Matthiola, or stock, is one of the most fragrant garden plants, especially valued for its evening and nighttime scent as well as for its decorative qualities. Native to the Mediterranean, matthiola has adapted well to Ukraine and is popular both among landscape designers and home gardeners. Depending on the species, matthiola may be an annual, biennial, or perennial crop, but annual forms are most often grown in garden plots because of their fast growth and abundant flowering. Ukraine’s climate, with its distinct seasons, is very well suited to cultivating this crop, especially in the central and southern regions.
One of the main features of matthiola is its need for sufficient light. Although its fragrance is most pronounced in the evening and at night, the plant needs plenty of sun during the day for good growth and flowering. It is best to plant matthiola in open, well-lit areas protected from drafts and strong wind. In Ukraine, it thrives on southern and south-western slopes, in sunny flower beds, and along paths, where it pleases not only the eye but also the sense of smell. With insufficient light, the plants become stretched, lose their compact shape, and bloom much more poorly.
Soil also plays an important role in growing matthiola. It prefers light, well-drained, slightly alkaline or neutral soils. Loam with a high humus content is optimal. In acidic or heavy soils, the plant develops more slowly and is more often affected by fungal diseases. In autumn before planting, the site is dug over and organic matter is added — humus or compost, up to 5 kg per square meter. In spring, 1–2 weeks before sowing, the soil is loosened again and ash or lime is added to reduce acidity if needed. Fresh manure is not recommended, since it promotes the development of blackleg and other diseases. Excessively wet places with standing water should also be avoided — this is especially important in the northern regions and on clay soils.
Matthiola can be grown either by direct sowing in open ground or through seedlings. Both methods have their advantages and can be used depending on climatic conditions and the time available. In Ukraine, especially in the southern and central regions, direct sowing into the soil is used most often, since spring comes early there and warm weather sets in quickly. In the northern regions and during unstable springs, the seedling method makes it possible to achieve earlier and longer-lasting flowering.
Direct sowing is carried out in late April to early May, when the temperature steadily exceeds +12°C. The seeds are sown into prepared furrows 0.5–1 cm deep, with 20 cm between the rows. After sowing, the furrows are carefully covered with soil and lightly firmed. Seedlings appear in 7–10 days. After the first true leaf forms, thinning is carried out, leaving 15–20 cm between the plants depending on the variety. To extend the flowering period, sowing can be repeated at intervals of 10–14 days.
When growing through seedlings, the seeds are sown in late March to early April in containers filled with a light, sterile mix. The containers are covered with film or glass and placed in a warm, well-lit location with a temperature of +18 to +22°C. After the seedlings appear, the cover is removed and the young plants are moved to a windowsill with sufficient light. Pricking out is carried out at the stage of two true leaves, preferably into separate cups, since matthiola does not tolerate transplanting well if the root is damaged. Ten to fourteen days after pricking out, the plants are fed with a weak solution of a complex fertilizer. Seven to ten days before planting in a permanent place, the seedlings are hardened off by taking them outdoors and gradually increasing the time they spend outside.
It is advisable to plant seedlings in open ground in mid-May, once the threat of return frosts has passed. In Ukraine, this timing depends on the region: in the south it is early May, and in the north it is the end of the month. The planting holes are placed 20–25 cm apart, depending on the variety and plant height. A handful of compost or humus can be added to each hole, avoiding direct contact with the roots. The root collar should remain at ground level. After planting, the plants are watered immediately.
Matthiola is a plant that does not require excessive care, but for abundant and prolonged flowering it needs regular watering and weeding. Water when the top layer of soil dries out, avoiding both drought and excessive moisture. During dry periods, watering is done 2–3 times a week, especially during budding and flowering. After watering, the soil should be loosened to prevent crusting, and weeds should be removed. Regular inspection of the leaves for spots, coating, or pests makes it possible to detect problems in time and prevent their spread.
