the real obvious, Julie or the "improved" Juliette
Mahachanok, while not a dwarf, it is a slower, more compact grower...then again, I would not consider Cogshall a "dwarf" either.
Angie, from what I have seen, falls under that slower, more compact grower though not a dwarf. There will be a handful of plants available in a month or so...as far as budwood, might be tough though I am sure there are some givers out there
I believe Kesar is also a slower, compact grower...again, not a dwarf.
For a late season variety, try Neelam...with its growth habit and a good set of pruners it should do you right.
