80 HARDY ORNAMENTAL 



rock-garden shrub, of fully 18 inches in height, with arching 

 stems and a plentiful supply of bright flowers during the 

 summer and autumn months. 



G. hispanica. — South-Western Europe, 1759. This 

 species resembles our common Broom, but the branches 

 are not angular. The large, yellow, fragrant flowers 

 appear in July. There is a charming double-flowered 

 variety named G. hispanica flore-pleno. 



G. lusitanica. — Portugal, 1771. This is remarkable 

 for its opposite branches, is of spiny growth, and one of the 

 earliest to appear in flower. 



G. monospeema. — South Europe, 1690. This has white 

 flowers, and is of value as a seaside shrub, and grows 

 well in almost pure sand. A native of the Mediterranean 

 coast. 



G. pilosa. — Greenweed. Europe (Britain). This is a 

 dense, prostrate native species, with bright-yellow blossoms 

 produced freely during May and June. A delightful rock 

 shrub, and one that will succeed well almost in pure 

 gravel. 



G. pbosteata. — Burgundy and Alps of Jura, 1775. A 

 small-growing species suitable for rock gardening, and of 

 spreading bushy growth. Flowers small, but ornamental, 

 and produced in May and June. 



G. eadiata (syn Spartium radiatum). — South Europe, 

 1758. This is a slender-growing shrub, about 18 inches 

 high, with narrow leaflets, and terminal heads of yellow 

 flowers produced in summer. 



G. sagittalis. — South Europe, 1750. With its peculiarly 

 winged and jointed stems, which are of a deep-green colour, 

 this is one of the most distinct forms. The flowers are 

 few but pretty, and with the dwarf habit render the plant 

 an excellent subject for rockwork. 



G. tinctoeia. — Dyers' Greenweed. Europe (Britain), 

 North and West Asia. This is a spineless species, and 

 bears a profusion of yellow flowers from July onwards.
