The Tradescantia, commonly known as the Wandering Jew, is a fast-growing houseplant known for its vibrant, multicolored foliage and vigorous, cascading growth habit. Many plant owners wonder if they should provide vertical support for these vines. The answer depends on understanding the plant’s natural growth mechanics, which differ significantly from true climbing species.
Understanding the Wandering Jew’s Growth Habit
The natural growth pattern of Tradescantia is not upward climbing but rather horizontal or downward trailing. In its native environment, the plant acts as a groundcover, spreading across the forest floor or rocky terrain. This spreading behavior is supported by the plant’s soft, fleshy stems and unique rooting structure.
The stems of the Tradescantia are characterized by prominent nodes, which are the points where leaves emerge. When these nodes come into contact with moist soil, they readily produce new roots, a process known as nodal rooting. This mechanism allows the plant to quickly anchor itself and colonize new areas.
Because the stems are relatively delicate and designed to lie down or hang, they lack the structural rigidity necessary to push upward against gravity. This trailing and rooting pattern is fundamentally different from the way other vines seek out vertical support. Attempting to force the plant to climb a plain support structure may result in the stems buckling or breaking under their own weight.
The Function of Moss Poles and Aerial Rooting
A moss pole is a specialized support structure designed for epiphytes, such as Monstera, Pothos, and Philodendron. These plants use a distinct biological mechanism to climb. The primary purpose of a moss pole is to mimic the structure of a tree trunk in a tropical forest.
True climbing plants possess specialized structures called aerial roots, which emerge from the nodes along the stem. These roots are not primarily for water uptake from the soil. Instead, they function to physically attach the plant to a vertical surface and absorb moisture and nutrients directly from the air. Keeping the pole moist encourages these aerial roots to penetrate and anchor the vine firmly as it grows upward.
The Tradescantia does not produce specialized aerial roots for climbing. The roots it produces at its nodes are meant to establish a new, independent plant when they reach the soil. Placing a Tradescantia against a moss pole will not naturally encourage it to climb or benefit from the pole’s moisture-retaining function. The plant will still need to be manually tied to the pole, and its roots will not anchor themselves into the moss.
Appropriate Support Methods for Trailing Plants
Since the Tradescantia is naturally a trailing plant, the most suitable display method is to embrace its cascading habit. Placing the plant in a hanging basket or on the edge of a high shelf allows the stems to flow downward freely. This also prevents the lower leaves from becoming crushed or damaged.
If the goal is to manage the plant’s spread, simpler supports are more effective than a moss pole. Simple bamboo stakes or small trellises can be inserted into the pot to help keep the central base of the plant upright and tidy. The stems must be loosely tied to these supports using soft plant ties or clips, as they will not naturally cling.
Another method for maintaining a dense, controlled shape is regular pruning and propagation. Trimming back the long, leggy stems encourages the plant to produce new growth closer to the pot’s center, resulting in a fuller, bushier appearance. The trimmed stems can then be rooted easily in the same pot.
