Can Hostas be Consumed? Guidelines for Harvesting and Preparing a Popular Perennial Plant
In the world of edible plants, a unique and intriguing candidate has emerged: the humble hosta. Originating from East Asia, particularly Japan, these plants have been harvested for centuries and are known as "sansai," or mountain vegetables.
Hostas are known for their early shoots, called "hoston," which are the young leaves that curl up from the soil in spring. These are considered the best part for consumption, as they offer a delightful taste, with the Montanas being said to be the tastiest variety.
The flavour profile of hostas is slightly bitter, but pairs well with sweet, smoky flavours. Thicker hoston leaves can be pan-seared or gently braised, while smaller leaves can be stir-fried and seasoned with sesame oil and soy sauce. For those who prefer a more familiar texture, whole, larger hostas can be boiled, much like asparagus.
To enjoy hostas at their best, it's crucial to source leaves that have not been exposed to chemicals like herbicides or pesticides. Harvesting them in the morning ensures the freshest taste. Before use, washing and drying the leaves is essential to prepare them for various uses, such as treating them like lettuce or spinach, chopping them into a salad, or using them like frozen spinach by blanching, drying, and freezing them.
When it comes to storage, hosta leaves can be kept whole or divided from the cluster. They can be stored for 2 days in the vegetable crisper drawer, layered with paper towels in a plastic tub or baggie. If stored for more than a couple of days, hosta leaves will get wilted.
Hosta flowers are also edible and can be used as an edible garnish or tossed in a salad. They have a mild pepper flavour, adding an interesting twist to dishes.
It's important to note that hostas are a shade to partial shade foliage plant with little fairy-like purple to white flowers. They grow from rhizomatous roots and begin to produce tightly furled leaves in early spring.
Foraging for hostas is a traditional practice primarily in regions of East Asia, such as Japan and Korea. However, it's essential to remember that any foraged foods should be washed thoroughly before use.
So, the next time you're in the garden, don't forget to give hostas a second glance. They might just become your new favourite ingredient in the kitchen!
