Santolina varies in height from 0.1 to 0.6 meters. On the surface of the pinnate or simple (in some cases long) leaf plates is a fluff of light grayish coloration. Thin stems reach 10-25 centimeters above the leaves; their upper part contains flowers in yellow or white dense inflorescences of a ball shape, about 20 mm across.

Both the inflorescences and foliage are fragrant because they also contain essential oils. Flowering is from June to August. This highly ornamental crop is grown on slopes, rubble beds, and also in stony gardens.

What time to plant

When planting santolina, it is recommended to choose a well-lit open area that has protection from wind.

If grown in a shaded area, the bushes become elongated, lose their shape and look loose and untidy. Suitable soil for planting should be moderately dry, and also well permeable to water and air. If there is stagnant moisture in the soil, the bushes will quickly die. Therefore, damp clay soil is not suitable for growing santolina. On poor soils, the flowering of this plant is the most lush.

If it is grown on fertile soil, however, the bush will grow strongly, but it will bloom sparingly. The best way to grow this culture is a neutral stony or sandy loam soil. Also note that the groundwater should be fairly deep. before planting, the ground on the selected site should be recultivated. If the soil is heavy, during digging it should be mixed with crushed or fine sand to improve its drainage.

Santolina is grown through seedlings. Sow the seeds in the last days of February or first days of March. However, before sowing the seeds, they must be conditioned by placing them in the vegetable compartment of a refrigerator for 4-8 weeks.

Seeding rules

Sow the seeds in boxes filled with a light slightly damp mixture. The seeds should be covered with foil on top and then placed in a warm, well-lit place.

The first seedlings should appear 15-20 days after sowing. Sprouts need exactly the same care as for the seedlings of other plants. Prick seedlings produced after they begin to form the second or third true leaf plate, for this use individual peat-mulch pots or cups. After the plants will get stronger, they need to harden, and then transplant into open soil, it is done in the last days of May or early June. Planting is done on a rainy day or in the evening after sunset.

The size of the planting holes should be large enough to accommodate the root system of the plants taken together with the root ball. Water the planted plants with very little water. After moistening, any holes in the soil should disappear.

Garden care for santolina

Growing santolina in your garden is quite easy. You do this by providing your shrubs with plenty of timely, moderate watering, loosening the soil near the plants, removing weeds, feeding, cutting off wilted racemes and preparing the plants for winter in good time.

How to water and feed

The watering should be systematic and moderate. This plant is very drought-resistant. If it rains regularly during the summer, shrubs can do without watering. However, during a prolonged dry period, they will need systematic watering. If the stems of this plant turn yellow in the middle of the summer, stagnant moisture in the root system is to blame.

To correct this, you should not water the flowers for a while. Also note that watering should only be done when the top layer of soil has dried out well.

Feeding Santolina is done during intensive growth once every 7 days. Mineral fertilizer solution with a small amount of nitrogen should be applied from the spring after intensive bush growth begins. In August, it is necessary to stop fertilizing the soil.

The nutrient solution should have a very weak concentration, as the presence of large amounts of nutrients in the soil is extremely detrimental to flowering.

How to propagate and transplant

If you grow Santolina in the same place without transplanting, then its degeneration begins. Therefore, the shrubs must be replanted every 5 or 6 years in the springtime. During transplanting, the bush should be divided as well.

The bushes should be taken out of the ground and divided into parts, taking into account that each part should have stems and a part of the rhizome.

The cutting places should be covered with crushed charcoal. Seedlings are planted in planting holes, which should be prepared in advance. They are buried in the soil to the place where the branching of the stem begins. In the autumn the bushes are recommended to be dipped high, thanks to this by the time of replanting the bush will form young branches.

That culture can also be propagated by cuttings.

They are harvested in March, for this purpose the shoots of the current year should be cut from the bush. The cut places are dipped in a solution of a product that stimulates the formation of roots, then the cuttings are planted in sand, and the top is covered with film. After the young leaf plates begin to grow on the cuttings, they should be planted in individual containers. They have until June to grow and get stronger, after which they will be planted permanently.

Wintering

When the plant finishes flowering in August, the stems will need to be shortened by 2/3 length.

This will keep the shape of the bush neat and it will not fall apart. If you grow it as an herbaceous or herbaceous plant, remove the inflorescences before they wilt. Santolina is not very frost-resistant and can die during frosty winters if grown in the middle latitudes. To avoid this, bushes must be covered. To do this from above, they must be covered with a wooden box of large size, which is covered with spunbond, ruberoid, lutrasil or film.

The covering material should be secured with something heavy, such as bricks, otherwise it can be carried away by the wind. However, before placing the box, the surface of the ground near the bush is covered with a layer of needles, lapnik or sand mixed with wood ash. In the spring time, the cover should be removed, and after the snow cover descends, the surface of the plot is covered with compost mulch. Some gardeners take the santolina out of the ground for the winter and plant it in a pot, which is placed in a cool room. In the spring it is planted again in the garden.

Diseases and pests

Santolina is very resistant to diseases and pests. However, if there is stagnant water in the soil, it will cause rot on the root system. In the case where the shoots become yellow early, you can be sure that this is due to stagnant water in the soil. Bushes should be drenched with a solution of fungicidal preparation, then they are not watered for some time. After a while, the plants will be beautiful and healthy again.

If the bushes grow in a shady place, this, too, can cause problems with them. Even though this crop is drought-resistant, it still needs to be moistened systematically, otherwise it may die in parched soil.

Santolina varieties and varieties with photos and names

Gardeners grow 5 or 6 types of Santolina, each with its own flaws and advantages.

Santolina neapolitana

This type is the tallest and can grow up to 100 cm tall. This species has the dwarf varieties Prittie Carol and Weston, which reach a height of only 16 centimeters.

The inflorescences are ball-shaped and yellow in color. They look spectacular against the green background of the dissected leaf plates. Since this species is heat-loving, it is most often cultivated in an alpine greenhouse.

Santolina pinnata (Santolina pinnata)

The bush is about 0.6 meters tall.

The length of the narrow leaf plates is about 40 mm. The long flower stalks have globular, cream-colored inflorescences.

Santolina greenish, or greening (Santolina virens)

This species is the most hardy, being able to withstand frosts as low as minus 7 degrees. This species, unlike the others, has pinnately dissected openwork leaf plates of green color. Thanks to this, from a distance the bush can be misted for a dense pale green fog.

The leaves and young shoots of this plant are often used as a condiment to dishes. The white milky inflorescences are globular in shape.

Santolina elegans (Santolina elegans)
