesthetic of matching plant to pot.
Adenia, I was surprised to find, are in the family Passifloraceae.
My plant is still immature, but already has a spectacular caudex .
Cyphostemma sp.(elephantopus ?)
Cyphostemma are in the family Vitaceae
Jatropa are in the family Euphorbiaceae
