From Mendocino Sonoma Coast Two on Saturday 24th of February 2024 04:21:02 PM PST
Calypso bulbosa var. occidentalis is found in moist woods and is one of the early spring wildflowers that people delight in seeing each year. The first three photos from Mary Sue Ittner were taken at various locations in Sonoma and Mendocino Counties between March and May. In photo #3 a spider web has captured some insects. Photos #4-5 from Bob Rutemoeller show the new leaf with an emerging flower bud and a close-up of the flower. The last photo taken by Mary Hunter shows a rare white form.

From Geissorhiza Species One on Friday 23rd of February 2024 07:03:28 PM PST
Geissorhiza aspera Goldblatt 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 next two by Cameron McMaster at Hermanus and Jacobsbaai and the fourth by Mary Sue Ittner at Darling. The fifth photo taken by Rod Saunders near Malmesbury after a burn was originally thought to be a new species, but subsequently was determined to be a different form of this species. The last photo from the book Plants of the Klein Karoo courtesy of Jan and Anne Lise Schutte-Vlok.

Photographs by M.Gastil-Buhl show seed acquired from Silverhill Seeds on a 1 mm grid in photo 1 before germination and in photo 2 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 3 has several leaves in its second year of growth. Photo 5 shows it blooming in March. The last photo shows corms from these same seeds 4 years later.

From Lilium Asiatic Section Three on Thursday 22nd of February 2024 07:03:22 PM PST
Lilium nanum Klotzsch, syn. Nomocharis nana (Klotzsch) E.H.Wilson, is an alpine species native to the Himalayas. It is a short species, growing 16 to 34 cm (7 to 15 inches); the floret is outward facing, pale pink spotted with purple. The foliage is narrow and long; it grows in a very upright position and can extend from mid-point on the stem to well above the flowering tip. Photos by Pontus Wallstén.

Lilium nanum var. flavidum(Rendle) Sealy is much like the type in foliage and height, but the florets have an outward and downward orientation, aren't as widely opened, are yellow, spot free, and have a light blue stigma. This lily is an early flowering species; in zone 1 it flowers by late June or early July and senesces ("browns down") by early to mid August. It enjoys a high humus well-drained acidic based soil. Five photos of L. nanum var. flavidum were submitted by Darm Crook.

From Ceratandra on Wednesday 21st of February 2024 04:07:34 PM PST
Ceratandra globosa Lindl. occurs from the Cedarberg Mountains to the Eastern Cape. Growing to 30 cm tall and flowering in the first year after a fire in summer, this species has white and pink flowers. Photo from the book Plants of the Klein Karoo courtesy of Jan and Anne Lise Schutte-Vlok.

From Erythronium Three on Tuesday 20th of February 2024 04:46:21 PM PST
Erythronium helenae Applegate is a rare species found in dry serpentine soils in oak and pine woodland and chaparral in Napa and Sonoma Counties, California. It appreciates warmth during its summer dormancy. Leaves are mottled and it has large white widely opened flowers with a yellow base, yellow anthers and auricles at the petal base. On warm days it smells of orange blossoms. First photo by Ian Young. Photos 2-5 were taken by Mary Sue Ittner. Photos 2-3 show plants in cultivation grown from seed and 4-5 are of plants seen growing on a gravelly bank in Lake County very close to Sonoma County.

From Pillansia on Sunday 18th of February 2024 04:40:57 PM PST
Pillansia templemannii (Baker) L.Bolus has linear leaves without a midrib and flowers in a panicle instead of a spike. It has orange bell shaped flowers and grows in nutrient poor sandstone soils or in seeps. It rarely flowers except after the surrounding vegetation has been burned and then it flowers in mass. It does not respond well to cultivation. The first photo by Rod Saunders. The next three photos from iNaturalist taken by Tony Rebelo in the Overberg in November and shared under a CC BY-SA license.

From Sinningia Species on Saturday 17th of February 2024 06:45:04 PM PST
Sinningia sp. photo was taken from the northeast of Argentina by Germán Roitman who identified it as Sinningia stricta (Hook. & Arn.) Wiehler which is a synonym of Sinningia elatior (Kunth) Chautems. It is a plant with big tubers and pale red flowers that are visited by hummingbirds. Note from John Ingram: "this photo looks a lot like what should be labeled as S. warmingii. S. warmingii has straight corollas while S. elatior is dorsally curved." Both species can be found in Argentina. Sinningia elatior is listed on Plants of the World Online as distributed in northeast Argentina and the photos there look very much like this photo.

From Eucomis Three on Friday 16th of February 2024 05:45:59 PM PST
Eucomis humilis Baker is endemic to the Drakensberg alpine region where it is found in rocky stream gullies, wet rock overhangs, and in grasslands. It is a dwarf species growing up to 40 cm. It has keeled leaves with wavy margins tinged purple and is spotted purple below. The inflorescence has a dense tuft of small bracts edged purple and the stem is spotted purple. The flowers are greenish white tinged or edged purple with purple stamens. It has an unpleasant scent. It flowers in midsummer, from December to February, after which it produces capsular fruits.

From Merwilla on Thursday 15th of February 2024 06:35:46 PM PST
Merwilla plumbea (Lindl.) Speta, syn. Scilla plumbea Lindl., from southern and east subtropical Africa, has hispidulous or glabrous foliage but a consistently glabrous scape. In 2019 in a paper by John Manning entitled Systematics of the sub-Saharan African squills: The genera Merwilla, Pseudoprospero, Schizocarphus and Spetaea (Hyacinthaceae: Scilloideae) two subspecies were recognized. Merwilla plumbea ssp. plumbea, syn. Scilla natalensis, Planch. included the subtropical Merwilla lazulina (Wild) Speta. Merwilla plumbea ssp. kraussii (Baker) J.C.Manning, syn. Merwilla kraussii (Baker) Speta, was recognized for dwarf forms of this species from the southeastern coast and near-interior of South Africa. It appears to be hardy to Zone 7 and tolerant of rain during the winter although it is not hardy and will die with hard frost. With regular water it may remain evergreen. It has been described as flowering in spring, summer, and fall perhaps depending on when it received water. Sometimes the leaves appear after the flowers. It was the subject of an extensive discussion on the PBS list in March 2003. The first picture is of a large clump in the UC Botanical Garden when they were dormant followed by more pictures of spring blooming plants at UC Berkeley in early and later phases of bloom and showing how they need a lot of space. The first three photos were taken by Liz Waterman and the fourth by Kelley Macdonald. The last photo was contributed by theUC Botanical Garden showing a nice inflorescence.

The first picture of the flowers with the sky in the background was taken by Bill Dijk. The second photo by Jana Ulmer shows a first bloom emerging in March 2003 from a plant started from seed in December 1997. The third picture is of one blooming in the southern California garden of Doug Westfall where it is growing in a container. The fourth picture taken by [Uluwehi Knecht|Uluwehi Knecht]] captures the beautiful color and texture of fresh spring growth. The last photo by Martin Bohnet shows ripe seed capsules opening up. Collecting seeds is not trivial, as the dry seed capsules tend to hurl the seeds away when brushed gently.
