Clematis 'Happy Birthday'
- If you were to give us this plant as a birthday present, we'd be bloomin' chuffed! With its showy, purple sepal/white anther combination, this clematis is guaranteed to turn heads wherever it's found
- The six-sepal flowers emerge an intense purple before fading to more of a slate-like, blueish hue with age, offering a brilliant contrast to the plant's lush green foliage
- Growing to just a few metres tall, this variety is perfect for twining over a pergola, or growing up an obelisk placed at the heart of a flower bed
- This variety is a recipient of the Royal Horticultural Society's Award of Garden Merit, which is conferred upon plants that have been proven to perform particularly well in British gardens
- Please Note: Our climbers are pruned back each winter, and some during the summer, so you may find at certain times of year they do not cover the whole 90cm cane. This is intentional to ensure the best growth when you plant out
