EPIGAEA REPENS.--Ground Laurel, or New England Mayflower. Northern United States, 1736. This is, perhaps, in so far as stature is concerned, hardly worthy of a place in our list, yet it is such a pretty and useful shrub, though rarely rising more than 6 inches from the ground, that we cannot well pass it over. For planting beneath Pine or other trees, where it can spread about at will, this prostrate shrub is most at home. There it enlivens the spot with its pretty evergreen foliage, and sweet-scented, white or pinky flowers. It is quite hardy. ERCILLA. ERCILLA SPICATA (_syn Bridgesia spicata_).--Chili, 1840. A small-growing, half-climbing shrub, with leathery, deep green leaves, and inconspicuous flowers. Hailing from Chili, it is not very hardy, but given the protection of a wall, or planted against a tree-stump, it soon forms a neat mass of evergreen foliage. ERICA. ERICA CARNEA.--South Europe, 1763. This is one of the most beautiful and desirable of hardy Heaths, on account of the richly-coloured flowers and early season at which they are produced. In the typical species the flowers are pink or flesh-coloured, and produced in January and February. It is a dwarf, compact growing species, with bright green foliage. There is a form with pure white flowers, named E. carnea alba, or E. herbacea, but although distinct and beautiful, it is not of so robust growth as the parent. E. CILIARIS.--A pretty native species, with ciliate glandular leaves, and racemes of highly-coloured, rosy flowers. Found in Dorsetshire and Cornwall. E. CINEREA,--Gray-leaved Heath. In this species, also a native of Britain, the flowers are of a reddish-purple colour, and borne in dense terminal racemes. There are numerous varieties, including a white-flowered E. cinerea alba; E. cinerea atro-purpurea, bearing dark purple flowers; E. cinerea atro-sanguinea, dark red flowers; E. cinerea coccinea, scarlet; E. cinerea purpurea, purple flowers; and E. cinerea rosea, with deep rose-coloured flowers. E. MEDITERRANEA.--Mediterranean Heath. Portugal, 1648. This is a robust-growing species, of rather erect habit, and often attaining to fully a yard in height. Flowers abundantly produced, and of a pretty pinky hue. Of this there are several varieties, the following being best known: E. mediterranea hibernica, found in Ireland; E. mediterranea alba, with white flowers; E. mediterranea nana, of very dwarf growth; and E. mediterranea rubra, with showy, deep red flowers. E. SCOPARIA and E. ERECTA are desirable species, the former bearing greenish flowers, and the latter of decidedly upright growth. E. TETRALIX.--Cross-leaved Heath. A native species of low, and bushy growth, with close umbels or terminal clusters of pretty pinky flowers. The varieties of this most worthy of notice are E. Tetralix alba, white flowered; E. Tetralix Mackiana, crimson flowered; E. Tetralix rubra, deep red flowers; and E. Tetralixbicolor, with parti-coloured flowers.
