Matthiola

EdibleMedicinalSalt Tolerant

Overview

Old-fashioned flowers prized for their intoxicating clove-like fragrance, stocks (Matthiola) produce dense spikes of double flowers in pastel pinks, purples, whites, and creams. Their scent is strongest in the evening, making them ideal near windows and outdoor seating areas. Evening stock (M. longipetala) is plain by day but releases the most heavenly perfume at dusk.

Stock, scientifically known as Matthiola, is a delightful addition to any garden. This genus of flowering plant belongs to the mustard family, Brassicaceae, and boasts around 50 species, ranging from annuals to biennials and perennials.

Appearance and Distinguishing Features

The flowers of stock plants are the primary draw for gardeners. They come in a variety of colors, including white, pink, purple, and violet. The blooms are known for their sweet fragrance, which can fill an entire garden when several plants are grown together. The leaves of stock plants are typically blue-green and have a slightly glaucous appearance.

Native Range and Habitat

Stock plants are native to the Mediterranean region and parts of central Europe. They thrive in rocky areas, grassy slopes, and disturbed ground, preferring well-drained soil.

Growing Conditions and Care

Stock plants prefer full sun exposure but can tolerate some shade. They need well-draining soil that is not too rich or fertile, as this can lead to lush foliage but few flowers. The plants are drought tolerant once established and do not require regular watering. Deadheading spent blooms can encourage a second flush of flowers.

Uses

Ornamental: Stock plants are primarily grown for their beautiful and fragrant flowers. They make excellent cut flowers and can be used in borders, rock gardens, or containers.

Ecological

Some species of stock, such as M. incana, are known to attract bees and other pollinators, making them valuable in ecological landscaping.

Cultural or Historical Significance

Stock plants have been cultivated for centuries, with their use dating back to ancient Egypt. The genus is named after Italian naturalist Pietro Andrea Mattioli, who first described the plants in his botanical writings in the 16th century.
