Geissorhiza aspera is found on mostly sandy soils, flats, and slopes in the western Cape. It has blue to violet flowers that appear in spring. The first photo was taken by Bill Dijk, the second by Cameron McMaster at Hermanus, and the third by Mary Sue Ittner at Darling.

Photographs 1 and 2 by M.Gastil-Buhl show seed acquired from Silverhill Seeds on a 1 mm grid before and after germination and in photo 3 germinated seeds from BX 317 #17 donated by Nhu Nguyen. Seed was germinated in 3 months on damp filter papers in a closed dish at warm day and cold night temperatures (approximately 60-75 °F day and 35-45 °F night). The resulting seedling in photo 4 has several leaves in its second year of growth. Photo 5 shows it blooming in March.

Geissorhiza bolusii grows on damp shady, sandstone slopes in moss in the western Cape. It grows from 3 to 10 cm. and has small white flowers in a two to eight flowered spike. Leaves are lanceolate to ovate with the lower ones usually prostrate. This species blooms October to January. Photos from Andrew Harvie taken near Bainskloof.

Geissorhiza brehmii is closely related to G. imbricata. G. brehmii , a species of the southwest Cape, grows in wetter habitats, often in standing water or sites wet in winter. Flowers are white to cream and leaves are terete and inflated or somewhat succulent. It flowers in spring. Photos by Mary Sue Ittner.

Geissorhiza confusa is found on rocky sandstone slopes in fynbos in the northwest and southwest Cape where it flowers in spring, especially after a fire. It has cream to white flowers with darker veins. Photos by Jana Ulmer of a single surviving plant grown from seed blooming May 2004 in Northern California and a photo of the corm (on a 1 cm. square grid) by Mary Sue Ittner

Geissorhiza corrugata is found on shale slopes southwest of Calvinia. It has bright yellow flowers and spirally twisted leaves. Photo 1 taken in habitat by Rod Saunders.

The photos below were taken by Nhu Nguyen of plants in cultivation. The leaves display various degree of spiral. When the plants first break dormancy, it is important that they get bright and constant sun in order for the leaves to be at their most spiral. This species is very impressive and each year produces an even better display.

Geissorhiza darlingensis is quite rare in the wild found only in Tinie Versfeld Wildflower Reserve in Darling. It needs to be hand-pollinated to set seed and only opens fully on hot still days. The first photo was taken by Sheila Burrow and the next three by Mary Sue Ittner of flowers in bud and only partially opening. She finds this species to be challenging to grow and was thrilled finally to have one bloom after several attempts growing it from seed. The final two pictures were taken by Alan Horstmann and Andrew Harvie in habitat.

Geissorhiza eurystigma grows in sandy soils near the coast in the southwest Cape. It has deep blue-violet flowers with a bright red center and cupped tepals. The first picture is from Alan Horstmann. And the second picture of one of Alan’s flowers was taken by Bob Rutemoeller

Geissorhiza exscapa , syn. Engysiphon exscapus, has large cream to ivory flowers with a long slender tube and projecting anthers. It flowers September to October and is found on sandy flats and slopes, mainly along the northwest and southwest coast. This picture taken by Roy Herold in the hills above Muizenburg, south of Cape Town, in October 2002 is most likely this species.

Geissorhiza foliosa is found on clay slopes and flats in renosterveld in the southern Cape. A short plant to 20 cm tall with branching stems and short lanceolate leaves, this species blooms September to November. Flowers are lilac to purple. Photos from Andrew Harvie taken near the Tradouws Pass in the Overberg.

Photos by Mary Sue Ittner of plants blooming in mass in a wet area near Tulbagh August 2006 where it was being pollinated by monkey beetles that were almost as large as the flowers.
