Hi Christian, Welcome to the list. I think you are correct that what you are growing is an Ixia. One of the challenges of growing and identifying South African Irids is the names are changing all the time with new species added, old names being reinstated, new combinations added, and species that once were known under one name suddenly becoming many species. The SANBI check list hasn't been updated since 2012 although there is a note saying they are working on it. So even if you decide to concentrate on a genus and learn about it, your resource information quickly becomes obsolete. With each new IBSA Journal Rachel Saunders usually makes a note of new species and changes and lists them and there are often a lot. In 2008 in Systematics of the southern African genus Ixia (Iridaceae). 1. The I. rapunculoides complex Goldblatt and Manning made changes to Ixia rapunculoides. Your Ixia could be one of the species in this complex. I've also grown some Ixias from seed labeled Ixia latifolia that resemble your photos as well, but whether they are correctly identified I don't know. There is a photo on ISPOT that looks like your photos that is identified as that species, but an older revision that I have says that species has filaments well exserted from the perianth tube. There is another more recent pdf file you can download from Goldblatt and Manning from 2011: Systematics of the southern African genus Ixia (Iridaceae). 3. Sections Hyalis and Morphixia Both of these have links much too long to go in an email, but you could search for them on Google and find them. Perhaps they might help in the identification. Mary Sue
