THE ENGLISH FLOWER GARDEN. 



I'ACHYSTIMA. 



our country, at least on peaty soils, and 

 flowering freely in summer. Ohio and 

 Pennsylvania to Florida, both in moun- 

 tain 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 

 of such spots. 



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, 



OZOTH AMNUS. O. rosmarinifolius 

 is a neat little evergreen shrub from Tas- 

 mania, almost hardy in the south and coast 

 districts, with small, Rosemary-like leaves, 

 and about the end of summer bearing 

 dense clusters of small white flowers. It 

 thrives in any light soil, and should be 

 planted in an open sunny spot or on a 

 warm bank. Syn., Helichrysum. 



PACHYSANDRA (Mountain Spurge). 

 A little sub-evergreen plant from the 

 rocky woods of North America, 6 to 12 

 inches high, and nearly allied to the 

 Common Box. Its prostrate stems bear 

 deeply toothed leaves of dull green, with 

 small crowded spikes of white or purplish 

 flowers in early spring, when they are 



Ozothamnus rosmarinifolius. 



and borne in heads of irom tour to fifteen 

 in early summer. It is a native of the 

 Pyrenees, rare in gardens, and increased 

 by seed or division. It should be planted 

 on well-exposed and bare parts of rock- 

 gardens, in firm, sandy, or gravelly soil. 

 O. Halleri has charming, compact flowers, 

 of a decided self colour 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 in. high. Other kinds are O. 

 montana, fcetida, strobilacea, campestris, 

 and its several varieties ; all of these 

 are dwarf, and thrive in sandy loamy soil 

 in open spots in the rock-garden. 



much sought by bees. A better plant 

 than P. procumbens, just described, is P. 

 terminates from Japan. This is a true 

 evergreen, with thick glossy leaves of 

 dark green, sometimes variegated, and 

 forms a neat carpet in the rock-garden. 

 Both plants are hardy, and mostly do 

 best in a moist spot and in half-shade, 

 though the Japanese kind will also grow 

 in full sunlight. Easily increased by 

 division. 



PACHYSTIMA. A group of low 

 evergreen shrubs, like the Euonymus, 

 the two best known being from the 

 mountains of North-west America. P. 

 myrsinites, the only kind in our gardens, 

 is I to 2 ft. high, with box-like leaves and 

 inconspicuous reddish flowers followed
