Red Tatsoi Mustard is a cool-season Asian green that transforms as it matures, revealing deep reddish-purple foliage that makes it as stunning on the plate as it is in the garden. This non-GMO Brassica Rapa cultivar grows to 18-24 inches tall and reaches full harvest size in just 40-49 days, making it one of the quickest greens you can grow. Hardy from zones 2 to 10, it thrives in full sun and adapts to both microgreen production and full-sized leaf harvesting, giving you flexibility in how you use it.

Red Tatsoi transitions from green cotyledons to deep reddish-purple by day 4 when grown as a microgreen, creating a visually arresting crop ready in just 7-10 days. The speed is remarkable: whether you're harvesting tender microgreens or waiting for full-sized leaves, this variety delivers results fast. Its dual nature as both a quick microgreen crop and a substantial cool-season green makes it unusually adaptable for small and large gardens alike.
Red Tatsoi works beautifully as a microgreen, where its color-shifting leaves add visual interest and a delicate texture to salads, grain bowls, and plated dishes. At full size, the tender leaves function as a cool-season Asian green for sautéing, braising, or adding raw to salads and wraps.
Start Red Tatsoi indoors in warm, well-draining soil. Seeds germinate quickly and can be transplanted outdoors once established.
Harden off seedlings gradually before moving them to the garden. Space transplants 6 inches apart in full sun. The soil should be well-draining.
For microgreens, harvest when the cotyledons open and change to reddish-purple, typically around day 7-10 after sowing. At full size, begin harvesting outer leaves once the plant reaches usable size around 40-49 days, or cut the entire plant at the base. The color deepening to reddish-purple is your visual cue that the microgreens are at peak harvest readiness.
