From Crossyne on Wednesday 18th of March 2026 07:41:20 PM PDT
Crossyne flava (W.F.Barker ex Snijman) D.Müll.-Doblies & U.Müll.-Doblies, syn. Boophone flava W.F.Barker ex Snijman, has strap-shaped leaves fringed with long, white or straw-colored bristles, with small, angular, red speckles beneath. It can have as many as 200 small pale yellow flowers radiating on pale lemon to pink pedicels. It is found on shale flats and rocky slopes in the northwest Cape. It blooms in the fall, before the leaves appear. Height: 50 cm. The first photo by Bill Dijk shows the leaves of a plant in cultivation and the next photo from Mary Sue Ittner shows the leaves on plants growing near Nieuwoudtville. Illustrated in the third and fourth photos by Bill Dijk, the flowers are small but many in the flowerhead, with tepals much recurved on long pedicels. Flowers are yellow with brown tips and maroon filaments. The fifth photo was taken by Rachel Saunders of the inflorescence of a flower blooming in habitat. The last photo by Uluwehi Knecht shows seeds next to a U.S. 25 cent piece (2.5 cm wide).

From Polianthes on Tuesday 17th of March 2026 05:21:02 PM PDT
Polianthes tuberosa, now Agave amica (Medik.) Thiede & Govaerts, is often sold as "the most fragrant bulb". It was popular in the Victorian era with the common name "tuberose". One synonym is Agave polianthes. It has a long history of cultivation around the world which makes its origin confused; it appeared in Europe around 1600 having been discovered in Central America. Some growing advice appeared on the PBS list here. Height range: 2-3 ft. Photos 1 to 3 by David Pilling who writes: "The second photo shows the result of unwisely planting 10 bulbs in a 12" pot. In a cold spring in northwest England growth was slow to appear, and in future I would be inclined to keep the bulbs indoors until there were signs of life above ground." The last photo by Martin Bohnet shows a plant sold as cultivar "Pink Sapphire", which it clearly is not. As the flowers are somewhat lemon to cream and the smell is present, but not overpowering, it could be the cultivar "Yellow Baby".

From Hypseocharis on Sunday 15th of March 2026 05:17:54 PM PDT
Hypseocharis pimpinellifolia is native to Peru, Bolivia and Argentina. It is a summer-growing plant, blooming from mid-summer to autumn, and going completely dormant in winter. In cultivation, this species is prone to rotting if the tubers get watered during their dormancy. However, they like a lot of water during growth and benefit from periodic fertilization. Plants produce large tubers and can quickly outgrow their pots. It takes 2-3 years to bloom these plants from seeds. Seeds can only be made through out-crossing with a different clone. The photos below were taken by Nhu Nguyen. Photo 6 shows a large tuber that is four years old.

From Dipcadi on Saturday 14th of March 2026 05:07:30 PM PDT
Dipcadi crispum Baker is native to Namibia and the Northern Cape Province of South Africa. Height: 30 cm. The first five photos were taken by Christiaan van Schalkwyk days after an unusual heavy rain in a drought in the Upington area, Northern Cape, South Africa, December 2019, of plants growing in full sun in sand. The last photo was taken by Margaret Fox August 2022 in the Tankwa Karoo.

From Holothrix on Friday 13th of March 2026 05:24:16 PM PDT
Holothrix grandiflora (Sond.) Rchb.f. is distributed from the west coast to the Eastern Cape where it is found on rock crevices. Growing to 30 cm high, it has two basal ovate leaves, often withered at flowering, and large creamy white flowers often tinged apricot pink. The lip is trumpet-like and prominently fringed into 5-9 filiform lobes. It flowers in March, probably best in good rain years.

From Dilatris on Thursday 12th of March 2026 05:48:06 PM PDT
Dilatris corymbosa P.J.Bergius is found on damp sandy slopes and flats in the Western Cape. It is often seen after fire in the Western Cape mountains. Growing 40-60 cm high, it flowers from August to January. The flowers are mauve in a flat-topped cluster with hairy lanceolate tepals. Stamens are about as long as the tepals and the large anther more than twice as long as the smaller. The first four photos from iNaturalist were taken by Tony Rebelo in November in the Western Cape and shared under aCC BY-SA license. The last photo of the flowers with monkey beetles was taken by Bernhard Frauenknecht at Bains Kloof December 2023.

From Geissorhiza Species One on Wednesday 11th of March 2026 06:16:01 PM PDT
Geissorhiza elsiae Goldblatt grows on permanently damp south facing slopes and cliffs usually among waterfalls in the Kamanassie Mountains in the Little Karoo. Growing from 13 to 25 cm, this species has linear to sword shaped leaves and light pink flowers with diamond shaped purple markings in the center. It flowers October to November. It can be confused with Geissorhiza roseoalba, but that species grows in more arid areas, has larger flowers, and does not have anthers symmetrically arranged around the style. The photo below from the book Plants of the Klein Karoo courtesy of Jan and Anne Lise Schutte-Vlok.

Gilliesia graminea Lindl., the type species of this genus, is native to Central Chile to Argentina (Mendoza). This species looks more like an orchid than an amaryllid. According to Chile Flora, this species grows on shaded steep slopes at low altitude, interior valleys or coastal mountains. Height: 8 cm. Photographs 1 to 4 by Bert Zaalberg. Photograph 5 by Dylan Hannon originally from Chile: Cuesta Las Chlieas, 550 m.
