Eryngium alpinum 'Superbum' Seeds

Eryngium are hardy vigorous plants with strong stems, metallic silver-grey foliage and plenty of beautiful egg shaped violet blue flowers. The Sea Holly's flowers are striking in the garden where their colour and form provide contrast to the more usual mounds and spires of summer flowers. Excellent for wildlife. Attracts Bees, Butterflies and Ladybirds. Excellent Cut Flower and lovely in large containers too.

Eryngium are brilliant plants because they are very long lived, easy to grow and super hardy. They provide a good show in the garden, they're great for container planting, they are full of nectar for insects and to top it all produce masses of flowers for picking. What's more they are perennial. Leave the stems and foliage after flowering, they are very attractive throughout winter months and provide homes for hibernating insects. Cut back in early spring, give them a good mulch of organic matter and they'll regrow to flower again.

GenusEryngium alpinum 'Superbum'
CommonNameSea Holly
Plant TypeHardy Perennial. Cut Flower.
Height & Spread75-90cm tall x 60 wide (2.5-3 feet tall x 2 feet spread)
Sow SeedsSow in late summer/autumn or January/February/March covering very lightly with compost. Eryngium needs a period of cold moist stratification and germinates at 10-16°C in 30-90 days so patience is required. It's worth it though! Allow seedlings to grow until well established then pot on into 9cm pots and grow on until it's warm enough to plant outdoors.
Plant OutPlant out after the last frosts from May onwards. Once plants are established they are hardy all year round to -10 to -15°C.
Conditions RequiredEryngium prefers moist but well drained soil and a sunny spot. Water thoroughly in dry spells.
Flower ProductionMasses of blooms produced from July to October. Eryngium flowers in the second year, approximately 9 months after sowing the seeds. Cut the flowers, deadhead and feed regularly to keep flower production going.
PickingFor cut flowers pick regularly to encourage repeat flowering. It's best to pick early in the morning or in the cool evening and stand them in deep water for a few hours before arranging. Long lasting cut flower (up to two weeks) and can be dried too.
Planting CombinationsEryngium are some of the most architectural and long lived perennial flowers that you can grow. You will be amazed at how many flowers are produced. They make a great show on their own and with other summer flowering perennials such as Achillea millefolium, Echinops ritro, Geranium pratense, Agastache 'Astello Indigo' and shrub roses in a traditional herbaceous border.
