One of the most popular of clematis, boasting a long flowering period and sumptuous colour, Clematis ‘Niobe’ has been recognised with an RHS Award of Garden Merit. From late spring to early autumn, the single flowers open into blooms around 15cm across, with velvety, crimson petals that deepen in colour as they age and are set off by contrasting greenish-yellow stamens. This small to medium climber is ideal for a large container, climbing over a low wall or scrambling up an obelisk in the border. Pruning group 2. Height: 300cm (118). Spread 90cm (35).
