Cinta, I have Senecio vitalis and from a 4 inch pot I divided the plant to plant into 2 different pots with a bit leftover.
Morning sun is what I give the chalksticks and I water once or twice a week so far for this summer. We've been lucky; our hot temps have only been the 80's to mid 90's for this summer in zone 9b. Mostly the 80's.
Here's planter with Senecio vitalis 'Chalksticks'
Planted April 2013 and now in Aug 2013
