I grew up with the impression, based on parental tastes, that one ought not to like dahlias, and indeed I find many types unpleasantly stiff and oddly colored, as if they were badly tinted plastic. But they have a sturdy reliability in this region which appeals to me. This year I tried a pack of Fresco Mix around the toes of the new crape myrtle, next to the rescued coreopsis. They are short, mostly shades of red with one or two yellows. Just now they are surging into a new round of bloom, in spite of the heat and storms we've had. The yellow centers match the coreopsis. I mean to plant lots of them next year.The only disadvantage I can see is that, like begonias, they don't seem to attract our local pollinators. I can't recall ever seeing a bee, wasp, or butterfly visit them.
