From Sparaxis on Sunday 24th of January 2021 04:49:12 PM PST
Sparaxis tricolor (Schneev.) Ker Gawl. has orange scarlet flowers with a yellow center edged with reddish black. It grows on damp clay and stony soils in renosterveld in the northwest Cape and flowers September to October (spring). It is one of the species used in hybridizing and is widely cultivated. Growing from 12 to 30 cm, it is very similar to Sparaxis pillansii, but differs in flower color and in having anthers that are not twisted and and yellow to ochre. The first photo was taken by Arnold Trachtenberg at Wave Hill and the next two by Mary Sue Ittner including the corms on a 1 cm grid.

Photos 1 to 3 taken by Mary Sue Ittner and Bob Rutemoeller are of plants seen flowering in Nieuwoudtville September 2006. Photos include a close-up with a beetle pollinator and the last shown with Lapeirousia jacquinii. The last two photos were taken by Cameron McMaster near Nieuwoudtville September 2011.

From Ledebouria on Wednesday 20th of January 2021 04:36:18 PM PST
Ledebouria hypoxidioides (Schönland) Jessop is native to the Eastern Cape Province, South Africa where it is confined to the hills around Grahamstown. The leaves are hairy with ciliate margins, making this species the only one in the genus with pilose leaves. The leaves are fully developed at flowering. The tepals are lanceolate and seeds are reddish-brown. In the San Francisco Bay Area, this species does not go completely dormant if some water is available in the winter. However, too much cold and winter rain can cause rotting and browning of the leaf tips as seen in the photos below. The first three photos by Nhu Nguyen. Photo 3 shows the pilose nature of the leaves. The last two from Cameron McMaster.

From Xeronema on Tuesday 19th of January 2021 05:50:52 PM PST
Xeronema callistemon endemic to Poor Knights Island and Hen (Taranga) Islands in northern New Zealand grows on rhyolite sea cliffs and rock outcrops and occasionally on rubble in forests or as epiphytes on Metrosideros excelsa. They form huge colonies 1-4 m across. The flowers are red in dense racemes on scapes that are up to 1 m long. Flowers appear in spring. They are not threatened, but because they are endemic to two very small islands they are listed as such. There are two recognized subspecies: X. callistemon var. callistemon and X. callistemon var. bracteosa
According to the New Zealand Plant Conservation Network, Xeronema is best grown in a long narrow pot in a free draining mix of rock chips and compost. They should be watered frequently and fertilized frequently with sea weed, manure, or a high phosphate/nitrogen garden fertilizer. The Network says they're very cold sensitive dying even in mild frosts, but Lee Poulsen haven't had any such problem with his where they've withstood temperatures down to 0°C or lower (-1° or -2°C) with no signs of damage or harm whatsoever growing outdoors all year round without any protection here in Southern California. The one thing they can't withstand is overheated roots; this will kill them very quickly. The plants should be allowed to become root-bound or they won't flower, and need good sunlight. However, good sunlight in New Zealand is not quite the same as other places. In the San Francisco Bay Area, plants grown in full sun are extremely stressed and need to be grown in partial sun or part shade.

From Xanthorrhoea on Monday 18th of January 2021 04:22:16 PM PST
Xanthorrhoea preissii grows in Western Australia in various habitats. It has an upright trunk and can reach 5 meters with a trunk of over 3 meters. It has yellow root tubers that are ephemeral lasting from April till January. Plants bloom between August and November with flowering enhanced if plants have burned the previous summer. The spike can be 1 to 3 meters high with numerous flowers crowed on the upper part of the scape. Photos taken by Bob Rutemoeller and Mary Sue Ittner September 2007 in southwestern Western Australia show plants and flowers as they open on the spike and are pollinated.

From Tritonia Four on Sunday 17th of January 2021 05:46:19 PM PST
Tritonia squalida (Aiton) Ker Gawl. is very similar to Tritonia crocata but has pink or mauvish pink to almost white flowers with deeper pink veins and claws with hyaline marginal zones. It has almost regular cup-shaped flowers which make it look very different from many of the other species. The flowers are very beautiful in spite of the ugly species name which refers to the dirty mauve color of herbarium specimens. It is found on limestone outcrops and calcareous sands in the Southern Cape. Photo by Mary Sue Ittner.

From Cyanicula on Saturday 16th of January 2021 04:35:44 PM PST
Cyanicula amplexans, syn. Caladenia amplexans is a small orchid with one dark green leaf and 1 to 2 flowers on a thick wiry scape growing to 20 cm. The flowers are blue and about 2 cm. across. This species is native to Western Australia where is it found in shrubland, she-oak thickets, and mallee scrub. Photo by Bob Rutemoeller taken September 2007 near Pemberton.
