- Daphne × burkwoodii is from a cross between D. cneorum and D. caucasica, crosses were made independently by the brothers Albert and Alfred Burkwood. Some say that the crosses resulted in only three seeds and that only two of seedlings survived, each giving rise to a cultivar, one named, ultimately, ‘Arthur Burkwood’ and the other ‘Sumerset’. Alice Coats (1992, p.71) states that each brother "selected the best of the resultant seedlings", and that Alfred's plant was distributed by company under the name of Daphne ‘Sumerset’ and that Albert's plant was distributed by the frim of Burkwood and Skipwith as D. × burkwood, presumably this later became known as ‘Arthur Burkwood’.
- ‘Arthur Burkwood’ --- broad shrub to over 3 ft (~1 m) high, leaves to 3 cm long × 0.75 cm wide, linear-oblanceolate, tips apiculate, flowers white ageing to deep pink.
