Solid, striped, or variegated; burgundy, emerald, lilac, and (sometimes or) white; and almost always pointed. The leaves of Tradescantia species come is a vast array of appearances and hues which dazzle the eye and draw many a plant-lover near. Now, these unique descriptions may cause you to believe that these lovely specimens are rare pieces of small gardening collections hoarded away from the eye of the general public; however, it is rather likely that you have encountered at least one cultivar of this ever-popular genus in your wanders through the wilds of your local gardening center.
All About Tradescantia
Known more widely as inch plant, spiderwort, or “wandering jew,” Tradescantia are a genus of around seventy-five perennial flowering plants native to the regions between Canada and mid-South America. The genus became more well-known during the 1600s, during which foreign trade introduced the prior unknown beauties to Europe. It was during this very same period that the genus’s popularity began to take root and, subsequently, these colorful, winding wonders trailed their way into the hearts of green thumbs and the environments of locales across the globe. This, unfortunately, has caused some species to become invasive and cause unrest in those ecosystems where it survives a little bit too successfully.
(A kind thanks to Wikipedia for giving me the most quintessential knowledge I can’t seem to dig up on more “academic” sites!)
If you are anything like me, you are likely wonder why in the dickens these plants are known as “wandering jews.” Jackie Rhoades of Gardening Know How shares the story of the namesake in the post “Growing Wandering Jew Houseplants.” Simply put, women of the home we quite adept at growing the plants and would share their clippings with one another, thereby allowing the houseplant to spread in a manner similar to that of historic members of the Jewish community.
Care
Tradescantia are widely known to be of insubstantial need; they are, in nature, wildflowers which trail and vine, after all. Despite the this self-preserving, low-maintenance facade, though, some small eccentricities have slightly swayed the genus’s total ease of care and necessitated a tidbit of attention on the part of jungle caregivers.
For Tradescantia, the most basic requirements, soil, is of equally basic need. Genus members grow best in a well-draining general purpose potting soil, but they can also do extremely well in soilless mediums as a result of their abilities to drain. Container size is not typically an issue and many cultivars can be placed in hanging baskets or pots one size up from their nursery pots to contain their growth.
One such peculiarity comes in relation to the watering preferences of the plants: they really don’t like wet feet and really, really don’t like to be watered at the base of their stems, known as the crown of the plant. At this point, you have probably heard my spiel about root rot and how plants (usually) don’t like to have water sitting in their containers; this also applies to Tradescantia. Beyond these small finicky pieces, the genus likes to be watered deeply, drained well, and misted to raise the surrounding humidity. During the dormant season (winter), watering should be reduced to accommodate for the plant’s growth stagnation, though.
Fertilization of the plant is not entirely necessary, but can be done up to twice monthly with a diluted solution of general-purpose houseplant fertilizer.
The sunlight and temperature requirements of Tradescantia are straightforward. All members of the genus prefer bright, indirect sunlight with the occasional glance of full exposure and all will grow steadily in temperatures ranging between 55 and 75 degrees Fahrenheit.
Unfortunately, Tradescantia are known be become elongated and “leggy” with time due to their trailing nature. Many growers, including The Spruce, suggest pinching the plant to encourage branching of the plant and ensure fullness. When the plant becomes too stretched, though, the issue can be addressed by taking plant cuttings, rooting them in water on a sunny window sill, and replanting when the new roots have grown to one inch in length.
