Yellow Giant Hyssop Seeds – Tall, Fragrant Native with Medicinal Qualities (Agastache nepetoides) – Bee & Herbalist Favorite
Minimum: 100+ Seeds
A Towering Native Powerhouse for Pollinators and Herbalists Alike
If you’re looking for a towering, fragrant, and medicinal plant that brings both beauty and biodiversity to your garden, Yellow Giant Hyssop (Agastache nepetoides) is the answer. Native to the eastern and central U.S., this underappreciated prairie wildflower can grow up to 6 feet tall, producing pale yellow flower spikes that draw in a flurry of native bees, wasps, and butterflies. Whether you're a wild gardener, an herbal tea lover, or someone restoring native habitat, this graceful giant is a natural standout.
A Soothing Scent That Attracts Life
Yellow Giant Hyssop may not be as well-known as its purple cousins, but don’t let that fool you, this is one of the most beneficial and beautiful members of the mint family. It grows upright with a sturdy, square stem and long, lance-shaped leaves that emit a subtle anise or licorice fragrance when crushed. In late summer, it erupts into creamy yellow flower spikes that glow in the sunlight and vibrate with pollinator activity.

Ecological & Medicinal Wonder
This is one of those rare native perennials that’s both a pollinator magnet and traditional medicinal herb. Bees adore it, including native bumblebees and long-tongued specialists. In traditional herbalism, Agastache species have been used for teas and infusions said to help with digestion and soothe the nerves. While Agastache nepetoides is milder than its showier cousins like Anise Hyssop, it still offers aromatic and calming qualities.

A Living Beacon in Any Garden
I like to plant Yellow Giant Hyssop along fences or at the back of native beds, it adds vertical height without becoming aggressive. Despite its impressive size, it's well-mannered and blends beautifully with echinacea, milkweed, bee balm, or rudbeckia. It thrives in moist but well-draining soil and will even tolerate part shade, rare for a tall native bloomer.
