Pelargonium species

An unknown species from section Polyactium

Another unknown species, this time from section Hoarea, and a real beauty.

Finally, a fabulous silver-leaved form of P. triste.  I have a few plants of this I grew from seed many years ago, but would happily throw them all away if I could get hold of this form.

Jon - it's so very interesting to see species pelargoniums like this; hardly know them at all and the flowers are delicate and beautiful compared with the more blowsy horticultural 'geraniums'. I wonder if anyone is growing the S. African heaths in the same way as they used to be many years ago? Both of these genera would be fascinating to see more of, and I could imagine a few appearing at the Shows every now and again to test the boundaries! There must be a few that come from very similar climates to bulbs that are grown and displayed regularly.

Hi Tim

I'm glad you found this interesting; I think these species make very attractive plants.

Julian and Sarah Sutton of Desirable Plants grow a number of South African Ericas, and usually offer a few each year.

Hi Jon,

We have grown and grow a few geophytic pelargoniums. They survive well in an unheated greenhouse and a couple of species flowered well this year - we almost took one to Summer South show.

I like your unnamed species - very floriferous!

Pelargonum oblongatum (Section Hoarea) looked good this year. For us it loses its leaves before flowering, though I have seen images where leaves are retained.

Hi Martin

Thanks for posting that - another very attractive species.

Yes, these pelargonium are striking.
