One of the hardiest and most reliable of perennial plants is the Geranium, not to be mistaken with the frost tender Pelergonium.
One of the best known is (Max Frei), flowers are a rich magenta forming a perfect round clump, described in most catalogues as being about eight inches tall, I find that in our garden the plant reaches a height of six inches.
Max Frei flowers from mid June until early august. It is not a geranium that is hard to find, in fact it could be described as one of the more common varieties, in spite of this if you have not grown it before, give it a try and I am sure like me you will be pleasantly surprised.
