Stock flowers are among the most loved cool-season blooms in American gardens and floral arrangements. Known for their rich fragrance, soft petals, and tall clustered stems, stock flowers bring both beauty and a sweet scent to landscapes and bouquets. Whether you are planning a home garden in the USA or arranging fresh-cut blooms for indoor décor, understanding the stock plant can help you make the most of this classic flowering species.
The botanical name of stock flower is Matthiola incana. It belongs to the mustard family, Brassicaceae, which also includes cabbage and broccoli. Despite being related to vegetables, the stock plant is grown mainly for ornamental purposes because of its vibrant blooms and pleasant fragrance.
What Is a Stock Flower?
A stock flower is a cool-weather annual or biennial flowering plant known for its dense spikes of blooms. The flowers grow in tall clusters and appear in a wide range of colors, including white, pink, purple, lavender, red, and cream. Among them, the white stock flower is especially popular for weddings and formal events due to its clean, elegant appearance.
Stock flowers are often described as:
-
Fragrant blossoms
-
Upright flowering stems
-
Soft, ruffled petals
-
Long-lasting cut flowers
Because of their strong scent, they are frequently compared to other fragrant blooms such as Lilium (lilies) and Dianthus. However, stock flowers have their own distinct spicy-sweet aroma that makes them stand out.
Origin and Botanical Background
The matthiola incana plant is native to the Mediterranean region but has become widely cultivated across the United States. It thrives in cooler temperatures and is often grown during early spring or fall in many U.S. climate zones.
The name “Matthiola” honors the Italian botanist Pietro Andrea Mattioli. Over time, the plant adapted well to different soil conditions and is now common in home gardens, commercial flower farms, and floral markets across the country.
Popular Varieties of Stock Plants
There are several types of stock plants available in the U.S. market. These varieties differ in height, bloom density, and flower color. Some grow tall for cutting gardens, while others remain compact for containers.
Common types of stock flowers include:
-
Ten-week stock (grown as annuals)
-
Biennial stock (flowers in second year)
-
Column stock (single tall stems)
-
Spray stock (multiple branching stems)
White stock flower varieties are especially valued for floral arrangements. Soft pink and lavender stocks flowers are also widely used in seasonal bouquets and spring décor.
Physical Characteristics of the Stock Plant
The stock plant has a sturdy stem and narrow gray-green leaves. Its flowers grow in tightly packed clusters along upright spikes. Each bloom has four petals arranged in a cross-like shape, typical of the Brassicaceae family.
Key features of stock flower:
-
Height: 1 to 3 feet tall
-
Bloom time: Spring to early summer
-
Fragrance: Sweet and clove-like

Because of their structured vertical growth, stock of flowers adds height and texture to flower beds and mixed borders.
Growing Stock Flowers in the USA
Stock flowers perform best in cooler climates. In many parts of the United States, they are planted in early spring after the last frost. In warmer southern states, they may also be grown as fall or winter annuals.
Climate Considerations
Stock plants prefer temperatures between 55°F and 70°F. High summer heat can reduce bloom production. Gardeners in northern states like Minnesota or Michigan often enjoy a longer blooming season compared to hotter regions such as Texas or Arizona.
Soil and Water Needs
For healthy stock flower growth:
-
Use well-drained soil
-
Avoid waterlogged conditions
-
Water consistently but not excessively
-
Provide good air circulation
Adding organic compost can improve soil quality and encourage strong root development.

-
Antirrhinum (snapdragons)
White stock flower is particularly common in bridal bouquets because of its soft texture and romantic scent. Purple and blush tones are often used in spring centerpieces and seasonal décor.
