Tradescantia is the genus. Inch plant, wandering jew, and wandering dude are common names for the same trailing houseplants, including Tradescantia zebrina and Tradescantia fluminensis. UF/IFAS still lists Zebrina pendula as wandering Jew / inchplant (now Tradescantia pendula). Those stay on this URL.
NCSU: stem cuttings. UF/IFAS: stem cuttings, which root easily. Illinois lists stem only, not leaf. Missouri: very easy, and it may be rooted in water.
NCSU: the nodes sit about an inch apart. That is the “inch” in inch plant. Stems root at those nodes. UF: stems root wherever they touch soil.
For mix in a drained pot, see soil propagation. Water lives on water propagation.
Stem cuttings
NCSU on T. zebrina: trim the long stems in spring. Those pieces are the cuttings.
Iowa’s stem-tip houseplant page lists Tradescantia and Zebrina (inch plant, wandering dude) with that list’s general recipe: 3 to 6 inches, at least two nodes, lower leaves off, flowers off if present, hormone optional, at least one node in the media and no buried leaves. Most houseplant stem cuttings on that page form roots in 3 to 6 weeks. Early spring is ideal; any time of year can work. Those inches and weeks are the list page, not a Tradescantia-only trial.
Missouri: a herbaceous cutting. Very easy. May be rooted in water.
UVM Extension names inch plant (Tradescantia zebrina) among vining plants that are easy to root in water. On that same page, a general cutting is 3 to 6 inches with several nodes; strip 1 to 2 nodes at the bottom; room-temperature water; no leaves under the surface; pot when roots are more than 2 to 3 inches. Time on that page is “days or weeks, sometimes months,” for houseplants in general. Do not treat it as an inch-plant week count.
Illinois’s general stem recipe is 3 to 6 inches, two to six nodes. Tradescantia and Zebrina are both marked stem.
Layering
Iowa lists Tradescantia for simple layering, not air layering. Flexible stem. Pin or bury at least one node, 2 to 4 inches deep, in soil, perlite, or sphagnum. Leaves off the buried stretch. On that page, new roots in 6 to 12 weeks, maybe longer depending on the species. Cut free when the stem is firmly rooted.
That matches what UF describes outdoors: stems root where they touch soil. Indoors, the same node can be pinned into a second pot.
Common mistakes
- A leaf with no node. Illinois, NCSU, UF, and Iowa list stems. The roots come from the node.
- Treating UVM’s “days or weeks, sometimes months” as an inch-plant timetable.
- Averaging Iowa’s 3 to 6 weeks (stem-tip list) with Iowa’s 6 to 12 weeks (simple layering).
- Filing this as a succulent because the stems are fleshy. It is not on the succulents cluster.
People also ask
Wandering jew or inch plant?
Same URL. NCSU uses inch plant and wandering dude for T. zebrina. UF uses wandering Jew and inchplant for the striped trailer. T. fluminensis is the green or white-flowered inch plant. Stem cuttings either way.
Water or mix?
Missouri names water. UVM names inch plant as easy in water, and also describes mix. Iowa’s named list is stem tips in media. Keep the names.
How long until roots?
Iowa stem-tip list: 3 to 6 weeks for most houseplants on that page. Iowa simple layering: 6 to 12 weeks. UVM does not give an inch-plant week count. Those are not one number.
