An albino form of Geranium robertianum, originally thought to have been traced to Sir Charles Isham by A. E. Bowles (1914). It forms masses of low growing white starry flowers, .4 of an inch in diameter with notched petals over deeply divided ferny dark green leaves.

Unlike the rambunctious species G. robertianum, which cannot be recommended for the garden, this plant is relatively well behaved. Be sure to sow seed or transplant seedlings in the spring after all danger of frost is past.
