of the whiteness of their foliage. They grow in any 
well-drained garden soil, and may be increased by 
division in spring, or from seeds. The most useful 
kinds are cashmeriana, 2 feet high, with woolly white 
stems and leaves, and lilac-purple 2-lipped flowers ; 
viscosa, 3 to 5 feet high, whitish, with numerous yellow 
flowers. The Jerusalem Sage (P. fruticosa ) is a 
shrubby plant 2 to 4 feet high, with woolly white 
leaves, and masses of yellow flowers. It may be 
increased by seeds, or cuttings of the young shoots.

Phloxes, but they are now overshadowed by the lovely 
garden forms which have been developed from P. 
maculata, P. paniculata, and P. suffruticosa. They 
flourish in any good well-drained garden soil that has 
been deeply dug and enriched with well-decayed 
manure. The simplest way to increase them is by 
division of the rootstocks in spring. Cuttings of the 
young shoots will also root freely in sandy soil in a 
greenhouse or close frame. Seeds may also be sown in 
.spring. As to colour there is a good range from pure 
white through pink, rose, lilac, magenta, salmon, 
purple, crimson, and almost scarlet — some forms 
being quite pure, while others have a distinct colour in 
the centre or “ eye.” In trade catalogues hundreds of 
varieties are named and described, and the reader may 
select his favourite colours from them. (Plate 31.)

pale lilac or bluish, or white in the form called alba; 
ovata, reddish-purple ; procumbens, lilac ; pilosa, with
