Sedum flower.

The best habitats for bees have flowering plants rich in nectar and pollen throughout the growing season. Survey your yard and garden to see when flowers are abundant and when they are scarce. You can then add pollinator-attractive perennials, shrubs and trees to your garden that bloom at times to fill in the gaps and create a continuous flow of nectar and pollen from early spring through late fall.

In the chart on the next page, bloom time is shown in gray for flowers that are attractive to bees. The type of plant (annual, perennial, bulb or shrub) is indicated following the scientific name. Plant names appearing in bold print are super-attractive to bees.

Planting for a succession of flowers. Bloom time indicated in gray/with an “X”.
