This wonderful Melianthus, with extra jagged leaves and red flushed stems, came as a seed from Maurizio Usai of La Pietra Rossa garden in Sardinia.
It seems to have a more fastigiate shape and has made a handsome plant this year.
Erigeron annuus grows to about 5' and has nice modest white daisies for weeks and weeks. It is a short lived perennial but seeds gently.
