Magnolia × proctoriana - Proctor’s magnolia
Seed collected from willow leaf magnolias (M. salicifolia) in collections produce hybrids with star magnolia (M. stellata), and vice versa. Such hybrids appear to be among the hardiest of the magnolias. Experience in Finland so far only covers a short period but is very promising. The oldest of the shrubs at Mustila has already achieved flowering age.
