lists over two hundred species and varieties that are being grown 
in gardens.* ‘Two of our native Bleeding Hearts—Dicentra 
eximia from Western New York and the Mountains of Virginia, 
and Dicentra formosa from the Pacific Coast—come into bloom 
towards the end of the month. They are similar in appearance, 
both having finely divided foliage, with flowers of deep rose in 
eximia and pale rose in formosa. Both species grow well in shade 
and are tolerant of sunshine. There are colonies of these plants, 
from self-sown seed, all over the rock garden. 
Another native, the interesting Mountain Pachysandra (P. 
procumbens) hailing from the mountains of Kentucky, West Vir- 
ginia and southward, is conspicuous on account of its white fila- 
ments protruding from the inconspicuous brownish sepals. This 
species, unlike its popular relative, the Japanese Pachysandra_ so 
widely used as a ground cover, is seldom seen in gardens. Its 
foliage is dull compared to the oriental species, but its early blos- 
soming makes it worth growing in limited quantities. 
The buttercup-like flowers of Trollius lavus, the North Ameri- 
can representative of the Globeflowers, are not so showy as those 
of the European and Asiatic kinds, but the plant is valuable for 
a wet spot in the garden because of its dwarfness and earliness. 
Toward the middle of the month the “ Pasque Flower ” (Anem- 
one Pulsatilla, Fig. 9) is displaying its rich purple flowers with 
their masses of yellow stamens. Each flower is surrounded by 
a lacy ruff of gray-green, hairy bracts. Its achenes with long 
feathery styles (Fig. 10) are much in evidence after the blossoms 
have fallen, and serve to prolong the period of its attractiveness. 
It is widely distributed in Europe and Siberia in both alpine and 
lowland regions, and is quite amenable to cultivation. 
in the same genus, is the 
—_ 
A close relative, formerly considerec 
well-known Hepatica americana with flowers of white, blue, or 
pink. It is a welcome sight when seen in our rocky woodlands 
and is equally acceptable in the rock garden. Hepatica has simple 
lobed leaves and the circle of bracts close to the flower, while 
Anemone has compound or dissected leaves and the circle of bracts 
further down the flower-stalk.
