Eryngium Blue Sea Holly is a unique variety for the garden. Its captivating blooms and foliage are a sight to see in bloom. Their leaves and blossoms have an unique look all their own and grow in a range of growing conditions. Their silvery-blue-green stems produce blue cones surrounded by silvery-blue bracts that bloom throughout the summer. These amazing plants are drought tolerant, deer and critter resistant, water-wise and attract butterflies like few other plants do. They are also perfect for cut and dried flowers.

Plant Eryngium in the spring after all danger of frost has passed in a full sun location in moist but well draining soil. Soil preparation: The ideal soil is porous and drains well and yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments (peat moss or ground bark). Spread a 3-4" layer of soil amendment, add fertilizer and incorporate together into the soil to a depth of 10". To plant: Dig a hole 1-2" deep in a sunny (at least 6 hours of direct sun), well drained location. Place the Eryngium in hole with roots pointed down and space 18-24" apart. Cover with soil and water. Mulch in extreme climates.
