Randy - thank you for posting your pictures. I recall Bob's plants but they had a semi-oak elongated leaf. I was surprised when the one that came from you started developing some oak shape leaves. Mike Woolery (Bullwinkle) was checking out my plant yesterday afternoon. Seeing it in person, he mentioned that it did have similarities to Tally and thought it could not be ruled out. The different looks to the Bob Sanbourne Hybrid could be attributed to the fact that Bob does not fertilize except with the free horse manure in his area. This may explain why in the hands of those who are more chemical fertilizer conscience - this plant has the oak leaf characteristic.
How is the one looking in your garden? The last I saw it (Jan. 1) it looked like you had done some recent cutting on it.