Feeding is carried out 2–3 times per season. The first feeding is given 10–14 days after planting in open ground using a complex mineral fertilizer. The following feedings are applied during budding and active flowering. Fertilizers with a higher phosphorus and potassium content are best, as they stimulate bud formation and prolong the flowering period. Excess nitrogen can cause excessive growth of green mass at the expense of flowers, so it should be used carefully, especially if the soil was already enriched with organic matter in autumn. Matthiola also responds well to ash — it nourishes the plant and protects it from root rots and some pests.
Matthiola is valued not so much for the lushness of its flowers as for their incredible fragrance, which becomes especially pronounced in the evening and at night. The flowers may be single or double depending on the variety and come in a wide range of colors: from white and pink to lilac and purple. Flowering usually begins in June and lasts until mid-September, especially with regular watering and feeding. To prolong this period, it is recommended to remove faded inflorescences so the plant does not waste energy on seed formation. Such pruning stimulates the production of new buds and increases the overall number of flowers.
For continuous flowering, staggered sowing is used — the seeds are sown at intervals of 10–14 days. This makes it possible to obtain plants at different stages of development and ensure a striking succession of blooms. This scheme looks especially attractive in border plantings or along garden paths. It is important to remember that matthiola tolerates transplanting poorly in adulthood, so with the seedling method it is better to use separate cups from the start.
Double-flowered varieties of matthiola are usually sterile and do not produce seeds, so they are propagated only by purchased seed material. Single-flowered forms are capable of self-seeding, but they often lose their varietal characteristics. If you want to preserve a rare variety, it is best to collect seeds only from single flowers that grew at a distance from other varieties, in order to avoid cross-pollination. Mature seed pods are collected in dry weather, dried in paper bags, then the seeds are cleaned and stored in a cool, dry place until the following spring.
Despite its hardiness, matthiola, like other members of the cabbage family, is vulnerable to a number of diseases and pests. The most common problem is blackleg, which is especially dangerous at the seedling stage. It is caused by pathogenic fungi that develop under excessive moisture and poor ventilation. For prevention, sterile soil should be used, overcrowded sowing should be avoided, and the watering regime should be observed. If symptoms appear, the seedlings are treated with fungicides and watering is temporarily reduced.
Other common diseases are fusarium wilt, gray mold, and downy mildew. All of them often arise from excessive moisture, lack of air circulation, and dense planting. Regular thinning, morning watering, treatment with biofungicides, and the use of ash as a preventive measure help avoid most infections. It is very important to observe crop rotation: matthiola should not be grown in the same place every year, especially after other cruciferous crops such as cabbage or radish.
Among pests, the most common are flea beetles, aphids, and cabbage moth caterpillars. Dusting with ash, tobacco dust, or a mixture of ash and lime is effective against flea beetles. Aphids can be controlled with garlic, onion, or chamomile infusions, as well as biological products. Biological treatments and manual removal work well against caterpillars. Additional protection is provided by mulching and by planting repellent plants near matthiola — marigolds, calendula, and mint — which not only deter pests but also harmoniously complement the composition.
Matthiola is a versatile plant that is perfectly suited to open ground, flower beds, pots, and planters. Its fragrance is especially valuable in the landscaping of terraces, balconies, and relaxation areas in the garden. Thanks to its compact size, matthiola can be planted in alpine slides, rabatkas, and mixborders. It looks most impressive in mass plantings — along paths, near benches, gazebos, or at the entrance to the house. It is often combined with crops such as lavender, alyssum, petunia, ageratum, and cineraria — matthiola adds fragrance and enhances the decorative effect of these plants.
For container growing, low-growing matthiola varieties up to 30 cm tall are chosen. The pots should have drainage holes and be placed in well-lit locations such as balconies, verandas, or sunny windowsills. Watering is carried out as the soil dries, and feeding is done every 10–14 days. Care for matthiola in containers is the same as in open ground, only with closer attention to moisture during hot days. After the season ends, the pots are cleaned and prepared for new sowing the following spring.
Collecting seeds is a simple but important step for those who want to continue growing a favorite variety. Seed pods form on the lower part of the shoots after flowering. Mature ones are brown and open easily when pressed. They are collected in dry weather, dried in paper bags in a ventilated room, then the seeds are cleaned and stored in a dry, cool place until the next season. With proper care, matthiola will become a fragrant highlight of your garden every year.
