Asters and colchicums

This composition was photographed last autumn. In addition to colchicums and asters there are hardy ageratum, morning glories and sedum. The colchicum is the one sometimes named 'byzantinum album' or 'Innocence'. For our climate it is probably the best large, white-flowered colchcium. The morning glories have been in the garden for so long I forget their source or their name. They self-sow freely. They are very attractive with garden cleome, too.
