This perennial plant can also be grown as an annual in cooler climates or as a biennial, with the first year devoted to growing foliage and the second year to producing flowers.

Water the scabiosa regularly, especially during the first year and in drought-like conditions, but be cautious not to overwater, as it is susceptible to root rot in wet soils.


Pincushion flowers thrive best in full sun, which means they need at least six hours of direct sunlight daily. This is especially crucial in cooler climates where the high temperatures of full sun can benefit the plant.

In warmer sites, however, they can tolerate light afternoon shade. It’s important to note that despite their need for sunlight, pincushion plants in extremely hot regions may benefit from some protection from the intense afternoon sun.

This balance is essential to ensure the vibrant blooms and healthy foliage of both annuals and perennial varieties.


The pincushion plant thrives best in well-draining soil. It can tolerate a variety of soil types, including clay soil, as long as the soil doesn’t become waterlogged, which can lead to the development of slugs and other harmful organisms.

In wet soils, the plant’s wiry stems may become weak, impacting its upright habit. In drought-like conditions, the pincushion plant may need more frequent watering to keep its foliage healthy.

Adding organic matter to the planting site can help improve the soil’s drainage, which is beneficial for the plant’s overall health.


Scabiosa plants have a preference for well-draining soils, making them more tolerant of drought-like conditions. However, during the first year of establishment, it’s crucial to ensure they receive adequate water, particularly in warmer sites.

In high temperatures, these perennial varieties may require more frequent watering, but it’s essential to avoid waterlogging the soil, as this can lead to the development of diseases and attract slugs.

Monitoring the foliage for any signs of wilting during dry periods can be a good indicator of when to water your pincushion plants.

Temperature and Humidity

Pincushion flowers thrive best in a wide range of temperatures but generally prefer warmer sites. They can endure mild winters and high temperatures, especially when they are in full sun.

In cooler climates, these annuals may need a little extra care to survive the threat of frost. They are not particularly demanding when it comes to humidity, but they do prefer well-draining soils to prevent root rot in wet conditions.

In drought-like conditions, regular watering is necessary to keep the plants healthy and producing their stunning pincushion flower blooms.


Pincushion flowers, also known as Scabiosa, have modest fertilizer requirements. For the perennial varieties, it’s beneficial to amend the soil with compost or a balanced slow-release fertilizer in the first year and then annually in early spring.

This helps promote strong stems and vibrant blooms. However, for the annual types, a single application at planting time suffices.

Over-fertilization should be avoided as it can lead to excessive foliage growth at the expense of flowers. Always water the Scabiosa after applying fertilizer to help distribute the nutrients to the root zone.


Pruning is an essential aspect of maintaining the pincushion flower’s health and promoting its vibrant blooms. The process of deadheading, or removing spent pincushion flower blooms, not only tidies up the plant but also encourages the production of new flowers.

In the early spring of the first year, prune back any wiry stems to promote an upright habit and bushier growth. During late spring or after the first flush of blooms, trim the long stalk to maintain the plant’s shape and stimulate further flowering.

In cooler climates, where there is a threat of frost, it’s best to leave the faded flower heads on the plant to provide some protection to the foliage. Come the first frost, you can cut back the entire plant in preparation for the next growing season.

The removed parts of the pincushion plant can be a good addition to a dried flower arrangement.


Pincushion flowers, or scabiosa, have varying overwintering needs depending on the specific variety and the climate.

In cooler climates, these plants can be treated as perennials, with their foliage left to overwinter. However, in areas with harsh winters, it’s advisable to provide some protection, such as a layer of mulch over the root zone.

The threat of frost should be considered, and if severe, the wiry stems can be cut back to the leaf joint. A first frost is usually the signal for this practice.

In milder winters, these lovely plants may continue to bloom until late into the season, adding a charming touch to your garden even after the first year of growth.

How to Plant Pincushion Flower From Seed

Step 1: Choose the Right Location

Pincushion flowers prefer full sun but can tolerate partial shade, especially in warmer sites. They also need well-draining soil, as they don’t like wet feet.

Step 2: Prepare the Soil

Pincushion flowers can adapt to various soil types, including clay soil. However, if your soil is heavy, consider adding some organic matter to improve its drainage.

