Malabar Spinach

Malabar spinach is not spinach. It is a tropical vine from Asia that happens to produce leaves with a flavor resembling spinach, and gardeners plant it for one reason: it thrives in the heat that causes real spinach to bolt and die. Where a June heatwave turns a bed of true spinach into bitter, flowering stalks, Malabar spinach keeps producing thick, succulent leaves straight through August. The trade-off is texture — the leaves have a slight mucilaginous quality when raw, similar to okra, which surprises people who expect crispness.

The plant is a vigorous climber. Left unsupported, it will sprawl across the ground and tangle into adjacent crops; given a trellis, it can easily reach six to eight feet by midsummer. A sturdy vertical support — cattle panel, bamboo teepee, fence — is not optional. The stems are fleshy and heavy when mature, and a flimsy trellis tends to collapse under the weight by late July.

Start seeds indoors about six weeks before your last frost, but wait to transplant until the soil is genuinely warm — at least two weeks after the frost date, when night temperatures stay above fifty-five. A Malabar spinach transplant put out into cool spring soil will sit and sulk for weeks, turning its leaves pale and refusing to grow. The same plant moved into seventy-degree soil will be climbing within days.

Harvest by pinching off the top few inches of stem, which encourages branching and keeps the plant producing new tender growth. The youngest leaves and stem tips are the least mucilaginous and the most palatable; older leaves can be thick and tough. Cooked, the texture becomes less noticeable — steamed, stir-fried, or added to soup, the leaves behave much like spinach or chard.

The plant tends to produce small white or pink flowers in late summer, followed by dark purple berries. The berries are edible but bland; their real value is as seed for next year. Collecting a handful of ripe berries in September and drying them on a plate gives you more seed than you'll ever need.

In warm climates — zone 8 and above — Malabar spinach can become weedy if the berries drop and sprout. Deadheading the flowers before they set seed tends to prevent volunteer plants the following year, though some gardeners welcome the self-sowing habit as free starts.
