🥬 Purple Lady Bok Choy: Growing Guide
What it looks like
Why this variety
Purple Lady is bok choy dressed for a party: deep purple, almost black leaves on tender green stems, in a squat, compact rosette that looks ornamental and cooks beautifully. The color holds well in the pan compared with many purple greens, and the flavor is mild and sweet — this is a purple vegetable that tastes as good as it looks, which is not always a given.
Purple in leaves means anthocyanins, the sunscreen pigments that also act as antioxidants in the diet. In bok choy, the purple is mostly in the leaves while the stems stay green, which gives you a two-tone vegetable that is also a nutrition lesson: the darker the leaf, the more anthocyanin, and Purple Lady’s near-black leaves are among the darkest in the bok choy family.
Florida translation: Purple Lady is a fall-through-spring bok choy here, and its color deepens in cool, sunny weather — fall-grown plants are the most dramatic. Grow it like any baby bok choy: rich soil, even moisture, afternoon shade in warm spells, and harvest before heat pushes it to flower. A row of Purple Lady next to green bok choy is the easiest ornamental-edible border a cool-season bed can have.
How to grow
Sow Purple Lady Bok Choy directly or transplant, spacing as listed in the hero block. Full-size types need room; baby types can tuck in closer. Bok choy is a cool-season Asian green: in Florida, sow from fall through early spring, give afternoon shade if a warm spell hits, and succession-sow every two weeks for a steady supply rather than one giant glut.
Work worm castings into the bed at planting. Bok choy grows fast and shallow, so a fine, firm seedbed and steady moisture from day one matter more than fancy feeding — a checked seedling bolts, and a bolted bok choy is compost.
Water & feeding
Bok choy grows fast and drinks steadily. Keep the soil evenly moist, mulch to hold that moisture, and feed with compost or a balanced fertilizer at planting and again halfway to harvest. Dry soil plus heat is the recipe for bolting, so water before the leaves wilt, not after.
Common problems
Flea beetles love brassica seedlings, and cabbage worms love the leaves. Row cover over young plants solves most of it, and hand-picking handles the rest. Bolting is the other enemy: plant for cool weather, keep soil moist, and harvest promptly when heads size up — a warm week can push a mature head to flower in days.
Harvest
Cut Purple Lady Bok Choy whole at the base when heads are full and firm, before a flower stalk appears — or harvest outer leaves as needed and let the center keep growing. Baby heads, cut young, are tender enough for salads; full heads are made for stir-fries, soups, and braising, stalks first into the pan, leaves a minute later.
Nerdy fact: Purple Lady’s purple leaves cook toward green because anthocyanins are sensitive to heat and pH — a quick stir-fry keeps more color than a long braise, which is a good excuse to cook bok choy fast, the way it likes to be cooked anyway.

As an open-pollinated bok choy it comes true from seed: sow Purple Lady directly or transplant, spacing as listed in the hero block.
