Polemonium - Jacob's Ladder, Charity,
Greek Valerian
Jacob's Ladder is a very
ornamental and graceful flowering plant of early Spring
and Summer. The flowers are blue, or white, flat or
bellshaped, and are borne in spikes; the foliage is
very finely cut, much resembling fern fronds. Polemonium
caeruleum or the Greek Valerian is rather bushy
with long spikes, about 2 feet high, of sky-blue flowers
with golden anthers. P. reptans, a native of
our woods, is dwarf, growing 6 inches or 8 inches high,
with light blue flowers which come into bloom early
in April. P. humile (Richardsonii) is very dainty
and dwarf with small spikes of blue flowers growing
from small rosettes of green, fern-like leaves. All
the varieties bloom from April or May on through August
or September.
UTILIZE. Most of these plants
are splendid for rockeries or in low beds and borders.
The taller ones are used in front of shrubs. Some are
grown as alpine subjects or in wild gardens. The flowers
can be cut, and with their delicate foliage, make up
beautifully for vase or basket work.
GENERAL. Polemoniums are
very easy to grow, thriving best in dry places where
the soil is rich and well-drained and with some shade.
PROPAGATION. These plants
are propagated easily from seed sown in the Fall or
by dividing the plants.
