I've had this plant a long time; it's bright double red flowers always cheer me up. It is a dwarf growing pelargonium with very dark green foliage. It was introduced in America in 1965, apparently from seed sent there by Frank Read of Norfolk, U.K. to a Mrs James Lumsden of Redondo Beach, California. I have some lovely memories of a short visit I made to Redondo Beach a few years ago.
You may remember the seedlings Sue found when we tidied up her pelargoniums in France about a month ago. She brought them back to the U.K. and here is a photo of them now that she has potted them up individually.
