Dear Tsuh Yang, Don Journet is offline at the moment or he would surely respond to your question. He wrote a very interesting article on his experiences growing Lachenalia in Australia in the latest BULBS. I have found in growing Lachenalia that a lot, but not all, of the ones I grow split into smaller size bulbs. It is curious looking at the offspring as they are often attached and very irregularly shaped. Others produce tiny bulblets and some at a distance. I grew Lachenalia aloides quadricolor in a raised bed for years and every year it bloomed well for a long time in winter providing a most welcome bright display during dreary weather. Eventually I got rid of it because the leaves were looking possibly virused even though it was continuing to bloom. I usually repot my Lachenalias every year (at least the ones I grow in containers.) It seems to be a genus where some of the bulbs get diseased and that allows me to toss any that look like they are not healthy and repot the rest so they have plenty of room in the medium. This may require an additional pot or disposing of offsets. Since it is a genus with interesting leaves and a long bloom time, interesting flowers, and occasionally wonderful fragrances I am willing to do this. Most of them (if they come up which they don't always) usually rebloom well once they get to a certain size. In Don's article if I remember correctly he said that over time you might have to start over with some of them as they run out of steam. They are easily grown from seed. I finally got seed of L. aloides quadricolor and am going to do just that since it was one of my favorite winter blooming flowers. Another Lachenalia that I am finding is really prolific is L. mutabilis. I've got it planted a couple of places in the ground and it is doing fine. Also I am finding it in other pots so perhaps I need to be more watchful. Another Lachenalia that I admired years ago in African Hill, UC Botanical Garden, Berkeley, is L. contaminata. I wasn't very successful with my attempts to mimic this in my original raised beds as it was erratic. But I have it in quite a few pots blooming right now (labeled unknown Allium? since the bulbs looked like some of my Allium bulbs) as well as in containers named in its own right. Some of the now identified bulbs are going in the ground next year and I'll try again with it in the garden.
