Angraecum Sesquipedale
Known as the "Star of Bethlehem Orchid" for its ivory-white, celestial shape, this Madagascan treasure is a legend in the world of biology. It is famously called "Darwin’s Orchid" because the naturalist famously predicted a long-tongued moth must exist to reach its deep nectar spur. Decades later, that very moth was discovered, proving this plant is a masterpiece of co-evolution.
The specific name sesquipedale is Latin for "one and a half feet," which refers to the incredible length of the nectar spur where the plant hides its sweet reward.

Growing Angraecum sesquipedale, also known as the Darwin's orchid or comet orchid, requires specific conditions to thrive. Here's a step-by-step guide on how to grow this unique plant:


To fertilize this plant, use a balanced, water-soluble fertilizer with an equal ratio of nitrogen, phosphorus, and potassium. Dilute the fertilizer to half of its recommended strength and apply it to the plant's soil once a month during the growing season (spring to fall). Water the plant immediately after fertilizing to help distribute the nutrients evenly. Reduce or stop fertilizing during the plant's dormant season (winter). Avoid overfertilizing, as this can cause root burn and damage the plant.
Angraecum Sesquipedale plant requires a special type of soil to thrive. The soil should be well-draining and have good aeration to prevent waterlogged roots. A mixture of coarse perlite, bark, and sphagnum moss is recommended for the substrate. The pH of the soil should be around 6.0-6.5. Additionally, the plant prefers humidity levels between 50-70%.
To propagate this plant, you will need to use a vegetative method such as stem cuttings or division of an established plant. Take a healthy stem cutting from the mother plant, making sure it has at least 2-3 nodes along its length. Dip the cut end of the stem in a rooting hormone powder and then plant it in a pot filled with well-draining soil mixture. Provide indirect light and warmth, misting the plant frequently to keep the soil moist. Within a few weeks, roots should begin to grow from the stem cutting and a new plant will emerge. If propagating through division, carefully separate the plant from its mother, making sure each new section has enough roots and foliage to sustain itself. Plant each new section in a pot with fresh soil and follow the same care instructions as for the stem cutting.
