No idea what the craze will be this year. There are certainly a few hybrids that I would like to get, but Australia is usually a few years behind the US, so what's "new" down here (unless it's an Australian hybrid) is probably old news to you!
Hardiness is something I am also looking for (especially something that will stand up to the Australian summer). I am fast learning which hybrids (and species) do and don't like it here. Orientals are a real struggle where I am; I have one last spot to try around the house to see if they like that location. If not, then I will probably give up entirely on them for the moment.
Asiatics are my favourites (probably because grew up with them). Our commercial Leichtlinii (which I've read is a selection of 'Citronella'?) seems to do well here. 'Red Velvet' is another (which I see Connie has also mentioned).
Martagons: these are lovely but technically "shouldn't" grow here. They get no winter freeze and can have two growth cycles (spring and autumn). Interestingly I have had more success with the species than the hybrids (although I am now testing out Australian hybrids - some from seed, thanks to
@vanozzi - and some from Cam Lilies - thanks to
@dellac for pointing them out).
I have plenty of Aurelians (Div. 6) courtesy of
@vanozzi, who generously gave me a large number when he divided his hybrids. Quite a number of these grow well here, although some do not like the full sun. I'm trying my hand at hybridising to see what I can do to improve the heat tolerance and colourfastness.
I have yet to really explore Orienpets (small range available here), but I now have some seeds to try.
Species Liliums are an ongoing experiment for me, as I am keen to try to grow as many as I can. Almost all have to be grown from seed here; occasionally one or two become available as bulbs. So far I have definitely managed not to kill
L. candidum (seed-grown),
L. pardalinum var. pitkinense (seed-grown) and
L. martagon var. albiflorum (purchased as bulbs), whilst some others are proving a real challenge (and sometimes it's hard to tell whether I've got something wrong or the seed is just dead - I'm looking at you,
L. taliense).
