Silvermans up on Sport Hill has them, but not that many trees of them (or did, we got some there last year or the year before).

Though we usually swing by Aspetuck after breakfast for them, it's easier then dealing with the crowds at Silvermans (and the prices are better)

If you make a trip of it, Lymans in Middlefield has them, as does Drazen in Cheshire. We use to get our mums in Cheshire, and I had family in that area, so we would do it all at once. Though this year the mums at Aspetuck are wonderful and cheap, so we won't be going to Cheshire.
