Last year we pulled COREOPSIS out in haystack-size heaps week after week. This year, it's come back in much more manageable volumes. And now that we recognize it, we pull it out as soon as it emerged, from everywhere except at the back, near the fence. It's in full bloom now, late-June, and stunning. We had three varieties last year, plain yellow, maroon with yellow centers and the reverse, as in the photo above, taken June 19, 2007. This year the yellow with maroon centers came up first. The maroon variety showed up late in June. We haven't seen the yellow-only color yet.
