696 ZENOBIA ZIZYPHUS 



duced in 1801. This beautiful shrub, whose pendent blossoms resemble 

 large lily-of-the-valley flowers, is, after long neglect, becoming more 

 frequent in gardens. It can be forced into bloom early (it flowers 

 naturally in June and July), and potted plants profusely in flower may be 

 seen at most Spring Shows. It needs a peaty soil, or a light loamy one, 

 with which decayed leaves have been freely incorporated. It can be 

 propagated by cuttings of half-ripened wood placed in gentle heat about 

 July, or by seeds treated as advised for rhododendrons. The flowering 

 part of the shoot, from beneath which the young shoots spring, should be 

 cut off as soon as the flowers are faded, if seed is not required. 



Var. QUERCIFOLIA has the leaf-margins set with shallow wavy lobes. 

 A curiosity. 



Z. PULVERULENTA, Pollard (Z. speciosa var. pulverulenta, Nicholson ; 

 Andromeda pulverulenta, Bartrani). For garden purposes it is more 

 convenient to treat this as a species, as some authors do, but in all 

 essential characters it is identical with Z. speciosa. Beautiful as that 

 shrub is, this is still more lovely. It is easily distinguished from it by 

 having very glaucous foliage and young shoots. It blossoms with even 

 greater freedom, and the mixture of young, blue-white leaves and pure 

 white flowers is very attractive. Native of the same areas as Z. speciosa. 



ZIZYPHUS SATIVA, Gaertner. JUJUBE. RHAMNACE^E. 



(Z. vulgaris, Lamarck.") 



A small deciduous tree up to 30 ft. high, with glabrous, spiny 

 branches; spines in pairs, the longer one up to ij ins. long, straight, the 

 shorter one decurved. Leaves alternate, ovate to ovate-lanceolate, 

 shallowly round-toothed, blunt or rounded at the apex, smooth, or downy 

 only on the veins beneath ; three-veined at the base. Flowers less than 

 -J in. across, yellowish, borne two or three together on short stalks in the 

 leaf-axils. Fruit fleshy and rather like a small plum, roundish egg-shaped, 

 J to i in. long, dark red, or almost black when ripe. 



This interesting tree is not very hardy. At Kew it has lived outside 

 for several years, but does not grow vigorously ; it is worth trying in the 

 milder counties. The fruits have a pleasant acid taste when fresh, but 

 are more agreeable when dried ; they are commonly eaten in both states 

 in the Mediterranean region. The species now extends, both wild and 

 cultivated, from S.E. Europe to Afghanistan, China, and Japan, but may 

 have become naturalised in Europe. It was in cultivation in England in 

 1640, but its tenderness has always kept it rare. The only other hardy 

 shrub with which it is likely to be confused is Paliurus australis, which it 

 resembles in leaves and spines ; but the larger and prettier flowers of the 

 Paliurus, produced in short branched umbels, and especially the dry, flat, 

 winged fruits, are very distinct
