A couple of weeks ago I bought some Anemone (bulb or corms?) and the package referred you to a website. So I went and checked it out and I have to say it was kind of informative, especially to someone like me who doesn't have much experience with bulbs.
There is a pic of a 'Queen of Night' Tulip on their site that makes my mouth water.
Check out Bulbinfo.com if you would like to learn about Spring/Summer bulbs.
