The flowers of Ageratum are very soft and fluffy with interesting shades of blue that can instantly enliven a garden. Ageratum is frequently used as a ground cover or border plant and has a fuzzy appearance with small blooms that thrive in borders, containers, window boxes or mixed flower gardens. This is an ideal plant for gardeners seeking low growing with long flowering time for continuous seasonal color.
What is Ageratum's flower?
Ageratum is a flowering plant of the Asteraceae family. The most commonly cultivated species is Ageratum houstonianum, which is also known as floss flower. It features rounded flower clusters that are typically blue, lavender, pink or white, and are usually blue in color.
Ageratum may have a more compact habit of growth or become a more full plant depending on the variety and growing conditions. The small flowers form a dense spikelet, giving this plant a soft, cushion shape, particularly when grown in groups.
Selecting the right location
Ageratum grows best in a location that receives plenty of sunlight. Plenty of sun (about 6 hours per day) can promote good foliage and prolific bloom. If the climate is very hot, some protection from hot afternoon sun by providing shade may be helpful.
The soil should be fertile, loose and well drained. Good drainage is especially important for container gardening as Ageratum will not grow well if it is always damp.
How to Grow Ageratum
Ageratum can be grown from seeds or young plants. Seed propagation: Sown in light to the surface of wet soil, as the seeds tend to require light in order to germinate. Maintain a moist growing medium but not soggy.
After established water when the top layer soil dries. Ensure good growth by providing some watering, but not too much, particularly during warm weather. Organic material or compost can be added to the soil to provide nutrition and enhance soil structure.
To promote a bushier habit of growth, pinching out the growing tips when the plant is young. Deadheading can help maintain the plant's neatness and can promote more flowers during the blooming season.
Ageratum in Containers and Garden Designs
One of the best features of ageratum is its versatility. Compact varieties make great potted plants, hanging plants, planters for a balcony and small gardens. Ageratum can be used as a pathway plant or a colorful edging plant in larger landscapes.
It has blue colored flowers which complement other white, yellow, pink or purple flowering plants. Ageratum can be used with other flowers that contrast in color to provide an interesting and colorful garden scene.
Common Problems to Watch For
Very tolerant of most conditions but will have difficulties if the drainage is poor, if it is over-watered or if there is not enough air circulation. Sometimes the plant is damaged by aphids, spider mites and other small garden pests. Properly dry leaves, space and proper growing conditions can help keep plants healthier.
Bring Soft Color to Your Garden
Ageratum is a great plant for traditional gardens or small containers because of its fluffy blooms, small size, and versatility. Ageratum can offer a nice light color infusion for its flowering period, either in classic blue or for the adventurous, try pink, lavender and white. These delightful blooms can be a lovely addition to a flourishing landscape with a bit of care, some watering, drainage, and sunlight.
