  • The fast-track to a hassle-free garden - just plant, water and enjoy!
  • Quality plants delivered to your door, hardened off and ready to plant out
  • Fully-grown, super-robust, healthy plants
Our garden ready plants are selected for garden performance, straight from the nursery. We send them to you 'green' ahead of flowering (but please note some varieties may show a few blooms), which means plants will establish quickly and all their energy goes into producing better roots, so they produce more flowers throughout the season.

A large-flowered, vigorous variety of annual ageratum with powder-puff flower heads of soft, lavender blue. The fluffy, weather resistant blooms are particularly attractive to butterflies. With a dense, compact habit, Ageratum houstonianum 'Blue Danube' is perfect for adding texture and colour to bedding, borders and containers. Height: 20cm (8"). Spread: 25cm (10").

Pot up floss flower plug plants into 9cm pots and grow them on in frost free conditions until large enough to plant outdoors. When agaratum plants are well grown, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in a sheltered position in full sun on moist, fertile, well drained soil.
Water regularly until ageratum plants are fully established. Deadhead faded flowers throughout the summer to encourage more blooms to be produced.
