You've listed named hybrids. They won't come true from seed. You might get a small percentage that look like the parent plant. Also, some of the modern hybrids do not set seed. Usually only the wild species are started from seed, unless you are interested in creating new hybrids.

lilydude, you mean the seeds that come from the pods when the lilies dry out right? They look like "crushed pepper" you'd put on pizza, yes? I've wondered whether they would form a viable plant. Please advise.

When the pods turn brown and dry, they split open and seed is dispersed by wind. Lily seeds are shaped sort of like lentils: flat and roundish. If the seed is thin as paper and transparent, it is not viable. If it is thick and has what looks like a tiny root inside, it may be viable. Good seeds are roughly 1/4" across. The only way for an amateur to test viability is to plant the seed and see if it grows. This is tricky, since different types of lilies have different germination requirements. For more information, visit the Yahoo Lilium forum or the North American Lily Society website, or use Google. The NALS articles are ultra-cute and ultra-optimistic, but still have some good information in them. In my opinion, growing lilies from seed is a fairly specialized skill and requires great patience. So I don't know why some people say it's easy. Maybe they are very good growers, so it's easy for them.

For hybrids, you are much better off doing vegetative (asexual) propagation, such as scaling, stem bulbils, etc. The resulting plants will be genetically identical to the parent plant. The disadvantage of this method is that viruses in the parent are transmitted to the offspring. This does not happen with seeds.

FASCINATING lillydude! Thank you. Now, when is the best time to scale/propagate them?

Google "scaling lily bulbs". Tons of info out there.
