Thompson and Morgan Eryngium Planum Blue Hobbit Plant Pot 9cm 3 Pack

In midsummer, you will see sprays of nearly 100 inky-blue flowers. These are perfect for borders and patio pots and can be grown in many types of different soil types. Grow sea holly plants on light, well-drained soil in full sun. Eryngium plants particularly dislike cold, wet soil in winter, which may cause the crown to rot. If planting on heavy soils, dig in plenty of coarse grit to improve drainage prior to planting. Feed and water regularly throughout the growing season until plants are fully established. Leave faded eryngium flower heads in place until spring to benefit from the winter interest they will add to your borders. In cold, wet soils, use a cloche to protect the crown of the plant from winter rainfall. Lift and divide overcrowded clumps of eryngium in spring. Only lift it when necessary, as sea holly can be slow to re-establish. Product Specifications: Hardy. Position: Full sun. Height: Up to 30cm. Spread: Up to 30cm when fully established. Images shown are for guidance only of the expected results from plants upon maturity. Different growing conditions might vary the results. Image may be included for illustration of supply, but can vary due to seasonality changes (e.g. deciduous plants lose leaves in colder months).
