Aster
'Lady in Blue'
Michaelmas daisy
Aster 'Lady in Blue', a delightful Michaelmas daisy, casts a serene spell over UK gardens with its semi-double, daisy-like blooms in soft lavender-blue, each centred with cheerful yellow hearts. The flowers sit atop sturdy, upright stems, creating an airy yet structured display that works beautifully at the back of borders, in mixed perennial beds, or even in pollinator-friendly pockets. Aster 'Lady in Blue' brings a sense of calm sophistication, contrasting elegantly with warmer autumn tones while drawing the eye to its delicate, lilac-hued petals. In UK gardens, this versatile perennial is perfect for creating a long-lasting late-season show, offering colour and charm when many other plants are winding down.
Thriving in full sun to partial shade, Aster novi-belgii 'Lady in Blue' appreciates well-drained soil and will reward gardeners with a generous flowering period throughout late summer and autumn. Its compact yet upright habit ensures that Aster 'Lady in Blue' stays neat without losing its natural grace, making it ideal for borders, cottage-style plantings, or container displays. Whether planted in groups or alongside other autumn bloomers, Aster 'Lady in Blue' guarantees a subtle, enchanting splash of colour. With semi-double blooms that hold up well even in breezy conditions, Aster 'Lady in Blue' (syn. Symphyotrichum novi-belgii 'Lady in Blue') is a dependable, charming addition to UK gardens, bringing elegance, wildlife value, and a touch of lavender-hued magic.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
