Yellow Dot

Name: Yellow Dot
Brand: Outdoor Dream Builders

Sphagneticola trilobata

A fast-spreading tropical groundcover with cheerful yellow daisy flowers that can be invasive and is a skin irritant.

A tender tropical hardy in USDA zones 9-11; it freezes to the ground in the low 20s°F and returns each spring, thriving in low-desert heat but flagging without regular water.

AMWUA Notes

Skin irritant — wear gloves when handling. Can be invasive; contain in planters.

Care Guide

💧Watering

Water every 5-7 days in summer for a lush tropical look; it is one of the thirstier groundcovers here and wilts quickly when dry, though it tolerates poor soils.

✂️Pruning

Shear aggressively and often to contain its fast creeping stems, which root wherever they touch soil; edge or barrier it to prevent unwanted spread.

🌱Fertilizing

Rarely needs fertilizer; it grows vigorously on its own, so avoid feeding that fuels invasive spread.

🛡️Pests

Few pests; the real management issue is its invasiveness plus foliage that can irritate skin, so wear gloves.

☀️Seasonal Notes

Cheerful yellow daisies appear spring through fall; foliage freezes back in the low 20s°F and regrows rapidly once heat returns.

Soil, Feeding & Propagation

🪨Soil

Grows in most soils including poor and moist ground; tolerant of a wide range but wants steady moisture.

💧Drainage

Needs moderate soil.

🌱Nutrient Needs

Low feeder.

🌰Propagation

Cuttings root instantly; every node roots where stems touch soil, which drives its invasiveness.

📐Spacing

2-3 ft on center, ideally within containers or a root barrier

🌳Roots & Placement

Aggressively invasive — stems root at every node and it escapes into turf, beds, and natural areas; confine to containers or install a root barrier.

Placement Tips

•Best grown in containers and raised planters where its aggressive spread is physically contained.
•If used in the ground, install a root barrier and keep it well away from turf, beds, and natural areas.
•Space 2-3 ft apart for a fast tropical-style filler in an oasis zone.
•Give full sun and steady moisture; wear gloves when trimming.
