Spiderwort, belonging to the genus Tradescantia, is a captivating plant with around 75 species known for their erect to trailing weak-stemmed nature. These plants are native to the Americas and are celebrated for their easy culture and popularity as indoor plants due to their ability to take root readily from cuttings. Spiderworts can also serve as ground cover in warm climates, thanks to their resilience and adaptability.
One of the intriguing aspects of spiderwort is its naming origin, which is believed to be inspired by the spider-like appearance of its flowers, featuring delicate flowers with three petals and six stamens extending out like spider legs. Spiderwort comes in a variety of striking colors, including deep blues, purples, pinks, whites, and even bicolor varieties, providing a stunning array of options for gardeners.
When it comes to care, spiderwort is known for its resilience and ease. It can thrive in a range of soil conditions, preferring moist, well-draining soil with a high humus content and a slightly acidic pH. While it can withstand a wide range of sunlight conditions, partial shade is preferred for optimal growth. The plant requires minimal fertilizing, with a couple of applications at the start of its growing period being sufficient. After blooming, spiderwort may require pruning to prevent it from becoming leggy and to encourage healthier blooms.
There are over 70 known species within the Tradescantia genus, each sharing similar characteristics but varying in size from 6 inches to 3 feet tall. The most commonly grown species is the Virginia Spiderwort (Tradescantia virginiana). Other notable varieties include Zigzag Spiderwort (T. subaspera), Ohio Spiderwort or Bluejacket (T. ohiensis), and Hairy-stemmed Spiderwort (T. hirsuticaulis), among others.
Spiderwort is also recognized for its low toxicity, posing little danger to humans and pets, although its leaves and sap can cause skin irritations in sensitive individuals. Traditionally, it has been used by First Nations tribes in culinary and medicinal capacities, with seeds being cooked and pulverized into powder and vibrant flowers being consumed fresh.
For those looking to propagate spiderwort, it's an easy task that can be achieved by dividing clumps of plants or taking stem cuttings, making it a popular choice for expanding garden collections. Moreover, while some Tradescantia species are known to cause contact dermatitis in certain individuals, they are generally considered safe and easy to grow as houseplants or outdoors in appropriate climates.
In summary, spiderwort is a versatile and attractive plant that offers beauty, ease of care, and a variety of uses, making it a valuable addition to any garden or indoor plant collection.
