This page covers what makes purple heart different. For light, water, soil, pests, and the rest, read the tradescantia care guide.

What it is

Purple heart has long, narrow, solid purple leaves on trailing purple stems. The leaves have a light coat of fine hairs. In summer, small pink flowers open for one day each. It comes from Mexico, where it grows as ground cover. NC State Extension notes that its sap can irritate skin.

How to tell it apart

Inch plant Shorter, silver stripes Silver stripes on top
Purple passion Green with purple fuzz Fuzzy, green-based leaves

Care differences

Purple heart wants more light than other tradescantias. A few hours of direct sun keep it deep purple. In low light, it turns green and the stems stretch.

It does well outside in summer and comes back in for winter.

Grow it from a cutting

Cut a stem tip and root it in water or moist soil. Roots form in a week.

Pet safety

Purple heart sap can cause a red, itchy rash on skin. Keep it out of reach of pets.

Buying it

Purple heart is sold as both a houseplant and a summer annual at garden centers. Look for deep purple, full plants.
