Echinops Ritro, commonly known as ‘Small Globe Thistle’, is a perennial herbaceous plant that belongs to the Asteraceae family. The plant is native to Europe, Central Asia, and North Africa and is widely cultivated as an ornamental plant in gardens around the world.

This Echinops is a low-maintenance plant that typically grows up to 1 metre in height and spreads up to 1/2 metre in width. The plant has a clumping habit and produces a basal rosette of spiny, lobed leaves that are green-grey in colour. The leaves are deeply divided and have sharp spines along the edges, making it an unappealing snack for animals.

In mid to late Summer, the plant produces large, round, spiny flower heads that are a bright, metallic blue and are held on strong, sturdy stems that rise above the foliage. The flowers are pollinated by bees and butterflies, making this a valuable addition to any pollinator garden.

This is a hardy plant that thrives in full sun to partial shade and is tolerant of a wide range of soil conditions. The plant prefers well-drained soil and is drought tolerant once established. It can be propagated by seed or by dividing mature plants in the Spring.

Overall, this is a versatile and attractive plant that adds colour and texture to any garden. With its stunning blue flowers, spiny foliage, and low-maintenance requirements, it is a great choice for gardeners looking to add a unique and interesting plant to their landscape.

How to care for your Echinops Ritro

  • Soil: Prefers well-draining soil that is rich in organic matter. It can tolerate a wide range of soil types, but it is essential to avoid waterlogged soil, as this can lead to root rot. If your soil is heavy or clayey, you can improve drainage by adding sand, perlite, or other coarse materials.
  • Watering: It is drought-tolerant once established, and excessive watering can cause root rot. Water the plant deeply once a week during dry spells or when the top inch of soil feels dry. Avoid overhead watering, as this can lead to fungal diseases.
  • Sunlight: Thrives in full sun but can tolerate partial shade. Ensure that the plant gets at least 6 hours of direct sunlight each day for best growth.
  • Fertiliser: Does not require fertiliser, but a light application of balanced fertiliser in early Spring can promote healthy growth and blooming. Avoid over-fertilising, as this can lead to lush foliage and fewer flowers.
  • Pruning: Does not require regular pruning, but deadheading spent flowers can promote a more extended blooming season. Cut the spent flower stems back to the base of the plant or where they meet the foliage.
