Heliotrope is prized for its deep purple or blue-toned flowers and distinctive vanilla fragrance.

The blooms are small but packed densely into rounded clusters, making them a great choice for containers, raised beds, or spots near walkways where their scent can be appreciated.

Though beautiful, it’s important to note that heliotrope is toxic to pets and children if ingested. It prefers moist, well-drained soil and benefits from regular feeding during the growing season.

For a soft contrast in the garden, pair them with serene white flowers.

8. Catmint (Nepeta faassenii)

• Type: Perennial
• USDA Zones: 3–8
• Light: Full sun to light shade
• Height: 12 to 24 inches
• Bloom Time: Late spring to early fall

• Type: Perennial ground cover
• USDA Zones: 3–9
• Light: Full sun to part shade
• Height: 12 to 18 inches
• Bloom Time: Late spring to early fall

Cranesbill Geraniums are not to be confused with the annual pelargoniums commonly sold in pots.

These true geraniums are hardy perennials that form low, spreading mounds covered in cup-shaped flowers. Purple-flowered varieties bring a soft, natural look to borders and underplantings.

They’re known for their resilience and adaptability, tolerating various soil types and light conditions. Once established, they require little care and often rebloom with a light shearing mid-season.

14. Blazing Star (Liatris spicata)

• Type: Perennial
• USDA Zones: 3–9
• Light: Full sun
• Height: 2 to 4 feet
• Bloom Time: Mid to late summer

Blazing Star stands out with tall, vertical spikes of magenta-purple flowers that bloom from the top down – a rare trait among perennials.

These dramatic, upright blooms add strong vertical lines to mixed borders and are especially effective when planted in groups.

Blazing Star is a magnet for butterflies, particularly monarchs, and also attracts bees. It tolerates poor soil and drought, making it a dependable choice for low-maintenance or pollinator-focused gardens.

15. Dahlia (Dahlia spp.)

• Type: Tender perennial grown from tubers
• USDA Zones: 8–10 (lift and store in colder zones)
• Light: Full sun
• Height: 1 to 5 feet (varies by cultivar)
• Bloom Time: Midsummer to first frost

Dahlias offer some of the most striking purple blooms in the garden, with large, layered flowers that range from deep plum to bluish violet.

Notable purple cultivars include ‘Thomas Edison’, a tall variety with bold, dark purple petals, and ‘Lilac Time’, which has softer, lavender-toned blooms.

While they require more effort in cooler climates – needing to be lifted and stored over winter – their showy presence and variety of forms make them well worth growing.

Design Tips for Creating a Magical Purple Garden

Purple flowers can shape the entire mood of a garden, but the overall effect depends on how you arrange them. Here are some practical design tips to help you make the most of this versatile color:

Use a Range of Purple Shades

Instead of sticking to a single tone, combine light, mid, and deep purples to create depth.

Pale lavenders work well as background or filler plants, while saturated tones like violet or magenta create natural focal points.

Pair Purple with Harmonious or Contrasting Colors

• Harmonious pairings: Combine purple with blue, white, and silver for a soft, calming look – especially effective in evening light.
• Contrasting pairings: Use yellow, orange, or jaw-dropping red flowers next to purple to create bold color tension that draws the eye. This works well for creating garden focal points or energizing a section of the yard.

Balance Height and Structure

• Use tall varieties like Blazing Star, Clematis, or Allium as vertical elements.
• Mound-forming plants such as Catmint and Geranium can soften hard edges.
• Trailing or low-spreading types like Verbena and Petunia help fill in gaps and provide a layered appearance.

Repeat Colors for Cohesion

Repeating similar purple tones throughout different areas of the garden helps tie the whole space together visually.

This is especially helpful in larger gardens where color unity prevents a cluttered look.

Match Planting to Purpose

• Use fragrant varieties like Lavender or Heliotrope near seating areas or paths.
• For borders or walkways, choose compact plants like Aster or Cranesbill Geranium.
• To create visual impact from a distance, plant bold bloomers like Dahlia or Coneflower in clusters.

Tips for Growing and Maintaining Purple Flowers

Choosing the right plants is just the start – maintaining healthy purple blooms requires a bit of planning and care.

These tips will help you keep your garden thriving through the seasons.

Understand Sun and Soil Needs

Most purple flowering plants prefer full sun (at least 6 hours per day), although some, like Cranesbill Geranium and Clematis, can tolerate partial shade.

Well-drained soil is important for nearly all varieties. Avoid planting in areas where water collects or where the soil stays soggy after rain.

Water Consistently – but Don’t Overdo It

Newly planted flowers need consistent moisture until they’re established.

Once mature, many varieties like Lavender, Catmint, and Salvia become drought-tolerant. Always water at the base of the plant to reduce fungal problems and leaf spotting.

Support for Tall or Climbing Varieties

Vining plants like Clematis need something to climb on – a trellis, fence, or arch.

Taller varieties like Dahlia or Blazing Star may need staking, especially in windy areas. Add supports early so the plant can grow into them naturally.

Extend Bloom Time with Deadheading

Remove spent flowers from plants like Petunia, Salvia, and Verbena to encourage continuous blooming.

Some perennials, such as Catmint, will flower again later in the season if lightly sheared after the first flush.

Know What’s Toxic

If you have pets or small children, avoid or carefully place plants like Heliotrope and Dahlia, which can be toxic if ingested.

Check plant safety before placing them in high-traffic or accessible areas.

Overwintering Tender Plants

In zones colder than their range, tender plants like Dahlia and Heliotrope won’t survive winter outdoors.

Dig up dahlia tubers after the first frost, let them dry, and store in a cool, dry place until spring.

FAQs

What purple flowers grow well in shade?

While most purple flowers prefer full sun, some can tolerate partial shade. Cranesbill Geranium, Clematis, and certain varieties of Aster can handle lower light, especially if they receive a few hours of morning sun.

How can I prevent purple flowers from fading in color?

Color fade is usually caused by excessive heat, harsh sunlight, or poor soil conditions.

To reduce fading, make sure the soil stays consistently moist but not soggy, apply mulch to regulate temperature, and avoid planting in spots with harsh afternoon sun.

Can I grow purple flowers in pots year-round?

Yes, but only if the plants are suited for container life and the pots are moved or protected during cold seasons. Lavender, Petunia, and Verbena do well in pots, but perennials may need to be overwintered indoors or replanted each spring in colder zones.

Which purple flowers work best as ground cover?

Cranesbill Geranium and Catmint are excellent choices for ground cover. They spread easily, suppress weeds, and maintain a soft look that works well around borders, pathways, or under taller plants.

What are low-maintenance purple flowers for beginner gardeners?

Lavender, Salvia, Coneflower, and Catmint are great for beginners. They require minimal watering once established, resist common pests, and don’t need constant pruning or feeding to stay healthy.
