OXALIS. 



THE ENGLISH FLOWER GARDEN. OXYTROPIS. 605 



There are other species worthy of a 

 place, especially on very dry sandy soils, 

 and among them are O. Smithi, rosea, 

 Deppei, speciosa, arborea, violacea, versi- 

 color, incarnata, telraphylla, venusta, and 

 corniculata. If a collection, it should be 

 borne in mind that it is very difficult to 

 preserve the correctness of the names, for 

 the minute bulblets become mixed up 



Oxalis Acetosellfi. 



with the earth, and the elasticity of the 

 seed-pots permits the seeds to scatter in 

 all directions. 



O. ADENOPHYLLA. A very beautiful 

 new species from the Andes rivalling and 

 even eclipsing in beauty the better known 

 O. Enneaphylla. The plant is vigorous 

 habited, quite hardy, and grows freely in 

 loamy soils. The flowers are large and 

 coloured rosy-white, and appear in early 

 summer. Rare at present, it is one of 

 the choicest of gems for the rock garden. 

 Height, 4 to 6 inches. Increased by divi- 

 sion of the tubers when dormant. 



O. BOWIEANA. A robust species, form- 

 ing rich masses of leaves, 6 to 9 inches high, 

 and umbels of rose flowers continuously 

 throughout the summer, suitable for warm 

 borders at the foot of a south wall. In 

 cold soils it seldom flowers, but on very 

 sandy, warm, and well-drained soils it 

 flowers abundantly, and where it does 

 well it is one of the most precious of hardy 

 flowers. Division. Cape of Good Hope. 



O. FLORIBUNDA. A free-flowering kind, 

 hardy in all soils ; for months in succes- 

 sion it bears numbers of dark- veined 

 rose-coloured flowers. The white-flowered 

 variety flowers as freely as the rose- 

 coloured form, and both are very useful 

 for the rock garden and for margins of 

 borders, and are easily increased by 

 division. America. 



O. LASIANDRA. A distinct and beau- 

 tiful kind, with large dark green leaves, 

 and in early summer umbels of bright 

 rose-coloured flowers, and useful for warm 

 borders and the rock garden. Mexico. 



O. ENNEAPHYLLA. A lovely plant 

 from the Falkland Islands, producing 

 handsome, pure white, erect, open, bell- 

 shaped flowers from amid pale glaucous 



green foliage. The plant revels in cool 

 rich loam and leaf-mould, and in such 

 flowers well and increases rapidly. Per- 

 fectly hardy and quite amiable. Does 

 not object to thin screening shade. June- 

 July. Increased by tuber division when 

 dormant. O. e. rosea is a pretty variety 

 whose flowers are delicately tinted rose. 



O. LOBATA. A stemless little plant 

 with three deeply-lobed bright green 

 leaflets, and blossoms about | inch across, 

 rich yellow, the centre delicately pencilled 

 with chocolate. A free-flowering bright 

 little plant during sunshine, thriving in 

 warm sandy loam on well-drained borders. 

 Flowers in September-October. Should 

 be planted in the warmest and sunniest 

 position. Chili. 



O. LUTEOLA. One of the prettiest, 

 forming a compact tuft ; the flower-buds 

 inch in length, and a soft creamy-yellow, 

 but when open they are as large as a half- 

 crown, and pure white, shading to yellow 

 towards the centre ; it is not hardy, but 

 in light sandy soil will survive a winter if 

 protected. 



OXYDENDRUM (Sorrel Tree}. A 

 handsome flowering tree reaching a 

 height of over 50 feet in its native 

 country, with rather large fine leaves 

 and many racemes of white flowers ; 

 thriving in our country, at least, on 

 peaty soils, and flowering freely in 

 summer. Ohio and Pennsylvania to 

 Florida, both in mountain and coast 

 lands. The tree is as yet far from 

 common, and the best way at first is 

 to group it with the American shrubs 

 in peaty and free soils. I have 

 planted it in rich leafy soil in most 

 spots in woods, where even small 

 plants so far hold their own among 

 the stoutest sedges. 



OXYTROPIS. Plants of the Pea 



family, nearly allied to Astragalus, the 

 best of which is O. pyrenaica, a dwarf 

 species, with pinnate leaves covered 

 with silky down, barely rising above 

 the ground, the flowers a purplish- 

 lilac, barred with white, and borne in 

 heads of from four to fifteen in early 

 summer. Native of the Pyrenees, 

 rarely in gardens, and increased by 

 seed or division. Plant on well- 

 exposed and bare parts of rock gardens, 

 in firm, sandy, or gravelly soil. O. 

 Halleri has charming, compact flowers, 

 of as deep a blue as that of the Gentians, 

 and proves a manageable plant in 

 the rock garden in deep moist loam. 

 O. uralensis, a dwarf species from 

 the Ural Mountains, has rosy-blue 

 flowers in compact heads, about 

 4 inches high. Other kinds are O.
