Plant Profile & Care Advice
Origin & Cultivation History
Nasturtiums, scientifically known as Tropaeolum majus, trace their vibrant lineage to the mountainous regions of South America, specifically the Andes. Indigenous peoples cultivated these lively annuals long before their introduction to Europe in the 17th century. Their journey across the Atlantic marked the beginning of their widespread popularity as both an ornamental and edible plant. The genus Tropaeolum is derived from the Latin word "trophaeum," meaning trophy, referencing the shield-like leaves and spur-like flowers, which were thought to resemble ancient warrior's helmets and shields. Nasturtiums thrive in conditions ranging from full sun, which encourages prolific flowering, to partial shade, where they may grow more luxuriantly but with fewer blossoms. This adaptability has made them a beloved garden fixture worldwide.
Gardening Tips & Culinary Uses
Cultivating nasturtiums is a rewarding endeavor for gardeners of all skill levels. They prefer well-draining soil and are surprisingly tolerant of poor, even sandy, conditions; in fact, overly rich soil can lead to abundant foliage at the expense of flowers. Water moderately, allowing the soil to dry slightly between waterings. Nasturtiums are easily grown from seed, which can be sown directly outdoors after the last frost. For prolific blooms, avoid excessive fertilization. Their bright, peppery leaves and blossoms offer a delightful addition to the culinary repertoire. Young leaves can be tossed into salads for a zesty bite, while the flowers provide a beautiful garnish. The flower buds can also be pickled, offering a caper-like flavor. Beyond the kitchen, nasturtium extracts have been traditionally recognized for their potential health benefits.
