grow about two
feet high and bloom all summer if not allowed to go to seed, but seldom
last over the third year.

Delphiniums

Have already been discussed. All the named varieties are good,
especially Belladonna. See page 26.

_Dictamnus_--Gas Plant

Fully described on page 32.

_Digitalis_--Foxglove

The form usually grown is treated as a biennial, and with me, must be
coldframed the first year. _Ambigua_ or _grandiflora_ is a perennial
having pleasing pale yellow flowers, and is a comparatively long-lived
plant.

_Echinops_--Globe Thistle

This is a tall, interesting plant with foliage somewhat like a thistle.
_E. Ritro_ is the best. Its peculiar flower head consists of a ball
about an inch and a half in diameter, from which spring, in close array
all over the ball, minute flowers of a deep metallic blue.

_Eryngium_--Sea Holly

A plant somewhat similar in appearance to the _Echinops_, but smaller
in all its parts. _E. amethystinum_ is the best, having small globular
flower heads of an amethystine blue color, this color also extending
quite a way down the flower stems.

_Eupatorium_--Thoroughwort

Two forms are in the market--_E. ageratoides_, bearing numerous small
white flowers in late summer, and _E. coelestinum_, with light blue
flowers similar to the ageratum. Both are good.

_Funkia_--Plantain Lily--Broad-leaf Day Lily

I consider _F. subcordata grandiflora_ the best of this group. In time
a single plant, if not crowded, will make a mound of green foliage,
looking as if an inverted bushel basket were shingled with broad
overlapping foliage, above which, in August, spring pure white,
sweet-scented lily-like flowers. It will stand partial shade. If
planted in groups they should be placed two and a half to three feet
apart. Tulips may be planted between them.

_Gaillardia_--Blanket Flower

The perennial forms produce much handsomer flowers than do the annuals.
All of our garden perennial forms, including _grandiflora_, are
varieties of _G. aristata_, and, being natives of Texas, are not always
hardy in the Northern States.--See page 4 in the text. It is a rather
sprawling plant, growing naturally some two feet high, and hard to
stake, but may be pegged down. Use common long hairpins. It requires an
open situation in full sun, and thrives best in a sandy soil, well
drained.

_Geum_--Avens

Quite a hardy border plant, rather low in its foliage, but throwing its
flower ste
