HARDY PERENNIALS: THALICTRUM

The illustration is of only one of several kinds of which can add great charm to the garden. T. dipterearpum likes rich soil and from a comparatively small plant sends up much branched stems to 5 feet which need supporting. It lasts in flower from July to September as does the dwarfer, choicer T. ‘Hewitt’s Double’, which prefers some shade as well as rich moist soil. Several Thalictrums carry large heads of yellow, fluffy flowers and are stronger and more erect. T. angustifolium is one of the best, flowering at 5 feet in June and July. T. aquilegifolium ‘Thundercloud’’ has purplish fluffy heads on 3-4 feet stems, from May to July. These last three are happy in ordinary soil and open positions, though T. rocquebrunianum likes it rich and it is worth applying an occasional mulch to see the blue-green stems grow strongly to 4 feet carrying its charming lavender lilac flowers in June and July. All Thalictrums have delicately pretty leaves and all but the first two mentioned are easy to divide in spring.
