Stonebreak Family 353 
oak-leaf-like foliage (our to eight inches), with rich autumn tints, 
and pinkish-white flowers (June) turning purple. 
HT. vestita pubescens Maxim. (123), a shrub from China, with slender 
branches (four to five feet), is recommended for its hardiness (half 
hardy in Ottawa), and its early blooming (June) in broad cymes of 
flowers, white changing to pink, and large leaves (four to eight inches). 
Among the less hardy ones, which 1equire protection in winter, are: 
HT. hortensis Smith (124), and a number of varieties, especially 
HT, Otaksa Maxim (124a), from China, with variable color of flowers, 
which appear in July in large balls, and change hues (white to blue and 
pink) during the season; are good tub plants on piazzas and in formal 
gardens. 
H. Thunbergt 8. & Z. (serrata) (125), a dwarf, from Japan, with 
blue or rose-colored flowers in cymes. 
Deutzia. A genus from Asia, of tall, medium, and low, sturdy shrubs 
of rather stiff habit; more or less hardy, and very ornamental, with 
dense, luxuriant foliage, and showy, white to purplish flowers in bunches, 
mostly from the axils of the leaves. ‘They thrive in almost any soil 
and are easily cultivated. 
D. scabra Thunb. (126), a native from China and Japan (six to eight 
feet), with rough, stiff, rigid foliage; forms the basis of a number of 
varieties, which are superior to the type in their flowers, of which the 
best, D. flore pleno (1242), Pride of Rochester (sometimes referred to 
crenaia), is also the largest as well as the best in form, with large, double, 
pure white, rather early flowers (May, June). D. candidissima (1260), 
has the double white flowers in rosettes. 
D. crenata 8. & Z. purpurea (127) and D. Waterert (127a) have 
flowers of a pink shade, the first single, the second double. 
D. parviflora Bonge. (128), the hardiest, from China (four to six 
feet), is the earliest bloomer (April), with creamy-white, lilac-like 
bunches of flowers, and rather roughened foliage, of better form than 
the preceding. 
D. gracilis Sieb. & Zucc (129), from Japan, a dwarf (one to four 
feet) of rounded form, with slender, arching branches and early (May), 
very luxuriant inflorescence of delicate, small, white flowers in graceful, 
nodding racemes; is the best for borders, for facings, and small places. 
D. Lemoineit Hort. (130), cross between D. gracilis and D. parvi- 
flora, another dwarf, with large foliage (two or three inches), is said to 
excel the foregoing in vigor and showiness.
