Why Choose Bluish Purple Flowers? The Unspoken Benefits
Beyond their sheer beauty, there are so many wonderful reasons to plant these cool-toned wonders. This isn’t just about adding color; it’s about transforming the entire feel and function of your garden. Understanding the benefits of bluish purple flower varieties can help you design a more intentional and rewarding space.

Our Top 12 Bluish Purple Flower Varieties for Every Garden
Ready to find your perfect match? Here is a curated list of my absolute favorite, reliable, and stunning bluish purple flowers. I’ve grown every one of these in my own garden and can vouch for their beauty and performance. This is the ultimate starting point for your how to bluish purple flower journey.
1. Salvia ‘May Night’ (Salvia nemorosa)
If I could only recommend one, this would be it. ‘May Night’ Salvia produces dense spikes of intense, deep indigo flowers. It’s tough, drought-tolerant once established, and a true workhorse. Don’t worry—these flowers are perfect for beginners!
Pro Tip: After the first major flush of blooms fades, cut the entire plant back by about half. You’ll be rewarded with a second, smaller wave of flowers in late summer.
2. Catmint (Nepeta faassenii)
Catmint is the definition of easy-care elegance. Its sprays of hazy, lavender-blue flowers bloom for months on end over soft, gray-green foliage. It’s wonderfully fragrant and incredibly resistant to deer and pests.
Pro Tip: Plant Catmint along a walkway or patio edge where you can brush against the leaves and release their lovely scent.
3. Perennial Geranium ‘Rozanne’ (Geranium ‘Rozanne’)
This isn’t your grandmother’s window box geranium! ‘Rozanne’ is a sprawling perennial that produces an astonishing number of violet-blue flowers with white centers from late spring until the first frost. It’s perfect for weaving through other plants or spilling over a container edge.
Pro Tip: If the plant starts to look tired mid-summer, give it a light shearing to encourage fresh growth and even more blooms.
4. Lavender ‘Hidcote’ (Lavandula angustifolia)
No garden is complete without the classic scent and beauty of Lavender. ‘Hidcote’ is a fantastic variety known for its deep purple-blue flower spikes and compact, silvery foliage. It needs full sun and excellent drainage to thrive.
Pro Tip: Harvest the flower wands just as the buds begin to open for the most intense fragrance and color for drying.
5. Spike Speedwell (Veronica ‘Royal Candles’)
For a tidy, upright splash of color, look no further than Veronica. ‘Royal Candles’ features vibrant, bluish purple flower spikes that stand at attention in the garden. It’s a long-blooming perennial that attracts butterflies in droves.
Pro Tip: Deadheading the spent flower spikes is key to encouraging continuous blooming throughout the summer.
6. Siberian Iris (Iris sibirica)
Siberian Irises are more delicate and graceful than their bearded cousins. They produce intricate, velvety flowers in stunning shades of blue, violet, and purple atop grass-like foliage. They are remarkably low-maintenance and disease-resistant.
Pro Tip: Unlike Bearded Iris, Siberian Iris loves moist soil and won’t tolerate drying out completely. They are a great choice for areas with heavier soil.
7. Bellflower (Campanula)
From the charming, low-growing ‘Blue Clips’ to the stately ‘Sarastro’, there’s a Campanula for every garden. These plants produce beautiful, bell-shaped flowers in lovely shades of periwinkle and violet-blue.
Pro Tip: Many Campanula varieties spread by runners to form a lovely groundcover. Be sure to give them space to roam or choose a clumping variety if you prefer a neater habit.
8. Delphinium
For pure, jaw-dropping drama, nothing beats Delphinium. Their towering spires of intensely colored flowers are the stars of the early summer garden. They come in some of the truest blues and purples you can find.
Pro Tip: Delphiniums are heavy feeders and require staking in all but the most sheltered locations to prevent their hollow stems from snapping.
9. Clematis ‘The President’
Let’s not forget the climbers! ‘The President’ is a classic, reliable Clematis variety that produces huge, star-shaped flowers in a rich, velvety violet-blue. It blooms in late spring and again in late summer.
Pro Tip: Remember the Clematis motto: “feet in the shade, head in the sun.” Mulch the base of the plant or plant a shallow-rooted perennial in front of it to keep the roots cool.
10. Morning Glory ‘Heavenly Blue’ (Ipomoea tricolor)
For a quick-growing annual vine, ‘Heavenly Blue’ is iconic. While technically more sky-blue, the flowers have a lovely purplish throat and the overall effect fits perfectly in a cool-toned garden. Each flower lasts only a day, but the vine produces them in abundance.
Pro Tip: Soak the seeds overnight before planting to speed up germination. Be aware they can self-seed readily in warmer climates.
11. Monkshood (Aconitum)
Monkshood offers stunning, hooded spires of deep bluish purple flowers in late summer and fall, a time when many other perennials are fading. It’s a fantastic choice for partial shade.
