The famous giant cactus of the Southwest. I grew it from seed just for fun – although it can take a bit of frost, it stands no chance in our garden, both because of the freezing and because of the winter wet. But my seedlings are still alive after a year and a half – and still tiny. Let's see how long I can keep them going.

We're re-establishing this plant this year (it used to grow in our garden, but slipped away)

Seed for this plant is included on my seed trade list
