Kohleria: Vibrant Tropical Flowers for Your Home

Botanical Name: Kohleria spp. and hybrids

If you're looking for a tropical plant that delivers non-stop color with minimal fuss, Kohleria is a top contender. These upright growers produce clusters of velvety, tubular flowers in rich crimson, pink, orange, and red — often with contrasting speckled throats. They're fast-growing, prolific bloomers, and surprisingly easy to please indoors.

Year-Round Care Essentials

Light: Bright but Filtered

Kohleria thrives in plenty of bright, indirect light. A south- or west-facing window with a sheer curtain is ideal. Direct sun can scorch the leaves, while too little light reduces flowering dramatically.

Water: Consistently Moist, Never Soggy

During the growing season (spring through fall), keep the soil evenly moist. Let the top inch dry slightly between waterings. In winter, cut back — water just enough to prevent the rhizomes from shriveling. Overwatering is the quickest way to lose this plant; the rhizomes rot easily in soggy soil.

Maximizing Blooms

The secret to heavy flowering? Light. Lots of bright, indirect light from spring through summer triggers wave after wave of blooms. Feed every two weeks with a high-phosphorus fertilizer (10-30-10) diluted by half during active growth.

Repotting: Pot-Bound Is Preferred

Kohleria actually blooms best when slightly root-bound. Repot only in spring when the plant has clearly outgrown its container. Always use a pot with drainage holes and a light, peat-based mix with added perlite — African violet mix works beautifully.

Quick Reference: Kohleria Care

• Origin: Colombia
• Height: 1–2 ft (30–60 cm); stake tall stems if needed
• Light: Bright indirect light; no direct sun
• Water: Keep evenly moist in growing season; barely moist in winter
• Humidity: Above 50% preferred. Use a humidity tray or room humidifier. Do not mist — hairy leaves trap moisture and invite botrytis.
• Temperature: 65–75°F (18–24°C); avoid temps below 60°F (16°C)
• Soil: Peat-based mix with perlite (African violet mix is ideal)
• Fertilizer: High-phosphorus liquid (10-30-10) every 2 weeks spring–summer, diluted by half
• Propagation: Divide rhizomes in spring, or root 4-inch leaf-tip cuttings under plastic in moist mix (4–6 weeks)
