The first blooms opened on the Scotch broom (Cytisus scoparius) called "Moonglow" today, which seems very early. As is so often the case, only one or two buds have opened--well ahead of the main rush of flowers, but I record today as the first day. This plant bloomed last year on March 24, so these are quite early. A year according to this plant was 343 days, one of the shorter years the plants have so far calculated. The median has been around 362 days.
First blooms today also on Prunus tomentosa, or Nanking cherry, a small bush cherry.
