Lachenalia J.Jacq. ex Murray is a genus with bulbs in the Hyacinthaceae family (or expanded Asparagaceae) found in Namibia and South Africa. There are around 133 accepted species (according to Plants of the World, 2018). Most of these have a dormancy period and grow new roots each year. Polyxena has been transferred to Lachenalia by J.C. Manning, P. Goldblatt & M.F. Fay in "A revised generic synopsis of Hyacinthaceae in sub-Saharan Africa, including new combinations and the new tribe Pseudoprospereae", Edinburgh Journal of Botany 60(3): 533-568 (2004). Those species continue to be found on the Polyxena wiki page. Information about Lachenalia from Don Journet was provided on the PBS list in three posts in February 2007. The first was a general introduction and discussion about growing the species, the second discussed propagation, and the third covered pests, diseases, general discussion, and references.
The first complete illustrated systematic monograph of this genus by Graham Duncan The Genus Lachenalia was published in 2012.
Species of Lachenalia are very easily grown from seeds given that they are sown at the right time of year. List members have varied experience but most agree that light is not needed for germination. More detailed information about germinating and growing this genus can be found in the post on propagation from Don Journet noted above.
These lachenalias were being used as bedding plants in Nieuwoudtville in September 2006. They could be cultivars or hybrids although the second photo shows plants that are likely Lachenalia aloides and Lachenalia flava. Photos from Bob Rutemoeller and Mary Sue Ittner. The bulbs look like others in the Hyacinth family. The fourth photo shows bulbs on a 1 cm grid by M. Gastil-Buhl. This last photo shows leaf cuttings with bulbils formed at the base by Colin Davis. Propagation of Lachenalia is quite productive with this method, yielding over 25 bulbils in this instance using less than 2 leaves.
