By the time you've paid postage I would have thought you could buy a pack as cheaply and easily. You're looking for Iberis sempervirens 'Snowflake' which perennial so you only need to get it once.

Hi, thanks for your response. I have looked into buying seeds, but the cheapest I found is $4.75 with shipping. I figured if someone was willing to share a little bit of seeds, shipping might not cost more than a couple of stamps (from within the US). Which is less than a dollar. :) (I am frugal..or trying to be.)

You could ask on the Seed Exchange Forum.

Ha..that's where I thought I posted this. LOL. Thank you for the link. Not on here very often and still not used to this site. :)
