ACHILLEA - Milfoil or Yarrow 
Showy rock and border perennials, some of which are valuable for cut 
flowers. Some have silvery and others elegantly cut foliage, which adds 
considerably to the beauty of the plants. 
Culture. All will succeed in any good, ordinary soil in sunny borders. A 
too rich soil should be avoided. Plant in autumn or early spring, 8 to 
10 inches apart. As nearly all grow freely, it is advisable to lift, divide, 
and replant every third year. Directly after the plants cease flowering, 
cut the shocts back.

Ptarmica, Snowball Three $1.45, Doz. $4.75, 100 $25.00

cut flower. 
Taggetea Three $1.45, Doz. $4.75, 100 $25.00 
A splendid plant for hot dry sunny places. Does well in the most in- 
different soils. The pale yellow flowers grow on 18-inch stems which

ACONITUM - Monkshood 
Lovely late summer and autumn flowering perennials of stately growth, 
particularly adapted for shady or half-shady borders.

moist. They are especially suitable for shady or semi-shady position, and 
are best grown in groups of three or more. Plant in autumn or very 
early spring, 6 to 8 inches apart. They display their beauty to the best 
advantage when they have become well established and formed large 
clumps. It is therefore advisable not to disturb the plants frequently. 
Fischeri Three $1.45, Doz. $4.75, 100 $25.00

rose-pink flowers. Suitable for the rock garden or for grouping on the

light shade. Plant in spring. Protect in cold regions. 
Umbellatus Dormant roots, Each $1.00, Doz. $10.00

Achillea, Snowball 
ALYSSUM - Madwort; Basket of Gold 
Attractive early-flowering perennials, suitable for growing on the mar- 
gins of sunny borders or in sunny places in the rock wall or rock garden. 
Culture. The varieties offered will succeed in any good, ordinary soil 
which must be thoroughly drained. They are best grown in groups of 
three or more in the rock garden, or as edgings to beds. Plant in fall 
or spring, about 6 to 8 inches apart. Alyssum Saxatile is frequently used 
for carpeting beds planted with spring bulbs, and is very effective for 
that purpose.
