MaintenanceOf all of the Geraniums that I have grown this seems to open up and fall apart the most. After flowering cut back hard to encourage a new flush of growth.
Propagationdivision
Cultivar OriginA hybrid cross between G. himalayense and G. pratense. Named after AT Johnson.
Misc FactsAlthough this plant has a good flush of flowers, it gets very untidy after the bloom period. If you can live with this fact and are willing to cut it back, it is a good plant.
Author's NotesWhen I had my nursery I remember this was a "hot" new plant and I paid an absorbent amount for the divisions. Now has been superseded by many new cultivars. Still growing in my garden for over 25 years.
