Oops, I did it again!
Went back and bought two more of the on-sale Monrovia citrus standards, a Dancy and a Satsuma. These were a little pricier, ended up being $49 each on sale, 30% off the regular price.
So, that now means I have my previous ones, a large Trifoliate orange, a standard Washington Navel, a shrub form kumquat, a bush form lemon, two smaller oranges from Lowe's 50 cents on the clearance rack 4" pots, and now a new lemon and two new C. reticulata.
I still want that grapefruit tree! And I was sorely tempted by a variegated kumquat they had for $90 but it wasn't part of the sale lot.
