Astilbe Spotlight

Astilbe ‘Spotlight’ is a brilliant choice for adding colour and texture to shadier borders. It produces elegant, feathery flower plumes in soft pink tones above fresh, fern-like foliage, creating a light, airy look that lifts planting schemes beautifully. It’s ideal for woodland-style gardens, mixed borders, and anywhere the soil stays reliably moist—especially near ponds and streams. Astilbes also make lovely cut stems, and even when not in flower the foliage gives a lush, leafy feel through summer.

If you’ve got a slightly shaded spot that needs a little “wow” without being high maintenance, ‘Spotlight’ is a great pick.

Planting Instructions

When to Plant:

Plant in spring or autumn, while the soil is moist and workable. Container-grown plants can be planted at most times of year, avoiding frozen or waterlogged conditions.

Where to Plant:
Choose a position in partial shade (or light sun if the soil stays reliably moist) with moist, fertile, well-drained soil. Astilbe is ideal for shady borders, woodland planting, along streams or ponds, and moist mixed borders. Avoid hot, baking sun and very dry soil.

How to Plant:

• Depth: Plant at the same depth as in the pot, with the crown level with the soil surface.
• Spacing: Space 35–45 cm (14–18 inches) apart to allow clumps to fill out.
• Soil Prep: Mix in plenty of well-rotted compost to retain moisture and improve fertility.

Watering:
Water well after planting and keep the soil consistently moist, especially in the first season and during dry spells. Astilbes do not like drying out.

Aftercare Tips:

• Mulch in spring to help conserve moisture.
• Deadhead spent flower plumes if you prefer a tidy look, or leave them for gentle autumn structure.
• Cut back old stems and foliage in late winter or early spring.
• Divide clumps every 3–4 years in spring or autumn to maintain vigour.

Top Tip:
Astilbes love moisture. If you keep the soil evenly moist, ‘Spotlight’ will reward you with stronger growth and more flower plumes. Pair it with Hostas and Ferns for a classic woodland look.
