Sowing Instructions:
Sow Eryngium Leavenworthii seeds indoors in early spring, around 6-8 weeks before the last expected frost. Fill seed trays or pots with a well-draining, seed compost mix, and scatter the seeds thinly over the surface. Lightly press the seeds into the soil but do not cover them, as they need light to germinate. Keep the compost moist and maintain a temperature of around 18-20°C for optimal germination, which should occur in 10-14 days. Once the seedlings have developed enough, harden them off and transplant them to a sunny, well-drained spot outdoors, spacing the plants 30-45 cm apart to allow them room to grow.

This perennial typically grows to a height of 60-90 cm, with striking blue flowers blooming in mid to late summer. Eryngium Leavenworthii thrives in dry, well-drained soils and requires minimal maintenance, making it an ideal choice for water-wise or low-maintenance gardens. Its unique, spiky appearance is perfect for adding structure to flower beds, rock gardens, or wildflower meadows. Not only does it bring visual interest, but it also attracts a variety of pollinators, making it a great addition to a wildlife-friendly garden. Add Kew Flower House Eryngium Leavenworthii for a bold, textured look that will stand out through the seasons.
