DIGRAPHIS. THE ENGLISH FLOWER GARDEN. D. PALUSTRIS. 451 



and if there be any to spare, it may be 

 scattered in woods or copses where it is 

 desired to establish the plants. 



DIGRAPHIS (Ribbon Grass). 

 Grasses, of which the Ribbon Grass 

 (D. arundinacea variegata) is the most 

 familiar. Being hardy and perennial, 

 it is valuable for good effect in the 

 flower garden. It should be treated 

 liberally, and renewed by young plants 

 every other year. If it be not desired 

 in the flower garden proper, a few 

 tufts by a back shrubbery will suffice. 

 It grows anywhere. 



Dimorphanthus. See ARALIA. 



DIMORPHOTHECA (Cape Mari- 

 gold) . A hardy annual from the Cape, 

 1 8 inches to 2 feet high ; the flowers of 

 D. pluvialis are white and purplish- 

 violet beneath, expanding in fine 

 weather. Plants from spring-sown 

 seed flower from July to September. 

 It is a bold, free annual, thriving in 

 any good soil and an effective ground 

 plant with the larger flower garden 

 subjects ; alone, however, it is well 

 worth growing. Composites. 



D. AURANTIACA (The Mamaqualand 

 Daisy) is a brilliantly flowered half-hardy 

 annual rather less than a foot high. A 

 sun-lover of the first water. Flower-heads 

 richest golden, the florets having a blackish 

 or crimson zone at their base near the 

 disc. Should be raised in slight warmth 

 in March and April, the seedlings potted 

 singly and planted in the open in May. 

 A raised position on a sunny rock garden 

 in rich soil suits it well. 



DIOSPYROS (Persimmon). Trees 

 from China and Japan which, in our 

 warm counties, appear to be hardy, 

 but do not often produce fruits except 

 in warm soils in the best conditions. 

 One is a native of America, where the 

 fruit is eaten. Others are natives of 

 China. 



DIOSTEA JUNCEA. This rather 

 uncommon shrub presents, when in 

 flower, quite a pleasing appearance. 

 At Glasnevin it forms a densely- 

 branched shrub of about 10 feet high, 

 with green twiggy branches sparingly 

 clothed with tiny, green, ovate leaves. 

 It is at its best towards the end of 

 June, and at that time it carries 

 myriads of sweetly fragrant tubular 

 flowers. The flowers are quite small, 

 being only about inch long, and are 

 of a very pale lilac colour. It is quite 

 hardy. Chili. 



DIOTIS (Sea Cotton-weed). D. mari- 

 tima is a dwarf cottony herb, and 

 sometimes used in the flower garden 



as an edging plant. It is apt to grow 

 rather straggling, and to prevent this 

 it is kept neatly pegged down and cut 

 in well. It should have deep sandy 

 soil. Native of our southern shores. 



DIPELTA FLORIBUNDA. Among 

 the recent discoveries in China are four 

 species of the interesting group called 

 Dipelta. Allied to the Honeysuckles, 

 they are distinct in their fruits, which 

 have attached to them two shield-like 

 discs of the same texture as the wings 

 of Elm seeds. The blossoms are 

 funnel-shaped, i inch to i finches long, 

 dividing at the mouth into five rounded 

 divisions and measuring there i inch 

 across ; they are pale pink, stained 

 with yellow in the throat, and fragrant. 

 It is deciduous and described as 

 being 10 to 15 feet high in a wild 

 state, the bark of the stem and older 

 branches peeling off in thin flakes. 



DIPHYLLEIA CYMOSA. A per- 

 ennial of the Barberry family, about 

 i foot high, having large umbrella-like 

 leaves in pairs. It flowers white, in 

 loose clusters in summer, and suc- 

 ceeded by bluish-black berries. North 

 America, on the borders of rivulets and 

 on mountains, thriving in peat borders 

 and fringes of beds of American plants 

 in moist soil. 



DIPLACUS GLUTINOSUS (Shrubby 

 Mimulus) . A beautiful flowering 

 shrub from California. In the south- 

 west of Britain as hardy as a Fuchsia, 

 starting away well every spring, free 

 from insect pests, and with a long 

 season of beauty. In many gardens, 

 even as far north as Yorkshire, it may 

 be grown well against a wall, and even 

 if destroyed in a hard season increase 

 is so easy that the loss is soon made 

 good. Seed or cuttings. 



Diplopappus. See ASTER. 



DIPSACUS ( Teasel) .Coarse-grow- 

 ing plants, annual or biennial, striking 

 in form, in woods and hedgerows. 

 There are three native species, D. Ful- 

 lonum, pilosus, and sylvestris ; the 

 boldest kind is D. laciniatus, a European 

 species growing 5 to 8 feet high, with 

 large deeply-cut foliage. The seed 

 may be sown in woody places and by 

 freshly broken hedge-banks, where the 

 plants will often perpetuate themselves. 



DIPTERONIA SINENSIS. A little 

 known summer - leafing Chinese tree 

 with beautiful foliage. 



DIRCA PALUSTRIS (Leatherwood). 

 A rough little summer-leafing shrub 

 in our country from N. America, long
