Starting Echinacea-Ruby Star, others

I received some Ruby Star Echinacea seeds and now that it's too late to Winter Sow, can I still expect to get decent germination? Any germination?

I start seeds, some perennials and some annuals, outdoors in May in a really large pot that I use later for mixed plantings, after I transplant the seedlings. One year I tried several different kinds of Echinacea seeds and not one germinated. A friend mentioned that I should have winter sowed them to get germination.

I recently read an on-line article that said growing Echinacea from seed works well with stratification, but that Purpurea varieties will germinate without it.

Your thoughts before I plant, please? Thanks,
Linda

E Pupurea isn't dependent on stratification taking into account the freshness of the seed and how it's been stored, but the moist chill can improve germination. One reliable suggestion is to sow, if no germination in 3-4 weeks, move to 40F for 2-4 weeks then bring back to warm.

You may have to deviate from your large planter, but why not (for the sake of saving time) assume they will benefit from a brief moist chill, sow in something like a 4" pot, wrap in saran and put that into your refrigerator for a couple of weeks, then place outside.

I could probably do that, morz8. They can join the pot of Electric Blue Penstemon seeds that is already in the refrigerator!

I have about thirty Ruby Star plants now in four inch pots in my coldframe. They were started in my unheated greenhouse on heat mats maintaining 70 degrees. No pre chilling or stratification was needed for good germination. Al
