Julia, I have been sitting this one out till I get clearer and do more observation.
I have Lentezone (goes too green for me and has thick long stolons)
Tederheid ( again very long stolons and fast increaser) This season I have one which has been in the same pot "forever" and it has turned a nice bright yellow (nutrient deficiency i think)
Bernstein very slow to grow and most manageable with shorter stolons than the others and attractive burgundy tips.
Unicorn is less gold than all of the above for me and I love how it looks but would never use it as a breeder as it melts in my winters...just freezes and turns to mush
I do not have any of the others.
This thread has helped me to examine these varieties closely and make a decision to get rid of all of them except Bernstein for several reasons. #1 being that the gold color that these are is my very least favorite color. I much prefer a lemon yellow and I have a bunch of lemon yellow seedlings this year which I am really watching. Most are turning a lovely shade of bright chartreuse green for summer. How long they stay green and who goes back to yellow for winter will determine who stays a little longer. None have fuzz but I thing fuzz would dull the glowing bright yellow that I am looking for. They all have great stolon length.
I did use Tederheid on Gold nugget because it was the only other thing flowering at the time.
There may be something in there but the seedlings are too small yet to see much. I think there is a yellow one with fuzz but we will have to wait a year (or 2 at the rate these are growing even with QS) to see about stolon length. I think long stolons is hard to breed away from. ?????
SSSSOOOOO.... Julia and Sol....I am leaving the gold ones for you. Thank you both for helping me clarify my thinking.
We cannot all go in all the directions that present themselves.
