Edible Greens in Hawaii





I’ve updated this article to include some new greens that particularly easy to grow. Check it out.

If you don’t have time to garden–planting seeds, fertilizing, mulching, pulling weeds and watering, this story is for you.

There are a number of edible greens in Hawaii that grow easily with little intervention on your part. You can have fresh greens any time you want right in your own yard.

Here are a few of my favorites:

Brazilian Spinach or Sissoo (alternanthera sissoo)

Brazilian spinach or sissoo

One of the easiest to grow, as well as a living mulch or edible ground cover is Brazilian spinach or Sissoo.

Take a cutting or simple pull up and replant. It grows well in shade and sun. Sissoo will soon multiply and spread out but it’s not invasive.

The leaves are thin and dry and don’t produce the slimy or mucilaginous texture of other spinach-like greens.

Because it contains oxalates, it’s usually cooked by sautéing or steaming. Nutritional content unknown.

Newer leaves are more tender, the stems are not eaten but can be planted. This green is good in quiche, frittatas and can be blended with other garden greens listed here.

 

Edible Hibiscus (Abelmoschus maniho)

Another must have green is edible hibiscus.  These huge succulent leaves are great for wraps, soups, or sautéed. The leaves are high in vitamins A, C and iron.

They are related to okra and have that same slime, so I don’t recommend them for eating in salads, but if you don’t mind, go for it. The leaves thicken soups like okra. I like to sauté with chopped garlic, soy sauce and balsamic vinegar.

Easy to grow from cuttings, just cut a branch and bury in the soil and keep well watered until it starts to root. The bush tends to get overloaded and the branches will break off from the weight –just replant.

The large African snails like them and you can tell when they’ve munched on the leaves because they will look like lace and the trunks will have chew marks on them. If this happens, go around in the early morning, while wearing gloves pull them off and smash them. The snails are carriers of rat lung so be careful and do not handle the snails or eat any damaged leaves.

Okinawa Spinach (Gynura bicolor)

Okinawa Spinach

Okinawa spinach is another easy-to-grow green. It is delicious and brightens up any raw dish with the beautifully purple-colored leaf undersides.

One of my favorites because it is delicious and rich in iron and potassium, calcium, and vitamin A.

It goes to seed regularly and can either be planted from seed or cuttings. It loses its purple color when cooked but it has a distinct flavor that can’t be missed in stir fries and sautes. It also comes in a strictly green leaf but I prefer the purple variety.

 

 

Chaya (Cnidoscolus aconitifolius)

Chaya

Chaya or tree spinach is an edible green that grows into a small, woody bush and often grows best supported by a fence or protected from wind. Chaya is a good source of protein, vitamins, calcium, and iron; and is also a rich source of antioxidants.

New plants can be grown easily from cuttings. The leaves must be cooked and are toxic raw. I have lacto-fermented raw leaves and used them as one would grape leaves in making dolmas. I often roughly chop them and add them to sautes and stir fries.

The leaves are very plentiful and just a few plants will provide enough greens for a family.

Cranberry Hibiscus (Hibiscus acetosella)

Cranberry hibiscus

This green is not green at all but a beautiful cranberry color. It is pictured growing among some taro leaf.

This plant can be grown from cuttings or planted from the many seed pods. I have often cast out the seeds and they have self planted. Most typically, they will regrow in the same spot year after year.

The leaf has a citrus-like flavor and will brighten any salad with a pleasant tart-like flavor. High in vitamin C and traces of B-2 and B-3 vitamins. This can be cooked but I have always eaten it raw or made into a delicious tea. See Kumu Aina’s post on Make Fresh Herbal Tea from your Garden.

 

Sweet Potato Leaves (Ipomoea batatas)

Sweet potato

Sweet potatoes have abundant leafy vines and you can harvest their young leaves and shoots without damage to the sweet potato growing below in the soil. Even if you don’t plan to harvest the tubers, you can grow this vine just for the greens.

It is rich in vitamins A, B, C, the minerals calcium and phosphorus, antioxidants, iron and iodine. They can be added to salads or sautéed in stir fries.

 

Mustard Greens (Brassica juncea)

Mustard greens

This green seeds itself in my greenhouse. Honestly, I don’t even remember planting it. It happily goes to seed and grows in the understory of most vegetables. Occasionally, I have to pinch back a few leaves if it starts to over power things. The flavor of mustard greens is surprisingly refreshing and spicy. It has a hint of pepper and a mild bitterness. It is good sautéed or fresh in salads and especially piled high in sandwiches.

In the garden, it is helpful in reducing nematodes in the soil and shading out weeds. It us useful in removing heavy metals from soil, if removed when it starts to die off.

Mustard is high in Vitamin K, A and C. In addition, they are high in antioxidants and phytonutrients. Studies have shown, it is beneficial in removing toxic heavy metals from ones body. You can read more about the health benefits at this link benefits of mustard greens.

 

Purslane (Portulaca oleracea)

Purslane

Purslane has been growing in my greenhouse for 14 years and I have never planted it. A Hawaiian-based practitioner and author of medicinal plants, came to extract some from my garden a few years back and was surprised how freely it grew there.

Purslane is higher in beta-carotene than carrots, has more vitamin E than spinach and is higher in omega-3 fatty acids than some fish. It also helps the garden by loosening the soil with its roots enabling your other vegetables roots to grow deeper.

Picked early in the morning, helps it keep its nice tart flavor. Cook it lightly to retain most of its amazing benefits. I add it last to sautéed greens.

  1. Love this info. I used to pick purslane at the kapoho tide pools where it grew abundantly. Great in tossed salads. But, sadly, it’s covered in lava. Would like to get some for our place.

  2. Love this. I’ve heard that snails won’t call past copper mesh. Would a copper scrubby wrapped aournd the base of edible hibiscus keep them off? Just curious.