Pro Tip and Important Warning: All parts of the Monkshood plant are highly toxic if ingested. Always wear gloves when handling it and do not plant it where children or pets play.
12. Lily of the Nile (Agapanthus)
For a touch of the exotic, Agapanthus sends up tall, sturdy stems topped with large, spherical clusters of trumpet-shaped flowers. They are spectacular in containers and thrive in full sun.
Pro Tip: Agapanthus blooms best when its roots are slightly crowded, so don’t be too quick to repot it into a larger container.
The Ultimate Bluish Purple Flower Care Guide
Now that you have some beautiful plants in mind, let’s cover the essentials. Following these bluish purple flower best practices will ensure your garden is healthy, vibrant, and full of blooms.
Getting the Soil Just Right
Most of the flowers on our list prefer well-draining soil. If you have heavy clay, amend it with compost or other organic matter to improve its structure. This is the single most important step for success! A soil rich in organic matter provides nutrients and helps retain the right amount of moisture.
Sun and Water Wisdom
Pay close attention to the sun requirements for each plant. Most bluish purple perennials, like Salvia and Lavender, need at least 6 hours of direct sun to produce the most flowers. For watering, the general rule is to water deeply and infrequently. This encourages roots to grow deeper, making plants more resilient to drought.
Feeding for Fabulous Blooms
Go easy on the nitrogen! A fertilizer that is high in nitrogen will give you lots of lush green leaves but very few flowers. Instead, use a balanced, all-purpose flower fertilizer or one that is slightly higher in phosphorus (the middle number on the bag) to encourage robust blooming.
Sustainable and Eco-Friendly Bluish Purple Flower Gardening
Creating a beautiful garden can and should go hand-in-hand with caring for our planet. Embracing a sustainable bluish purple flower approach is not only better for the environment but also creates a more resilient and lower-maintenance garden.
Water-Wise Techniques
Group plants with similar water needs together. Apply a 2-3 inch layer of organic mulch (like shredded bark or compost) around your plants. Mulch is a gardener’s best friend—it conserves soil moisture, suppresses weeds, and enriches the soil as it breaks down.
Attracting Pollinators Naturally
Many of the best bluish purple flowers are pollinator powerhouses. To create an eco-friendly bluish purple flower haven, plant in drifts or groups of 3-5 of the same plant. This creates a larger target for bees and butterflies. Most importantly, avoid using chemical pesticides, which can harm these beneficial insects.
Solving Common Problems with Bluish Purple Flowers
Even the most experienced gardeners run into issues. Don’t be discouraged! Here are solutions to some common problems with bluish purple flower varieties that you might encounter.
Why Aren’t My Flowers Blooming?
This is the most common question I get! The culprit is usually one of three things:
- Not Enough Sun: Most flowering perennials need at least 6 hours of direct sun. If they are in too much shade, they will prioritize leaf growth over flowers.
- Too Much Nitrogen: As mentioned above, excess nitrogen fertilizer leads to leafy growth at the expense of blooms.
- Improper Pruning: Some plants bloom on new wood, others on old. Forgetting to deadhead can also signal to the plant that its job is done for the season.
Dealing with Pests and Diseases
The best defense is a good offense. Healthy plants are less susceptible to problems. Ensure good air circulation by giving plants enough space. If you spot issues like powdery mildew (a white, dusty coating on leaves), you can often treat it with an organic fungicide or even a simple spray of one part milk to nine parts water.
Leggy Stems and Flopping
For mounding perennials like Catmint and Salvia that can get a bit floppy, there’s a fantastic technique called the “Chelsea Chop.” Around late spring (late May in the UK, hence the name), cut the entire plant back by about one-third. This delays flowering slightly but results in a much sturdier, more compact plant that won’t flop over later in the season.
Frequently Asked Questions About Bluish Purple Flowers
Which bluish purple flower is easiest for beginners?
Hands down, I would recommend either Catmint (Nepeta) or Salvia ‘May Night’. Both are incredibly forgiving, drought-tolerant once established, and bloom for a very long time with minimal fuss. They are a fantastic way to build your gardening confidence.
Can I grow these flowers in containers?
Absolutely! Many of the plants on our list do wonderfully in pots. Perennial Geranium ‘Rozanne’, Spike Speedwell, and Agapanthus are all excellent choices. Just be sure to use a quality potting mix and a container with good drainage holes.
How can I make my blue and purple flowers look more vibrant?
Healthy plants produce the best color. Ensure they get the right amount of sun and are planted in rich, well-draining soil. A dose of phosphorus-rich fertilizer (like a bloom booster) in the spring can also help enhance flower color and production.
What flowers pair well with bluish purple tones?
For a high-contrast, energetic look, pair them with yellows (like Coreopsis or Black-Eyed Susans) and oranges (like Coneflowers). For a soft, harmonious feel, plant them alongside pinks (like Phlox), whites (like Shasta Daisies), and plants with silvery foliage (like Lamb’s Ear).
