Hardy geraniums - the genus name is Geranium. A common name is Cranesbill. Your flower looks like one of these.There are hundreds, probably thousands of varieties.
Tender geraniums are not geraniums at all. The genus name is pelargonium. They are often sold as Zonal Geraniums to distinguish them from true geraniums.
The leaves of hardy geraniums vary a lot, depending on the species / cultivar. Here are some piccies:
Zonal geranium leaves also vary a great deal. Here are some:
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.
Should be easy then. They will send out lots of new growth after flowering. Wait till July and take firm cuttings.
Hmmmm! You may be right, Fidgetbones, though I can see that argument being used by unscrupulous dealers digging up threatened plants all over the world - "These rare crocus bulbs come from Turkey - I know they are not supposed to be dug up but they were growing in a field that was being dug up to build a local hospital and my supplier rescued them so they might find a good home". I just don't think that a prestigious organisation like the RHS should allow it, as it sends out a bad message - it's ok so long as you can explain it - no need to show certification.
I find the montanas and alpinas easy. The others I have mixed results with. It seems to depend on the variety. Last year I failed with clematis Guernsey Cream. This year I have had two that have taken - though over winter they looked dead for all the world, except that the roots coming out the bottom of the pot were yellow, a good sign. Now they are flying away. I have had no luck at all with C x jackmannii, having tried three times. By the time I can get decent cutting material after flowering, there isn't enough time for the cuttings to estamlish before winter,.unlike the early flowerers
I suspect that most lilac cultivars are grafted onto the common syringa vulgaris, so the suckers will not come true. Cuttings are rather tricky - they need regular misting.
I agree wholeheartedly. Its perverse, rather obscene.
Although it is possible (with difficulty) the result is always poor as cuttings don't form leaders and seedlings won't produce plants of the right upright shape.
The seed pods can be attractive to young children. Also don't plant one where seedpods could drop into a fish pond.
Lovely tree. Just remember the seeds are poisonous.
I am pretty sure its a variety of sorbus. Leaves are very like sorbus Joseph Rock but you will know better when the berries ripen.
