Gardeners' Notes:

Positive bendipa On Mar 26, 2015, bendipa from London
United Kingdom wrote:

This is a good variety of Cranesbill with its conspicuous violet blue flowers and their white eyes. It flowers prolifically from June to October, but you have to cut the stems back after each flush of bloom to encourage the next one.

A word of caution about winter. The plant dies right back to the point that it disappears completely. Where I live there was no sign of life until the end of March, and I thought it had rotted away as I could not even see a crown. So it is deceptive, and even though it's a late starter there is no need to worry about its eventual reappearance..

In the Chicago Botanic Garden's hardy geranium evaluations, this was one of six taxa (out of 111) that received the highest ratings based on heavy flower production, strong plant habits and good health, cultural adaptability and winter hardiness.

The Royal Horticultural Society has granted this cultivar its coveted Award of Garden Merit (AGM).

In Chicago (Z5b), it bloomed from late May to mid-August.

Its habit is its weakest feature: it's upright and leggy, to 24" tall by 38", and tends to sprawl. Cutting back hard after flowering improves appearance and health.

Like all blue-violet hardy geraniums, this one looks best when grown next to plants with colors that complement it, like lemon yellow or strong pink or chartreuse.

It can develop decent red-burgundy fall foliage color.

Tolerates the hot humid summers of the US southeast.

A better performer than 'Johnson's Blue', with a sturdier habit and better foliage.

A hybrid between G. pratense and G. clarkei 'Kashmir Purple', developed at the Cambridge University Botanic Garden and named after a street in Cambridge, England.

I'll say I did not enjoy growing this plant. It's flowers are nice enough, though I didn't feel they made up for the lack of structure the plant had. It might be nice when planted in masses where it could better hold itself up (I only had a clump of three plants) or in an informal garden where it can weave through its companions. I will say when it did weave through the leaves of the hostas or boxwood nearby it did look lovely. It does not spread quickly.

A beautiful plant when not a lot else is blooming except the roses and honeysuckle in my garden in early June.

I have to stake it on both sides (it's a small hedge), so it remains upright and doesn't flop over other plants and hog the sun.

The plant is leggy but I trim back throughout the summer to control this. The flowers are beautiful and bloom all summer long.

Tends to be a bit leggy, but a really pretty Geranium anyway! Plant it where it can drape over a wall, or weave thru other perennials and it is a winner!!!!
