S. x christii - description

S. x christii was first described by Wolf in 1889.

This is a natural hybrid between S. grandiflorum and S. montanum.

It is found in Switzerland and northern Italy, where it occurs in differing forms, varying in size from that of one parent to that of the other.

Rosettes are usually deep green and densely pubescent.

Flower colour is also variable, although the petals tend to be yellow or at least yellow near the tips.
