Expressed as month (1 or 2 digits) and day (2 digits); Number of days after June 31 when 50% of the individuals in a plot had at least 1 flower; Beginning bloom or the number of days after May 31 when an open flower was found at any node on the main stem. Similar to the trait Reproductive stage (Reprod) and First flower (Fflr). Their definitions are similar but synonomy can not be determined.
