The Story
Plant Bio
Valerianella locusta is a low-growing, compact annual herb that forms a tight basal rosette of succulent, spoon-shaped leaves before bolting in spring. The plant produces dichotomously forked flowering stems topped with dense, small clusters of minute, bluish-white flowers.
This exceptionally cold-hardy salad green tolerates hard freezes down to 5°F, making it a reliable winter-harvest crop. The soft-textured, mild-flavored foliage offers an excellent cool-season alternative to traditional lettuces.

Planting
How to Grow
- Sow seeds directly into fertile, well-draining loamy or sandy soil in early spring or late summer.
- Space seeds or thin seedlings to 4 to 6 inches apart to allow proper rosette development.
- Maintain consistent soil moisture, watering regularly to prevent the succulent leaves from becoming tough or bitter.
- Harvest outer leaves individually or cut the entire rosette at the base before the plant begins to bolt.
Pro Tip
Sow seeds only when soil temperatures are below 68°F (20°C); warmer soils trigger thermodormancy, completely preventing germination.

Care Guide
Do
- Sow in cool weather when soil temperatures are between 50°F and 65°F.
- Provide partial shade during warm spring spells to delay bolting.
- Incorporate a light application of compost or organic fertilizer prior to planting.
Don't
- Do not sow seeds in midsummer, as high temperatures prevent germination.
- Avoid overhead watering to minimize the risk of downy and powdery mildew.
- Do not allow the soil to dry out completely, which causes immediate drought stress and premature bolting.
