In the 1960's, the American hybridiser, Frances Hartsook bred a number of Uniques that would be able to cope with the heat of a desert area of Mexico, where she was living at the time. She used various regals and Old Scarlet Unique in her crosses. Sadly Miss Hartsook seems to have lost her original records with the parentage of her Uniques.
Last weekend, on the way home from a short stay in Lincoln, I visited The Herb Nursery, a small nursery in Rutland. They have a collection of pelargoniums, as well as herbs and many other garden shrubs and perennials. Naturally, the pelargoniums where what I went to see. I was not disappointed and I can highly recommend this small neat and charming nursery. All the plants were well grown and all looked very healthy. Rollison's Unique was one of the plants I came home with, as well as three others. Originally introduced in the UK c.1880 and supposedly registered in 1835.
