Stock 'Rose Pink' StoX

Rose Pink StoX (Matthiola incana)

Also known as Stock or Gillyflower

Rose Pink carries the gentle charm of faded petals pressed between the pages of an old book — a soft, medium-light rose hue with a muted elegance that sets it apart from brighter, bolder pinks. Its scent is sweet and nostalgic, a reminder of cottage gardens and sun-warmed afternoons.

Each plant sends up a single, upright stem, adorned with florets in either single or double form. When doubles appear, their layered petals catch the light like silk, perfect for creating arrangements steeped in romance. Rose Pink blends effortlessly with pale apricots, ivory blooms, dusty blues, and cool silver foliage, adding balance and warmth to bouquets.

Plant in full sun and well-drained soil. This variety produces only one flowering stem per plant and should not be pinched, allowing it to rise in quiet, unbroken beauty.

Transplant (recommended): Stock is a cool-weather crop, so starting transplants indoors is the best way to get ahead of the heat. Sow seeds 5–6 weeks before you plan to move them to a field or a protected structure. For a continuous harvest of flowers, make successive plantings every two weeks. The optimal times for growing are for spring and fall blooms.

Direct Seeding (alternative): Sow seeds directly outdoors after all danger of frost has passed. This method may result in a later bloom time compared to starting indoors.

Selecting for Double Flowers

While a difficult and time-consuming process, you can select for double-flowering plants by observing visual differences in the seedlings. After the seedlings have emerged and are in the cotyledon stage, expose them to chilling temperatures of 4-7°C for 3-4 days.

After chilling, you can identify the types of flowers the plants will produce:

• Select lighter green seedlings with an oval-shaped cotyledon; these will produce the desired double flowers.

• Seedlings with a darker green color and rounder cotyledons will produce single flowers.

Pinching: Do not pinch stock plants. Pinching can negatively affect the development of their single, central flower spike, which is the primary source of their classic bloom.

Pest Prevention: As a member of the brassica family, stock is a favorite food for flea beetles. To protect young plants from damage, cover them with a floating row cover immediately after transplanting them into the garden.

Soil Preference and Watering: Stock thrives in full sun and requires well-drained, fertile soil. Keep the soil consistently moist but never soggy. Once plants are established, water deeply but infrequently.

Fertilizing: To encourage strong growth and beautiful blooms, fertilize with a balanced liquid fertilizer every 2–4 weeks. A layer of compost applied at planting time can also provide a good nutrient base.
