Pelargonium radiatum A tuberous plant from the South West Cape area of South Africa, on the Dutoitskloof and Slanghoek mountains and on Jonaskop in the Riviersonderend Mountains, on sandstone. The flowers may be pink, yellow or cream, with wine red feathering on the upper two. Flowering takes place between October and January. The name refers to the way the leaves radiate out from the tuber. (Section Hoarea, Incrassatum Group). Photos David Victor.
Pelargonium rapaceum The widest South African distribution of all those species in Section Hoarea, from the Richtersveld, along the West coast on the coastal plain and then along the south coast as far as Grahamstown, on fynbos, renosterveld and marginal strandveld. The flowers are unmistakable, with their pea shape and can be white, cream, yellow, or pink, with wine red feathering on the knees of the upper two. Flowering takes place from October to February. The name refers to the turnip shaped, thickened tuber. (Section Hoarea, Rapaceum Group). Photos David Victor.
Pelargonium schizopetalum A tuberous species from the Cape Province of South Africa. The flowers may be pink or white and are highly fimbriate and on stems up to a foot high. (Section Polyactium). Photos David Victor.
Pelargonium sidoides I don't think this one is geophytic. (Note: This one has thickened underground stems.) But it came up during a discussion about geophytic Pelargoniums. Someone said it was one of the few flowers that was very close to a true black. Rachel Saunders said they had seeds of the black version of it, so I ordered some and now have these nice plants. Andrew Wilson said to be sure to get wild-collected seed since the version of this sold in nurseries was a hybrid and is merely a dark maroon. Since it started getting hot, the flowers don't look as black as they do in the springtime. Photo taken July 2003 by Lee Poulsen.
I ordered this (hoping for a black flower) and when the plant arrived I realized I have it growing all over my garden, in two different colors. It's an easy plant. Photos taken October 2004 by Susan Hayek.
Pelargonium species aff. aestivale (description as for P. aestivale) This tuberous species comes from the Great Karoo, in the summer rainfall area, from Carnarvon to Middelburg. It grows in karroid vegetation on rocky hillsides and on flat areas. Flowers may be cream or yellow, upper two with wine red markings. It flowers from September to December. The name refers to the summer rainfall aspect. Comments as to whether the plant is correctly named would be welcomed by David Victor. (Section Hoarea, Fissifolium Group). Photos David Victor.
Pelargonium species aff. reflexum (description as for P. reflexum) This tuberous species comes from the western side of South Africa, from the Bokkeveld escarpment around Nieuwoudtville. It occurs in fynbos on sandy flats or rocky areas. The flowers are white, the upper two having wine red feathering. Flowering takes place from December to January. The name refers to the fact that many parts of the plant are reflexed, including petals, stigma and posterior stamen. (Section Hoarea, Pinnatum Group). Photos David Victor.
Pelargonium species This is a plant grown from seed obtained from Silverhill seeds as P. incrassatum. Whilst it is clearly a plant of Section Hoarea, it is not P. incrassatum, but I have not yet identified it. Photos David Victor.
Pelargonium species nova This is a recently discovered tuberous species that comes from the Western side of South Africa, in the foothills of the Nardouwsberg North of Clanwilliam. It grows under the shelter of clumps of Restionaceae. The flowers are white, with a small red v on the upper two. They are on long stems to allow the flowers to appear above local vegetation. Flowering takes place during February and March. (Section Hoarea). Photos David Victor.
