Triple-tested seed qualityRegular quality and germination checks support every packet.

We regularly test seed quality and germination as lots move through storage and packing. We stand behind the seed we send and want customers to contact us when a packet does not perform as reasonably expected.

1-year seed warrantyCoverage begins on the date of purchase.

When properly stored, planted, and cared for, we guarantee reasonable germination and true-to-type growth for one year from the date of purchase. Conditions outside our control—including extreme weather, pests, unsuitable storage, and gardener error—are excluded. Contact us when something is not right so we can review the situation and work toward a replacement, refund, or another fair resolution.

Non-GMO / BE seed policyWe do not buy or sell genetically engineered or bioengineered seed.

Every seed variety we sell is non-GMO.

USDA’s National Bioengineered Food Disclosure Standard defines bioengineered foods as containing detectable genetic material modified through in vitro recombinant DNA methods in ways not achievable through conventional breeding or found in nature.

  • Hybrid means parent lines were conventionally crossed; hybrid does not mean GMO.
  • Heirloom and open-pollinated describe how a variety is maintained and reproduced.
  • Organic certification is separate and is shown only when verified for the individual product.

Complete product description

Blue Hyssop Seeds

Description

A fragrant heirloom for pollinators and apothecaries alike. ‘Blue Hyssop’ produces upright spikes of deep violet-blue flowers above aromatic, gray-green foliage. Its leaves carry a minty, camphor-like scent long valued in teas, tonics, and traditional remedies.

Plants grow 18–24 inches tall, thriving in sunny, well-drained soil, and bloom from midsummer to frost. Loved by bees, butterflies, and hummingbirds, it’s as useful as it is beautiful.

Once revered in medieval herb gardens for purification and healing, hyssop remains a timeless herb of color, fragrance, and life.

Complete sowing and planting guidance

Planting Instructions:

Location Selection: Choose a location with full sun to partial shade for optimal growth.
Soil Preparation: Ensure the soil is well-drained and moderately fertile. Hyssop prefers slightly alkaline to neutral soil with a pH between 6.5 and 7.5.
Sowing Seeds:

Direct Sowing: Sow seeds directly outdoors in late spring after the danger of frost has passed. Plant seeds 1/4 inch deep and 12 inches apart in rows spaced 18-24 inches apart.
Indoor Starting: For an earlier start, sow seeds indoors 6-8 weeks before the last frost date. Use seed-starting trays filled with a seed-starting mix. Lightly press the seeds into the surface and keep the soil moist.
Germination: Seeds typically germinate within 14-21 days. Maintain consistent moisture levels in the soil during this period.
Transplanting: If starting indoors, transplant seedlings outdoors after the danger of frost has passed. Space seedlings 12-18 inches apart to allow for adequate air circulation and growth.

Care Instructions:

Watering: Water regularly to keep the soil evenly moist but not waterlogged. Hyssop requires consistent moisture for optimal growth.
Fertilizing: Apply compost or a balanced organic fertilizer if the soil is not rich enough.
Mulching: Apply a thin layer of mulch around the base of the plants to help retain moisture and suppress weeds.
Special Considerations:

Deadheading: Deadhead spent flowers regularly to encourage continuous blooming.
Pests and Diseases: Hyssop is generally pest and disease-resistant but can be affected by aphids and spider mites. Use organic methods like neem oil or insecticidal soap if necessary.
