Euphorbia, Spurge (euphor-bia, after Euphorbus, a physician. 

 Ord. Euphorbiaceae) . A large and varied genus, including annuals 

 and perennials, hardy and tender, herbaceous and shrubby, all with 

 milky juice. Two or three are grown for the greenhouse, notably 

 fulgens (jacquinaeflora), a brilliant evergreen, growing about 3 ft. 

 high, with scarlet flowers in autumn and winter. It thrives in loam 

 in a hothouse, and is propagated by cuttings. Lathyris is the Caper 

 Spurge, and is hardy. 



Eurya (eu-rya, from eurys, large, in allusion to the flowers. Ord. 

 Ternstroemiaceae) . Latifolia variegata is the best of this genus, 

 and is grown for its handsome foliage. It is an evergreen, requiring 

 greenhouse protection. Peat and loam in equal parts suit, with 

 sand. Propagation is by cuttings of mature wood in peaty soil 

 under a bell-glass, 



Eutoca (euto-ca, from eukotos, fruitful, in allusion to the seeding. 

 Ord. Hydrophyllaceae) . The species viscida has blue flowers in 

 summer. For culture, see Annuals. 



Evening Primrose (Oenothera. Ord. Onagrarieae). The Even- 

 ing Primroses comprise both hardy annuals and perennials. For 

 cue culture of the former, see Annuals ; of the latter, Flower Garden 

 Herbaceous plants. See also Oenothera,. 



Evergreens. Plants which hold their leaves throughout the year. 

 Many are valuable as hardy shrubs, these including Hollies, Aucubas, 

 and Laurels. All the principal kinds are dealt with under their 

 own names (see also Flower Garden Shrubs). In pruning, a knife 

 should be used in preference to shears, in order to avoid cutting 

 the leaves. The cuts should be made near the leaves below, so that 

 bare stumps do not show. 



Everlasting Pea (Lathyrus. Ord. Leguminosae) . Beautiful 

 hardy ramblers, suitable for growing against fences and pillars. 

 The typical species is latifolius, now called sylvestris platyphyllus, 

 and has carmine flowers. There is a splendid white variety called 

 White Pearl, which comes true from seed. They enjoy moist, 

 substantial soil. 



Everlastings. The principal " everlasting flowers," such as 

 Helichrysums, Acrocliniums, and Rhodanthes, are dealt with under 

 their own names, or under Annuals. 



Exacurn (ex-acum, from ex, out of, and ago, to drive credited with 

 expelling poison. Ord. Gentianeae). Beautiful plants for a warm
