Stock, or Matthiola incana, is a member of the Brassicaceae family of plants that includes cabbages. Originating in the wild in England, it is a favorite of cottage gardeners, prized for its dense clusters of fragrant blossoms.
Its Latin name is said to commemorate a 16th-century herbalist, Peter Matthioli (or perhaps Mattioli), personal physician to King Ferdinand I of Austria. Aa 1905 article titled “Memorial Plant Names,” in a Victorian-era British periodical called The Leisure Hour, refers to this likely origin.
A Multifaceted Plant
Also called gillyflower, tenweeks, or hoary, Brompton, or vintage stock, today’s colorful varieties are cultivars of the original M. incana wildflower.
This plant is known for its elongated racemes, or clusters, of single or double fragrant blossoms that rise on sturdy stems from lush grayish-green foliage.
There are other Matthiola varieties, including the night-scented M. longipetala. Visually, this variety pales in comparison, with its sparse, narrow petaled blossoms. However, it makes up for its shortcomings by emitting a heady scent in the evening.
M. incana is referred to as a half-hardy annual, biennial, and perennial.
How can this be?
This is a cool weather plant that blooms from early spring into summer. It needs temperatures below 60°F to set buds, otherwise you don’t get blossoms.
In cool regions, it grows as an annual that may withstand a frost or two, hence the term “half-hardy.” Sow seeds in early spring in these locations.
In warmer areas, M. incana is a perennial that may live for a few years, coming back with woodier stems each spring. Here, it blooms until summer heat becomes oppressive. It’s best to plant in the early fall.
The biennial characteristic refers to its tendency to bloom and set seed in the second year, in settings where it grows as a perennial.
Whatever its behavior, M. incana is the perfect choice for beds, borders, and container gardening. Sowed en masse, its soft blossoms blur like those in a watercolor painting, for a charming cottage feel.
There are numerous cultivars of the original M. incana, with heights ranging from an 8-inch dwarf variety, to taller Column and Imperial hybrids that exceed two feet.

Fragrant and Romantic
When it’s time to plan your next garden, be sure to include stock for cutting and bringing indoors.
I love to slip out early in the morning, when the dew still glistens, to collect an armful for a breakfast table centerpiece. Heliotrope and phlox are two of my other cottage garden favorites.
