Annual vs. Perennial: Decoding the Kale Mystery
In the realm of gardening, knowing whether a plant is classified as an annual or a perennial is crucial. Annual plants need to be replanted each year, while perennials continue to grow year after year. However, kale doesn’t neatly fit into either of these categories. Instead, it belongs to a group known as biennials.
Biennial plants like kale complete their life cycle over two years, with each year bringing forth different stages of growth and development. In the first year, biennial kale focuses on leaf production, thriving in optimal growing conditions and producing lush foliage.
In USDA Hardiness Zones 7 to 10, biennial kale can continue to yield edible leaves throughout the winter months. In colder zones, the plants may go dormant during winter, with the root systems remaining alive to sprout new growth when the conditions become more favorable.
Unveiling the Perennial Kale Varieties
While most kale varieties you encounter will belong to the biennial category, there are some perennial cultivars that add an exotic touch to your garden. Let’s explore a few of these perennial kale varieties:
Daubenton (B. oleracea var. ramosa)
Named after a French naturalist, ‘Daubenton’ is a short-lived perennial kale variety that does not produce seeds and is instead propagated through cuttings. This cultivated variety can live for five to six years in USDA Hardiness Zones 6 to 9, withstanding temperatures down to 10°F.
The leaves of ‘Daubenton’ kale are mild and nutty in flavor, making them less bitter compared to their biennial counterparts. To keep this variety thriving in your garden, propagate it from root cuttings as the plant nears the end of its life cycle.
Walking Stick (B. oleracea var. longata)
Also known as Jersey cabbage or tree cabbage, ‘Walking Stick’ kale originates from the Channel Islands and boasts long, sturdy stalks that were traditionally repurposed into walking sticks. This perennial kale thrives in USDA Zones 6 to 9 and can withstand temperatures as low as 10°F.
With proper care and harvesting techniques, ‘Walking Stick’ kale can grow tall, reaching heights of up to 20 feet under favorable conditions. The leaves are used for culinary purposes, imparting a sweet and nutty flavor to dishes when cooked.
Sea Kale (Crambe maritima)
A unique member of the Brassicaceae family, Sea Kale is a distant relative of kale that grows wild along Northern European coastlines. Hardy in Zones 6 to 9, this perennial plant flourishes in sandy soils, making it an ideal choice for coastal regions.
When blanched during growth, the young shoots and leaves of Sea Kale develop a pleasant nutty flavor when cooked. Although germination rates from seeds may be low, this plant offers an exciting option for perennial vegetable gardeners looking to expand their culinary repertoire.
