ARTHUR LEE NURSERIES 
CENTAUREA. Knapweed - Hardy Cornflower. 
Lovely, free flowering perennials for sunny positions. Easy to grow. Valuable for garden dis¬ 
play and for cutting. 
Culture: All will succeed in good, ordinary soil in sunny borders. Best grown in groups of 
three. Plant in autumn or spring, 8 inches apart; divide and replant every third year. 
Dealbata. (S.L.) 
Large and striking rose-pink flowers. June-July. 2 feet high. 
Macrocephala. (S.L.) 
Large, thistle-like, golden yellow flowers; useful for cutting and showy in borders. July and 
August. 3£ feet high. 
Montana. (S.L.) 
Grows 2 feet high, bearing large violet-blue flowers from July to September. 
Ruthenica. (S.L. ) 
This handsome plant grows about five feet high and bears from July to September, lovely 
lemon-yellow flowers. Fine for the background of the hardy border. 
CERASTIUM. Snow-in-Summer. 
Low-growing perennials, suitable for forming edgings 
to beds or borders, or for bold masses in old walls or 
rock gardens. A plant with neat, silvery foliage and 
white flowers. 
Culture: Ordinary soil and a sunny position is all 
these plants require. 
★ Tomentosum. (S.L.) 
Desirable, low-growing plant with silvery foliage -end 
white flowers in May and June. Suitable for rockery 
or for carpeting dry, sunny spots or covering graves. 
Can also be used effectively in carpet bedding. 
CHEIRANTHUS. Siberian Wallflower. 
Well known hardy plants similar to the Wallflower, for 
growing on the margins of borders and on old walls and 
rock gardens. They are highly esteemed for the de¬ 
licious fragrance of their flowers, also for the fact 
of their flowering so profusely in spring and early 
summer. 
Culture: Plant in ordinary well drained light garden 
soil in full sun. Soil which is heavy or wet will not 
do as plants are easily winter-killed if planted in low, wet ground. Will bloom continuously if 
old flower stems are removed before seed forms. 
*Al I ioni . (S.L. ) 
A beautiful rock plant. Dazzling fiery orange flowers, on stems about a foot high. Best used 
as a biennial as it frequently blooms itself to death, 
CHELONE. Turtle-head or Shell-Flower. 
Hardy, herbaceous perennials, closely allied to the Pentstemon, and of easy culture. The flow¬ 
ers, which are borne on 2 to 3 foot stems, resemble a turtle's head, and are most useful for 
cutting. 
Culture: They succeed well in a moist, rich soil in a sunny border. Best grown in colonies of 
three or more, do well along streams or on borders of ponds. 
Barbatue. (S.L.) 
Spikes two feet long of bright scarlet flowers from June till August. A very effective plant 
for the border. 
CHRYSANTHEMUMS. 
Gorgeous autumn-blooming plants, showy and effective favorites now universally popular, produc¬ 
ing a lavish profusion of colorful flowers just at a time when other plants have been browned by 
early frosts, which do not affect the Chrysanthemums; especially fine for cutting. The blooming 
now extends from late July till late November. 
Culture: They are reasonably hardy if planted in a well-drained position either in the hardy 
border or at the edge of shrubbery. The planting should be done early in the spring, so that 
the plants will have the entire summer to establish themselves; and late in the autumn, after 
they have finished flowering, and the tops have been cut off, they should have a covering of 
leaves or loose litter as a winter protection, but do not cover with manure. Early in the 
spring after danger of severe frosting is over and before any growth starts, the covering should 
be removed. The dates given denotes the flowering period in our nursery; these, of course, may 
differ at various seasons and locations.
