PHILADELPHIA 137 



Gardens yet, although certainly one of the most attractive of mock oranges. 

 t is distinct in its many-flowered inflorescences, combined vith its glossy 

 green leaves, its cupped flowers, and overlapping petals. It is useful in 

 flowering well into July. 



P. LATIFOLIUS, Schrader. 



(P. grandiflorus var. floribundus, Torrey.) 



A robust shrub, 10 to 20 ft. high, as much or more in diameter ; young 

 shoots smooth, green ; the year-old shoots grey, not peeling. Leaves of the 

 barren shoots oval or ovate, broadly tapered or rounded at the base, 

 pointed, sparsely and irregularly toothed ; 2 to 5 ins. long, about half as wide ; 

 dull and almost smooth above, downy beneath ; with three or five prominent 

 veins. Leaves of the flowering twigs smaller. Flowers pure white, if ins. 

 wide, not much scented ; produced in June at the end, and in the uppermost 

 leaf-axils of lateral twigs, usually seven or nine each. Calyx-lobes f in. long, 

 lanceolate, and, like the individual flower-stalks, downy. 



Native of the S.E. United States ; introduced early last century. It is a 

 fine free-flowering shrub, not uncommon in gardens, distinguished chiefly by 

 the year-old wood not peeling, the numerous flowers in each raceme, and the 

 downy calyx. One of the finest and noblest of mock oranges. 



P. LEMOINEI, Hort. 



A deciduous bush of graceful habit, round-topped, and 6 ft. or more high ; 

 young stems covered with pale hairs. The leaves of the strong barren shoots 

 of the year are ovate, with a rounded base, slender-pointed, with usually 

 three to six coarse teeth on either margin about the middle ; I to T.\ ins. 

 long, about half as wide ; dull green and with scattered hairs above, glossy 

 and more hairy beneath. The leaves of the flowering shoots are about I in. 

 long, narrowly ovate, and with few or no teeth. Flowers pure white, very 

 fragrant, I in. across, produced during June in the leaf-axils, and at the end 

 of short lateral branchlets, three to seven on each. 



A hybrid between microphyllus and coronarius raised by Mr Lemoine of 

 Nancy, about 1883. It represents one of the greatest successes ever achieved 

 by the hybridiser's art, being the forerunner in gardens of a new and distinct 

 type of Philadelphus, and the first of a most beautiful race of summer-flowering 

 shrubs. By a system of annual pruning, P. Lemoinei may be kept com- 

 paratively dwarf. The flowers are produced along slender wands (the barren 

 shoots of the previous year), giving wreaths of blossom often \\ to 2 ft. long. To 

 keep the plants dwarf, these should be cut clean out to the base as soon as the 

 flowers are past, leaving only the crowd of young barren shoots springing 

 from the base, and already, at the time of pruning, 6 to 12 ins. long. These 

 will provide the following year's crop of blossom, and if too numerous to 

 develop properly should be thinned. This system of culture gives enormous 

 quantities of flower, and keeps the plants about 3 ft. high, thus rendering 

 them suitable for positions where, left to grow naturally, they might be 

 too big. 



There are numerous varieties now in cultivation of the Lemoinei race ; 

 they have not, however, all the same origin : 



Single. Avalanche, Gerbe de Neige, Fantaisie, Pavilion blanc. 



Double. Boule d'argent, Manteau d'hermine, Virginal. The last has 

 flowers \\ to 2 ins. across, pure white, in dense clusters. Given a first-class 

 certificate" by the Horticultural Society, 2oth June 1911. 



P. Lemoinei, as well as all these varieties, is very quickly and easily 

 increased by cuttings of soft wood in June, placed in brisk bottom heat.
