THE GREEN-HOUSE.

Erica sulphurea, tube-shaped yellow flowers ; plant 

 from 18 ]tp 24 inches high. B. M. 1984. 



December, 



E. vestita rosea, tube-shaped red flowers ; plant up- 

 wards pf 2 feet and a half high. 



All the above species, and a number of others, are 

 figured in Andrews's Heathery, and several of them 

 ill the B. M., B. C, and B. R. Those who live at a 

 distance from the metropolis, may make a selection 

 according to their own taste from the first work ; but 

 those who can have an opportunity of seeing the 

 plants at any of the great London cultivators, will be 

 able to judge more correctly by inspection, especially 

 ias to the hardiness of the plant and its mode of 

 growth. The flowers of heaths are in two grand di- 

 visions, the tube-shaped or long trumpet-like flowers, 

 and the roundish, including the pill-shaped, cup-like 

 and ventricose flowers. In making a selection, a due 

 proportion of each should be fixed on ; a due propor- 

 tion also of red, white, yellow, and purple, of both 

 shapes ; and a due proportion of plants of the dif- 

 ferent heights from 6 to 30 inches. 



The only soil in Avhich heaths will grow is moor 

 earth ; if any substitute can be found, it is in leaf- 

 mould sifted very fine, and mixed with fine sand. 

 Proper earth is obtained by collecting turf from 

 the surface of moory wastes and heathy places, and
