In addition to those already mentioned: 'Elvis' is a brilliant shade of red. Really quite different and one I'll be using in breeding when it grows up a bit and produces flowers. 'Purple Dazzler' has changed colors a good bit but is starting to have a dark purple base appear. 'Dark Cloud', 'Plumb Rose', 'Viking', 'Eomer', and 'Jungle Shadows' are paler but still have good color. Ditto the plants I'm naming for 'Polly Bishop' and 'Helen Payne' that are 'Jungle Shadows' seedlings.
I think we have a special price on 'Borscht' just for you. $150! Just kidding Lynn! I think she might actually be considering it even at that price. One of the siblings is looking very good too. It is a bit smaller and a more purple shade than 'Borscht' but also with strong watermarks that are very cool. Both of these have great color year round. The increase that are coming on 'Borscht' are really intensely colored. Thank you 'Killer' for giving such wonderful seedlings.
Some of the heufelliis have great color retention. one of my seedlings is like a more extreme version of 'Vesta' and it has stayed red-purple with a sliver of green at the tips all summer. Seems to be a vigorous increaser too.
