I have a Mountain Bells mixture that I ordered from Brecks. NOWHERE can I find any info, online or otherwise, about what kind of light to plant these in!!!
I'd guess, but, I've been wrong before.
What do they like?
Mountain Bells? Could be any one of half a dozen plants. I'm going to guess these are the little Allium bulbs.
Allium want full sun or a little shade. Too much shade and they won't flower well and will tend to be more floppy then normal.
And, my fault for not seeing that it says 'Full Sun to Partial Shade' at the Breck's site for the Mountain Bells! (Link below.)
Here is a link that might be useful: Breck's Mountain Bells Mixture
Also, they don't tell you this on the website, but when I received my bulbs, the label states they're a mixture of Allium moly, A. oreophilum, and A. neapolitanum. :)
