Your Scheff looks grossly overwatered to me.

Dianthus barbatus (Sweet William)? Here is a link that might be useful: Sweet William

We are looking at China White and Dove Wing....We can barely tell the difference and are torn by the samples. Natalie W, you have a great eye for picking out colors that are similar to each other! China White and Dove Wing are very similar, with only a delta 0.1 difference, not enough to be perceptible to the human eye. Both of those colors are in the same hue family as KM Swiss Coffee. However, they are also very close together chromatically, and we recommend a difference of at least 0.2 for contrast. Swiss Coffee has a chroma of 0.52, China White 0.66, and Dove Wing 0.69, so any of these two colors together are going to look like the same color from a distance. If you'd like more contrast with the ceiling, you could try BM Gray Mist (chroma 0.82).

The flowers match, but I can't see anything that matches the leaves in the 2nd photo. I see Clematis leaves both lobed and entire. The Thalictrum leaves must be hidden. Most Thalictrum have their leaves in a low rosette that's easily hidden. Thalictrum aquilegiifolium
