This is a beautiful dahlia. However, only two came up and only one of the two has blooms. Nice green plant but no blooms from the buds. The first one opened but the rest of them did not. The one blossom was very colorful and bright.

We've had a dry, hot summer - more so than usual. A couple of them didn't sprout or come up. One came up but was stunted and never bloomed. The others were very pretty. Especially the pink ones.

They are blooming great and look good. Not all look just like the picture from catalog, but they are still pretty. Could be due to soil, fertilizer, etc

I planted these a bit early, weather only in upper 60s but they did great. Did well in full sun and partial shade. neighbor loves them too! did well through the drought we had with minimal watering. Best color showed up by mid-summer- just like the photo.
