Re: two simple questions

Caron:
I also live in Colorado and would like info on the nifty handbook you described.

I've tried a few different ways with each species and have had mixed results.  It feels to me like the most successful attempts are the ones where I come closest to reproducing what's actually happening on the hillside where I collected these seeds.  This make sense to me.  In fact it feels sort of like I'm in a battle of wits with these conservative little guys in which I'm trying to convince them they are still on the hillside and it is spring.

The first is the need to start seeds in a nutrient poor medium.  The second is the practice of covering the seeds with something opaque, like a folded newspaper, until they germinate.
