Each year members of the Perennial Plant Association choose an outstanding perennial to be their "Perennial Plant of the Year". This year, Geranium cantabrigiense 'Biokovo' has been given this honor.
An easy to grow beauty, this wonderful geranium has white flowers and attractive aromatic foliage which is evergreen in most zones. 'Biokovo' is a strong performer in the garden and makes a colorful, deer resistant ground cover for the front of the sunny border.
Geranium 'Biokovo' forms an attractive mound of deeply cut green leaves topped with a profusion of the 2½" dainty, white flowers with contrasting bright pink stamens. It begins blooming in the late spring and continues flowering virtually nonstop through the summer.
'Biokovo' remains attractive through all seasons. It forms a dense, low-growing ground cover 6"-10" tall that crowds out weeds. In spring and summer, the bright flowers rise above the shiny green aromatic foliage. The beauty of this plant doesn't stop at the end of the blooming period.
As the temperatures begin to drop in the early fall, the foliage begins to transform into brilliant shades of red. In all but the coldest parts of its range, the colorful foliage remains on the plant through the winter. To keep it looking its best in the next season, it is recommended to prune the old foliage in the spring before new growth begins.
Geranium 'Biokovo' is hardy in USDA Zones 4-8. It thrives in full sun to part shade and average, well-drained soil. In hotter climates, it prefers some afternoon shade to perform and look its best. Once established Geranium 'Biokovo' is drought and heat tolerant. As if it needs any other bonus points, it is also relatively disease and pest resistant. Even the deer leave it alone!
Geranium 'Biokovo' is a wonderful companion plant for early season bloomers as well as later flowering perennials. They are striking in combination with the summer blooming Leucanthemum 'Becky' or 'Snowcap'. Other beautiful garden companions are Salvia nemorosa 'May Night', Rudbeckia 'Goldsturm', the colorful summer blooming Phlox paniculata, and of course André's favorite, the daylily. For late season color, combine with ornamental grasses such as Imperata, Muhlenbergia, Pennisetum, or Miscanthus.
