ms up fully eighteen inches, blooming more or less all
summer. _G. coccineum_, with scarlet flowers, and _G. Hederichi_,
are both good.

_Hesperis matronalis_--Rocket

An admirable plant for use where most other plants would fail. It does
fairly well in semi-shady places, at base of shrubs and in between them
in open spots. Plants grow three to four feet tall, of bushy form when
treated well, bearing pinkish flowers in June and July. There is a
white form.

_Hemerocalis_--Yellow Day Lily

All are good, strong growers with narrow iris-like foliage, producing
flowers in tones of yellow. _H. flava_, the sweet-scented, deep
lemon-yellow-flowered form, is the best and must not be confounded with
the coarser-flowered _H. fulva_, the tawny day lily.

_Hibiscus_--Mallow

All the mallows are good, from the "crimson eye" to the new mallow
marvels, moderately late, upright-growing and hardy. The colors run
from pure white to pinks and reds.

_Inula ensifolia_

A low-growing very hardy plant bearing freely yellow daisy-like
flowers, always presenting a neat appearance.

Hollyhocks

On account of the prevailing hollyhock disease--a disease of the
foliage hard to combat--it is best to grow one-year-old plants, as they
are less affected than the older ones. The singles are the most
charming.

Iris--Fleur-de-lis

This is a large group, from the bulbous Spanish and English iris, which
bloom in June and then die down to reappear next season, and may
therefore be planted in open spaces between other plants, to the
magnificent Japanese iris, _I. Kaempferi_. This latter one is somewhat
fickle and does not last long. The best for general planting are the
German, _cristata_, _pumilla_ and _Sibirica_ varieties. _Pallida
Dalmatica_ is exceedingly fine.

through August, September and October. Beware of the magenta colorings]

_Lysimachia clethroides_--Loose-strife

An excellent plant in damp soils.

_Paeonia_--Peony

Every one should have them, including the early-flowering red _P.
officinalis_, and the later ones. Try a few tree peonies--_P. Moutan_.
They are grafted on the ordinary form, so destroy all suckers that come
from below the union.

Phlox

The tall-growing hardy phlox should be in all gardens. It is permanent
if taken up every three years and divided. Strong "cutting" plants give
the finest blooms. Avoid magenta colors. Th
