Reported in flower

Usually reported in flower late June to mid-August, middle week Jul 19–25.

From 94 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

No fruiting season shown here. The weeks are still too uncertain to show a season.

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.
