Aster dumosus 'Lady in Blue' | Michaelmas daisy

Aster dumosus 'Lady in Blue', commonly known as the Michaelmas daisy, is a charming perennial that graces gardens with its delightful blue and purple blossoms. Flowering late in the season, from August to October, this cultivar extends the color in your garden right into the fall, providing a splash of color when many other plants have ceased to bloom.

Key Features

The Aster is an excellent choice for gardeners seeking to add a touch of blue to their borders, group plantings, or edges.
'Lady in Blue' features a bushy, spreading growth habit that reaches a modest height of 40 cm, allowing it to blend seamlessly among other plants without overshadowing them.
Its deciduous foliage remains a lush green from spring through autumn, providing a verdant backdrop for its vibrant purple flowers that emerge during the summer and autumn months.
This Aster variety is well-suited for growth in a variety of well-drained soil types and thrives in both sun and partial shade.

Tips

For best results, place 'Lady in Blue' in a sunny location to encourage optimal flowering, though it will also tolerate partial shade.
Regular watering will keep the plant healthy, particularly during dry spells, as it is not drought resistant.
To maintain vigor and promote more abundant blooms, divide the plant every few years in the spring or autumn. This simple propagation method not only rejuvenates the plant but also allows you to increase your collection or share with fellow gardeners.

Ideal placement of a Aster dumosus 'Lady in Blue'

For optimal growth and flowering, Aster dumosus 'Lady in Blue' thrives best when situated in a location with full sun to partial shade. Ensuring a well-drained soil is essential for the health of the plant, as it can adapt to a range of soil types. This species flourishes in areas where it can receive plenty of light, which encourages its vibrant purple blooms to emerge from late summer through autumn. Although the plant has a bushy spreading growth habit, it remains compact, reaching up to 40 cm in height, making it an ideal choice for borders and edge plantings.

How do I plant a Aster dumosus 'Lady in Blue'?

For optimal establishment, Aster dumosus 'Lady in Blue' should be planted in a location that receives full sun to partial shade. This variety thrives in all soil types, provided they are well-drained. When placing each plant, ensure adequate spacing to accommodate their bushy, spreading growth habit, which reaches a height of approximately 40 cm.

Planting can be performed effectively in the pot-grown condition, allowing for flexibility in timing. The soil should be prepared to promote good root development. After planting, maintain an average watering schedule to support the plant's needs, especially during the active growth period leading up to its vibrant flowering months from late summer into autumn.

Pruning a Aster dumosus 'Lady in Blue'

To ensure the robust vitality of Aster dumosus 'Lady in Blue', a judicious approach to pruning is advised. In late autumn or early spring, cut back the stems to just above ground level, allowing for a flush of new growth in the coming season. This will encourage a more dense, bushy form and enhance the potential for abundant flowering. Proper pruning also prevents the center of the plant from becoming too woody, which can impede the species' characteristic sprawling habit.

Watering a Aster dumosus 'Lady in Blue'

Aster dumosus 'Lady in Blue' thrives with consistent moisture, particularly during its blooming period from late summer to autumn. Although it has an average water need, periods of drought can impact its lush foliage and vibrant blooms. To maintain its vitality, it is recommended to establish a regular watering schedule, ensuring the soil remains well-drained but not waterlogged. During prolonged dry spells, additional watering may be necessary to sustain the plant's health and flowering capacity. Balancing moisture levels is key to supporting this species' bushy spreading growth habit and maximizing its ornamental appeal.

Fertilising a Aster dumosus 'Lady in Blue'

For the Aster dumosus 'Lady in Blue', a balanced approach to fertilization is beneficial in supporting its lush foliage and vibrant late-season blooms. Applying a general-purpose fertilizer in the early spring can help kickstart its growth. As this species thrives in well-drained soil, the nutrients will assist in establishing strong roots and robust stems. A second application of fertilizer may be advantageous as the plant enters its peak blooming period in late summer, providing an extra boost to sustain its flowering through to October. It is essential to ensure that the fertilizer is distributed evenly around the base of the plant, avoiding direct contact with the leaves and stems to prevent burn. Consistent watering after fertilization will help to dissolve nutrients into the soil, making them readily available for uptake by the plant.
