my lowes has them already blooming. i could never get mine to grow from bulbs

the problem is the big bulb distributors sell them in fall with the spring bloomers. You might find some small ones in a big box store now. Or, you could buy some plants. They take about 4 months to go from corm to flower and that means here in the Dallas TX area I plant in Dec Jan.

Your zone is cooler, so you could probably plant with success now and maybe get a good deal. I love the giant ones and buy them in the fall.

Don't forget to soak them overnight and plant with the claws down.

I placed an order recently for some ranunculus from a place in California called EasytoGrowBulbs.com. I haven't ordered from them before, I'm just going by their positive ratings on the Garden Watchdog. http://davesgarden.com/products/gwd/c/3636/
