Astilbe Hot Pearls

Astilbe ‘Hot Pearls’ is a fabulous perennial for bringing bright, fluffy plumes of colour to shadier parts of the garden. It produces eye-catching flower spikes in vivid pink tones (with that classic “feathery” Astilbe look) held above attractive, fern-like foliage. It’s perfect for lifting mixed borders, brightening woodland-style planting, and adding a soft, romantic feel around ponds or in consistently moist areas. Astilbes also make lovely cut stems, and the foliage stays neat and textural long after flowering.

If your garden has a spot that gets a bit less sun but holds moisture well, ‘Hot Pearls’ is an absolute winner.

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 very dry soil and hot, baking sun.

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 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:
The secret to happy Astilbes is moisture. If you’re planting in a sunnier spot, make sure the soil never dries out—a thick mulch and regular watering will keep ‘Hot Pearls’ looking its best.
