Van Noort
‘Bumble Rumble’ is a collarette dahlia with pink and white outer petals, a small cream-coloured inner collar and an open yellow centre. The airy flowers bring movement to garden borders and suit informal cut-flower bouquets from summer until frost. Each pack contains one dormant tuberous root clump for spring planting.
In Canada, plant outdoors once the risk of frost has passed and the soil has warmed. Choose full sun and fertile, well-drained soil. Set the roots about 10 cm deep with the crown and growth buds facing up, leaving 50 cm between plants. Place a stake at planting time to support the stems as they grow without damaging the roots later.
Pair the pink and cream colours with mauve or white flowers for a soft, bright border. Water regularly during active growth and remove faded blooms to encourage new buds. After the first light frosts blacken the foliage, carefully lift the roots before the ground freezes. Let them dry off and store them in a cool, frost-free place for replanting the following spring.
