Rainy Side Notes

I grew A. 'Black Prince' in front of Bells of Ireland (Moluccella laevis) this year, which really made the deep crimson snapdragon flowers and dark leaves "pop" in front of the light green flowers of Bells of Ireland. As a cut flower, it is outstanding. If wintered over it will begin to flower in May; in my garden, the plants continued flowering through November.

For the vase, cut flowers when about 1/3 of the flowers are open or approximately eight flowers. Flowers persist 5-8 days in water.

All parts of the plant are poisonous; do not ingest! Snapdragons are great bee plants.
