Description
Gooseneck loosestrife, Lysimachia clethroides, is a fast-growing clump-forming perennial, bearing fresh green, pointed leaves, which turn orange-red briefly before falling in autumn. Its saucer-shaped flowers grow on long, slender arching spikes, reminiscent of a goose neck. It’s perfect for growing in a mixed herbaceous border, where its flowers will attract a wealth of insects.
Grow Lysimachia clethroides in humus-rich, moist soil in full sun or partial shade. It may need support. Cut back after flowering and dig up new shoots to control its spread.
