The plant's common name refers to the curiously curved spikes of white flowers that appear in
mid-to late summer. One of the few Loosestrifes that have value in the garden, they are a vigorous
growing perennial from Japan, China.
This plant is very adaptable, as it prefers full sun but can grow in shade as well. An upright plant
that spreads by underground rhizomes, which may become invasive under certain conditions. A new cultivar
'Geisha' has variegated leaves and is reputed to be less invasive.
Blooming in mid to late summer, the ½ inch, star-shaped, white flowers are borne on stems that
are about 12 inches tall. The flower heads have a bend or curve in them, creating a whimsical
"gooseneck" appearance. All plants point in the same direction, giving the effect of a
gaggle of geese.
The flowers are hermaphrodite (have both male and female organs) and are pollinated by
insects. Bloom time lasts for about 4 weeks.
Plants form clumps of lance-shaped, olive-green leaves that are yellowish when young. Stems turn a
nice burnished rust color in the fall.
Plant loosestrife in moist, fertile soil that has adequate drainage, do not let them dry out.
They do best when planted in a partially shaded location. Provide a moist soil if the plants are
grown in full sun, otherwise they will tolerate some dryness in partial shade.
These tall perennials are great for mid to back of border, or used a as specimen plant providing
an upright accent of fine texture. It's also an excellent companion for grasses.
Plants can be divided in the spring or fall. Another method of propagation is stem cuttings taken
in the spring or early summer and inserted in sand in a cold frame. Seeds may also be sown.
A word of caution!!!
Loosestrife multiplies by runners under the soil, and can become invasive. If you don't want
gooseneck's taking over your garden, you can plant them in a large pot and sink it into the
ground, or plant in a large raise bed. If it becomes necessary to control plants spread, you can dig out
excessive growth from the edges of the clump. If not kept in bounds it will soon take over and
appear everywhere in the garden.
