When the weather starts to get cold, growing ornamental kale can be a great way to add a splash of color to your fall and winter garden. But you may be wondering whether or not it’s safe or enjoyable to eat. Let’s discuss!
What Is Ornamental Kale?
Ornamental Kale (Brassica oleracea var. acephala) is part of the Brassica family, along with cabbage, broccoli, brussels sprouts, and cauliflower.
Genetically, it’s the same as the culinary type that we love to eat. However, it’s been hybridized to look more like a flower with purple, pink, and/or white leaves.
Sometimes mislabeled as ornamental cabbage, you can tell the difference by looking at the leaves: kale is curly or ruffled, whereas cabbage has leaves that are broad and smooth.
Ornamental kale is liked by gardeners who want to add some color to their fall and winter gardens and containers, as it grows well in cooler weather. In fact, the colors become their most vibrant once night temperatures start dropping below 60°F. However, these colors will start to fade once nighttime temperatures start dropping to 20°F and colder.
In addition to providing a pretty addition to your garden, you may be wondering if there’s any potential nutritional benefit to these “ornamental” plants. Let’s take a look, shall we?
Is It Edible?
Apart from their looks, a key difference between this and the leafy greens you buy at the grocery store is that this variety isn’t grown for flavor.
As a result, the ornamental stuff is much less flavorful than the “edible” culinary leafy greens. However, the leaves of these varieties are safe to eat. Just make sure to stay away from the roots, which are poisonous in any type of kale.
A Note of Caution
Ornamental kale plants purchased at a nursery may not have been grown organically, and there is a chance that they may have been sprayed with potentially toxic chemicals including pesticides or herbicides that are not food safe.
If you’re unsure if they’re safe to eat, it’s better to err on the side of caution and use these plants only for decorative purposes.
The main difference is that the leaves of the more decorative cool-season garden favorite are much more bitter than those of the varieties you’d typically grow for eating.
Still, if you’re interested in eating the more decorative plants from your garden, you can decrease some of the bitterness by boiling the leaves before adding them to recipes like casseroles or a stir-fry.
If bitterness isn’t your thing, but you don’t want those beautiful leaves to go to waste, you can use them as a garnish, or plate other foods on top for an impressive presentation.
Ornamental Kale Is Rich in Nutrients
In addition to being safe to eat, the leaves of this plant are also nutritious.
As is the case with ‘Lacinato,’ ‘Russian Red,’ curly-leafed, and other culinary varieties, the ornamental variety is also a good source of vitamins A, C, and K, as well as calcium and various antioxidants.
In fact, a study published in the journal BMC Genomics found that those bright splashes of pink and purple are due to compounds called anthocyanins.
A review published in the journal Nutrients found that diets rich in anthocyanins are associated with a reduction in inflammation, obesity, and obesity-related chronic diseases.
More Than Just Pretty to Look At
Colorful and decorative, the ornamental variety is a beautiful addition to a fall or winter garden that also happens to be edible. However, as it can be quite bitter, it’s not for everyone. If you do decide to eat it, make sure that it hasn’t been sprayed with any potentially toxic chemicals and rinse the leaves really well!
