From Mandirola on Monday 4th of December 2023 06:57:06 PM PST
Mandirola ichthyostoma is the most common species of the genus in cultivation. The species epithet translates to "fish's mouth". It prefers to grow in moist conditions, and some people grow the plants with part of the root system submerged in a tray of water. It produces tiny little scaly rhizomes. The photos below were taken by Nhu Nguyen of plants grown by a member of the San Francisco Gesneriad society.

From Dahlia on Saturday 2nd of December 2023 06:14:06 PM PST
Dahlia aff. campanulata is native to Oxaca, Mexico and was described in 2003. The species is distinguished by the exceptionally large, elegant, pendulous and campanulate flowers that are white to light pink with a darker center. Leaf bases have petioles that clasp around the deeply sculpted stem. The tubers are enormous and can grow to 0.5 m (1.5 ft). Plants are also large, reaching 2.5 m (8 ft). The photo below was taken by Nhu Nguyen at the UC Botanical Garden of a plant that matches the description of the species, except that the stems are smooth and not sculpted. Regardless, it is a beautiful species with large pendant flowers and should be planted in many gardens.

From Cyrtanthus Species One on Tuesday 28th of November 2023 04:30:20 PM PST
Cyrtanthus breviflorus Harv. is found in marshy, grassy places up to 3000 m from the Eastern Cape to Kenya. It has bright yellow flowers and flowers mainly in spring and summer, but sporadic blooms may appear throughout the season. It is part of the fire lily group and would normally need fire to stimulate flowering, but Greg Pettit has managed to get a clone from the swamps that thrives in water, and produces up to 14 canary yellow flowers per plant. The first two photos were taken by Mary Sue Ittner at Naude's Nek in the Eastern Cape showing a plant with leaves, flowers, and seed pods. The next three photos were taken by Cameron McMaster, including one showing locusts on the seed pods

This first photo taken by Bob Rutemoeller shows plants blooming in Harry Hay's gardens in May 2004. The second photo below is of a very floriferous form with semi-terete, succulent leaves - a real beauty! It grows (in profusion) on a hillside near the city of Pietermaritzburg, KwaZulu-Natal. Photo (excuse the distracting background!) by Rogan Roth. The last photo from Byron Amerson is an image of 2 month old seedlings sown from seeds purchased from Silverhill Seeds.
