Description
If you’ve ever wanted a plant that makes late summer feel like a second spring, Lagerstroemia indica is it.
Crape myrtle is loved for its ruffled, crepe-paper flowers that arrive when so many shrubs are winding down. In the right spot, it flowers generously through late summer, then follows with glowing autumn colour — and, as it matures, develops that beautiful, smooth, peeling bark that looks quietly sculptural in winter.
It’s a plant with real “holiday garden” energy — but it’s also surprisingly elegant, and a brilliant choice for a sunny courtyard or a warm, sheltered border.

Where to plant it (warmth matters)
In Ireland and the UK, crape myrtle needs the best microclimate you can give it:
In Ireland and the UK, crape myrtle needs the best microclimate you can give it:
- Full sun
- Shelter from cold winds
- Ideally near a south- or west-facing wall or in a courtyard that holds heat
The warmer the spot, the better the flowering.
Soil & drainage
It likes soil that’s fertile and holds some moisture, but it must drain freely. Add compost at planting time, and avoid cold, waterlogged ground.

Watering
- Water regularly while establishing, especially in its first summer.
- Once settled, it’s fairly resilient, but flowering is best when it doesn’t dry out completely in prolonged warm spells.
Feeding
A spring feed and a mulch of compost will support strong growth and better flowering. Avoid high-nitrogen feeds (too much leafy growth, fewer flowers).

Pruning

Pruning depends on how you want it to grow (shrub vs small tree), but in general:
- Prune in late winter/early spring to shape and encourage strong new flowering growth.
- Remove any weak, crossing, or congested stems to keep the centre open.
Winter care
Young plants appreciate shelter while they establish. A mulch around the base helps protect roots, and a warm position reduces the risk of dieback in harsh winters.

Design notes
- Beautiful with lavender, rosemary, salvias, grasses, and Mediterranean planting
- Stunning as a feature in a gravel garden with stone and terracotta
- A perfect “late-season hero” near seating areas where you’ll actually notice it
