Tall White Stem F1 Bok Choy Seeds

Tall White Stem F1 Bok Choy Seeds — Classic Full-Size Pak Choi Hybrid | Thick White Stalks, Bolt-Resistant, Spring & Fall

In Chinese kitchens, it has been on the table for over 1,500 years. Crisp white stalks that shatter when you bite them. Dark, glossy leaves that wilt perfectly in a screaming-hot wok in under two minutes. A flavor so clean and mild it carries any sauce, any seasoning, any cuisine you bring to it. Tall White Stem Pak Choi F1 (Brassica rapa subsp. chinensis) is the full-size, market-quality bok choy — substantial, beautiful, and one of the fastest cool-season crops you can grow.

Sow it in spring. Sow it again in the fall. Keep the wok ready.

Why Tall White Stem F1?

• Classic full-size form: Tall, upright heads at 30–45 cm (12–18 in) with thick, pure white stalks and dark glossy leaves — the market-quality bok choy form that performs as well in the home garden as it does commercially
• Improved bolt resistance: F1 hybrid breeding delivers significantly better bolt tolerance than open-pollinated types — critical for extending the spring harvest window before summer heat arrives
• Fast maturity: 50–60 days from transplant — one of the quickest cool-season crops from seed to table
• Dual harvest method: Harvest whole heads for maximum impact, or harvest outer leaves continuously for a cut-and-come-again approach that extends production across weeks
• Exceptional uniformity: F1 hybrid consistency means every head matures at the same size and quality — ideal for succession plantings and planned harvests.
• Nutrient-dense: Outstanding source of vitamins C, K, and A; significant plant-based calcium; glucosinolates associated with cancer-protective activity in research

Two Seasons, One Variety

Pak choi is a true cool-season crop — it thrives in the shoulder seasons when most of the garden is quiet. Plant in early spring as soon as the soil can be worked for a late spring harvest. Plant again in late summer for a fall harvest that often produces the finest quality heads of the year — cool nights concentrate sweetness and deepen flavor. Succession sow every 2–3 weeks within each season for a continuous supply.

In the Kitchen

• Stir-fry: The definitive preparation — split heads lengthwise, add stalks to a screaming-hot wok first, leaves 60 seconds later; finish with garlic, ginger, oyster sauce or soy and sesame oil
• Braised: Whole heads braised in chicken or vegetable broth with ginger, garlic, and a splash of Shaoxing wine — silky, deeply savory
• Steamed: Halved and steamed until just tender; finish with hot oil poured over garlic and soy sauce for a classic Cantonese preparation
• Grilled: Halved, brushed with miso butter or sesame oil, grilled over high heat until charred at the edges and tender at the core
• Soup: Essential in ramen, hot and sour soup, and miso soup; add whole leaves in the final minute of cooking
• Raw: Young inner leaves in salads; shredded white stalks in Asian-style slaws with sesame dressing

Growing Notes

• Type: F1 hybrid cool-season annual — seeds will not breed true
• Days to maturity: 50–60 days from transplant
• Germination: 4–7 days at 60–70°F — fast and reliable
• Spring sowing: Start 4–6 weeks before last frost, or direct sow as soon as soil can be worked; transplant out 2–3 weeks before last frost
• Fall sowing: Direct sow 6–8 weeks before the first expected fall frost; fall crops often produce the finest quality
• Succession sowing: Every 2–3 weeks within each season for continuous harvest
• Light: Full sun to part shade; part shade extends the season in warmer climates
• Spacing: 20–30 cm (8–12 in) for full heads; 10–15 cm (4–6 in) for cut-and-come-again leaf harvest
• Watering: Consistent moisture is critical — drought stress triggers bolting; mulch to retain soil moisture
• Pest management: Flea beetles and cabbage worms are the primary pests — row cover from the day of transplant is strongly recommended, especially for spring plantings
