Description
Lagerstroemia indica 'Dynamite', has flowers of a vibrant colour. This lovely deciduous and hardy bush is charming with its spreading and rounded habit, its dark foliage, red young shoots, decorative bark, and stunning cherry red summer flowers. Loving sun and heat, it is undoubtedly one of the most beautiful summer-flowering bushes. It deserves a special place in the garden. Planted in a large pot on the terrace, it will earn you compliments from everyone.
Lagerstroemia indica 'Dynamite' belongs to the Lythraceae family. Lagerstroemia indica, from which it originates, is native to China. This shrub has a bushy and branched habit, with a spreading and rounded crown. It reaches a height of 4m (13ft) and a diameter of 3m (10ft) at maturity. Its growth is quite fast. It starts flowering in July and continues until October. The flowers are characterized by fine pedicels each carrying five undulated-edged petals. The flowers, with a texture reminiscent of crepe, are gathered in large dense panicles at the end of the current year's branches. In 'Dynamite', the buds are crimson, then blooming into intense cherry red. The tough and deciduous, small ovate leaves start red, then turn dark green and shiny, sometimes taking on pretty yellow or red hues in autumn depending on the climate. Finally its bark is beautiful, smooth, beige striated with brown-red. and peels off in colourful patches (cinnamon, muted red, old rose, cream).
Dynamite will look good in a shrub bed or flowering hedge, or emerging from a mound of perennials. Create a bed like a bouquet, with Campanula pyramidalis, Salvia sclarea, Aster laevis. In autumn its colour accompanies the asters. In a large pot on the terrace, it puts on a show while the summer blooms slow down. Imagine a tricolor plant tapestry as a ground cover to highlight the Dynamite Summer Lilac. A weave of thyme, oregano, and silver baskets will dress the base of its trunk, accentuate its bark, and reflect its flowering.
NB: Karl Von Linné named this tree to pay tribute to his friend Magnus Von Lagestroem (1696 - 1759), who had sent it to him from India for identification. Originally, this tree was used to decorate Chinese temples. We would like to point out that this tree produces fruits with a narcotic effect if ingested.

Planting and care
We advise you to plant Lagestroemia indica 'Dynamite' in spring, after the last frost, in a very sunny and sheltered location, in rich, moist, well-drained and preferably non-chalky soil. It will appreciate the addition of compost and a thick mulch of dead leaves, especially during the first two winters in cold regions. It is necessary to prune the floriferous branches very short in February-March, leaving only 4 to 6 buds to balance its habit and stimulate the growth of future flower-bearing branches. If necessary, remove weak twigs and poorly positioned branches.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
