Reported in flower

Usually reported in flower late May to late June, middle week Jun 7–13.

From 130 records that show flowers. Not every photo of a plant in flower is marked as flowering, so this shows when people reported it in flower, not when it flowers.

Reported in fruit

Usually reported in fruit early June to mid-February, middle week Oct 4–10.

From 350 records that show fruit. Not every photo of a plant in fruit is marked as fruiting, so this shows when people reported it in fruit, not when it fruits.

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.
