📏

Spacing: 12-18 inches apart for ground cover effect inches

📅

Days to maturity: 30-60 days to first flowers; fills in as ground cover over 1-2 growing seasons

🌱

Planting depth: Surface sow seeds or plant transplants at same depth as root ball; seeds need light to germinate

Growth Stages

Seedling

2-3 weeks

Tiny heart-shaped cotyledons emerge; first true leaves appear heart-shaped and small

Keep soil consistently moist; provide bright, indirect light; maintain 60-70°F for germination

Vegetative

4-8 weeks

Plant develops branching stems with opposite, heart-shaped leaves; variegation patterns (if variety has them) become apparent

Pinch back growing tips to encourage bushier, more spreading growth; water regularly; fertilize monthly with balanced fertilizer

Flowering

4-12 weeks (spring through early summer, may repeat in fall)

Two-lipped flowers in whorls appear along stems in colors ranging from pink to purple to white, depending on variety

Deadhead spent flowers to encourage prolonged blooming; continue regular watering; stop pinching to allow flower production

Spreading/Ground Cover

Ongoing through growing season

Stems spread horizontally and root at nodes; plant fills in desired area creating dense carpet of foliage and flowers

Remove any dead stems; thin occasionally to prevent excessive matting; no deadheading necessary if seeds are desired

Dormancy/Winter

3-6 months depending on zone

In cold climates, foliage may die back; in milder zones, variegated types retain color and remain evergreen to semi-evergreen

Reduce watering in winter; no fertilizing needed; in zone 3-4, provide mulch protection; cut back dead foliage in early spring
