What is Annatto?
Annatto (Bixa orellana) is a easy-care plant from the Bixaceae family. Bixa orellana, commonly known as annatto or the lipstick tree, is a fast-growing tropical shrub or small tree native to Brazil and tropical America. It is prized for its spiny reddish seed pods containing bixin-rich seeds, a natural orange-red pigment widely used as a food coloring and in cosmetics....
Annatto grows up to 8.0m, with spread of 400cm, watering every 7 days, 18°C – 35°C, 50–80% humidity. It is not suitable for indoor environments and safe for pets.
Care Guide
How to Water
Water every 7 days on average. Annatto is drought-tolerant and does not tolerate waterlogged soil. Allow the soil to dry slightly between waterings. During dry spells, water more frequently for better fruit production.
Lighting
Annatto requires full sun to grow and fruit well. Plant in a location with at least 6 hours of direct sunlight per day. Avoid shade as it significantly reduces fruit production.
Ideal Soil
Prefers well-drained, slightly acidic to neutral soil (pH 5.5–7.5). Tolerates various soil types but grows best in organic-rich soils. Add compost to the planting hole for best results.
Recommended Pot
Large outdoor planting preferred. If container-grown, use a large pot (minimum 50 liters) with adequate drainage holes.

It is prized for its spiny reddish seed pods containing bixin-rich seeds, a natural orange-red pigment widely used as a food coloring and in cosmetics. The plant produces beautiful pink flowers and is equally valued as an ornamental and as a commercial crop.
How to Propagate
Seed Propagation
Use fresh seeds for best germination rates. Keep substrate moist but not waterlogged.
- 1 Collect seeds from mature, dry fruit pods
- 2 Sow seeds 1-2 cm deep in moist, well-draining seed mix
- 3 Maintain in a warm location above 20°C
- 4 Transplant seedlings to their final location when 20-30 cm tall
Materials needed:
Hardwood Cuttings
Use clean, sharp tools. Remove lower leaves to reduce water loss.
- 1 Cut mature stem sections 20-25 cm long with a minimum 8 mm diameter
- 2 Apply rooting hormone to the base of the cutting
- 3 Plant in moist, well-draining substrate
- 4 Keep in a shaded, humid location until rooting occurs

Common Problems
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Cercospora Leaf Spot
Cercospora leaf spot is a common fungal disease caused by Cercospora species that affects many plant types, particularly beets, roses, and leafy vegetables. The disease thrives in warm, humid conditions and can cause significant defoliation, reducing plant vigor and yield. It spreads rapidly through water splash, wind, and contaminated tools.
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.
Meaning & Symbolism
Annatto has been a symbol of indigenous identity in the Amazon for over 3,000 years. The vivid red pigment from the seeds was used in body painting for rituals and ceremonies, representing protection and spiritual strength.
