Description

Lagerstroemia indica 'Bianco Grassi' is a white crape myrtle that covers its branches in large heads of pure white, double, crinkled flowers from July to September. Leaves turn yellow-orange in autumn, and the smooth grey bark flakes with age.

It is rated RHS H3, hardy to about -5°C, so it needs a warm, sheltered spot, and young plants and plants in pots need protection below -5°C. It flowers well only after a warm summer, so give it the hottest position you have, ideally against a south- or west-facing wall.

An upright, vigorous Italian selection reaching about 4m, it makes a small flowering tree for exotic borders or a statement shrub in a large pot on a sunny patio.

What you receive: a young plant in a 23cm (5 litre) pot.

What to Expect

Seasonal by nature: what to expect

  • Grown outdoors, the way nature intended. Weather-tested and hardened in real UK conditions, so they thrive in your garden. A few marks on the older leaves are normal, the sign of a tough, real plant rather than a flaw.
  • It follows the seasons. Depending on when you order, your plant may arrive cut back, dormant or leafless. That's healthy: dormancy is the ideal time to plant.
  • Posted, not posed. Big leafy plants like bananas and gingers may be trimmed or gently folded to travel safely. It does the plant no harm, and it powers away again in spring.

Not sure what to expect from yours? Dormant, cut-back or weather-marked plants are all perfectly healthy and normal. Read what to expect through the seasons

Frequently Asked Questions

Is Lagerstroemia hardy in the UK?

Partly. 'Bianco Grassi' is rated RHS H3, hardy to about -5°C, so it suits milder and sheltered gardens, and young plants or plants in pots need protection below -5°C. The bigger limit in the UK is summer heat: it flowers well only after a warm summer.

Where is the best place to plant Lagerstroemia indica?

In full sun in the warmest, most sheltered spot you have, ideally against a south- or west-facing wall, in well-drained soil. It also suits a large container, one of our plants for pots, which can be moved under cover in a cold spell.

Is Lagerstroemia indica fast growing?

'Bianco Grassi' is an upright, vigorous selection that reaches about 4m as a small tree or large shrub.

Can I keep crape myrtle small?

Yes, with pruning. It flowers on the current year's growth, so cut back in late winter or early spring: take off spent flower tips and weak shoots, and cut back harder to encourage flowering. Avoid lopping the main stems to stumps.

How do I get crape myrtle to flower?

Give it heat. In the UK it flowers well only after a warm summer in a hot, sunny spot, and the flowers come late, from July to September. Pruning in late winter helps too, since flowers form on the current year's growth. A sunny bed of exotic border plants or a south-facing wall gives it the best chance.

Is it 'Bianco Grassi' or 'Bianca Grassi'?

'Bianco Grassi' is the recorded spelling, used by the RHS and by Italian and UK specialists; 'Bianca Grassi' is a common variant on Italian retail sites. The RHS adds (d) to the name to mark the double flowers. The species is the crape myrtle, also spelt crepe myrtle.

Does my plant come with a pot?
Your plant will arrive in its nursery grow pot — the plastic pot it's been growing in. We don't include a decorative pot as standard, and there's a good reason for that: it means you get to choose one that fits your space and style, rather than being stuck with something that doesn't suit your home.

It also means you're not paying extra for a pot you might not want. The nursery pot is perfectly fine to keep your plant in for a while, just pop it inside a decorative cover pot or cache pot and you're good to go. When you're ready to repot (usually after a growing season or when roots start poking out the bottom), you can move it into something more permanent with fresh soil.

If you're not sure what size cover pot to go for, check the pot selector tool listed above, you'll want a decorative pot that's a centimetre or two wider than that to give it a comfortable fit.
How big will my plant be when it arrives?
Every plant on our site includes the pot size (e.g. 12cm) and, where possible, an approximate height. That's the most reliable way to set your expectations, photos can sometimes make a plant look larger or smaller than it really is.

If you're thinking "that sounds quite small for the price," here's something worth knowing: younger, smaller plants almost always adapt better to your home than larger ones. They adjust faster to your light and humidity, put out new growth more quickly, and tend to establish stronger root systems long-term. A plant that grows into your space will usually outperform one that was already big when it arrived.

That said, every plant is an individual. The one you receive may vary slightly in height, shape, or fullness compared to the photo, that's the nature of living things, not a quality issue. We select healthy, well-established specimens, and if you ever feel your plant doesn't match what you were expecting, just get in touch and we'll take a look.
What makes your plants different from the supermarket or garden centre?
There's a big difference between a plant that's been sitting under on a retail shelf and one that's been looked after and cared for by people who specialise in exactly this.

Our plants are grown in house or sourced from specialist nurseries, many of them varieties you simply won't find at your local garden centre or supermarket. Before anything leaves us, it's checked over by our horticultural team to make sure it's healthy, well-rooted, and ready to thrive in your home. We're not shifting volume off a pallet, we're choosing plants we'd want to keep ourselves.

When you buy from a supermarket, you get a plant and a generic care label. When you buy from us, you get the knowledge that comes with it, detailed care guidance, a team you can actually contact if something isn't going right, and the confidence that what's arriving has been looked after properly from the moment it was grown to the moment it reaches your door.

We're a specialist nursery first, not a retailer that happens to sell plants. That's the difference, and you'll see it the moment you open the box.
What should I do when my plant arrives?
First things first, unbox it as soon as you can. Plants don't love being in dark boxes any more than you would, and the sooner yours is out and breathing, the better.

Remove all the packaging carefully, give the soil a check with your finger, and water lightly if it feels dry. Then find it a spot with appropriate light, but avoid putting it straight into harsh direct sun or next to a radiator. Think of it like arriving somewhere new after a long journey: it needs a moment to adjust.

It's completely normal for your plant to look a little tired or droopy after transit. This is called transit stress, and most plants bounce back within a week or two. You might see a yellow leaf or some drooping, don't panic, and resist the urge to overwater or start repotting straight away.

Our advice for the first couple of weeks: leave it in its nursery pot, water it only when the top layer of soil feels dry, and let it acclimatise to your home's light, temperature, and humidity. Once it's settled in and showing signs of new growth, you can think about repotting or moving it to its permanent spot.

Every plant we sell comes with a care guide on the product page so you'll know exactly what it needs going forward. And if anything doesn't look right, get in touch with our team, we're always happy to help.
Will my plant survive being shipped?
Yes! and we go to serious lengths to make sure of it. Every plant is hand-packed by our team with protective wrapping and secure, custom-designed boxes to keep it stable and safe in transit. We've shipped hundreds of thousands of plants across the UK and our packaging methods have been refined over years to handle the bumps and jolts of delivery.

During colder months, we monitor weather forecasts and offer heat packs where needed to protect against frost. In extreme conditions, we may hold your order for a day or two rather than risk sending it out, we'd rather you wait an extra day than receive a stressed plant.

That said, plants are living things, and the occasional transit wobble can happen. If your plant arrives damaged or isn't in the condition you'd expect, just get in touch within 7 days with a photo, and we'll make it right, whether that's a replacement or a full refund. No fuss.

The short version: we treat every box like it's going to someone who really cares about what's inside, because it is.
