Geranuim Blue Blood

StevedaylillyStevedaylilly Posts: 1,087
Has anybody had any experience on this particular Geranium. Someone I know planted 6 of them plants last autumn and I was wondering what the general flowering period is and do they perform well in shade like most hardy geraniums.
I have checked on line and the flowering period seems to be based on the light aspect for the plant. That is if its in more shade than sun, the flowering period could be reduced 
if anybody does have this plant then please advise.

With thanks

    I definitely haven’t, but if yours takes off and spreads, i’d love a piece of root. Postage returned of course.🙂

    Hi Steve, l don't have Blue Blood but do grow its slightly paler relation geranium magnificum Rosemoor. It's a lovely rich colour and has an attractive flower. It does have a short early flowering season, late May into June. It does not rebloom after cutting back like some hardy geranium cultivars. It likes a sunny spot and will need regular division as it goes bare in the centre. Hope this helps a little.

    I was just checking this Geranium, and it's a Magnificum which tends to flower early and finishes the main flush by mid-summer. You can cut these back straight away and fresh growth would usually encourage a second but more sporadic flush into early Autumn. They can cope in some shade but best in sun. The leaves can turn orange in Autumn too.

    Thank you all for your comments 

    Hi Lilysilly. I believe that Blue Blood is a propagation of Rosemoor so it should have similar traits 

    Hi Boarderline. That was actually my train of thought that any Geraniums I have,  I cut back after flowering to encourage repeat flowering in mid summer. Johnston Blue seems to need that cut to invigorate it 

    Hi Lyn - no problem, my friend has 6 of these plants and they are a small variety of Geranuim and have one of the strongest blue flowers. I think they grow about 40cm heights and spread and are well behaved based of other geraniums that do tend to want to move across your boarder to make friends with other plants 

    Happy gardening

    Sounds just perfect, I can do with all the spreading I can get. Be happy to swap with some of mine.
