Pinks and dianthus are often used interchangeably, but they refer to different aspects of the same plant family. Pinks are a common name for certain types of dianthus, known for their fringed petals and spicy fragrance. Dianthus is the botanical name for a genus that includes carnations, sweet williams, and pinks, each with unique characteristics.

What Are Pinks and Dianthus?

Understanding the Basics of Dianthus

Dianthus is a genus of flowering plants in the Caryophyllaceae family, comprising over 300 species. Known for their vibrant colors and sweet fragrance, dianthus plants are popular in gardens worldwide. They are characterized by their narrow, linear leaves and five-petaled flowers, which often have a fringed or serrated edge.

• Common Types of Dianthus:
  • Carnations (Dianthus caryophyllus): Known for their large, showy blooms and are often used in floral arrangements.
  • Sweet Williams (Dianthus barbatus): Biennials with clusters of small flowers, loved for their bright colors.
  • Pinks (Dianthus plumarius): Perennials with a spicy fragrance and fringed petals, often used in rock gardens.

What Makes Pinks Unique?

Pinks specifically refer to certain species within the dianthus genus, particularly those with fringed petals that resemble pinking shears’ cut edges. These plants are typically low-growing, forming dense mats, and are well-suited for borders and rock gardens. The name "pinks" comes from the jagged edges of the petals rather than their color.

• Characteristics of Pinks:
  • Height: Generally low-growing, around 6-12 inches.
  • Fragrance: Known for their clove-like scent.
  • Flowering Season: Bloom from late spring to early summer.

How to Differentiate Between Pinks and Other Dianthus?

Identifying Features

While all pinks are dianthus, not all dianthus are pinks. Here are some distinguishing factors:

• Petal Edges: Pinks have distinct fringed or serrated petal edges.
• Growth Habit: Pinks are typically low-growing, while other dianthus can vary in height.
• Flower Clusters: Sweet williams have clustered blooms, unlike the solitary flowers of pinks.

Practical Examples

For instance, if you see a dianthus plant with a large, solitary bloom and smooth petals, it’s likely a carnation. Conversely, if the plant forms a dense mat with fringed petals and a spicy scent, it’s likely a pink.

Caring for Pinks and Dianthus

Growing Conditions

Both pinks and dianthus thrive in similar conditions:

• Sunlight: Full sun to partial shade.
• Soil: Well-drained, alkaline soil.
• Watering: Moderate watering, allowing the soil to dry out between sessions.

Maintenance Tips

• Deadheading: Remove spent blooms to encourage more flowers.
• Pruning: Trim back after flowering to maintain shape and promote growth.
• Fertilization: Use a balanced fertilizer in early spring.

What Is the Best Time to Plant Dianthus?

The best time to plant dianthus is in the spring after the last frost. This allows the plants to establish before the heat of summer. If planting in the fall, ensure it’s early enough for roots to develop before winter.

How Long Do Pinks Bloom?

Pinks typically bloom from late spring to early summer. With proper care, some varieties may continue to flower sporadically throughout the growing season.

Are Pinks and Carnations the Same?

While both are part of the dianthus genus, pinks and carnations differ. Pinks are usually smaller with fringed petals, while carnations have larger, smoother blooms.

Can Dianthus Grow in Pots?

Yes, dianthus can thrive in pots, provided they have adequate drainage. Use a well-draining potting mix and ensure the container receives enough sunlight.

How Do You Propagate Pinks?

Pinks can be propagated through division, cuttings, or seeds. The easiest method is division, which involves separating clumps in early spring or after flowering.

Summary

Understanding the difference between pinks and dianthus is essential for any gardening enthusiast. While all pinks are a type of dianthus, they are distinguished by their fringed petals and compact growth. By recognizing these features, you can better appreciate the diversity within the dianthus genus and make informed choices for your garden. Whether you’re looking to add color to a rock garden or create a fragrant border, both pinks and other dianthus varieties offer beautiful options.
