Our "Bloom or Bust" Promise

A garden chameleon! In cool weather, the lilac tones pop; in summer heat, warm peaches take over—it’s like having two plants in one.

Dahlia ‘Rainbow Silence’ is a delightful decorative variety that features a harmonious blend of soft peach, lilac, and yellow tones. The petals transition gently between these warm, sunset hues, creating a multifaceted bloom that looks different from every angle.

This variety forms a bushy, medium-height plant with strong stems that display the flowers well above the foliage. The blooms are fully double and rounded, offering a classic dahlia shape with a modern, pastel colour twist.

Plant in a sunny, sheltered position in moist, fertile soil. The complex colouring of the petals is best appreciated in a spot where the flowers can be viewed up close, such as near a path or patio.

Water regularly during the growing season and apply a balanced liquid feed every couple of weeks once the buds appear. Remove spent flowers to channel energy into new growth and lift the tubers for winter storage in colder regions.

A brilliant choice for pastel-themed gardens, ‘Rainbow Silence’ provides a soft, glowing presence in the border and makes a wonderful cut flower that bridges the gap between pink and yellow arrangements.

Where to Plant:

Thrives in a sunny border where the pastel colours can be appreciated. Requires moist, fertile soil. Avoid planting in deep shade as this will reduce flowering.

How to Plant:

Plant tubers 10–15cm deep after the last frost. Space plants 60cm apart to allow for airflow. Insert a bamboo cane for support at the time of planting to avoid piercing the tubers later.

Aftercare:

Water regularly, especially during dry spells in spring. Pinch out the growing tips to create a bushier habit. Remove dead flowers regularly to extend the season, and lift tubers for winter storage in colder areas.
