Iris laevigata • Kaempferi or Japanese Iris 
These Irises are included 
among the most magnifi¬ 
cent garden flowers. They 
have a wonderful color- 
range—all the shades of the 
rainbow seem to have been 
gathered in the most fasci¬ 
nating combinations. The 
great size of the flowers is 
noteworthy, often reaching 
the enormous spread of 8 to 
12 inches. Even a single 
plant on the edge of a pool 
brings forth favorable com¬ 
ment. They enjoy almost 
unlimited quantities of fer¬ 
tilizer and swampy ground, 
but any good, well- 
drained soil will encour¬ 
age sturdy growth during 
the dry season. Japanese 
Irises come into bloom 
right after the German 
Iris, and are at their best 
in July.

violet; double.

LOBELIA. Natives of our woods usually found in marshy loca¬

producing massive spikes, 3 to 4 feet tall, of pea-shaped or 
butterfly-like flowers. Should have a place in every garden. 
They require a warm, sheltered position and a moist but 
well-drained light or medium soil, preferably slightly acid. 
Lupines dislike to be moved, so should be planted permanently. 
LYCHNIS. An easily grown, attractive, fine old-fashioned 
flower. The large heads of brilliantly colored flowers liven 
up the border during summer and early autumn. All are 
best in groups in good, ordinary soil. With the exception ol 
Haageana, which does best in partial shade in the rockery, 
they should be grown in a sunny border.

little plant for the rock-garden. About 4 in.

vivid scarlet flowers all summer. Brilliant border plant. 3 ft.

ing profusely in June and July, it is one of the best rosy pink 
flowers at that time of the year. 12 to 15 in. 
LYSIMACHIA Nummularia. Moneywort; Creeping Jenny or 
Charlie. (SL) Prostrate or creeping plants that grow very 
rapidly and bear a profusion of yellow flowers in June and 
July. They are useful in a border, wild garden, along lake 
margins, or as a carpeting for shady places. Prefer moist 
situations and grow well on stream-banks or in any kind of 
waterside plantings. The plants do not require care, except 
to thin them out every two to three years.
