Every year I buy a few bright new mums-- to stick in pots lining the front steps, and so on... and after the season, as they are perennials, and as Tony would say 'they want to LIVE', I try to find places to shoehorn them into spots in the garden. And because it is Northern California, & conditions are good, they all survive & thrive & bloom again the next year.
Today I bought some lavender ones, for a change of pace. And an aster. Why do we have no asters?
