Winter sunshine in plant form
Acacia dealbata is pure joy in the garden — a cloud of soft silver foliage followed by masses of golden, scented flowers just when you need them most. When everything else is still waking up, mimosa is already celebrating spring, bringing colour, movement and that unmistakable Mediterranean feel.
It’s a brilliant choice for creating a focal point in a sheltered garden, and it also works beautifully trained against a warm wall where it can soak up heat and stay protected from cold winds.
Where it thrives best
Mimosa loves sun and shelter. Give it the warmest spot you have, with free-draining soil (it really dislikes sitting wet in winter). In colder inland gardens, it’s worth choosing a protected microclimate — near a wall, courtyard, or among other evergreen planting — and keeping an eye on frost forecasts while it’s establishing.
Styling ideas
- Perfect for Mediterranean-style planting with olives, lavenders, rosemary and grasses
- Gorgeous as a statement tree in a gravel garden
- Plant near a path or doorway so you can enjoy the fragrance in late winter
Caragh Garden Notebook
- Watering: Water regularly in the first season; once established it’s fairly drought tolerant.
- Feeding: A light spring feed can help, but avoid heavy feeding (too much soft growth can be frost-prone).
- Pruning: Prune after flowering to shape and to keep it compact; remove any dead or frost-damaged growth in spring.
- Top tip: Drainage + shelter = success. If your soil is heavy, plant slightly raised or improve drainage before planting.
