126 PLANT PROPAGATION 
of hardy herbaceous plants. They are propagated by 
seed sown either in a frame or outdoors in April, and 
by division of the roots in autumn or spring. For 
greenhouse and bedding Geraniums, see Pelargoniums. 
GESNERA.—With these plants propagation is effected 
by planting offsets of the scaly tubers that have 
increased at the roots, also by stem-cuttings inserted in 
pots of sandy peat in a close propagating-case, or by 
detached mature leaves with the petiole inserted and the 
blade incised through the veins and pegged down flat 
on the compost. 
GEuM.—These pretty border flowers are increased by 
seed sown in spring and by division of the roots in 
autumn. 
GiLt1a.—Sow seed in April on a sunny border where 
the plants are intended to flower, and thin out in May 
to 2 inches or 3 inches apart. 
GLapIOLus.—The large and small bulbils, called 
‘* spawn,” produced at the base of the old corms are 
mostly relied on for reproduction, as if planted and 
grown on they flower in one or two years. Seedling's 
raised from seed sown in March generally require to be 
grown on for at least three or four years before reaching 
flowering size. 
GLoriosa.—Offsets produced at the roots, if removed 
carefully when repotting in spring just before growth 
commences, are mostly to be relied on. When seeds 
are used they should be sown singly in small pots of 
sandy compost in January and plunged in bottom heat 
to start them into growth. 
GLoxinia.——Excellent results are obtained by sowing 
a good strain of seed at the end of January or early in 
February. Provide efficient drainage in clean pots,
