FREE: 10 Blue Star Holly Seeds

The listing, 10 Blue Star Holly Seeds has ended.

Eryngium plants, also known as sea holly flowers, make striking additions to the garden. Mostly native to Europe and the Mediterranean, these plants generally grow anywhere from 18 to 36 inches tall with a one-foot spread. Their green or silvery-blue stems give way to green or blue cones surrounded by spiky silver, white, green, blue or violet bracts, which bloom from summer throughout fall.

Sea holly plants are tolerant of drought, winds, salt sprays and sandy soils. They can be used as specimen plantings, in beds and borders, or butterfly gardens. In addition, these plants make excellent dried flowers.

Growing Eryngium plants is easy. All types will thrive in full sun and moist soil with good drainage. In fact, they actually prefer sandy soil. The long taproot, however, allows the plant to tolerate poor soil conditions and drought.

Because of their taproot, locate sea hollies somewhere permanent, as they do not transplant easy. Place young plants in holes that are a few inches wider and deeper than their current root system.

Seeds can be sown directly in the garden, though they may not bloom the first year. The seeds require a warm moist stratification for one month followed by one month of cold moist stratification.
