Rose of sharon (Hibiscus syriacus) is a landscape plant native to Asia but very commonly planted in the US. It is a cold hardy tree or shrub with large tropical looking flowers, unmistakable once you’ve seen them.  Its edibility is often unknown, but there are a number of reasons to consider this plant for your next soup, salad, or sandwich.

Edibility And Culinary Use

The edible leaves of rose of sharon tree are available all spring, summer and fall.  They taste like lettuce but have a mucilaginous texture, which is pretty refreshing.  Because of this they make a great lettuce substitute in salads or sandwiches.  If you make your salad in late summer then you get the additional bonus of adding the edible flowers to the bowl.  They add some visual spunk, and the taste is great, mild, with a hint of nectar at the base of the petals. I also love to eat the unopened flower buds, they make a great alternative vegetable, eat them raw or cooked as a okra substitute.  The mucilaginous texture described above is a great thickening agent for soups, and sauces.  Another popular way to get the health benefits from this plant is to make a tea from the leaves and flowers.

Health Benefits

The number one health benefit known to science from consuming Rose of sharon tree is that it lowers blood pressure.  The plant is still being studied to determine what other benefits it may hold.  It does contain vitamin C, and anthocyanins which are antioxidants.

Japanese Knotweed Grove

We have all seen this plant growing along stream beds and in wet areas.  Japanese Knotweed (Polygonum cuspidatum / Fallopia japonica) is native to… you guessed it, Japan.  It’s also native to other parts of Asia.  This plant has naturalized in many parts of the world, it grows in 39 of the 50 United States and is listed as one of the world’s worst 100 invasive plant species by the World Conservation Union.  In other words there is no guilt in cutting down a Japanese Knotweed grove just to eat a few stalks. Another common name for this plant is Japanese Bamboo, because it grows with nodes similar to bamboo although it is not a bamboo.

Japanese Knotweed is a favorite wild edible to many people around the world because it is so easy to harvest and identify, and it tastes so good.  The stems can be eaten either raw or cooked when they are still juicy in the early spring, they get too tough to eat as the season progresses.   The taste is similar to rhubarb, sour and tart.  It can be used as a rhubarb substitute in pies. 

Health Benefits

The nutritional benefits of Japanese knotweed are that it contains vitamin A, vitamin C, potassium, phosphorus, zinc, and manganese. It also contains resveratrol which is a substance still being studied for its numerous health benefits. 

Key ID Features

Japanese Knotweet spreads by runners which send up stalks that can reach about 6′ in height.  The stalks are segmented by nodes every 6″-8″ similar to bamboo. There are 2 types of new growth in the spring, seed growth and runner growth.  Seedlings are small and thin.  New stalks originating from runner roots come up about 1″-1.5″ stem diameter, and they grow very quickly, these are the stalks that are usually eaten.

Cautions

Japanese Knotweed contains oxalic acid just like rhubarb, spinach and some other common vegetables. Oxalic Acid aggravates conditions such as rheumatism, arthritis, gout, kidney stones or hyperacidity.  So if your doctor has told you to avoid oxalic acid then avoid Japanese Knotweed.

Conclusion

This is a plant that can be harvested in large quantities. So unless your limiting your oxalic acid intake this plant should be part of everyone’s diet, it’s easy to find, identify, harvest, very good for you, and it tastes great. So next time you see Japanese Knotweed growing in a clean streambed in early spring think about taking some home.
