Your Scheff looks grossly overwatered to me.

Indeed - if only this species were easier to propagate/grow. Alas, it is a tough one.

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).

I live in gardening zone 5b, Central IL, and while I love roses, I despise plants that require babying. With this in mind, I only grow own-root (not grafted) roses, usually rated for zones 3, 4, 5, and sometimes 6 if I have a protected backdrop to plant them in front of for frigid winter wind and ice/cold protection. Every rose I grow in a container gets placed inside an unheated garage once the cold sets in during late autumn. I keep an eye on moisture, only giving some when the medium gets fairly dry. when it does snow, I bring a shovelful of snow inside the garage and set the snow on top of the pots' soil. I love scented roses, continuous blooming roses, and I try to include Rosa Rugosa Alba or Rubra for their hip production, which I use in jams and jellies. My favorite place to order roses from is HeirloomRoses.com as they have a wide variety of every hardy rose grown on its own root-stock. Plus, they often hold sales, which I like! I've had wonderful success with Canadian roses, Griffith Buck roses, a few German and French varieties, miniature roses (which are always grown on their own roots), and a few more. The adage: "the 1st year they sleep; the 2nd year they creep; and the 3rd year they leap" holds true in that during the first year, they spend energy growing a good root system, the second year they begin to put on growth above the soil, and by the third year they should be leaping toward plant growth and flower production... which is, in essence, the plant trying to reproduce via bloom/pollination and subsequently seed. Roses are heavy feeders and thirsty plants. To avoid mildew and other issues from water on leaves, I water using soaker hoses when there is no direct sun on the plants, the dripping pointed downward, the hose slightly buried in the pine bark mulch I use to help keep moisture around the roots. I use several inches of decent mulch. I feed them using Bayer 2 in 1 systemic Rose & Flower Care which also helps keeps early season aphids and white flies from harming newly forming buds. I also have chickens and ducks, so I take advantage of the fertilizer to be had in the form of the duck's dirty pool water, which is watered down and won't burn the roots. I call it "duck poop soup". It helps quite a bit. I do avoid chicken manure, which is too fresh and will burn plants and their roots. Duck manure, especially watered down in a baby pool, due to its low acidic level, can be used right away and is natural/organic. Tea Roses don't do well in my zone, but so many others do extremely well! I have "Therese Bugnet" planted near our mailbox, which is very fragrant! The "Rosa Rugosas" are very fragrant, as well as giving of decent sized hips. "Darlow's Enigma" is fragrant. "Alchymist" is very scented! There are plenty of others, but those are some of my favorites. As far as pruning goes, since we live on a small farm, I have space to allow growth, so I am only concerned with removing dead canes, and I am sure to seal each diagonal cut to avoid borer bees and other insects boring into the cut canes. Miniature roses often grow into lovely little shrubs covered with color! Sometimes, these can be found sold in 4" or 6" pots as indoor plants, but since they are own-root I plant them directly out in my garden as perennials. Plus, they really don't do well as house plants, requiring 6 to 8 hours of sunlight per day. "Quadra" is another favorite... deep red quartered blooms that smell very nice, and look so pretty! I hope this adds a little bit to the advice given by everyone else! Happy Gardening!
