4 Stunning Purple Flowers to Add to Your Garden

The colour purple has long been associated with luxury and royalty, making it an ideal choice if you’re looking to elevate the look of your outdoor space. Here are four stunning purple flowers to add a touch of elegance to any garden.

 1. Lavender

Lavender is well known for its soothing fragrance and has a wide range of medicinal uses. It can also be used in cooking and baking, for example in scones, jams or even roast dinners!


With its distinctive long stems and delicate purple spikes, lavender is a must-have purple plant for any garden. This perennial plant not only adds a pop of colour to borders and patios but is also great at attracting pollinators like bees and butterflies.


Lavender thrives in full sun and well-drained soil so choose a sunny spot in your garden and don’t be tempted to over-water. It is relatively drought-tolerant once established and benefits from regular pruning to promote new growth.

 2. Iris

Irises are relatively low maintenance and easy to grow, making them a favourite amongst both beginner and experienced gardeners alike. Known for their exquisite blooms that come in a variety of purple hues from lilac to a deep purpley-blue, the intricate petal structure and rich colour make irises a standout in any garden setting.


Irises can be grown from flower bulbs and are perfect for plant pots on patios or decking or in borders. Like lavender, irises prefer sunny locations with well-drained soil but they require regular watering during the growing season and benefit from dividing every few years to prevent overcrowding.

 3. Allium

Alliums or ornamental onions, produce showy globe-shaped flower heads on tall, slender stems and they are available in a range of shades including beautiful pinks, blues and, of course, purples!


Alliums offer a whimsical touch to gardens and can be planted alongside grass or in borders for a bold, architectural look.


Alliums should be planted in full sun and well-drained soil. They’re excellent at attracting pollinators to your garden and look wonderful in cut-flower displays. Alliums are also drought-tolerant, and if planted in borders won’t require any extra watering, making them incredibly easy to care for.

 4. Clematis

Clematis is one of the most popular garden plants in the UK. Its vines produce an array of large, star-shaped flowers in various shades of purple and it’s fairly easy to grow and care for.


Climbing clematis can be used to cover fences, trellises, or pergolas, while herbaceous types do well in sunny borders. One of the best things about clematis is that with proper care and attention, it’s possible to have beautiful purple flowers all year round.


Clematis climbers need to have cool, moist roots and will grow in full sun or light shade, but bear in mind that shadier spots won’t yield as many flowers. You’ll need to consider how you’ll support the plant’s stems as it grows, and provide a structure for it to twine around, such as a trellis or mesh attached to a fence or wall.
