About red tulip
The lily-flowered red tulips were developed in 1915 and are hybrids of Tulipa retroflexa and the Cotédi group. The curved tulip was bred in 1863 by W. van der Winne, who crossed T. acuminata (T. cornuta) with unknown varieties, and this species, which is free-growing in southern Europe, has proved to be very vigorous as it has retained its elegant flower shape and its narrow, outwardly curving petals over many generations. Lily-flowered tulips are not only beautiful in flower form. They are tall, very colourful, with petals that are translucent, but in some varieties the stems are weak and distort during flowering. ‘Cistulla’, ‘Clarissa’, ‘Kiruna’, ‘Sidonie’, are all very beautiful, newly introduced varieties of this group.
Foster red tulips
Foster red tulips are very varied, most of them with interesting shapes. Some forms have been selected and registered as varieties, such as ‘Defiance’, by C.G. van Tubergen and ‘Madame Lefeber’ by D. Lefeber. Later, C.G. van Tubergen crossed the Foster and Greig tulips with the Mendel and Cottage tulips and developed the varieties ‘Grand Prix’ and ‘Sir Daniel’. Foster’s tulips were crossed with ‘Red Emperor’ to produce ‘Canopus’, ‘Purissima’ and ‘Feu Superbe’. These are early spring tulips. The earliest tulips in the current range are Kaufman hybrids. Central Asian endemic Kaufman’s tulip is a labile species. There are many different forms in the wild. In 1948 the varieties ‘Alfred Cortot’, ‘Josef Kafka’ and ‘Robert Schumann’ were registered. They are dwarf tulips (15-25 cm tall) with large red flowers.
Greig’s red tulips
Greig’s red tulips were introduced to the St Petersburg Botanical Garden in 1873. The brightly coloured flowers have a very interesting shape, reminiscent of Darwin’s tulips. The plants were introduced to Western Europe. Breeders have worked extensively on this species, but the hybrids, like the parent plants, reproduced badly and did not spread. About 80% of these varieties were bred after 1950. Greig-Kaufman hybrids reproduce better.
