The best plants for bees this time of year (Late-Summer and Fall) would be the following three varieties of flowers:
Asters (Symphotrichum spp., perennial): The pinks, blues and purples of late-summer and fall aster flowers are a delight to all bees. There are so many wonderful varieties to choose from it’s hard to know where to start. The classic ‘October Skies’ (image left, Symphyotrichum oblongifolium ‘October Skies’) is a wonderful late bloomer with lavender-blue flowers and orange centers, and the dusty sky blue ‘Bluebird’ (Symphyotrichum laeve ‘Bluebird’) is an earlier bloomer with prolific flowers.
Eupatorium purpureum 2Joe-Pye Weeds (Eutrochium spp., perennial): This group of mid-to late-summer bloomers produces big, fuzzy heads of purplish-red flowers filled with nectar and pollen. Native across North America, many of the sun-loving perennials are adapted to moist ground. One of the finest garden varieties is Eutrochium purpureum ‘Little Red’ with its 4′ tall stature and pretty reddish-purple flowers.
Goldenrods (Solidago spp., perennial): Lauded as one of the best bee flowers for late summer and fall, goldenrods become a buzzing mass when they open. In fact, goldenrod honey is a delicacy, known to be darker with a distinctive bite. Excellent garden-worthy goldenrods include the dwarf forms ‘Golden Fleece’ (Solidago sphacelata ‘Golden Fleece’) and ‘Baby Gold’ (Solidago ‘Baby Gold’).
