HARDY PERENNIALS: TROLLIUS

These ‘Globe Flowers’ are moisture lovers, but any good garden soil which does not dry out in summer will grow them successfully. The roots are densely fibrous, and the crowns will open out on old plants for division, carrying a portion of the roots. They can be divided and planted in very early spring, or better still in early autumn. Flower buds begin to show long before they actually open in late May, and until late June, they make a luminous display in shades of yellow. T. europaeus superbus along with T. ‘Earliest of AU are the first to flower, the latter being a little deeper in colour and a little taller at 2½ feet. Height is no advantage, and varies somewhat with moisture. T. ‘Goldque/le’ has very large mid-yellow flowers, but T. ‘Fireglobe’ is a shade deeper than T. ‘Orange Princess’. For a pale yellow, T. ‘Canary Bird’ is excellent and as with all these Trollius the rich green foliage is fully complementary. T. ledebouri has less foliage and the flowers are less globular, but such a variety of T. ledebouri ‘Imperial Orange’ is worthy of a place not only because it flowers after

TROLLIUS ‘Goldquelle’ others of the europaeus type have finished, but because of its rich deep colour, enhanced by prominent stamens. This grows to 3 feet flowering from mid-June to early August. These are amongst the plants which benefit from a mulch of compost; peat, or even organic fertiliser can be mixed in beforehand—about a cupful to a bushel, or it can be sprinkled around the plants by itself, prior to applying a mulch about an inch thick. This is an easy alternative to replanting when plants tend to deteriorate with age and has a revitalising effect. In the case of Trollius it can be applied immediately after flowering (or in autumn) and it will not only conserve moisture but often induce a second crop.
