Although here in the gardens of the Churchill family we are rightly proud of all of the plants in our collection, at various times of the year, us gardeners will be asked by our visitors for the identity of a core group of recurring plants. During the Summer it might be the Phytolacca americana in the Herbaceous Border with its corn on the cob-like purple fruits. During mid Spring it might be the masses of white flowers of our Exochorda macrantha bushes on the Kitchen Garden banks that catch the eye. And in the depths of Winter the alien seed heads of our recently introduced Cardiocrinum giganteum might be stealing the show. Right now however, the delightful vanillary scent of the yellow flowers of our Elaeagnus ‘Quicksilver’ plants are grabbing a great deal of the horticultural headlines.
Also known as the Silver Bush or Wolf Willow, this Elaeagnus originated in England as a chance hybrid seedling, recognized and named by celebrated British plantsman Roy Lancaster. Roy actually suggests that he thinks it may be a hybrid between Elaeagnus angustifolius and Elaeagnus commutata.
E. ‘Quicksilver’ displays striking silvery foliage on this deciduous, fast-growing shrub. It likes a fertile, well drained soil in full sun, and works well as a specimen plant, or in a shrub border. It can tolerate open or sheltered sites and grows just as well in clay, sandy or loamy soils of virtually any pH. It is considered drought resistant and also thrives in salty coastal conditions, requiring little or no maintenance, although it can reach up to 8ft in height and spread if left completely to its own devices.
‘Quicksilver’ has none of the hazardous spines of E. angustifolia and it is sterile which means that won’t seed itself about like other Elaeagnus shrubs. Although it can sucker itself, it doesn’t do this too vigorously and so doesn’t run around where it isn’t wanted. If I may keep singing its praises, it is also deer-proof, fixes atmospheric nitrogen and can also be pruned back hard to form an attractive silver dome!
Anyway, don’t take my word for all this, come and have a look and a smell for yourselves and enjoy one of the unsung heroes of the gardens of this country…
