Using the research material grown during his study of hardy geraniums, Peter Yeo went on to make several selections of gardenworthy plants. This includes Geranium pratense ‘Brookside’ which was named after the house in which the Garden’s offices were based during his time at the Garden. (A large part of the Garden’s staff are now once again based in this building, which is adjacent to the main entrance.)
A hybrid between G. clarkei and G. pratense, this worthy border plant has attractive cut foliage and violet blue flowers with fine reddish veins and a whiite centre. Flowering in June and July and growing to a height of up to 60 cms, it benefits from the flowering stems being cut back as the flowers fade to encourage a second flush later in the season. It can be seen in the beds alongside Lynch Walk and those near the main entrance and 1, Brookside as well as in the Geranium national collection beds near the Rock Garden. It holds an RHS Award of Garden Merit.
