Wisteria sinensis
Chinese wisteria is a vigorous climbing plant that produces spectacular hanging flower clusters in spring. The fragrant purple, blue, or white blooms appear before the foliage has fully unfurled. A mature plant can completely cover walls and pergolas with a lush canopy of leaves.
Plant in humus-rich, well-drained soil in a sheltered, sunny spot. Provide a sturdy support structure or pergola — the branches become remarkably heavy. Water regularly during the first year, then only during prolonged dry spells. Avoid high-nitrogen fertilizers, as they promote leaf growth at the expense of flowers.
Prune twice a year: in July, cut back new shoots to five or six leaves, and in February reduce these same shoots to two or three buds. This encourages flower bud formation for the following season.
Clematis montana
Mountain clematis is a fast-growing climber that becomes smothered in white or pink flowers during May and June. The plant can cover large surfaces in a short time, making it ideal for growing over pergolas, fences, and unsightly walls. The lightly fragrant blooms appear on the previous year's wood.
Lavandula angustifolia
Lavender is a beloved herb with aromatic silver-green foliage and purple-blue flower spikes. This evergreen plant blooms profusely from June to August and is remarkably drought-tolerant, attracting butterflies and bees to the garden.
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.
