produce a charming- effect when in flower. PlaOt in October 
or March. Increased readily by division in spring. 
Cerinthe (Honeywort). — Half-hardy annuals, natives of 
Europe and members of the Borage family (Boraginaceae). 
They are particularly showy plants, and consequently are only 
worth growing in large gardens where there is plenty of room. 
The best known species are: C. aspera, yellow, July, i to 2ft. ; 
C. minor, yellow, June, 12 to i8in. ; C. retorta, yellow and 
violet, July, 12 to i8in. Sow in patches in sunny borders in 
April, and thin out the seedlings later to 8 or 12m. apart. 
Chsenostoma.— Perennial herbs, natives of the Cape 
and members of the Foxglove order (Scrophulariaceae). The 
species named below are only suitable for large gardens. 
They are: C. cordata, white, June, 12 to i8in. ; C. fastigiata, 
rose or white, J'une, 6 to gin. ; C. hispida, lilac or white, July, 
3 to 6in. ; C. linifolia, yellow, Sept., ift. ; and C. polyantha, 
lilac and yellow, July, 4m. Though perennials, they require 
to be treated as half-hardv annuals, sowing the seeds in heat 
in March, transplanting the seedlings later into boxes, harden- 
ing off in May, and planting out in sunny borders in May. 
Cuttings may be taken from the plants in August, and struck 
and wintered in a greenhouse. 
Cheiranthus (Wallflower). — The wallflower belongs to 
the Nat. Order Cruciferae, and is one of the oldest, sweetest, and 
most popular of all garden flowers. Poets have sung its 
praises for ages, and although not a native of Britain, it has 
naturalised itself freely on hoary old ruins and modern railway 
banks, and made itself quite at home. The wallflower (C. 
Cheiri) has been vastly improved of late years, and now we 
have a wonderfully varied strain of this popular flower. There 
are single and double varieties, but the former are by far the 
prettiest. A few of the best known strains of singles are : 
Harbinger, crimson ; Belvoir Castle, yellow ; Ruby Gem, ruby 
violet; Eastern Queen, chamois to salmon-red; Purple Queen, 
ruby; and Primrose Dame, lemon-yellow. Of the double- 
flowered, the Double German is an excellent strain, yielding 
dwarf plants and a profusion of pretty spikes of deliciously 
fragrant flowers. Most seedsmen have their own strains of 
doubles also. The seeds of both the single and double kinds 
should be sown outdoors in April, and the seedlings trans- 
planted, 4 to 6in. apart, in a nursery bed, as soon as the third 
leaf forms. When planting remove the point of the tap-root. 
The wallflower loves lime, and it is a good practice to scatter a 
little lime over the seed bed and the nursery bed before sowing 
or planting. Firm soil is necessary to grow bushy plants. In
