Salsify
Tragopogon porrifoliusAn old-fashioned root grown for its faintly oyster-like flavor, taking most of a growing season to swell into a long, tapering, carrot-shaped root. Deep, stone-free soil matters far more than fussing over the leafy top growth. The one rule: never transplant it — any check to the taproot makes the root fork.

When to sow salsify
- Sow from about 3 weeks before your last expected frost until around your last expected frost.
Direct sow only — salsify forks badly if its taproot is disturbed.Dig deep and remove stones first; roots need loose soil to grow straight.Sow thinly and be patient — germination is slow and can be uneven.
Water evenly through summer; irregular moisture splits the roots.Weed by hand while young — the grassy seedlings are easy to mistake for weeds.Mulch to keep the soil consistently cool and moist around the root.
Lift roots in autumn once they reach finger to thumb thickness.Loosen deeply with a fork first; the long taproot snaps easily if pulled.Leave some in the ground over winter — frost sweetens the flavor further.
Companion plants
Other root crops share salsify’s taste for deep, loose soil and rarely compete for the same nutrients.
Watch out for
Slugs — Target slow-germinating seedlings before they can establish. Clear nearby debris and check under covers at dusk.White rust — A fungal disease that blotches leaves in humid conditions. Space plants well and avoid overhead watering.
