fall crocus and colchicum planting time?

This link, http://www.gardenguides.com/articles/fallcrocusandcolchicum.htm, makes me want to plant some crocus and colchicum bulbs. Plus crocus are apparently perennials, which makes me like the sound of them even more. I don't have much money to spend this year, so rather than doing a full planting perhaps I'll just put a few in a pot or flower box.
