Very early, heavy bulbs with superb flavor—a major improvement in hybrid fennel.

This variety stood out in our trials with its lightly sweet flavor, uniformity and ability to hold in the field without bolting. Upright plants are easy to harvest. Early variety recommended for spring and summer harvest with good fall performance as well.

Cultural Info

Fennel (Foeniculum vulgare) is a hardy annual in the Umbelliferae family, which includes parsnip, carrot, dill, chervil, coriander, parsley, skirret and celery.

  • Bulbing-types produce large sweet bulbs.
  • Non-bulbing (leaf) fennel is grown as an herb or for seed and the attractive, feathery leaves.

Soil Nutrients and Requirements

Fennel needs deep, well drained, moderately fertile soil with a pH from 6.1-8.0. It has a very deep taproot.

Seeding Depth

1/4-1/2”

Plant Spacing 

Direct seed at 2” and thin to 6-8"

Row Spacing

18”

When to Sow

Direct seed fennel mid-spring through late summer, or start transplants 4-5 weeks before planting date. Plant outdoors after danger of hard frost has passed. Bolting can result from disturbing the roots.

Harvest

Harvest bulbs at 3-4” in diameter.

Storage

Fennel is delicate and will dry out quickly in storage. Store in cooler as close to freezing as possible. Quality will keep for 3-4 days.

Pest Info

  • Aphids, whitefly and lepidopterous larvae can be controlled by floating row cover in areas where they are a problem.

Disease Info

  • Fungal leaf blights caused by Alternaria dauci or Cercospora carotae can cause severe defoliation and greatly reduce yields. Generally, cercospora blight appears earlier in the season than alternaria blight. Both these fungi are seed-borne but can also be spread by crop residue from previous years.
  • White mold (Sclerotinia sclerotiorum) manifests as a cottony white mycelium around roots and lower plant parts, usually late in the season. Avoid planting in areas which are shady or have poor drainage, practice crop rotations with non-vegetable crops.
