Availability: In Stock
Big, bold, maroon leaves with lime veins are as delicious as they are ornamental in the garden or a container. Excellent pickled, wilted, or raw in salads, 'Red Giant's' mustard flavor intensifies in older leaves and hot weather, providing hints of horseradish. This traditional Asian green is faster growing and spicier than traditional southern mustards. Cold tolerant and bolt resistant.
$1.99 2 grams (~670 seeds)

Botanical Name: Brassica juncea

Days to Maturity: 40 days

Family: Brassicaceae

Native: Widespread, probably Asia

Hardiness: Frost-tolerant annual

Plant Dimensions: 12"–24" tall

Variety Information: Slightly savoyed, purplish-red, thick and tender leaves, in a loose head. Spicy, rich horseradish flavor intensifies with heat and as leaves get larger. 'Red Giant' can be used when very young and small, or more matured. If left to reseed, the volunteers revert to its strong-tasting, wild predecessor. It is particularly tolerant to cold and bolting, and has wide soil adaptability.

Attributes: Good for Containers, Heat Tolerant

When to Sow Outside: RECOMMENDED. 4 to 6 weeks before your average last frost date, when soil temperature is at least 40°F, ideally 60°–75°F. Successive Sowings: Every 3 weeks until 10 to 12 weeks before your average first fall frost date for continuous harvest. Mild Climates: Sow in late fall through winter for cool–season harvest.

When to Start Inside: Not recommended; transplant stress can cause plants to bolt (prematurely flower).

Days to Emerge: 5–10 days

Seed Depth: ¼"

Seed Spacing: A group of 3 seeds every 4" – 6"

Row Spacing: 12"–18"

Thinning: When 3" tall, thin to 1 every 4" – 6"

Harvesting: Harvest in the morning if possible. You may start harvesting leaves when they are 2" tall, as needed; remove no more than 1/3 of the plant if regrowth is desired, or let plant grow to maturity and harvest entire plant. Late summer crops will last until the first hard freeze.

Red Giant Mustard is super spicy!

5 out of 5 stars Jul 7, 2020
I love this mustard seed. The plants are huge and I eat it while I am gardening and it opens up my sinuses and clears my head. This is the best mustard plant I have ever grown and it does great until the heat hits. I can't wait to plant it again in the fall.

Deliciously spicy mustard

5 out of 5 stars Apr 7, 2021
My favorite mustard. Spicy, with no bitterness. When it's young, it even has a bit of a sweetness. When spicy, it has a nice, wasabi like heat. The plant is beautiful to look, with huge billowing reddish/purple leaves and green stems. It's a great vegetable for edible landscaping. Super easy to germinate. One of my favorite plants.

I completely agree with the other reviews. This is a wonderfully spicy mustard green. Adds lots of flavor to salads. It has been very heat tolerant here in Northern Colorado as well.

A Wonderful Mustard

5 out of 5 stars Apr 22, 2022
One of the bonafide hits of this year's winter garden. Good germination rates, decently quick initial growth and, once mature, excellent re-growth. We'd pick these clean for stews, sides, etc., and they'd be ready for another harvest two weeks later. Lovely color to add to the garden as well. Highly recommended!
