It's 2011 but I planted my 6 plants back in 2008 from Van Dycks and they have been going strong ever since... they have a few buds on them now and it's only May 28th but expecting tons more here soon..A cloud of purple floating everywhere. The best I can described them is the flowers come out on runners and seem to float..Mine grow over everything but by the time they are done blooming I can trim those flower runners down to the base of the fern like leaves and the other plants take over. I have gotten second blooms on this plant but can't remember when that occurs.. I have come across small ones in the garden and have given them away and moved them to other parts of my yard last year.. I am curious to see how they turn out, true to parent because it was an offshoot or was it a seed and not gonna look anything like the original.. Check my photos to see how tall mine get..

This is one of the finest geraniums in our climate. Attractive in or out of bloom, but truly magnificent when the flowers put on their show. It is, however, sterile, so perhaps the people who commented about it seeding are thinking of a different plant. In any case, it's worth seeking this one out, because it's a beauty and very low-maintenance.

This geranium grows wild here. In the ditches, meadows and yards. This one does self seed here and comes true. I live on the Kenai Peninsula in Alaska.

My start of this plant came from a friend and without a name. Now I have several large plants that seem to look good with everything and makes a nice way of tieing the whole yard together color wise. It reseeds but is not a problem.

Probably a cross between Geranium ibericum ssp. ibericum and Geranium platypetalum. It is the mostly grown geranium in private and public gardens in Netherlands. It is only flowering once but it does this very abundant. G. x magnificum is sterile and cannot be propagataded by seeds...only by dividing the rootball (rootcuttings). This geranium is often mislabeled (so wrongly sold) as G. 'Johnson's Blue' ...
