I love how incredibly prolific these are. I only have arenaria x hirta f/Belansky Tatra, Olympicum and an unknown I picked up locally. But I have a LOT of them now. I could easily put some rollers in a paper bag in a small box and mail some for the price of postage, if anyone is interested. Could probably get away with first class postage around $2.00. Some of the rollers on the rollers have rollers. They propagate like rabbits.
