Hot on the heels of yesterday’s post about ‘Jethro Tull’, the tough new perennial coreopsis with fluted petals, come news of an astonishing array of new coreopsis which are on the way from across the Atlantic.
Click on the picture to see a much enlarged exclusive image of twenty five new coreopsis varieties which are expected to be introduced here over the next few years.
Included in this picture are the Big Bang Series. Unlike ‘Limerock Ruby’ and many other recent coreopsis in unusual colours, varieties in the Big Bang Series are tough as nails and excellent hardy perennials even in climates far colder than ours – they’re hardy down to -20C. They were bred by Darrell Probst, well known as a pioneer breeder of epimediums, in Massachusetts where it’s far far colder than here.
Their background is complicated. The plants in this series are hybrids involving eight different species and have been eight years in the making. They produce a long succession of flowers, on relatively tall plants, around 30in/75cm, with foliage between that of C. verticillata and C. grandiflora in shape.
The first in the series, ‘Full Moon’ (pale yellow), should be on sale here in Britain before too long. If any nurseries are planning to sell them, or anyone spots them on sale, please post a comment below. For the next, ‘Redshift’ (cream with a red ring round the eye), we'll have to wait till next year.
For more on these, and other new coreopsis, take a look at my Transatlantic Plantsman blog.
