Anyone looking for a high-impact shrub for the garden will usually favour plants that unite good looks, toughness and a long flowering season. One of the top choices for many gardeners is Lagerstroemia indica, commonly known in Brazil as resedá or extremosa. Depending on the cultivar and how it is grown, it can reach around 3 metres in height and stay in bloom for roughly 120 days, covering its branches with clustered flowers in shades of pink, white, red, lilac or purple. What is more, it copes well with a range of climates and, once established, needs very little attention.
Why is Lagerstroemia so popular?
The standout feature of Lagerstroemia is its extended flowering period. Throughout summer and into part of autumn, it produces masses of blossoms, making it a focal point in gardens, along pavements and in parks.
Another reason people plant it is the decorative bark. As time passes, the bark naturally peels away, revealing a smooth trunk with varying tones. Even when it is not flowering, the plant continues to add visual interest to the landscape.
How do you grow Lagerstroemia for more flowers?
To flower profusely, extremosa needs plenty of light. Ideally, plant it where it will receive at least six hours of sunlight a day, in soil that is fertile and drains well.
Light pruning during the dormant period also helps encourage fresh growth, and these new shoots will carry the next season’s flowers.
- Full sun for most of the day.
- Fertile, free-draining soil.
- Regular watering while the young plant is establishing.
- Fertiliser rich in organic matter.
- Light pruning at the end of winter.
- Enough room for the canopy to expand.
What are the benefits of growing extremosa?
As well as flowering for a long time, this plant tolerates heat well and can handle short dry spells once mature. It works equally well as a specimen plant, trained into a small ornamental tree, or planted in rows and large beds.
Its flowers also draw bees and other pollinating insects, helping to boost garden biodiversity. In many areas, the leaves turn reddish and orange before dropping, adding an extra decorative effect in autumn.
- Prolonged flowering.
- Can reach around 3 metres tall.
- Attracts pollinators.
- Good heat tolerance.
- Ornamental bark on the trunk.
- Low maintenance after establishment.
Is it worth planting this species?
If you want a garden that stays colourful for several months of the year, extremosa is an excellent option. With plenty of sun, well-prepared soil and occasional pruning, it rewards you with abundant blooms and vigorous growth.
When grown under the right conditions, this ornamental tree can remain one of the garden’s main highlights for many years, requiring only basic routine care.
