Clematis montana 'Giant Star' is a robust deciduous climber known for its impressive display of large, semi-double flowers that bloom in soft pink hues, accented by delicate notes of vanilla. This variety is particularly well-suited for adorning expansive structures, as it produces a stunning array of blossoms in spring, creating a vibrant and inviting atmosphere.
The plant features a climbing habit characterized by twining leaf stalks and lush dark green foliage, with young leaves exhibiting a subtle purple tint. Each flower measures approximately 10 cm (4 in) across, showcasing a blend of soft pink and pale salmon tones, complemented by yellow anthers. Blooming occurs from April to May, attracting a variety of pollinators, including bees and butterflies, which enhances its appeal in any garden setting.
Clematis montana 'Giant Star' thrives in full sun to partial shade, with a preference for cool, shaded roots. It adapts well to various soil types, including chalk, loam, sand, or clay, and is hardy in the UK, tolerating temperatures as low as -20°C. This climber requires minimal pruning, typically only after flowering to manage size or remove dead wood, and can reach heights of up to 1000 cm (394 in) with a spread of 600 cm (236 in), making it an excellent choice for covering pergolas, walls, and fences or for climbing through trees.
Growing Information
Pot up clematis plants and grow them on until large enough to plant in their final positions. When planting clematis, choose a position in sun or semi-shade and plant the climber deeply in moist, fertile, well drained soil. Position the top of the rootball at a depth of 7.5cm (3") below soil level, to encourage new shoots to form from the base of the plant. Clematis dislike soils that are particularly wet or dry. Such soils can be improved by the addition of plenty of well rotted manure or garden compost. When growing clematis in patio containers use a soil based compost such as John Innes No.3. Train clematis plants onto a suitable support such as trellis, wires or a freestanding climbing frame.
