Hardy Heaths. 



arborea, white, May, several varieties. " Brier " pipes are made 

 from the wood. The name has no connection with the hedge 

 Brier, but is a corruption of bruyere, the French for Heath. 



carnea (herbacea), purple, February. 



cinerea, crimson, July, many varieties. 



lusitanica (codonodes), pink, February. 



Mediterranea, purple, spring (Botanical Magazine, t. 471), several 

 varieties.

Erigeron, Fleabane (erig-eron, from er, spring, and geron, old man 

 downy in spring and hoary later. Ord. Compositae). For culture, 

 see Flower Garden Herbaceous plants. The most popular species 

 is aurantiacus, which has orange flowers in July, and grows about a 

 foot high; superbus is a fine variety. Speciosus (syn. Stenactis 

 speciosa), Botanical Magazine, t. 3606, is a good plant. Alpinus 

 semi-barbatus (syn. Roylei) is well worth growing. 



Erinus (eri-nus, from er, spring, because of the early blooming. 

 Ord. Scrophularineae) . The only species grown to any extent is 

 alpinus, which bears magenta flowers in May, and is well adapted for 

 the rockery (see Flower Garden). It likes well-drained, sandy soil 

 and a warm spot. Propagation is by seed. See Botanical Magazine, 

 t. 310. There are white and rose varieties. 



Eritrichium (eritrich-ium, from erion, wool, and thrix, a hair, on 

 account of the woolly hairs. Ord. Boragineae). The species nanum 

 is a useful dwarf plant, giving bright blue yellow-eyed flowers in 

 summer. It may be grown on the rockery (see Flower Garden), if 

 given a pocket of peat and leaf mould, with plenty of grit. Propa- 

 gation is by division in spring. See Botanical Magazine, t. 5853. 



Erodium, Heron's-bill (ero-dium, from erodios, a heron, in allusion 

 to the form of the style and ovaries. Ord. Geraniaceae) . Pretty 

 hardy plants, allied to Geraniums, and suitable for border and 

 rockery (see Flower Garden). They like a light, friable soil, and 

 may be propagated by seeds in spring. Chamaedryoides (syn. 

 Reichardi), with white, rose-veined flowers in summer; Manescavi, 

 with purple flowers in June; and macradenum, violet, June 

 (Botanical Magazine, t. 5665), are all good. 



Eryngium, Sea Holly (eryn-gium, from eryngeon, a name adopted 

 by Pliny. Ord. Umbel liferae). Tall, spreading hardy herbaceous 

 plants, with metallic flowers that, if not beautiful, have quaintness 

 and distinctness. They are not particular as to soil, and are easily 

 propagated by division in spring, or from seeds. The following are 

 the principal kinds: alpinum, blue, 2 ft. (Botanical Magazine, 

 t. 922) ; amethystinum, blue, 2.\ ft. ; maritimum, blue, i ft. ; Oliveri- 

 anum, blue, 2 ft. ; and planum, blue, 3 ft. All flower in summer. 



Erysimum, Hedge Mustard (erys-imum, from eryo, to draw, in 

 allusion to the blistering power. Ord. Cruciferae). See Annuals 

 for culture. Perofskiaum, orange, 18 ins. high, July (Botanical 

 Magazine, t. 3757), is the principal species. It is a biennial, but 

 generally treated as a hardy annual.
