What pollinators like

I did a quick tour around the backyard to see which of the flowers are attracting the interest of local pollinators. Eupatorium 'Phantom' (dwarf Joe Pye weed, eupatoire naine) is evidently close enough to our native Eupatoriadelphus maculatus (formerly Eupatorium maculatum) to attract our native bees. (I got this recently at Valumart at 50% off!) Helianthus annuus (sunflower, tournesol) is a reliable bee attractor (unless you get one of the newfangled pollenless varieties, which may be lovely cutflowers but are useless for pollinators and seed-eaters). Echinacea purpurea (purple coneflower, echinacée pourpre), although not quite native here (we're a bit too far north and east), is a favourite of humans as well as pollinators. (Another 50% off deal!) Rudbeckia hirta (black-eyed Susan, rudbeckie dressée) is always abuzz. Finally, mint (Mentha sp., menthe), which grows as a weed in the backyard, is a hive of activity when in bloom.
