Lachenalia is a genus with bulbs in the Hyacinthaceae family found in Namibia and South Africa. There are around 110 species (80 of those are found in the Cape region.) Most of these have a dormancy period and grow new roots each year. Lachenalia species U-Z are found on this page.

Lachenalia unicolor is found in heavy soil in large colonies from the Bokkeveld Mountains to Somerset West. It has flowers on long pedicels in many different colors with green or purplish markings and blooms in the spring. Photo 1 by Mary Sue Ittner shows plants flowering in Clanwilliam September 2006. Photos 2-5 are of plants in cultivation. Photo 2 by Mary Sue Ittner. Photos 3-5 were taken by Nhu Nguyen. Photos 4-5 were taken at the UC Botanical Garden.

Lachenalia violacea is distributed in the northwest Cape and Namaqualand where it is found in various habitats, but often in rocky places. It flowers late winter into spring. The first photo taken by Bob Rutemoeller of plants in Alan Horstmann's collection and the next two photos by Bob Rutemoeller and Mary Sue Ittner taken early morning near Middlepos in the Roggeveld in September 2006. Photos 4-5 were taken by Cameron McMaster in the Roggeveld September 2011. The last photo was taken by Cameron McMaster in the Nieuwoudtville Reserve in the Bokkeveld Plateau.
Lachenalia viridiflora W. F. Barker This species has turquoise flowers and is an early bloomer, blooming in winter. It is found on granite outcrops in the southwest Cape. Compared with other species the color is remarkably uniform over the entire flower with just the tips of both inner and outer segments being markedly darker. It flowers relatively early in the season. The first photo by Digby Boswell and the next two photos taken by Susan Hayek at Telos Rare Bulbs Nursery owned by Diana Chapman. This Lachenalia is interesting to photograph because on the camera the turquoise color virtually glows. The final photograph by Pamela Slate shows bulblet formation on a leaf cutting.
The photos below by Nhu Nguyen shows two different forms from above. Photos 1-2 show a very brightly blue colored form. Photos 3-4 show a form with green petal tips.
Lachenalia youngii Baker is found in coastal areas in the southeast Cape. It has two leaves and bell-shaped flowers on long pedicels that are pale blue and pink with darker purplish pink markings. Photos from Cameron McMaster.
Lachenalia zebrina is a striking species with one ovate pale arching green leaf that is banded with purple and creamy flowers fading to red on long pedicels. Anthers are well exserted. It is found on rocky clay flats in the Western Karoo. Photos by Bob Rutemoeller and Mary Sue Ittner taken of the leaves September 2006 near Middelpos in the Roggeveld. The third photo was taken by Rod Saunders. The last photo is of a plant growing in a disturbed area near the village of Loxton by Rogan Roth.
Lachenalia zeyheri is a late blooming species that grows in marshes and seeps in the Northwest Cape. It has bell shaped white flowers with reddish brown or green markings. The first two photos by Alan Horstmann and Mary Sue Ittner. The last two were taken in habitat near Blinkbergpas in the Western Cape by Andrew Harvie.
