Classic bedding annual

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").

Garden Ready 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.

Plant Size Height Up to 20cm (8in)
Spread Up to 30cm (12in)

Pot up floss flower plug plants into 9cm pots and grow them on in frost free conditions until large enough to plant outdoors. When ageratum 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.

Van Meuwen strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.
