Stock flowers (Matthiola incana) captivate gardeners and florists with their spiky, clustered blooms and signature sweet clove fragrance. These Mediterranean natives grow on sturdy stems reaching 18-24 inches tall, producing densely packed flower heads in single or double forms. Beyond traditional garden varieties, modern cultivars offer ruffled petals and bicolor combinations.
The flowering season spans from early spring through early summer, with peak blooms appearing when temperatures remain mild. Professional growers often utilize succession planting techniques to ensure continuous blooming throughout the season.
The color palette ranges from pristine whites and soft creams to vivid pinks, purples, and rich burgundies. Some varieties showcase unique slate blue or antique bronze tones. Single-flowered types typically display more intense colors, while doubles offer subtle pastel variations.
For optimal growth, plant stocks in well-draining soil with full sun exposure. Maintain consistent moisture without waterlogging and provide adequate air circulation to prevent fungal issues. Remove spent blooms promptly to encourage continued flowering. Cut flowers last 7-10 days when stems are trimmed at a 45-degree angle and placed in clean water containing floral preservative.

Common Name & Botanical Name
The stock flower, Matthiola incana, belongs to the Brassicaceae family and carries several regional names including Gilly flower, Ten-week stock, and Hoary stock.
Its genus name honors Pietro Andrea Mattioli, a 16th-century Italian botanist, while ‘incana’ refers to the plant’s characteristic hoary or gray-white appearance.
Originally native to southern Europe and the eastern Mediterranean, these plants have been cultivated since the Victorian era for their sweet-scented flowers and ornamental value.
The species includes both annual and biennial varieties, with colors ranging from white and cream to pink, purple, and red.
Modern cultivars have been developed to produce double-flowered forms, which are particularly prized in the cut flower industry for their extended vase life and intense fragrance.
Flower Type & Family
Stock flowers (Matthiola incana) stand as distinctive members of the Brassicaceae family, exhibiting their botanical connection to cruciferous vegetables.
These ornamental plants produce densely packed flower spikes, featuring either simple four-petaled blooms or intricate double-flowered varieties with multiple layers of petals.
The floral palette spans across cool and warm tones, encompassing pure white, rose pink, deep crimson, lavender, purple, and buttery yellow hues. The plants develop strong, erect stems supporting the flower clusters, reaching maturity heights between 30 to 60 centimeters.
As cool-season performers, stocks demonstrate remarkable resilience in spring and autumn conditions, offering gardeners extended blooming periods and rich fragrances reminiscent of clove and spice notes.
These adaptable plants suit both border gardens and cutting arrangements, with modern cultivars developed specifically for commercial floristry and home cultivation.
Their genetic heritage as Mediterranean natives contributes to their drought tolerance once established, though they maintain optimal performance in well-draining, fertile soils.
Visual Description & Colour Varieties
Stock flowers (Matthiola incana) showcase an extensive palette of vibrant colors, including classic pure white, blush pink, deep magenta, royal purple, burgundy, and buttery yellow varieties. Many cultivars feature bicolored petals or gradient effects, where the flower’s center displays a different shade than its outer edges.
Beyond their ornamental value, the diverse color range plays a crucial ecological role. White and pale pink varieties emit stronger fragrances during evening hours, attracting nocturnal moths. Meanwhile, the deeper purple and magenta cultivars draw daytime pollinators like bees and butterflies. The yellow varieties particularly appeal to hover flies and other beneficial insects.
Each color variant demonstrates unique growth characteristics. White cultivars typically exhibit stronger stems, while purple varieties often develop more lateral branches. The pink and magenta types generally produce more abundant blooms per stem.
Selecting specific colors requires consideration of local climate conditions, as certain hues may fade more quickly under intense sunlight or maintain their vibrancy better in partial shade.
Blooming Season & Florist Availability
Stock flowers display distinct bloom cycles that peak during late spring to early summer months, specifically from late April through mid-June.
Professional growers carefully schedule their cultivation to maximize availability during these prime flowering periods. Garden centers and florist shops typically stock multiple varieties of these fragrant blooms, from classic white to deep purple cultivars.
Experienced growers utilize controlled environments and strategic planting schedules to extend the natural flowering window, enabling consistent market supply throughout the main growing season.
Regional climate variations can influence exact availability, with warmer zones often seeing earlier blooms compared to cooler areas.
Fragrance
Stock flowers (Matthiola incana) emit a distinctive fragrance that combines spicy clove notes with sweet floral undertones. The aromatic compounds reach peak intensity in the evening hours when temperatures drop, making these blooms particularly valued for twilight gardens and moon gardens.
Environmental elements significantly influence the fragrance production:
| Fragrance Factors | Impact on Stocks |
