Geranium cantabrigiense ‘Biokovo’, the 2015 Perennial Plant of the Year, fills all the criteria for this award: multiple seasons of interest, widespread growing range and availability, low needs and freedom from pest or disease problems. In late spring, plants are covered with pale pink flowers that flaunt darker pink stamens. The flower coverage is so great that you almost don’t see the attractive, deeply lobed foliage that will become reddish in the fall.Although this naturally occurring geranium hybrid, hardy in zones 4-8, is European, it does not seed. It is rhizomatous (has underground stems) and thus makes an excellent groundcover. The rhizones are easy to pull if ‘Biokovo’ spreads further than you wish. The foliage is only two inches high and the flowers hover just above the leaves. They stay in bloom for about a month.This hardy geranium only needs good drainage, no fertilizer, and a moderate amount of water; it is, in fact, somewhat drought tolerant once established.I’ve been growing ‘Biokovo’ in my east-facing bed for years where it only receives morning sun but it can be grown in full sun as well. I grow its cousin ‘Biokovo Karmina’, a magenta pink’, in oneof my south facing beds. My Geranium cantabrigiense ‘Biokovo’ grows in the shade of an ancient crabapple with Allium pulchellum, Hosta grandiflora, Hosta ‘Frances Williams’, Astrantia major, and Convallaria majalis ‘Variegata’, all perennials that are perfectly happy in relatively dry shade.On the other hand, in full sun, I’ve combined ‘Biokovo Karmina’ with Rosa Oso Easy ‘Cherry Pie’, Heuchera ‘Georgia Peach’ and ‘Berry Smoothie’.I’m sure you can find a place in your landscape for one of these geraniums.
