According to the Caerhays Estate website: “On 5th April 1897 J.C. Williams and his lifelong friend, P.D. Williams visited Appleshaw and both made significant purchase from Engleheart. Shortly after their visit JCW purchased ‘a whole bed’ of 2 year old daffodil seedlings from Engleheart, including ‘Yellow Princess’.”
There are no photos of "Yellow Princess" in Daffseek.
