Ditto, chasmanthe and vinca....at least the chasmanthe is favored by the hummers and the vinca really was not too much bother in pulling. When we moved up here, I noticed several stands of what looked to be chasmanthe in bud, but fortunately turned out to be a 'nice' orange crocosmia. I have different nuisances here than I'd encountered before...ranunculus repens, for one...another, what I think is Ox-eye Daisy, lots of rampant growers, but I'm leaving large areas (for my tiny yard)as wild meadow and I will let these grow to a certain extent.
