7 Plants with Small Purple Flowers to Consider Growing

Plants with small purple flowers can be so elegant and delicate-looking. Which ones should you consider growing?

You may be surprised to learn that purple is one of the most popular colors for flowers. We’re spotlighting flowers in this article that have purple hues that are certain to add elegance to your landscape. 

1. Verbena 

The verbena plant is recognizable by its clusters of purple flowers. Its blooms attract butterflies and bees from early summer until the first freeze and can be found growing naturally in meadows and along slopes and riverbanks. 

Aside from its aesthetic value, verbena has medicinal benefits. It’s often used as an herbal tea and can help promote milk production in nursing women. Verbena is also sometimes used as a libido booster. 

This purple flowering plant is popular in cottage gardens, mass plantings, along landscape borders, and in rock gardens.

Plant verbena in full sun and well-drained soil. Also, regularly trim back withered or dead blossoms to promote fresh flower growth while maintaining plant spread.

2. Catmint 

Catmint is a perennial plant of the mint family. It has lovely lace-like foliage that releases a pleasant fragrance. Catmint flowers bloom in early summer and can be white, pink, or purple. Catmint’s rapid growth habits are perfect for filling in garden areas and flowing along sidewalks. 

Catmint grows quickly and ideally should be planted from spring until early fall. Plant it in a sunny area with well-drained soil, as a more optimal environment will result in more blossoms and a stronger fragrance. 

3. Balloon Flower 

The balloon flower has become popular because of its disease-resistance and low-maintenance qualities. It produces 2 – 3-inch balloon-like purple, pink, or white flowers that bloom year-round.

This plant thrives in organic, loamy soil that is well-drained. Ensure the soil remains moist. Be careful not to disturb its fragile, fleshy taproots. If you’re looking for something unique, consider using this plant in mixed beds, landscaping borders, and flower pots.

4. Lilac

In colder climates, lilacs are a spring landscape mainstay and are treasured for their sweet fragrance. They’re known for their hardiness and the ease at which they grow. Lilacs are so hardy that they can live for a century or more, often outlasting the homes where they were planted. 

Lilacs prefer loamy, damp neutral to slightly alkaline soil. The soil should also allow adequate drainage to prevent root rot and other diseases. 

Plant your lilac in an area that receives at least six hours of direct sunlight each day. Lilacs will grow well in partial shade, but they will produce fewer flowers. Dwarf lilacs are ideal for small gardens or containers.  

5. Dalmatian Bellflower 

Dalmatian bellflowers are herbaceous perennials with circular green leaves and purple cup or bell-shaped flowers. This plant looks great hanging down the sides of planters or draped along stone walls.

Dalmatian bellflowers should be planted in regular, well-drained soil. Keep the soil damp but be careful not to oversaturate it with water. They grow best in full sun, but they also tolerate slight shade

This plant looks great when planted along pathways, landscape edges, and in rock gardens. It can also grow effectively as a ground cover in smaller, more restricted landscapes.

6. Heliotrope

This shrub can grow to a height of 4 – 5 feet and a width of 6 – 8 feet. It produces deep purple fragrant flowers that bloom in abundance in the spring and autumn.

Heliotrope is excellent for adding purple to flowerbeds and along landscape borders. It also looks great in city and cottage gardens, beach gardens, and in planters. 

Plant heliotrope in damp, biologically rich, well-drained soil. Ensure its soil stays moist. For maximum blooming, place it in full sun, but move it to shade when temperatures become excessively high. 

7. Gladiator Allium 

This plant produces magnificent lavender globe-shaped blooms that are eye-catching in any garden. This unique plant should be placed in direct sunlight; even partial shade will make them sag down. 

Gladiator alliums are drought-tolerant and will grow in a wide range of soil as long as it’s well-drained. And, as members of the onion family, they naturally repel deer and mice.
