Today I wanted to cover a very common garden plant that is also a traditionally eaten vegetable in Japan.

You might not think of them as a food plant, but they’re a pretty good one to add to your diet when most other greens are bitter or sparse.

Let’s take a look at the humble hosta:


Plant Profile:

Scientific Name: Hosta sp. (Hosta capitata, Hosta kiyosumiensis, Hosta sieboldiana among others)

Preferred Habitat: Partial or full shade is actually the preference of hosta species. Sometimes full sun is fine for them as well. In North America hostas tend to be found in modern landscaping primarily, not so much in the wild. In my experience they tend to prefer moist areas that have a decent ratio of organic matter in the soil.

Edible Parts: Young shoots, flowers.

Distribution: Largely the eastern half of the United States is where they’re distributed outside of their normal range (in Asia).

Harvest Season: Spring

Nutrition:

For such a common plant, especially one that is consumed traditionally in Japan, you’d expect there to be more information on the nutrition profile of hosta.

Unfortunately all I can provide is that it contains:

  • Decent fiber content

  • Some vitamin C (hopefully a lot?)

  • Minerals like potassium and calcium

  • Various phytonutrients and antioxidants

Yet another plant that could benefit from some nutrient research! (Seriously, there are not enough people researching this kind of thing).

Uses

Hosta is really only edible as young shoots before the leaves have started opening.

This isn’t because of any danger, it’s just because the plants tend to get fibrous and unpleasant to eat as they get older.

This is actually the first year I’ve eaten hosta shoots! I did this just for you guys so I can give you an accurate and fresh take on the flavor profile. My overall opinion is that they’re a great vegetable for something that is so little effort as well as a perennial!

Firstly, we ate them cooked, however you can eat them raw as well with no risk. They have a slight bit of mucilage in them (like okra but not even remotely as much) but that seems to go away quite a bit when cooked.

The flavor is very mild and mostly bland, similar to romaine hearts. I had heard before that they taste slightly like asparagus and this is true but I think the only hint of asparagus flavor mostly comes from the aroma when they are cooked.

So there you go; romaine hearts with a hint of asparagus! They pair well with strong or salty sauces as they are traditionally eaten in Japan as a vegetable (known as “urui”).

The shoots can be eaten raw, fried, boiled, dipped in sauces, used in soups, or simply eaten as a side dish. We found that they would probably pair well with ramps and other onions.

The flowers can also be eaten apparently, but that’s mostly to add beauty to a dish since they taste somewhat astringent and bland.

Growth Habits

Hostas will start shooting up out of the ground in spring (for me it’s in the first week of May that they’re tall enough to harvest). This is around the time you’ll start to get the spring greens coming up so it really adds something to your bounty.

They grow quite fast though so I’d keep a close eye on any that you want to harvest!

Most mature hosta clumps can not only handle some pruning, but can actually benefit from thinning so harvesting won’t harm the plant! Some hosta growers actually cut back the first shoots completely since it encourages a second flush of shoots to sprout.

Hostas can also be divided when the clump is large enough (I’ve split clumps as small as 8in across).

In the summer, they grow tall stalks with small cone-shaped flowers along them.

Additional Information

When I was younger, I remember planting hostas with my mom at our old house and I remember desperately wanting to own elephant hostas after seeing them in other people’s yards and realizing I could crawl underneath the large foliage!

These are a pretty easy vegetable to get your hands on and to grow, so I recommend it if you want a fresh taste of spring.

I would say that your options are limited to some degree with finding vegetables that grow well in shade, so I like that hosta fills that niche pretty nicely. They are also harvested fairly early in the spring which is nice. I definitely recommend them for the average gardener!

Cultivars

There are over 3,000 cultivars of hosta available worldwide so you have a lot of options!

While there are many species and hybrids, I will just list whatever the cultivar is (most sites will say what species or cross their varieties are anyway).

Let’s look at a few that I’ve decided to highlight:

  • Mouse Ears - This is a miniature hosta variety that stays compact. This is perfect for small spaces and I could see tiny hosta shoots as a gourmet ingredient. The leaves are a gray-green color and the flowers are a lavender color.

  • Paul’s Glory - This variety, like many other hosta varieties, has variegated leaves with a bold yellow in the center, and a deeper green around the edges of each leaf. This variety is a classic and is fairly large as far as hostas go.

  • Praying Hands - This variety is more slender and the leaves remain somewhat folded inward. My suspicion is that this may have taller shoots and they may last a bit longer before opening up but that is untested as of now. Try them out!

  • Frances Williams - This is a large classic hosta that has a deep blue-green in the center of the leaves and a neon yellow-green around the edges. Flowers are white.

  • Guacamole - A very large clumping variety that likes to spread out and fill space quite a bit. If you need to fill a shady area quickly, this one’s your guy!

  • Empress Wu - This variety is very large (considered a ‘giant’ hosta) and has dark foliage. This might be another good one for long shoots depending on when it starts to open up.

  • White Feather - This is a uniquely white hosta with narrow leaves. I would describe this plant as being almost angelic or ethereal. It is a very slow-grower (having very little clorophyll) and does best in more sun than others, but I thought I’d include it since it has some interesting traits and looks very pretty.

  • Dancing Queen - I love this variety (and no, not just because I like ABBA) it has bright green foliage and is a larger leafed cultivar that adds a brightness and warmth to otherwise cool or dark shade gardens.

  • Montana - There are actually several ‘Montana’ cultivars. I wanted to include this species since they are considered to be some of the better ones for eating.
