Geraniums

Another group of low-maintenance, long-blooming perennials with aromatic foliage. We choose varieties that creep and form new stems to create weed-proof mats in sun or shade.

 

We currently grow: 
Geranium xcantabrigiense 'Biokovo' (Dwarf Geranium)
Geranium macrorrhizum (Bigroot Geranium)
NEW! Geranium maculatum (Wild Geranium) - photos & description coming soon

A suberb sterile hybrid between bigroot geranium (G. macrorrhizum) and Dalmatian cranesbill (G. dalmaticum) made at Cambridge University way back in 1974. Chosen as the 2015 Perennial Plant of the Year thanks to its longevity and low maintenance. Handsome dissected, semi-evergreen and aromatic foliage combine with masses of beautiful white flowers with pink stamens are borne May through July and sporadically into fall. Underground stolons creep and send up new shoots to form a weed-proof mat in two to three seasons. Works beautifully under small trees, in rock gardens, along paths, helps to hold soil on modest slopes, as a spring bulb cover and combines well with many perennials since its not aggressive. Does not produce seedlings. 

 

Recommendations for growing Geraniums

Geraniums are adaptable to a range of soils and conditions, except very wet soils. Removal of perennial and rhizomatous weeds is essential before planting. Loosen compacted soils and blend in a moderate amount of compost before planting. Plant at soil surface and mulch 1-2". Water well in first year of establishment. Flowering shoots will eventually grow out of the soil and can be cut back close to the ground after flowering to thicken and renew the planting. Does not need regular division and has no major pests or diseases. Full sun keeps plants shorter; shade produces less flowers.

Also called cranesbill, hardy geranium

Height         12 inches (30 cm)

Spread        18-24 inches (45-60 cm) 

Flower         Magenta-pink

Blooms        Late spring to summer

Fall colour    Foliage turns copper

Hardiness    Zones 2-8

Light           Full sun to part shade

Moisture      Average to dry

Soil             Adaptable

 

A larger, tougher geranium than 'Biokovo' to cover more challenging areas. Large sticky, dissected leaves are strongly aromatic when brushed, and bright magenta-pink flowers in summer make a vibrant combination. Foliage height is about 12 inches (30 cm) but flowers can stand another 6-8 inches (15-20 cm) above that. Thick fleshy roots smother weeds and can tolerate summer heat and humidity. Great geranium for dry shade, blending hardscape corners, spilling over rocks, in xeriscape designs and amongst large evergreen perennials and shrubs.

 

Recommendations for growing Geraniums

Although this geranium is as adaptable as 'Biokovo', it prefers well-drained sites and can rot in consistently wet soil. Removal of perennial and rhizomatous weeds is essential before planting. Loosen compacted soils and blend in a moderate amount of compost before planting. Can be planted slightly below the soil surface and mulched 1-2". Water during dry spells in first year of establishment. Flowering shoots will eventually grow out of the soil and can be cut back close to the ground after flowering to thicken and renew the planting. Does not need regular division and has no major pests or diseases.
