I'm really crushing on 'Carbonero', for its deep cranberry-red color. I want to put in a bunch of 'Stargazer' orientals, and I think 'Carbonero' will echo that color on the center of Stargazer's petals. I'm hoping somebody else will give it a try, because although I can find space for 25 Stargazers, I'm not sure I can also fit in 25 Carbonero LOL
The OT ("orienpet") hybrids seem to establish/persist better for me and for some others in our area, so I'm always interested in them. Some of them get super tall, but many of the newer varieties seem to be noted as the usual 3-4 feet for oriental lilies.
'Acupulco' is one that I had 10 years ago, and I remember it being a bit shorter (2-3') than other orientals... and a really HOT pink color! I didn't put it on the list yet, but I'd pick up 5-10 in a heartbeat if anybody else wanted them...

I think lilies like to be fertilized pretty heavily, but they also co-exist with other shorter plants... those stems need "shoes & socks" plants anyway, and their contractile roots tend to pull the bulb further down than the root systems of most other perennials. So they are pretty easy to "squeeze in."
