My opinion:
Robin Calderon at Earlybird has consistently good plants, really good prices, and good communication through her website.
Bob Selman at Blue Ridge runs most of his through the Blooming Auction and eBay. I get all mine via eBay. Changed his format recently so most are auction format starting at $10. Easy to get at the price, good communication, nice healthy plants, and bonuses. (He's my favorite
)
Bells and Whistles was $20 and came from Ed Bentley of Bentley Gardens through a mamajack sale.
What can you say about Bill Maryott beyond he has all price ranges and you simply canNOT go wrong here?
