Flowering calendar

Which plants flower in each month, and where the gaps in the year are — because a fourth June plant helps far less than a first February one.

The year, month by month

What this cannot tell you

Dates are northern-hemisphere temperate. Southern-hemisphere readers can shift roughly six months, but that is an approximation rather than a translation — flowering responds to day length and rainfall patterns that do not mirror across the equator.
Flowering dates are northern-hemisphere temperate defaults. Records carry a hemisphere, and southern-hemisphere readers should shift roughly six months — but that shift is an approximation, not a translation.
Local timing varies by weeks with latitude, altitude, aspect and season, and blossom dates have been moving earlier.
It shows the plants in the catalogue, not everything worth planting.
Flowering is not the same as yielding. Nectar secretion depends on weather and soil, so a plant can be in full bloom and offering very little.
