First flowering

Record rowan first flowering when the petals of the first individual flower in the cluster are open sufficiently for you to see inside the flower.

If you have recorded rowan events before, continue to record on the same tree.

Expected Date Range: mid-April to late May 

Available historic data: we have individual records from 1952-1977, and some from 1980-1999
