I was thinking of the place in full shade under the live oaks for the impatiens but that area is loaded with wild blackberry canes that will have to be dug out and eradicated.
Right now I'm concentrating on the less problematic areas - the terraced beds right around the house, most of which get full sun, and the bed under the post oak that is not in full shade.
Everything went to weeds last year while I was getting my new knees installed. This year I am salvaging what survived the weeds, and trying to plant stuff that might be able to crowd out the weeds eventually.
On the south side, I dug out all the daylilies the deer have been eating and planted them in the top bed with the hope the deer won't come up that high to graze. I dug out all the paperwhites and African Iris - gave away a bunch of them and transplanted more.
Yesterday I planted 15 hybrid bandana lantana in the south bed; today five on the east and one one the west corner as an accent. A flat of salvia went in the window box and in the front bed for some color. I even found some agapanthus I didn't think had survived and transplanted them in that top bed.
I'm hoping the lantana will take over that south bed - they can get big here and I got the multicolor varieties so they should be really pretty. And deer won't eat them so that should help!
