Care Instructions

Light: Partial to full shade; gentle morning sun is acceptable. Protect from intense afternoon sun and reflected heat.

Water: Water regularly during Phoenix summers, keeping the root zone moderately moist but not soggy. Allow the soil surface to dry slightly between waterings; reduce watering in cooler months.

Soil: Well-drained soil amended with compost; tolerates varied soil types but struggles in compacted, waterlogged soil.

Mature size: About 12–18 inches tall, with trailing stems spreading 3–6 feet or more; can spread indefinitely where stems root.

Bloom: Primarily late winter through spring in Phoenix; occasional flowers may appear during other mild periods.

Evergreen / deciduous: Evergreen in Phoenix; exposed foliage may suffer damage during hard freezes or extreme summer heat.

Growth rate: Fast with adequate moisture and protection from extreme heat.
