Zonals usually have thick fleshy leaf stems, quite unlike those of true geraniums. If you see a young zonal geranium seedling with a purple ring around the centre of an otherwise green leaf then it is likley to be one that will produce red flowers. If the leaf is plain light green then the flower is more likely to be white.
I know pelargonium are tender, I just thought the flower on this one I have looked more hardy geranium, but looking at the leaves they actually look more on the 'fleshy' tender side.. I am assuming therefore it's tender, I'll have a look around for hardy geraniums!
hardy geraniums are some of my favourites. Geranium phaeum is very early, been out for some time, very dark purple but also has a pink and a white version. Next there's G sylvaticum and G. macrorrhizum. All good for a shady spot. After that there are hundreds of them, something for any place in the garden
"Roseanne" is the blockbuster Geranium...clever plant breeding has produced a vigourous, longer flowering variety than the usual types many of which are over too soon in the year. Needs a bit more space than most.
Psilostenum is a very striking cerise with a dark eye...stunning.
Anne Folkard has the habit of climbing through it's neighbours and makes a good companion to lavender for example.
Woodgreen boy, you are right. That,s the one I meant! Got mixed up. I got Orion firstAnd Roseanne later. Its roseanne that I haver two of. I also have the other two you mention. Psilostenum is easy to divide. Ann folkard has very similar flower colour but lovely yellow green leaves. Like Roseanne it does not divide easily. I have had mine for 8 years and have not yet seen a separate crown confidently split off.
Loopyloo on the old BBC site once told me she had managed to divide her Roseanne so I wait in hope. What's your experience?
Never done it, Nutcutlet. I goggled some sites one or two recommend it, both stem and root cuttings, including one specifically naming Ann Folkard, which has similar structure to Roseanne, but only if bottom heat is applied to keep the temperature above 22 C.
