Rh and E. Characias, 2 to 3 ft., with green bracts, are fine plants for rockwork or sheltered, corners.

Ferula.—Gigantic umbelliferous plants, with magnificent foliage, adapted for shrubbery borders or open spots on lawns. They have thick fleshy roots, deeply penetrating, and therefore requiring deep soil, which should be of a light or sandy character. F. communis, F. glauca, and F. tingitana, the last with glossy lozenge-shaped leaflets, grow 8 to 10 ft. high; F. Ferulago, with more finely cut leaves, grows 5 to 6 ft. high. They flower in early spring, and all have a fine appearance when in bloom, on account of their large showy umbels of yellow flowers.

Fritillaria.—A large genus of liliaceous bulbs, the best known of which is the crown imperial (F. imperialis) and the snake’s head (F. Meleagris). There are many charming species grown, such as aurea, pudica, recurva, sewerzowi, askabadensis, &c.

Funkia.—Pretty liliaceous plants, with simple conspicuously longitudinal-ribbed leaves, the racemose flowers funnel-shaped and deflexed. F. Sieboldiana, 1 ft., has lilac flowers; F. grandiflora, 18 in., is white and fragrant; F. coerulea, 18 in., is violet-blue; F. albo-marginata, 15 in., has the leaves edged with white, and the flowers lilac.
