Which online source has the most mature peonies?
I've been reading that peonies need a while to get going in the garden, and have noted several sources that people rave about like Hollingsworth, songsparrow and peony garden. Which company has the most mature/largest plants which will bloom the soonest?
Also, if I get peonies from these companies, can I expect blooms in the spring? Can I order and plant now?
