I got it from High Country Roses late in April or May and it was just a tiny quart...I think I did everything wrong and had too heavy of soil...the pot is about 18x 24 inches and it has snap dragons in it too. The poor bush is only about 2 feet high, but bloomed and bloomed about 2 months after planting and only stopped when we had heavy frost in November. I am guessing it will get bigger, but one grower on youtube said that potting roses can control size. There also is a bonsai guy on youtube that moves things in and out of pots regularly.
I just got back from an out of the way Homedepot and they had most of their pots and planters on clearance, so it might be worth checking your Lowes or Homedepot if you are looking for pots...of course, yours may have a different gardening cycle than mine.
