ornamental grasses

Hello,
I am a collector of ornamental grasses. I also work on my website in Polish language which is going to be dedicated to this plants. I couldn`t find any more information about Calamagrostis x acutiflora `Avalanche` and Carex firma, so I`d be grateful to all of you for some more. I would like to know such a details as botanical names and synonym(s), height, bloom height, bloom time (but in which months exactly the plant used to bloom), growing conditions (kinds of soils, full sun or shade, humidity), foliage color, zone. If there is there anybody who has such a information and would like to share it with me, I will be really happy. Please send me an e-mail back to: [email protected]
Best regards, Anette
