MR,
There is no such thing as "rehabilitating a plant"! They aren't all lovely or else we'd be growing weeds instead of semps! MUCH easier!
That's why we have to be DISCRIMINATING otherwise we just get a pile of trash.Out of a thousand or so seedlings there might be one or two that should be marketed. The rest will be too close to something already on the market, a poor copy of its parent or WORSE. The only other reason I might save a seedling is to use it in breeding. For example, a sibling of 'Polly Bishop' showed a bit of yellow coloration and I self-pollinated it to give me a crop that are showing a few that are much more yellow. Even these might not be marketed unless they are superior in all other qualities. The parent that shows the small amount of yellow will NEVER see the market.
The odds of producing something good out of random seed are astonomically small as the bees have randomly crossed the parents. Generally that makes muddy things, typical of F1 crosses of reds or purples with greens. I do grow some open pollinated seed of rare cultivars that may be blooming out or things not available in the US so that I can use the seedlings in further breeding.
Hope that clears it up!
Kevin
