112 THE PRACTICAL GARDEN -BOOK 



deep and 8 to 10 inches apart, unless they are to be grown 

 in groups, when they may be planted five or six in the 

 space of 1 foot. Stakes should be furnished each plant 

 to support the flower- spike. When in groups, one stake 

 may be used, setting it in the middle of the circle. 



Gladioli are increased by bulblets formed around the 

 old bulbs (or corms), or they may be grown from seed. The 

 bulblets should be planted in drills in April or May, and 

 will grow to flowering size in one or two years. In the 

 same way, seed sown early in drills, grown through the 

 summer, the little bulbs taken up and stored through the 

 winter and again planted out, will often make bulbs large 

 enough to flower the second year. 



Care should be taken to lift all bulbs before freezing 

 weather, as most varieties are tender. They should be har- 

 vested with the tops on, and laid away in a cool, dry place 

 to ripen. The tops are then cut off and the bulbs stored in 

 a dry place (fit for potatoes, but drier) until wanted the fol- 

 lowing spring. See Bulbs. 



Glaucium, or HORNED POPPY. The kind most 



cultivated (G. luteum) has bright yellow flowers in July and 

 September. The flowers, contrasting with the deep cut 

 glaucous leaves, make a fine effect in the mixed or ribbon 

 border. Seed may be sown in the open ground where 

 wanted. Thin to 12 inches apart. Height 12 to 20 inches. 

 Perennial; but treated as a hardy annual. 



Gloxinia. Choice greenhouse tuberous -rooted 

 perennials, sometimes seen in window gardens, but really 

 not adapted to them. Gloxinias must have a uniform moist 

 and warm atmosphere and protection from the sun. They 

 will not stand abuse or varying conditions. Propagated 

 often by leaf-cuttings, which should give flowering plants 

 in one year. From the leaf, inserted half its length in the 

 soil ( or sometimes only the petiole inserted ) a tuber arises. 

 This tuber, after resting until midwinter or later, is planted 

 and flowering plants soon arise. Gloxinias also grow readily
