through the winter. After blooming in the spring cut off the flower 
stalks and allow the plant to ripen. When the leaves turn yellow, lift 
and dry slowly and store in a dry cool place to be replanted in autumn. 
Mature bulbs deteriorate in time, so in order to keep up stock, remove 
small offsets when the bulbs are taken up, and plant in a nursery bed to 
the depth of two or three inches; they will flower the third year. To 
increase a rare variety the Dutch make one or two cross-cuts half way 
through a strong bulb after taking it up, and the next year it makes but 
little growth, but forms a quantity of small bulbs. These are separated 
and planted in nursery beds where they mature the third year. For 
other varieties see Blue, Yellow, Pink and Red Per. May. 
HyvyacintH. Roman (Hyacinthus orientalis, var. albulus), 1 ft., is the 
parent of the Roman Hyacinth. It is more slender and delicate in 
growth than the common Hyacinth, but its culture is the same. 
IcELAND Poppy (Papaver nudicaule). 1-2 ft. A hardy plant with 
ornamental cut leaves forming a low tuft from which rise slender erect 
stalks bearing single and double white flowers. Give a pood garden 
loam and sunny position. They are not very permanent and though 
they are self-sowing to a degree, it is well to sow a little seed each year 
to furnish new seedlings. Vigorous plants should flower for several 
months, and to promote bloom keep the seed-vessels picked closely. 
A light covering during winter is desirable. For other variety see Yellow 
Per. May. 
Irts. German (I. Germanica, var. Silver King and Florentina). 
2 ft. A hardy perennial with sword-shaped leaves, large showy silvery 
white flowers from 4-6 in. across, and thick rootstocks that tend to in- 
crease at the surface of the ground. For this reason the roots must not 
be covered, as they rot readily, and do best in a well drained soil. They 
are propagated by breaking the rootstocks into sections and replanting 
in September, but it takes a year or two to get established, and they 
bloom with more certainty if left undisturbed for three or four years.

LILy OF THE VALLEY (Convallaria majalis). 6 in. A familiar favo- 
rite, with two broad lily leaves, and single stalks of small sweet-scented 
globular flowers. Should have light moist soil, enriched with leaf 
mould. There is an erroneous impression that this plant needs shade, 
and it is too frequently given a cheerless north exposure, or a neglected 
comer of a garden. As it grows shabby after blooming it should not 
have a prominent position, but give it a warm shelter and considerable
