Moses-in-the-cradle Breakdown
Appearance:

The name “Moses-in-the-Cradle” comes from the tiny white flowers that emerge from boat-shaped bracts nestled in the leaf axils.

Full sun to partial shade.
In bright indirect light, the leaf color will be more vibrant. In too much shade, growth may become leggy, and color can fade.

Maintenance:
Low.
Remove old or yellowing leaves to keep the plant tidy. Prune back overgrown clumps to encourage fuller growth. Can be propagated easily by division.

Excellent as a groundcover, border plant, or in container gardens.
It works well in tropical or subtropical designs and pairs nicely with other bold foliage plants.

Hardy in USDA zones 9–11.

Frequently Asked Questions
How to Plant & Care for Moses-in-the-cradle in Florida
Choose Sun + Spacing
Most Florida plants prefer full to partial sun. Check mature width and space accordingly so plants don’t crowd as they fill in.
Dig Wide, Not Deep
Dig a hole 2–3x wider than the container and slightly shallow. This encourages roots to spread outward into native soil.
Plant at Proper Height
Remove from the pot, loosen circling roots, and plant with the root ball level to slightly above grade.
Water to Establish
Water deeply right after planting. For the first 10–14 days, consistent moisture is critical—don’t let the root ball dry out.
Mulch + Light Maintenance
Apply 2–3 inches of mulch (keep off the stem). Once settled, light trimming encourages fuller growth.
