Faassen who developed first hybrids; this species a hybrid of N. racemosa and N. nepetella, even though listed by RHS as cultivar of racemosa, and sometimes listed without a species but being in the Faassenii group of the genus; this cultivar, introduced by Four Seasons nursery of Norwich England in 1988, was found in an Irish garden in the 1970's by Mrs. Patricia Taylor and named for a garden there, and does not refer to the plant size.
