Mustard Spinach Tendergreen HEIRLOOM Seeds

Brassica rapa

Item #0268

21-60 days. Often called Mustard Spinach or Spinach Mustard, it’s neither mustard nor a spinach. Japanese cooks call it Komatsuna. Whatever its name, this delicious, leafy green is very easy to grow and produces flat, smooth, dark, glossy green leaves that can be picked as baby greens or grown to full size. Hardy and productive plants are slow to bolt and tolerate cold, heat and dry conditions.

This packet sows eight 10-foot rows.

Days to Emerge:
5-10 days

Seed Depth:
1/4"

Seed Spacing:
A group of
3 seeds
every 8"

Row Spacing:
1'-1.5'

Thinning:
When 4" tall
thin to 1
every 8"


When to sow outside: RECOMMENDED. 4 to 6 weeks before average last frost, or in late summer (8 to 10 weeks before first frost). The advantage of late summer sowings is the best mustard flavor occurs after light fall frosts.

When to start inside: Not recommended

Harvesting: Start harvesting leaves when they are 2 inches tall, as needed, or let plant grow to maturity and remove entire plant.
