Pac Choi and Choi Sum

Ching Chiang

Brassica oleraceae var. chinensis
Also known as Shanghai Pac Choi, this is a beautiful little vase-shaped plant. This early baby pac choi is mild and tender with medium-green leaves on pale-green, spoon-shaped stalks (petioles). Bred to be tolerant to heat, rain, cold, and dampness, Ching Chiang is a great variety for early spring planting under cover and for late summer plantings in mild-winter areas. Harvest when 15cm (6") tall.
Matures in 45 days. (open pollinated seeds)

Jade Spring

Brassica rapa var. chinensis

A short season, fast-growing hybrid variety of Yu Tsai Sum (or Choy Sum) that produces raw stems with the texture of lightly steamed asparagus, with a sweet, mild taste. Stems will be 5mm - 1cm thick if grown and watered well. Early spring plantings may bolt. The incredible flavour will have you eating it raw, straight out of the garden, before it can be cut for stir-fries, salads, or soups.

Matures in 35-45 days. (hybrid seeds)

Joi Choi

Brassica oleraceae var. chinensis
Dark-green leaves are supported by glowing, thick, sweet, white stalks that are mild and juicy with hardly a hint of mustard. Plant grows to 45cm (18"). Space 60cm (12") and harvest promptly. Cover with cloche if planting in very early spring, as plants will bolt if seedlings are exposed to cold temperatures. In summer, plant short rows and harvest promptly before it bolts. The mature plant is somewhat cold-hardy, so plant again in late summer.
Matures in 50 days. (hybrid seeds)

Mei Qing Choi

Brassica rapa chinensis
Pronounced "may-ching-choy," this dwarf Shanghai pac choi is tender, sweet, and crunchy. Short, compact plants are slow to bolt, but also cold-tolerant, for surprisingly long harvest periods. Very uniform, with pale green petioles, and lovely, rounded, flat leaves. Perfect for early spring to late fall, and will overwinter with some protection.
Matures in 40 days. (hybrid seeds)

Taiwan Pac Choi

Brassica rapa chinensis
Mid green leaves are supported by thick, sweet, white stalks that are mild and juicy. In summer, plant short rows and harvest promptly before it bolts. Plant again at the end of summer for fall and early winter harvests. Great raw or cooked in stir-fries and soups.

Matures in 35-45 days. (open pollinated seeds)

Toy Choy

Brassica oleraceae var. chinensis
This miniature pac choi can be picked at the "single serving" size. Dark green leaves and glistening white stems mark this as a standout in a display. You can use these delicacies gently braised and served whole to appreciate the mild flavour and graceful appearance. The add flavour and crunch to stir-fries.
Matures in 30-50 days. (hybrid seeds)

White Stemmed Pac Choi

Brassica oleraceae var. chinensis
Thick, elongated, green leaves grow on long, thick, pale white stalks amd have a mild, sweet flavour welcome in salads and excellent in stir-fries. Thin to 30cm (1'). This pac choi may be grown from early spring to late fall. This variety forms nice, compact urn-shaped heads with broad leaves.
Matures in 50 days. (open pollinated seeds)

Yu Tsai Sum

Brassica rapa var. chinensis
Yu Tsai Sum is a type of choi sum. This summer crop is also known as Yu Choy. Grown for tender flower bud stalks (yellow flowers) and glossy, bright green leaves, it is mild and sweet when cooked briefly. Stems will be 0.5-1cm (1/4-1/2") thick if grown and watered well. This variety was tops in our trials for both taste and texture. For large plants, sow in rows 30-45cm (12-18") apart. Cut the flower bud stalk with a few leaves - new shoots will grow from a leaf axil. Plant in early summer, up to 6 weeks before frost. Early spring plantings may bolt. Cole crop.
Matures in 40-60 days. (open pollinated seeds)
