Corydalis lutea
Yellow corydalis is a charming, long-flowering perennial with fern-like light green foliage and clusters of yellow, spurred flowers. From May to October it continually produces new blooms. The plant self-seeds effortlessly in wall crevices and between stones.
Plant in partial shade in well-drained soil. Tolerates dry spells, provided they are not too prolonged. The plant loves to establish itself in wall joints and rock gardens. Feeding is rarely needed — overly rich soil reduces flowering.
Pruning is seldom necessary. Remove excess seedlings if the plant spreads too vigorously. Optionally cut back old foliage after summer to encourage fresh growth.
Helleborus orientalis
The Lenten Rose is one of the first bloomers of the garden year, with saucer-shaped flowers in purple, pink or white appearing as early as February. The evergreen, palmate foliage forms attractive clumps that remain decorative year-round. The plant is a valuable early nectar source for bees.
Ajuga reptans
Bugleweed is a robust ground cover that spreads rapidly through runners. From April to June, dense spikes of blue-purple flowers rise above the dark green, glossy foliage. The plant is evergreen and forms a continuous carpet within a single growing season.
Alchemilla mollis
Lady's Mantle is a reliable perennial treasured for its beautiful, scalloped leaves that catch dewdrops like tiny pearls. From June to July, clouds of delicate yellow-green flowers appear, making excellent cut flowers. The plant forms attractive, rounded clumps and works beautifully as edging.
