I am looking for them too -- the Lowes by me does not have them, nor does Behnke's. Haven't tried Roozen's or Merrifield yet.

The summer bulbs are in at Costco. I am not a dahlia person, so didn't notice the varities, but they had dahlias.

Costco does have Bishop of Llandaff for sale. The bag contains Bishop of Llandaff and Bishop of York tubers.

I have been unable to find these elsewhere in DC, and was about to order some from Brent & Becky's. But I am not a COSTCO member. Is there a chance somebody would be willing to pick me up enough to have two plants each of Landalf and York? I would happily pay you plus swap off other plants...

Lynn,
There are 5 tubers of each variety in the bag (10 tubers total). I would've buy them for you, but they sold them out in my local Costco (Gaithersburg) :-(
I can share my tubers with you if you can pick them up at my home or work. I live in Gaithersburg and work in Bethesda.

Alina, what a kind offer! But I find myself suddenly rich -- my sweetie came back from a visit to his folks in Massachusetts with a bagful -- four BOL and two Arabian Nights. So I have enough for my usual deployment plus a couple spares. But thanks!

Lynn

Good for you Lynn! 'Arabian Nights' are lovely.
I just bought a couple of Collerette Dahlia 'Pooh' and a new hybrid 'Edge of Joy' at Behnke's. About $5 a piece. They also have some trendy Lilies. Surprisingly, cheaper than online. Just in case someone would be interested in...
