 age. 



UMBILICUS. Succulent plants simi- 

 lar to Houseleeks, Spinosus being a very 

 singular-looking plant, with leaves form- 

 ing a rosette something like that of 

 a Sempervivum, each leaf bearing a 

 spine at the apex. The yellow flowers 

 appear early in summer, and form a cylin- 

 drical spike on the top of the flower-stem. 

 It is a good plant for dry sunny spots in 

 the rock-garden, and is tolerably hardy, 

 but slugs destroy it whenever they have 

 a chance. Siberia, China, and Japan. 



U. Chrysanthus is about 4 in. high, 



in rich garden soil, gathers strength from 

 year to year, and when well established is 

 a beautiful object. 



UROSPERMUM. U. Dalechampi is 

 a rather handsome composite from S. 

 Europe ; of dwarf tufted growth, with large 

 heads of lemon-yellow blossoms. It 

 thrives in an open position in any light 

 soil, and is hardy. 



UVULARIA (Bellworf). Graceful 

 perennials allied to Solomon's Seal, bearing 

 yellow blossoms. There are four cultivated 

 species, chinensis, grandiflora, puberula, 

 and sessilifolia. Of these grandiflora is 

 the finest, and the only one worth growing 



Tussilago Farfara variegata (Variegated Coltsfoot). 



with short panicles of yellowish flowers, 

 and suitable for the same positions as 

 spinosus. 



U. Sempervivum forms a rosette-like 

 tuft of succulent leaves, and produces 

 in the second year of its growth a 

 large cluster of pink flowers on a stem 

 about 6 in. in height. It is useful for 

 carpet-bedding, and when used for this 

 purpose the flower-stems must be pinched 

 out. Hardy in the rock-garden or in 

 well-drained soils. Kurdistan. 



UNIOLA. U. latifolia is a handsome 

 perennial Grass from N. America, 2 to 3 ft. 

 high, with a large loose panicle, bearing 

 large flattened spikelets. A clump, placed 



generally. It attains a height of i to 2 

 ft., and its numerous slender stems form 

 a compact tuft, with flowers long and 

 yellow, drooping gracefully, and pretty in 

 early summer. It is a good peat border 

 plant, thriving best in a moist peaty 

 soil. North America, except chinensis.

VACCINIUM ( Whortleberry}. A few 

 of the best Vacciniums may be planted 

 for ornament in peat soil, though 

 none are in the first rank of flow r enng 

 shrubs. One of the most desirable 

 is V. corymbosum, the Blue Berry 



of the North American 



swamps,
