Description
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.
Asters are called Michaelmas daisies because they bloom around Michaelmas in late September, bringing fresh colour just as summer fades.

Useful information
-
Soak your Aster 'Lady in Blue' roots in water for 3-6 hours prior to planting.
Plant your "Michaelmas daisy" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
