Valerianella coronata: complete guide

Overview

Valerianella coronata, commonly known as crowned cornsalad or crowned mache, is an elegant wild salad green native to the Mediterranean region. This plant is renowned for its characteristic crowned fruits that stand above the foliage like tiny crowns. The plant has been traditionally used in salads and as a wild green, and continues to grow in many Mediterranean gardens today.

Crowned cornsalad is an annual plant reaching approximately 20 to 40 centimeters in height. It grows rapidly and forms neat rosettes of soft, dark green foliage. The plant is ideal for naturalistic gardens and for those who enjoy wild greens.

Appearance and Bloom

Valerianella coronata grows in a compact rosette with feathery, dark green leaves. The foliage is soft and has a subtle aromatic flavor. During the April to May season, small light blue to purple flowers appear in clusters. After flowering, characteristic fruits develop with their distinctive crown-like appendage.

The fruits are unique and give the plant its name. They measure approximately 3-5 millimeters and feature a striking crown-like structure at the top. This makes Valerianella coronata an interesting plant for bird lovers and natural garden settings.

Ideal Location

Crowned cornsalad thrives best in sunny to partially shaded locations. In the Mediterranean region, it commonly grows on dry hillsides and among rocks. In northern gardens, this plant works well in borders and wildflower meadows. Ensure the plant receives sufficient light, though it also tolerates partial shade well.

The plant also grows well in containers on balconies or terraces, provided light is reasonably adequate.

Soil

Valerianella coronata requires poor to moderately fertile soil. This suits the plant's natural character well. A mixture of garden soil and sand works well. The soil pH can range from 6.0 to 7.5. The plant tolerates dry soil well and dislikes heavy, wet clay.

Ensure good drainage to prevent root rot. If you have heavy soil, add sand to improve structure.

Watering

Crowned cornsalad is drought-tolerant and requires moderate water. During the growing season, water when the soil feels noticeably dry. Once established, this plant requires little supplemental water. However, ensure newly planted specimens don't completely dry out during hot periods.

During winter when the plant is actively growing, water more regularly. Avoid waterlogging, as this harms the plant more than drought.

Pruning

Crowned cornsalad requires virtually no pruning. Let the plant grow in its natural form. Only remove wilted foliage and dead tips. The plant gains much of its charm from its natural growth habit.

After flowering, you can let the plant set seed for birdfood, or cut off flowering tops to extend the harvest of young leaves.

Maintenance Calendar

March: Sow seeds directly in ground. Pre-soaking often isn't necessary.

April to May: Plant develops rapidly. Monitor water regularly.

May to June: Flowering and fruiting. Allow some plants to set seed.

July to September: Plant may continue flowering and setting seed. Provide adequate water during hot periods.

October to February: Plant becomes less active. Minimal care needed.

Winter Hardiness

Valerianella coronata is an annual plant. In temperate climates, the plant typically doesn't survive winter. However, in milder years, some plants may overwinter. In the Mediterranean region, this is more likely. To be certain, resow seeds in spring.

Companion Plants

Valerianella coronata looks attractive in mixed borders with other wild greens and flowers. Combine with other Mediterranean plants such as lavender, sage, and other herbs. In a wildflower meadow, this plant creates a natural appearance. The small flowers attract bees and butterflies.

Conclusion

Valerianella coronata is a charming plant for nature lovers and vegetable growers. Its characteristic crowned fruits make it an interesting element in the garden.
