Ageratum Blue Danube F1

Ageratum 'Blue Danube' F1 is a vigorous annual hybrid variety that displays large, soft, fluffy clusters of lavender blue flowers all summer long. This RHS AGM winner is particularly weather resistant and coveted by butterflies. It forms small dense clumps that are perfect at the front of beds, in borders and pots. Easy to grow in a sunny location, in cool soil.

Ageratum 'Blue Danube' F1 is bred from Ageratum houstonianum, a perennial often grown as an annual that belongs to the Asteraceae family and is native to Central America and the West Indies. It forms bushy, rounded cushions that measure 25 cm high and 20 cm wide. The abundant, well-branched, pubescent stems stand upright and spread out gracefully. The dark bluish-green leaves, which are also pubescent, are ovate to triangular with serrated margins. From April until early autumn, this variety will bloom continuously providing it is regularly deadheaded. The foliage is smothered in soft lavender-blue flowerheads, grouped in pompom-like clusters.

Mexican Ageratums are pollinator-friendly plants that are popular in urban landscaping and gardens. Their generous blooms and bright colours combine well with many other low-growing bedding plants such as marigolds, calendulas and red sage. Create magnificent pastel-coloured carpets at the forefront of beds by matching them with pink begonias, busy Lizzies or fragrant alyssums. Ageratums are also very pretty grown alongside fuchsias in pots indoors, on the patio or balcony.
