For the past two growing seasons, I’ve tried to develop an appreciation for plants with black foliage, but it’s not working. Newly bred black plants like ‘Black Scallop’ ajuga, black-brown ‘Australia’ canna and ‘Black Magic’ elephant ears (Colocasia esculenta ‘Black Magic’) are just unappealing to my clearly unsophisticated garden tastes.

Warm, bright days burst open tree and shrub buds, and bring out flowers on many of the spring bulbs. And with the flowers have come clouds of pollinators — bees of several kinds, small and large wasps, various flies and even some butterflies. A lovely mourning cloak (Nymphalis antiopa) was seen floating through the garden, coming to land on the deck in a patch of morning … [Read more...] about Seeking enthusiastic pollinators
