* Incarvillea Delavayi 
HIBISCUS - Mallow 
About one hundred and fifty to two hundred species are known, some 
annual, others perennial or as shrubs. We are dealing here only with 
the Giant Mallow of recent introduction which is a tall plant about 
three to four feet high with immense white, pink or red, hollyhock-like 
flowers, freely produced during the summer. 
Culture. A rich, moist, well drained soil suits them best. Best planted as 
single specimens in full sun in the border or in groups of three or more 
on the lawn. Plant in fall or spring, 24 inches apart. 
Giant-Flowering Mallows 
A wonderfully improved form of our greatly admired native Marshmallow 
or Rosemallow. We supply 3-yr. flowering plants. 
Red, Pink or White in Separate Colors 
Three $1.45, Doz. $4.75, 100 $25.00

HOSTA (See Funkia, page 36). 
IBERIS - Candytuft 
Although these plants are perhaps more generally grown in the rockery, 
they are equally appropriate subjects for the margins of herbaceous 
borders or as edging to garden walks. When in flower in spring and 
covered with a mass of snow-white blossoms, they add considerably to 
the attractions of the garden. They are of shrubby growth, with dark 
green, evergreen foliage. 
Culture. Grow in good, ordinary soil. Plant in fall or spring, 6 inches 
apart. When plants become straggly, trim them directly after flowering. 
*Little Gem (true form) Three $1.50, Doz. $5.00, 100 $30.00 
Dwarf, pure white flowers in June. Its uniform, neat habit makes it one 
of our best compact low formal edging plants; perfectly hardy. There 
is nothing much better for edging small flower beds. 
**Sempervirens Three $1.45, Doz. $4.75, 100 $25.00 
Covered with a sheet of white flowers in spring, completely covering its 
rich dark green foliage; a particularly fine plant for the border. Does 
well in light shade and therefore excellent as a ground cover in front of 
shrubs. May be used for edging to parks or walks. Little Gem, however, 
is more formal and upright for these purposes. 
*Snowflake Three $1.50, Doz. $5.00, 100 $30.00 
In growth more compact than Sempervirens, the flowers are fully three 
times as large, covering the plant completely when in bloom. A charm- 
ing plant for edging walks or flower beds, as well as in the rock garden. 
Being all grown from cuttings, the effect created is beautifully uniform.

INCARVILLEA - Trumpet-Flower 
Fleshy rooted perennials of striking beauty. They have handsome, coarse- 
ly toothed or pinnate leaves, and showy, trumpet-shaped flowers borne in 
terminal racemes. Choice plants for the sunny border. Grandiflora bre- 
vipes is a lovely thing in the rock garden, not growing over 4 to 6 
inches tall. 
Culture. All require a deep, rich, loamy and well drained soil and a 
sunny position. Not suitable for heavy or damp soils. Best planted in 
March and grown in groups of six or more. Plant 8 inches apart.

crimson-purple flowers. A splendid rock plant, easily grown.

(Evansia.) A dainty native creeping species, only 3 inches in height;

IRIS SPURIA 
(Finest Iris for cut flowers.) These are so different from all other 
Beardless Species and Hybrids as to deserve a separate sub-division. The 
flowers are quite unlike all other Irises, and are very artistic, making 
exquisite cut flowers for which purpose they are used extensively by 
florists. They are hardy anywhere. While not indispensable to their 
success, they prefer a moist spot and make a most imposing effect in 
the garden.

FOOD FOR THOUGHT 
As Well as For Your Flowers 
Plants, anything that grows in the soil, are exactly the same in their 
food needs as humans. There are plenty of what might be called the 
shot-in-the-arm kinds of ready mixed fertilizers. But, they are mostly 
only stimulants. 
What your plants need is a balanced organic food. Not just a stimu- 
lant. They need one containing in right amounts, those things that 
make plenty of strong roots, produce good sturdy stalks, thrifty foliage 
and an abundance of good sized blooms. 
That’s exactly the kind of Plant Food we use at Wayside. Much of 
our success in growing such unfailingly fine plants is due to it, 
What it has done and is doing for our 600 miles of plants, it will 
do for your garden.
