I am new to succulents and pretty much hooked. I have amassed a pretty decent small collection (about 10 mixed pots) and I will be able to overwinter them at the botanical garden where I work. Woot!

My question relates to sizing of plants. Since I DON'T have the climate that would enable me to see them growing outside, I am having a hard time figuring out whether the various varieties (especially of my echeverias)will be large, medium or small and how exactly is that defined?

Does anyone know of a list or something that gives general size guidelines for the various types? It seems that my ruffled varieties of echeveria ('Pink Frills', 'Tsunami') are larger but how can I figure out the scale of the various so that I plant them properly?
