Garden Bloom Calendar.
When does each garden favourite actually flower? Here is a month-by-month timeline for popular bulbs, perennials and annuals, so you can plan a border that has something in bloom from the first snowdrop to the last chrysanthemum.
Winter Spring Summer Autumn
Bloom times are typical for a temperate Northern-Hemisphere garden and shift by a few weeks with your climate, the season and the cultivar - a cold spring pushes everything back, a warm one pulls it forward. Treat this as a planning guide, then check the individual plant profiles for the detail.
Building a border? Pair this with the seed-starting chart and the frost & sowing calendar to time your planting, or browse everything by light and water in the Plant Finder.
