FLOWERS OF GARDEN AND GREENHOUSE 
North America (1768). It is but a few inches high, with whorled leaves 
and white flowers, produced in May. There is a variety with double flowers. 
T. aquilegifolium (Columbine-leaved). Feather Columbine. Grows 
to a height of 3 or 4 feet with a slender stem, and glaucous wedge-shaped 
leaflets frequently tinged with purple. Flowers yellowish white, produced 
in masses; stamens purple; May to July. The following varieties are 
also in cultivation:—Yar. atropurpureum has dark purple stems and 
stamens; var. formoswm, also with dark purple stamens, but with dilated 
tips; var. roseum; with rosy-red sepals ; var. rubrum, with red stamens. 
T. Delavayi (Delavay’s). Introduced from China in 1890. It has 
slender stems, 3 feet high, blue-green, much-divided leaves, and loose 
panicles of pale purple flowers; midsummer. A very handsome plant 
for the herbaceous border or rock-garden. 
T. flavum (yellow). Fen Rue. Our second British species has a 
creeping yellow rootstock, stout furrowed stem, 2 to 4 feet; small pale 
yellow sepals and bright yellow anthers; July and August. There are 
several natural varieties, but they are of interest only to botanists. 
T. glaucum (glaucous). A native of South Europe (1798). A robust 
species, 4 or 5 feet high, with blue-green foliage, and yellow flowers in 
an erect dense panicle; June and July. 
T. minus (lesser) is also a native, of similarly, robust habit with 
T. flavum (1 to 4 feet), but with yellow-green sepals, and drooping 
flowers; July and August. There are several good garden varieties, 
such as var. adiantifolium with maidenhair-like leaves. 
T. tuberosum (tuberous). Introduced from Spain 1713. Grows to 
a height of 9 feet, and has large panicles of creamy flowers. 
Culture and Any good soil will suit these plants. A border that is 
Propagation. b ac ] ce( j a shrubbery or wall is a good place for them; 
the taller-growing, of course, being planted in the rear. The coarser 
sorts are useful for the wild garden. T. flavum, T. minus, and its 
varieties, succeed best in chalky or limestone soil. All the species are 
hardy perennials, and may be propagated by division of the rootstock in 
autumn or spring They may also be raised from seed sown in pans in 
a frame in February, or in the open border in April or May. The 
seedlings should be transplanted as soon as they are large enough to be 
handled, or they may be thinned out if in the position they are intended 
to occupy permanently. 
Description or The species figured is the so-called Feathery Colum- 
a bine, Thalictrum aquilegifolium ; and in Fig. 1 a single 
blossom is drawn larger than the natural size, in order to show the 
structure more clearly.
