Reported in flower
No records here show flowers yet, so there is no flowering season to show. One needs at least 20 records from 5 different years.
Reported in fruit
Only 2 records here show fruit, too few to show a fruiting season. One needs at least 20 records from 5 different years.
What these results show
These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.
