PYRETHRUM

P. Useful border plants which are best planted in March (they may be divided at the same time). Pyrethrums grow to about 2 ½ ft., preferring light rather than heavy land. They are grown in huge quantities for cut flowers, but must be cut before the blooms are fully developed. They flower in May and June, a second flush of bloom often appearing in late summer if the plants are cut back after flowering. After about 3 years pyrcthrums tend to deteriorate and should be divided. The doubles are usually less vigorous than the singles. Slugs are very fond of pyrethrums and should be controlled by a metaldehyde preparation.

PYROLA ROTUNDIFOLIA A most attractive plant for a cool, shady position on the rockery or among shrubs like rhododendrons. It belongs to the heather family (Ericaceae) and has glossy, evergreen foliage. The fragrant, white flowers, somewhat like lily-of-the-valley, appear in May and June and are useful for cutting. The plant grows to about 1 ft. and pot-grown specimens seem to move best. Leaf mould and peat should be well mixed with the soil (which should be lime-free) to give a soft, spongy texture. Water freely as necessary in hot summers. Increase by division in early spring.
