Chartreuse Coleus

Plectranthus scutellarioides 'Chartreuse'

flower

Chartreuse Coleus is a vibrant foliage plant prized for its bright yellow-green to lime-colored leaves that add luminous color to gardens and containers. Unlike most coleus varieties that require shade, chartreuse cultivars perform best in bright, indirect light where their color intensifies. This tropical perennial is typically grown as an annual in cooler climates and reaches 12-24 inches tall.

Growing Conditions

☀️

Sun: Bright, indirect light to light shade; 4-6 hours of morning sun. Unlike dark coleus, chartreuse varieties tolerate and benefit from more sun (up to 6-8 hours) but may fade in full afternoon sun

💧

Water: Keep soil consistently moist but not waterlogged. Water when top inch of soil feels dry. More frequent watering needed in containers and hot weather. Reduce watering in winter dormancy

📏

Spacing: 12-18 inches

📅

Days to maturity: 30-45 days to reach usable size; 60-90 days for full mature plant

🌱

Planting depth: Surface sow or barely cover seeds; transplants planted at same depth as container

Soil

Type: Well-draining, fertile loamy soil

pH: 6.0-6.5

Amendments:

Compost or aged manure Peat moss or coconut coir Perlite for drainage

Growth Stages

Seedling

2-3 weeks

Tiny cotyledons emerge, followed by small lime-green true leaves. Plant is delicate and pale

Keep soil warm (70-75°F), moist, and under bright indirect light. Provide 12-14 hours of daily light. Protect from direct sun and cold

Vegetative Growth

4-8 weeks

Compact plant with increasingly larger, bright chartreuse leaves. Stem branches readily, creating bushier form. Foliage color intensifies with proper light

Pinch growing tips every 2-3 weeks to encourage bushiness. Maintain consistently moist soil. Provide bright indirect light. Feed every 2 weeks with balanced fertilizer

Mature Foliage

Ongoing as long as conditions maintained

Plant reaches full size (12-24 inches) with lush, dense chartreuse foliage. Leaves are fully sized and color is vibrant. Plant may produce small purple or lavender flower spikes

Continue pinching tips to maintain shape and prevent flowering. Water consistently. Ensure adequate light to maintain chartreuse color. Fertilize monthly

Flowering (Optional)

Variable; can be suppressed with regular pinching

Small spikes of purple, lavender, or white flowers appear in leaf axils. Flowering is often undesirable as it redirects energy from foliage production

Pinch off flower buds as they appear to redirect energy to leaf growth and color production. If flowering occurs despite pinching, remove spent spikes

Decline/Dormancy

October-March in cooler climates; year-round in tropical zones

In cooler climates, plant slows growth in fall/winter. In zones 10-11, growth continues but may slow. Leaves may lose some vibrancy with reduced light

Reduce watering frequency in winter. Move containers to brightest available location. Can be cut back and overwintered indoors. Reduce fertilizing

Companion Planting

Plan your garden →

Plant with:

Impatiens Begonias Hostas Ferns Caladiums Shade-tolerant ornamental grasses Heuchera

Avoid planting near:

Plants requiring full sun and dry conditions Drought-tolerant plants like sedums and succulents Aromatic herbs like rosemary and lavender

Common Pests

Mist foliage regularly to increase humidity. Spray with neem oil or insecticidal soap weekly. Remove heavily infested leaves
Isolate affected plant. Dab insects with rubbing alcohol on cotton swab. Spray with neem oil every 7-10 days for 3-4 weeks
Use yellow sticky traps. Spray undersides of leaves with neem oil or insecticidal soap. Improve air circulation
and
Remove by hand in early morning or evening. Use copper tape around pots. Set beer traps. Apply diatomaceous earth around base
Ensure excellent drainage. Allow soil to dry slightly between waterings. Remove affected plant portions. Repot in fresh, sterile soil

Uses

🏠

Container and garden accent

Household

Chartreuse Coleus serves as a stunning container plant and garden focal point, providing bright yellow-green foliage that brightens shaded areas and contrasts beautifully with darker-leaved plants. Its luminous color adds visual interest to patio containers, window boxes, and mixed borders [source]

🎨

Leaf propagation and plant propagation

Craft

Coleus is exceptionally easy to propagate from stem cuttings placed in water or moist soil, rooting within 1-2 weeks. This makes it perfect for sharing with gardeners and for creating multiple plants from a single parent [source]

🏠

Indoor houseplant

Household

Chartreuse Coleus grows beautifully indoors on bright windowsills, providing year-round tropical foliage color. It helps purify indoor air and is non-toxic to humans, though safe to handle [source]

🦋

Pollinator attraction

Wildlife

When coleus flowers, the small flower spikes attract bees and other pollinators, supporting local pollinator populations. Though flowering is often suppressed for foliage beauty, allowing some flowers to bloom benefits the garden ecosystem [source]

💊

Traditional herbal uses

Medicinal

Coleus species have been used in traditional Ayurvedic and Southeast Asian medicine, though research is ongoing. Some relatives of Plectranthus contain compounds of interest in phytotherapy [source]

Harvest Tips

Chartreuse Coleus is grown for foliage rather than harvest. Pinch growing tips regularly (every 2-3 weeks) to harvest tender shoots for propagation and to maintain bushiness. Pinching encourages branching and maintains vibrant color. Remove any flower spikes immediately to direct energy to leaf production. In containers, can be harvested continuously throughout growing season

Fun Facts

🌱 Chartreuse Coleus is actually a tropical perennial native to Southeast Asia, not a true annual, and can live for many years in warm climates or as a houseplant
🌱 Unlike most coleus varieties that require shade, chartreuse and yellow cultivars contain less anthocyanin pigment and can tolerate more sunlight—in fact, they need brighter light to develop their vivid chartreuse color
🌱 Coleus can be propagated so easily and quickly that a single cutting can become a full plant within 4-6 weeks, making it one of the fastest-growing ornamental foliage plants
