I've long read Banksiae seed can require two years to germinate. I've raised four seedlings from open pollinated Lutescens. Two have been fully double and one semi double with tulip shaped buds. The fourth succumbed to terminal mildew in infancy. This double yellow Banksiae is from OP Lutescens seed.

April 29, 2024: Kim, your double yellow banksiae flowers from the hip of single yellow lutescens parallels the experience I had raising my first lutescens from seed. I read that Jesse Mould, who lived on the Banks Peninsula in New Zealand had the single yellow lutescens. I wrote to her and In 1991 she sent me 29 hips from which I recovered 67 seeds. Seventeen seedlings sprouted, with the first blooms appearing on two plants in 1995, both single white. In 1996 five more bloomed, three single white, one double white and one double yellow. In 1997 another single white and a double yellow. In 1998 the last eight seedlings bloomed and I finally got three single yellow lutescens with three double yellow, one double white and a final single white. So the final score was seven single white, two double white, five double yellow and the three single yellow lutescens which was just under 18% of total seeds sprouted. It took seven years from planting to finally get those three lutescens!
And in addition to all four flower types, there was variation in smooth or prickly canes, too. I did not positively confirm that all the hips came from Jesse’s lutescens plant but I can’t imagine she would mix in the other species or whether she even grew them since I specifically wrote about and asked for lutescens. I’ve read others had a similar experience with seed from a single source. Could it be that a single plant can produce all four species? And if so, then all these species must be botanically renamed as forma of the original species.
I will post some photos in the photos file.

Great! Thank you! I've encountered prickly Banksiae previously. We had a double white in Encino which threw prickly canes regularly. I posted photos of the prickles on the double white page back in 2011 (?).

I have had a private query on the parentage of ‘J. Otto Thilow’. In the hope that more information may come to light, I am replying publicly:
The rule is the seed parent always comes first.
From 1930 Modern Roses 1, page 1:
"Where two parents are shown, the first is usually the seed-bearer".
I have a funny feeling that there was one small country who earlier listed the pollen parent first, but without spending time researching this, I cannot remember which country. Could it have been Holland in the early days? If so, it could explain why Hazlewood in 1928 listed (Souvenir de H. A. Verschuren x Hadley). He explains in his 1928 reference that the main description came from the breeder, and until he knew the rose better, he was adding his own brief comments in italics. I have added a Note to this reference.
A question remains for me - did he get his budwood from each breeder? (There were so many); or did he get his budwood from an agent, or big nursery? Someone told him the parentage he listed.
Most later references show J. Otto Thilow's parentage as (Hadley x Souvenir de H. A. Verschuren) and HMF initially showed this parentage as listed in Modern Roses 1. When I later started adding references the reversed parentage in Hazlewood's catalogues came to light. We have added a Note that there is a discrepancy.
Frank Reader’s parentage suggests that the breeder was popping the pollen of Souvenir de H. A. Verschuren on to more than just J. Otto Thilow.
1927. J. Otto Thilow (Hadley x Souvenir de H. A. Verschuren)
1927 Frank Reader (Golden Ophelia x Souvenir de H. A. Verschuren)
