Growing Zone

Garnet Giant Mustard, 6 plants grows best in zones 6, 7, 8, and 9, but may do well outside that range as well.

Most leafy greens like the cooler temperatures, but they can generally grow year-round. You want to be aware of the extreme temperature ranges in your region. Refer to the guidelines below:

COLD CLIMATES

  • If you live in a location where the temperatures dip below freezing, hold off on growing until night temperatures are consistently in the 40's.
  • On the occasional dips into the 30's, you can cover your seedlings with a sheet overnight.

WARM CLIMATES:

  • If you regularly experience temperatures above 90 degrees for long periods of time, you may want to focus on herbs and heat-tolerant fruiting plants (tomatoes and peppers) during the heat intensive months.
  • Once temperatures are consistently in the 80's, you can start growing leafy greens.

To find out what extreme temperatures your location experiences, check out the USDA zone for your region.

About this plant

Organic Garnet Giant Mustard (Brassica juncea Garnet Giant) is a show-stopping culinary herb that brings high-contrast color and gourmet flair to the garden. It is easily recognized by its vibrant, oversized maroon leaves that sit atop brilliant lime-green stems, creating a stunning visual that looks just as good in a flower border as it does in a vegetable patch.

As a fast-growing member of the Brassica genus, Garnet Giant is prized for its "graze and braise" versatility. The entire plant is edible—the leaves, stems, and flowers all possess a sophisticated, sweet-yet-spicy flavor profile. Use the tender 20-day baby leaves to add a spicy kick and a pop of purple to fresh salads, or wait 45 days for mature leaves that are perfect for sautéing or stir-fries. Even the flowers are a culinary treat, offering a sweet and mild taste that makes them a beautiful garnish for any dish. Its superior hardiness ensures it stays productive and colorful throughout the cooler months of the growing season.

Why you’ll love it:

  • Stunning Ornamental Edible: Deep maroon foliage and lime-green stems provide instant "wow" factor in garden beds.
  • Fast & Productive: Harvest baby leaves in just 20 days or full-sized greens in 45 days.
  • Sweet & Spicy Flavor: Offers a more complex, gourmet heat compared to standard green mustard varieties.
  • Entirely Edible: Enjoy the tender leaves, crunchy stems, and sweet flowers in a variety of culinary applications.
  • Pollinator Friendly: If allowed to flower, the blooms are highly attractive to beneficial bees and butterflies.

This 6-pack healthy live plant thrives in full sun and prefers well-drained, fertile soil. It is particularly well-suited for cool-season gardening, as its color often intensifies with lower temperatures. Whether you are looking to spice up your "Cut and Come Again" salad garden or simply want a beautiful, edible accent for your patio containers, Garnet Giant Mustard is a versatile and high-yielding choice.

We take great care to ensure our seedlings are healthy and well-established before they’re shipped. Seedlings typically arrive within 1-4 days. For more information, see our shipping policy.
