Anyone growing these species or have any experience? Anybody have seed or any extra for purchase or trade? I really think these species are interesting and am looking to grow them.

I grow both. I had two L. majoense plants, but the late winter/early spring of 2013 was very hard on species lilies for me here. I lost one of them, along with a nine year old L. szovitsianum from seed, all my L. monadelphums, L. rosthornii and another unidentified trumpet species. I scaled the remaining L. majoense this past fall and shared some with a European friend. My scales seem happy as can be, but no bulblets! The species is self infertile, and my two must have been the same clone, since even hand cross pollination in multiple years didn't even yield a pod, filled or not. Here they are in younger years:

and here's an older one

L. lijiangense has the most beautiful sprouts of all, in my opinion.

It's the only lily susceptible to what seems to be botrytis in my gardens. I lost my original one due to multiple kills of the stalks. Haven't had the opportunity to set seed on my other two, and seedlings, for me at least, grow very slow. Neither ever produce stem bulblets. Sorry, I've nothing to share.

I just noticed both species are on the RHS Lily Group seed list this year. It came out today. See http://www.rhslilygroup.org/ if you're not already a member.

I have seedlings of both growing but can't really comment on their peculiarities and culture yet. Hope to see flowers one day!

Is Rhs like a British version of NALS? Pros and cons?

Thanks for your input Rick and Della.

More or less like the British version yes, but their seed list has a great focus on species lilies. I think there's a much greater variety of rarer species available whereas the NALS list tends to contain more and greater variety of hybrids, especially interdivisional.

Both produce quality publications

After being in the wilderness I (re)joined both only last year, so maybe someone else has more experience to share.
