From Jakarta to Your Backyard: 5 Indonesian Leafy Greens Worth Growing Right Now

Here's a little secret most American home cooks don't know: a huge chunk of Indonesian cuisine depends on leafy greens so fresh they're practically still breathing. In Indonesia, these vegetables go from garden to wok in minutes. In the US, the same greens often travel thousands of miles, sitting in cold storage until they're a shadow of their former selves.

At Hijau Daun Kitchen — hijau daun literally means "green leaf" in Indonesian — we're all about bridging that gap. And the best way to do it? Grow these beauties yourself. Here are five Indonesian leafy greens that are more backyard-friendly than you'd expect, along with honest advice on how to actually pull it off in the US.

1. Kangkung (Water Spinach): The One That Grows Almost Too Well

Kangkung is arguably the most beloved leafy green in all of Indonesian cooking. You'll find it in cah kangkung (stir-fried with garlic and shrimp paste), floating in soups, and wilted into rice dishes. The hollow stems and tender leaves cook in under three minutes and have this mild, slightly grassy sweetness that's completely lost by the time grocery store versions reach your plate.

Growing it in the US: Kangkung loves heat and moisture, which makes it a dream in the Deep South, Gulf Coast states, and Hawaii. If you're in the mid-Atlantic or Pacific Northwest, you can still grow it through summer — just give it a sunny spot and consistent water. Note that water spinach is classified as a noxious weed in Florida and a few other states, so check your local regulations before planting. For most of the country, though, you're fine.

Where to find seeds: Asian seed suppliers like Kitazawa Seed Co. and Evergreen Seeds carry kangkung reliably. Look for the "land type" variety if you don't have a pond or water feature — it grows happily in regular garden soil that's kept consistently moist.

The flavor difference: Homegrown kangkung has a clean, almost buttery quality when stir-fried. Store-bought versions tend to be stringy, slightly bitter, and limp before they even hit the pan. Not the same vegetable, honestly.

2. Bayam (Indonesian Amaranth): Not Your Grandmother's Spinach

Bayam looks a bit like spinach at first glance, but don't be fooled. Indonesian amaranth leaves are slightly thicker, hold up better to heat, and have a mild earthiness that makes them ideal for the classic sayur bayam soup — a clear, lightly sweet broth with corn and tofu that's one of the most comforting things you'll ever eat.

Growing it in the US: Amaranth is one of the most adaptable plants on this list. It handles heat, tolerates drought once established, and grows fast — you can start harvesting leaves in about four weeks. It's a solid choice for gardeners in the Southwest, Southeast, and anywhere with a long warm season. In cooler zones like the Upper Midwest or New England, start seeds indoors six weeks before your last frost date.

Seed sourcing: Look for Amaranthus tricolor varieties specifically marketed for leafy use, not grain production. Ethnic seed suppliers and some Asian grocery store seed racks carry the right type.

The flavor difference: Fresh bayam has a delicate sweetness that practically disappears after a few days off the plant. The store-bought stuff, if you can even find it, often tastes vaguely metallic. Homegrown? It's genuinely pleasant eaten raw in a salad.

3. Daun Singkong (Cassava Leaves): The Underdog Green

Cassava leaves are a big deal in Indonesian cooking — especially in dishes like gulai daun singkong, a rich coconut milk curry from Sumatra. In the US, fresh cassava leaves are nearly impossible to find commercially, which is exactly why growing your own is such a game-changer.

Growing it in the US: Cassava is a tropical plant, so it's best suited for USDA hardiness zones 8 and warmer (think Southern California, Texas, the Gulf Coast, and Florida). In cooler zones, you can grow it in large containers and bring it indoors before the first frost. It needs full sun and well-drained soil.

Important note: Cassava leaves must be cooked — boiled for at least 15–20 minutes — before eating to neutralize naturally occurring compounds. This is standard practice in Indonesian cooking, so it's nothing to be intimidated by.

The flavor difference: Properly cooked fresh cassava leaves have a rich, slightly bitter depth that pairs beautifully with coconut milk. Frozen versions (the only real alternative in the US) are functional but lack the brightness fresh leaves bring to a dish.

4. Pechay (Bok Choy's Indonesian Cousin): The Beginner-Friendly Pick

Pechay is a leafy green widely used across Indonesian and Filipino cooking, closely related to bok choy but with broader, darker leaves and a more pronounced vegetal flavor. It shows up in simple sautéed side dishes, clear broths, and noodle soups. It's the kind of vegetable that makes a plain bowl of rice feel like a complete meal.

Growing it in the US: This is your starter green if you're new to growing Asian vegetables. Pechay is cool-season-friendly, meaning you can grow it in spring and fall almost anywhere in the continental US. It bolts (goes to seed) in heat, so time your planting for when temperatures are consistently below 75°F. In the South and Southwest, fall is your best window.

Where to find seeds: Filipino and Indonesian grocery stores sometimes sell seed packets near the checkout. Online, look for "Philippine pechay" to get the right variety rather than standard bok choy.

The flavor difference: Freshly harvested pechay has a peppery, almost mustard-like quality that softens beautifully when cooked. Grocery store bok choy is a decent substitute, but it's genuinely milder — and milder isn't always better.

5. Kemangi (Indonesian Lemon Basil): The Aromatic Wildcard

Kemangi isn't a leafy green in the traditional sense, but it functions like one in Indonesian cooking — used in generous handfuls rather than as a garnish. It's scattered over pepes ikan (fish steamed in banana leaves), tossed into fresh salads called lalapan, and stirred into sambals. The fragrance is somewhere between sweet basil and lemongrass, and it's absolutely intoxicating.

Growing it in the US: Lemon basil grows just like sweet basil — which means it's happy in pots on a sunny windowsill, a balcony, or a garden bed from late spring through early fall. It's one of the most forgiving plants on this list.

Seed sourcing: Look specifically for Ocimum × citriodorum or "lemon basil" seeds. The Indonesian variety (sometimes labeled kemangi at Asian seed suppliers) has a slightly more intense citrus note than standard lemon basil, but either works beautifully.

The flavor difference: Fresh kemangi wilts and loses its perfume within hours of being cut. There is no dried version worth mentioning. Growing it yourself is essentially the only way to experience this herb at its best in the US — and once you do, you'll wonder why you waited so long.

A Few Practical Tips Before You Start

Start with one or two varieties rather than all five at once. Kangkung and kemangi are probably the easiest entry points for most US gardeners. Join online communities like r/AsianGardening or local Facebook groups focused on ethnic vegetable growing — these communities are incredibly generous with seed swaps and growing advice specific to your climate zone.

And honestly? The moment you taste a dish made with greens you grew yourself — still warm from the sun, cooked within an hour of picking — something clicks. You understand why Indonesian home cooking tastes the way it does. The freshness isn't incidental. It's the whole point.
