The plant stall is now OPEN!.
This is a plant for full sun and very well drained poor gravelly soil. It has white flowers on fairly tall stems, I've grown them from seedlings harvested from my garden so hopefully I've learnt to pick out the ones which are white! Each plant is itself short lived, maybe 2 years, but it should self seed freely if you don't dead head it, particularly into gravel, so you can keep it going in your garden. Sold in a 1 litre square pot.
