A YEAR'S GARDENING 



stagnant; it has beautiful foliage and flowers of a mauve tint. 

 Both may be raised from seed sown in spring. In addition to the 

 above there is 0. verna (Creeping Forget-me-not), a hardy perennial 

 and a charming plant for the Spring Garden. In suitable situations, 

 such as woodland banks, and in a cool, moist soil, it quickly 

 naturalizes itself and runs wild, its white-throated, clear-blue flowers 

 becoming a renewed beauty every spring. 



ONONIS (Rest Harrow). There are three species of this genus 

 which grow wild in this country, and of these 0. arvensis is well worth 

 cultivation on rough banks or in the Wild Garden. It grows in dense 

 tufts, bearing pretty racemes of pink flowers, emd its white variety 

 is equally or even more commendable. Other garden species are 

 0. campestris, rotundifoUa, fruticosa and viscosa. All may be raised 

 from seed or by division. 



ONOSMA. A genus which includes several species with beautiful 

 yellow, purple or white flowers, and among which is 0. taurica (the 

 Golden Drop), an evergreen perennial growing from 6 to 9 inches 

 high, bearing drooping clusters of beU-shaped yellow flowers sweetly 

 scented. It is well suited for the Rock Garden, and should be planted 

 so that its roots may find a firm hold between the stones in gritty 

 loam. It may be raised from seed. 



ORNITHOGALUM [Star of Bethlehem). A genus of bulbous 

 plants of which one — 0. ■pyrenaicum, the Spiked Star of Bethlehem — 

 is a native of this country. 0. umhellatum and 0. nutans have be- 

 come naturalized, and together with 0. pyramidale and 0. latifolium 

 are well worth a place in the garden on grassy banks, etc., or in the 

 Wild Garden. 



OROBUS. A hardy perennial of which some kinds are useful in 

 the garden, such as 0. aurantius, a handsome plant some 18 inches 

 high with flowers of deep yellow, 0. lathyroides, with fine racemes 

 of bright blue flowers, and 0. vernus, which blooms in spring and bears 

 beautiful purple or blue flowers. All may be raised from seed and 

 wUl thrive in ordinary soil. 



OXALIS. Under this name we have several pretty dwarf plants, 

 both perennial and 'annual, which are more or less hardy m our 

 climate, though they all like a dry sandy soil and a warm situation. 

 0. cernua (the Bermuda Buttercup), with handsome yeUow flowers, 

 is a useful kind, while 0. corniculata rubra is valuable as a bedding 

 plant and luxuriates on rough chalky ground. 0. floribunda is a
