Description
An umbrella shaped shrub or small tree to 10 in height, originally native to forests from western tropical Africa to Tanzania and northern Angola to 1000 m elevation, but widely cultivated elsewhere. It has pointed leaves with undulated margins and perfumed, white flowers followed by small red to black fruits. The infusion made from the roasted seeds of Coffea canephora, also known as Robusta coffee, is the second most popular and most consumed type of coffee in the world (after C. arabica) and is often used in blends and instant coffee. It grows well in many tropical areas.

Moderate
Coffea canephora, commonly called Robusta coffee, is a hardy species native to the tropical forests of Central and Western Africa. It is valued for its disease resistance, high caffeine content, and ability to thrive in warm, humid conditions where Arabica cannot. Seeds are recalcitrant and must be sown fresh, requiring consistently warm temperatures and high moisture for successful germination.

Additional notes
Use fresh seeds within 2 months of harvest; older seeds take longer to germinate and lose viability; remove papery seed coat to reduce mold and improve germination speed
Substrate & Container
Recommended substrate
Well-drained, rich organic matter mix; peat moss, perlite, and sand mixture recommended
Recommended container
Individual cells or cups after radicle emergence; cover with humidity dome during germination
Growing Tips
Keep seeds fresh and moist; germination is slow and erratic, typically 42-56 days. Remove parchment coating before sowing to reduce mold and speed germination. Maintain high humidity with clear plastic covering and daily misting. Ensure soil never dries completely. Cover seeds with moist sphagnum moss to maintain moisture contact. Watch for seed rot by maintaining proper air circulation. Once leaves appear, seedlings are easy to grow.