Step 3: Sow the Seeds

In early spring, sow the seeds of the pincushion plant. You can start them indoors 6-8 weeks before the last expected frost or sow them directly in the garden after the threat of frost has passed.

Step 4: Care for the Seedlings

In their first year, pincushion flowers will form a rosette of foliage. Deadheading the blooms can encourage more flowers and prevent the plant from self-seeding.

Step 5: Transplant the Seedlings

In late spring or early summer, transplant the seedlings to their permanent location, spacing them according to their mature size.

How to Propagate Pincushion Flower

Step 1: Choose the Right Time

Propagation of pincushion flowers can be done in the early spring, as this is the time when the plants are just beginning to come out of dormancy and are starting to grow.

This step is crucial as it ensures that the plants have enough time to establish themselves before the threat of frost in cooler climates or before the high temperatures in warmer sites.

Step 2: Prepare the Plant

Using a sharp, clean pair of pruning shears, cut a healthy, non-flowering stem from the pincushion plant. Look for a stem that has several sets of leaves and is free from any signs of disease or damage.

Cut the stem just below a leaf joint, which is the point on the stem where a leaf meets the main stem. This is where the new roots will emerge.

Step 3: Prepare the Potting Medium

Fill a small pot with a well-draining potting mix. A mix of equal parts peat moss, perlite, and vermiculite works well for pincushion flowers.

Water the potting mix until it is evenly moist but not waterlogged. Allow any excess water to drain away before proceeding to the next step.

Step 4: Plant the Cutting

Dip the cut end of the pincushion flower stem into a rooting hormone powder to encourage root development. This step is optional but can help speed up the rooting process.

Make a hole in the potting mix with a pencil or your finger and gently insert the cut end of the stem into the hole. Press the potting mix around the stem to hold it upright.

Step 5: Provide the Right Conditions

Place the pot in a warm, bright location out of direct sunlight. Keep the potting mix consistently moist but not waterlogged, as excessive moisture can cause the cutting to rot.

You can cover the pot with a plastic bag or a clear plastic dome to create a mini greenhouse effect and help maintain high humidity around the cutting.

Step 6: Monitor and Care for the Cutting

Check the cutting regularly for signs of new growth, such as fresh leaves or shoots. This is an indication that the cutting has successfully rooted.

Once the cutting has developed a healthy root system, it can be transplanted into a larger pot or directly into the garden. Be sure to acclimate the new plant to outdoor conditions gradually to prevent transplant shock.

How to Pot or Repot Pincushion Flower

Step 1: Choose the Right Pot and Soil

When potting or repotting your pincushion flowers, it’s essential to select a pot with proper drainage to ensure the well-being of the plant. Pincushion flowers prefer well-draining soil, and for those in cooler climates, a pot can be advantageous for moving the plant indoors when the threat of frost looms.

The soil should be fertile and well-draining, as pincushion flowers do not thrive in wet soils. In some cases, where the natural soil is not ideal, you may need to amend it with sand or perlite to improve drainage.

In warmer sites, where the threat of frost is minimal, pincushion flowers can be planted directly into the ground, as long as the soil is well-draining. These plants can tolerate clay soil, but it must be well-draining to prevent waterlogging.

Step 2: Plant the Pincushion Flower

In early spring, after the threat of frost has passed, plant your pincushion flowers in the chosen location. These plants prefer full sun, although they can tolerate some light shade, especially in regions with high temperatures.

Dig a hole slightly larger than the root ball of the plant and place the pincushion flower inside. Fill in the hole with soil, pressing gently to remove air pockets, and water thoroughly.

Step 3: Care for Your Pincushion Flowers

Pincushion flowers are relatively low-maintenance plants, but they do benefit from some care to ensure abundant blooms. In their first year, these plants may not produce as many blooms as in subsequent years, so be patient.

Regular deadheading is essential to encourage continuous blooming. This involves removing spent blooms by pinching them off at the leaf joint to promote the development of new flower buds.

Pincushion flowers are also good candidates for dried flower arrangements, as their blooms retain their color and form well. To use them in dried arrangements, simply cut the long stalks of the blooms and hang them upside down in a dry, airy location until fully dried.
