Fool me once

In the front, next to the walkway I have a flower bed with three large roses. One is a Tiffany hybrid Tea, a beautiful pink with a yellow interior. One is a red rose whose name I do not recall, but that has a deep rose scent. One is a yellow floribunda on a red climbing rose root stock. I know that the root stock is a red climber because it has sent out shoots. I actually like the shoots, except that they have nothing to climb and if I let them grow too much they will take over and I won't have the yellow floribunda.
Underneath the roses I have a rock garden and I plant miniature flowers. I have miniature daffodils in the spring, and I have johnny-jump-up's, which reseed themselves nicely. I have allysum, which also reseeds itself, probably too much. And then I have English daisy's and miniature daisy's. Both of those, particularly the miniature white daisy, when they are very young look very much like weeds that grow here. I am afraid I have pulled out baby plants, thinking they are the weeds and now I have too few in the bed. I have replanted English daisy seeds but haven't yet seen signs of new plants. Buying the plant itself is a bit expensive, leading me to believe that others have trouble getting them to grow as well.
So, for this year at least, I have added some portulaca and some verbena, both of which look very good, and some purple salvia, which aren't doing well at all. Too little water maybe? I don't water often. Still the overall bed, (other that needing to be weeded more) looks quite good. Come see!
