Grow Your Secret Garden Eryngium Alpinum Superbum Seeds- Alpine Sea Holly

Product Information

Watering: Water the plants regularly during the growing season, but make sure you’re not overwatering. Eryngium does not like to sit in wet soil. Once established, it is quite drought tolerant. Sedum: Sedums have fleshy, succulent-like leaves and clusters of star-shaped flowers. Their rounded form makes a nice contrast to the spiky Eryngium, and they also share similar growing conditions. Cottage and Coastal Gardens: Sea Holly is a traditional component of cottage gardens and also adapts well to coastal gardens due to its salt tolerance. Pair it with other cottage garden favorites like roses, delphiniums, or lavender for a classic look. Yarrow (Achillea): With its feathery foliage and flat-topped clusters of flowers, yarrow provides a strong contrast to the spiky form of Eryngium.

The safety of our visitors and staff remains our top priority. In England, wearing a face covering is a personal choice, although they are recommended in crowded and enclosed places. Eryngium giganteum– Caucasus – The cylindrical capitula, up to 6 cm long, bloom in summer. The flowers, of pale green colour, while opening, become then steel blue. The bracts, up to 6 cm long, of silvery grey colour, have spiny margins. They have the same exigencies as the previous species. The variety ‘Silver Ghost’ has narrow bracts of silvery colour. Attracts Pollinators: Sea Holly is an excellent plant for attracting pollinators. Its nectar-rich flowers are popular with a variety of beneficial insects, including bees and butterflies. This can help support local ecosystems and contribute to a biodiverse garden. All eryngiums form basal rosettes, have leaves which are spiny with silvery white veins, and have crowded thistle-like umbels of stalk-less flowers on branched stems. Sea Holly can be a striking addition to various garden designs due to its unique color, texture, and structural form. Here are some ideas on how to integrate it into your garden design:The stems are glabrous, erect, ramified in the upper part, of bluish green colour. In the central part they have some longitdinal violaceous striations. The fruit is an ovoid spinescent achene of 4-6 mm. The root system is taprooted, deep, compact, well developped. by eelworms. Powdery mildews and root rot can be a problem in wet soil conditions. Propagating Eryngium Eryngium alpinum is cultivated as an ornamental plant for its blue and purple flowerheads. It requires dry, well-drained soil and full sun. [4] Conservation [ edit ] Eryngium (e-ring-e-um or er-in-je-um) is a genus of flowering plants with over 250 species that, believe it or not, are in the carrot family (Apiaceae). Common names include eryngo, spiny coriander, culantro and the more popular sea holly (though the genus is not related to the true hollies, Ilex). People also often think it is a thistle (Cirsium)! Apparently you can eat the roots or use them as flavouring, although I've never tried (I guess it is in the carrot family after all.....)

Ornamental Grasses: The spiky form of Eryngium contrasts well with the flowing, feathery forms of ornamental grasses. Try Panicum, Stipa, or Miscanthus for an interesting textural contrast. Salvia: With their spires of flowers, salvias can echo the form of Eryngium but provide a softer texture. Look for varieties with purple or blue flowers for a cool-colored theme, or contrast with red or pink varieties. The Eryngium alpinum is not particular for what the substratum is concerned. In nature it grows equally on limestones, dolostones, calcareous schists, siliceous schists, sandstones. The ideal soil, however, has a pH tending to basic, is moderately fertile, well drained (it fears water stagnations especially during the cold season), averagely humid, especially during the phase of growth. The epithet 'alpinum' means of mountains at altitudes usually above timberline. It is commonly called alpine sea holly - which makes me laugh - sea? alpine? really?.Excellent choice for gravel gardens, cottage gardens and coastal gardens. May be planted as a single specimen or in groupings. Perfect for cut or dried flower arrangements too! These types of eryngium develop airy heads of green-white flower thimbles. These are widely spaced like an atomic model atop tall stems, above an attractive mass of long, slender green leaves. The yellow-tinged ivory white sea holly is a prolific and enchanting flowering choice. Modern and Architectural Gardens: Sea Holly’s structural form works well in contemporary, minimalist garden designs. Pair them with other architectural plants like agaves or tall grasses, or use them to add texture to a garden full of sleek, smooth-leaved plants. The seed heads can be left-on overwinter for architectural interest. Cut the plants down to ground level in early spring. Pests and Diseases Unique Aesthetics: Eryngium plants stand out with their spiky texture, distinctive thistle-like flowers, and sometimes blue or silvery tones. They can act as a focal point in your garden and draw the eye.
