Biokovo Cranesbill
Biokovo Cranesbill
An Award-Winning Groundcover for Sun or Shade
Biokovo Cranesbill (Geranium × cantabrigiense 'Biokovo') is a Perennial Plant of the Year winner beloved for its effortless beauty. Delicate white flowers blushed with soft pink cover the glossy, aromatic foliage in early summer, and the leaves blaze brilliant red in fall before holding through winter. Low, dense, and tough, it carpets edges, slopes, and beds in sun or part shade — a deer-resistant favorite for gardens in Edina, Woodbury, and Eden Prairie.

Landscape Uses
Low groundcover and edging: Forms a tidy, weed-suppressing carpet in sun or shade. Space 16–18 inches apart for full coverage.
Deer-resistant slopes and beds: Aromatic leaves keep browsers away while the spreading mat holds soil and adds fall color. Pair with hostas, catmint, and ornamental grasses.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall (late August–mid September). Water through the first season; it grows tougher and more drought-tolerant each year.
How to Plant Biokovo Cranesbill
Dig a hole twice the pot's width at the same depth, loosening clay and mixing in compost. Set the crown level, backfill, water well, and mulch 2 inches deep. Space 16–18 inches apart.
Watering Biokovo Cranesbill
First year: Water every 2–3 days at first, then weekly. Stop 2–3 weeks before the ground freezes.
After year one: Drought-tolerant — water only during extended dry spells.
Q: Sun or shade?
Both — Biokovo flowers well in full sun and tolerates part shade, making it one of the most versatile groundcovers available.
Q: Is it deer-resistant?
Yes — the aromatic foliage is strongly disliked by deer and rabbits.
Q: Will it survive a Minnesota winter?
Yes — hardy to zone 4, semi-evergreen, no winter protection needed.
Q: How fast does it spread?
Steadily but not aggressively — it fills in over two seasons and is easy to keep in bounds.
