Ideal conditions and planting
The sea holly 'Silver Salentino' seedling is an ideal choice for drought-tolerant, steppe parts of the garden or modern gravel beds. It requires a place where the sun hits it for most of the day. The soil should be rather poor and above all perfectly well-draining (sandy, stony). When planting, maintain a spacing of 40 to 50 cm; denser planting could hinder air circulation and the plants would compete. Although the plant is very resilient, water it moderately in the first weeks after planting until it roots into the deeper layers of the soil.
Care during the year and fertilizing
This is a plant for which the "less is more" rule applies. Sea holly requires almost no fertilizing; in overly nutritious soil, it would grow too vigorously at the expense of stem strength and the intensity of the silvery color. Regarding moisture, mature plants are very tolerant of drought. Thanks to its height of 70–100 cm and sturdy stems, it usually needs no support if it grows in full sun in poorer soil.
Usage and winter maintenance
The flowers are very suitable for cutting into fresh bouquets as well as for drying. For drying, cut the stems in full bloom on a sunny day and hang them upside down in a dark, airy place. If you do not harvest the flowers, leave them in the flowerbed over the winter. Although the plant is highly frost-resistant (zone 4a), the dry stems naturally protect the center of the plant and also fulfill an ornamental function in the winter. Remove the old foliage only in the spring. Watch out for voles, which like the roots – in high-risk gardens, consider planting in wire baskets.
Sea holly in a planter or pot
Growing sea holly in pots is possible, although it thrives best in the open ground. If you decide on a container, it must be voluminous and deep enough to accommodate the root system. Use a poorer substrate with a large proportion of sand or perlite so that water drains quickly. In a container, the plant must not stand in a saucer with water, otherwise it will die. It will look very modern on sunny balconies.
