Product Information

Full details

The Thompson & Morgan Knautia Macedonica is ideal for gardeners seeking a vibrant, long-blooming perennial for borders and cut flower arrangements. Its key benefit is a remarkably extended flowering season, lasting from summer well into early winter with striking cherry-red flowers. A potential caveat is that the plant's delivered size can vary seasonally, as indicated by pot size rather than fixed height.

FAQs

What is the expected height and spread of this plant?

The plant typically reaches a height of 90-120cm (3-4ft) and develops a rounded, bushy habit. Keep in mind that actual size can vary seasonally.

When is the best time to plant the Knautia macedonica?

The best time to plant is typically in spring or early autumn, ensuring the soil is workable and not frozen.

How often should I water the plant?

Water regularly to keep the soil moderately moist, especially during the first growing season and dry periods. Avoid letting the soil become waterlogged.

Can this plant be grown in a pot?

Yes, it can be grown in a large pot, provided it has good drainage and receives adequate sunlight. Ensure the pot is large enough to accommodate its mature size.

Is this plant suitable for attracting pollinators?

Yes, the flowers are attractive to bees and other beneficial insects, making it a good choice for pollinator-friendly gardens.

What does 'supplied as 1 x 1 litre potted plant' mean for size?

It means the plant is provided in a 1-litre container. The actual above-ground size of the plant will vary depending on the season, as indicated by pot size rather than a defined plant size.

How do I care for the plant in winter?

Knautia macedonica is a hardy perennial. In colder climates, you can cut back the dead foliage in late autumn or early spring to tidy the plant and encourage new growth.

Troubleshooting

Plant is not flowering well.

Ensure the plant is receiving adequate sunlight (at least 6 hours daily) and has been fed during the growing season. Deadheading spent blooms can also encourage more flowers.

Leaves are yellowing.

This could indicate overwatering or poor drainage. Check soil moisture and ensure the planting location does not retain excess water.

Plant appears leggy or weak.

Provide more sunlight if possible. Consider cutting back the plant by about a third to encourage bushier growth and potentially more flowers.

Flowers are fading quickly.

Regular deadheading of spent blooms will encourage the plant to produce more flowers rather than setting seed. Consistent watering and feeding also help maintain bloom quality.

Pros and Cons

Pros

  • Offers a very long flowering period, extending garden color late into the year.
  • The unique cherry red color of the flowers is a rare and attractive feature.
  • Its robust growth habit makes it a great filler for borders.
  • Excellent for cut flower arrangements due to abundant blooms.
  • Low maintenance and easy to care for.

Cons

  • Plant size upon delivery can vary significantly due to seasonality.
  • Requires full sun for best flowering performance.
  • May require staking in exposed or windy locations as it grows taller.

Setup, Compatibility & Care

Planting:

  1. Select a location that receives full sun to partial shade.
  2. Ensure the soil is well-draining; Knautia macedonica dislikes waterlogged conditions.
  3. Plant the 1-litre pot directly into the ground or a larger container, ensuring the top of the root ball is level with the soil surface.
  4. Water thoroughly after planting.

Care:

  • Light: Prefers full sun for optimal flowering, but tolerates partial shade.
  • Watering: Keep the soil consistently moist but not waterlogged, especially during dry spells. Reduce watering once established.
  • Feeding: Apply a balanced plant food once in spring and again in mid-summer during the growing season to encourage continued flowering.
  • Pruning: Deadhead spent flowers regularly to promote new blooms. Cut back the plant in late autumn or early spring to encourage fresh growth.
  • Support: Taller specimens may benefit from staking, especially in windy areas, to prevent flopping.

Compatibility:

This perennial is well-suited for mixed borders, cottage gardens, and pollinator gardens. It pairs well with a variety of plants that have complementary or contrasting colors and bloom times.
