This is the third year to grow Lachanalia, and they started shooting new leaves.  I mixed DG (local decomposed granite), course sand and small amount of compost.
The weather here in Southern California must be perfect for them.  Very low maintenance.  I did not give or forgot water during hot and dry summer last year, but they came back.

I have done no horticultural training, just a gardener from a young age.  And get a feel of what agrees with them and what doesn't.   Great to know your info on this.
