SalsifyTragopogon porrifolius
Salsify is a nearly forgotten jewel of the monastery garden. Its delicate flavor, reminiscent of oysters, makes it a true delicacy among winter vegetables. This biennial plant forms a sturdy taproot in its first year, followed by beautiful purple flower heads in the second year that open only during morning sunshine.

Preventing premature bolting Remove flower stalks immediately so energy is directed to the root.
Remove
- Flower stalks in the first year (if present)
- Yellowed or diseased leaves
- Seed heads in the second year to prevent self-seeding
Preserve
- Healthy leaf rosette in the first year
- Heart leaves for continuous growth
Avoid
- Radical cutting of healthy leaves
- Damaging the root crown
Tools and hygiene
Use clean knives to prevent rot at the root crown.
