How to Grow Salad Burnet USA

Soil & Growing Conditions

Water: intolerant of drought despite its wild-grassland origins

Growth Stages

Stage	BBCH	Notes
Sowing and germination	0	Sow outdoors in mid to late spring, or indoors in early spring 4-6 weeks before the last frost, covered with about 3mm of soil and kept moist; germinates in 7-14 days (Harvest to Table).
Rosette establishment	1	Space plants about 30-38cm apart in full sun on well-drained soil of alkaline or neutral pH; leaves form a low rosette of paired toothed leaflets (RHS, Harvest to Table).
Leaf harvest	4	Plants reach harvestable size about 70 days from sowing; pick young leaves, which have the best cucumber flavour, and keep picking to encourage tender new growth (Harvest to Table).
Flowering and seed	6	Flowering stems rise to 0.5-1m carrying knobbly crimson flower clusters from early summer through autumn, followed by burred fruit; plants mature over 1-2 years and can be increased by division (RHS).

Harvest & Storage

When to pick: Cut the plant back regularly to encourage new growth -- the youngest leaves have the best flavour. Remove flowers after blooming to discourage self-seeding.

Salad Burnet, the Cucumber-Scented Chalk Grassland Herb

Dangling stamens

Long stamens hang from the flower head, which is wind-pollinated rather than insect-pollinated.

Burred fruit

Flowers give way to distinctive burred fruit, and plants are easily raised from this seed.

What the research guides add

Two reputable sources disagree on one point, drought, and both agree on the rest.

• Salad burnet prefers full sun in a well-drained but consistently moist spot, and likes low-nutrient soil (Herb Society). (Herb Society of America)
• NC State calls it intolerant of drought and shade, though it tolerates alkaline soils and browsing by deer. (NC State Extension)
• The delicate fern-like leaves have a cucumber flavour; for best flavour use young leaves fresh rather than dried. (Herb Society of America)
• It does not grow well in a pot, as it needs at least 15 inches of depth for its extensive root system. (Herb Society of America)
• It spreads by self-seeding; removing the flowers once they have bloomed discourages this. (NC State Extension)
