Source: leafsnapEuphorbia stygiana (Portuguese: Trovisco-macho) is a species of evergreen shrub in the family Euphorbiaceae, endemic to several islands of the Azores. It has a critically endangered subspecies (subsp. santamariae) with only 20 known remaining mature individuals in the wild.
Care Guide
💧 Water
Euphorbia stygiana needs regular watering, roughly once a week, during its growing season. Make sure to water the plant when the top 2 inches of soil have dried out. Even indoor plants need some moisture during their resting season. To avoid over-saturation, it's best to water from below.
☀️ Light Partial sun
Euphorbia stygiana comes from habitats with dappled light, such as forest understories or rocky sites that provide natural shade. It prefers partial sunlight but can also tolerate full sun.
🌡️ Temperature 20–37.8°C
Euphorbia stygiana grows best in warm conditions and needs relatively high temperatures during the growing season to support growth and metabolic activity. It prefers abundant sunlight, proper moisture levels, and good air circulation. It can be harmed by very low temperatures and by excessive watering. Similarly, maintaining balance is important—extremely high heat and overly dry conditions should also be avoided.

🌱 Fertilizer
For Euphorbia stygiana, small amounts of fertilizer once or twice a year during the growing season are enough. Do not fertilize in winter or during summer dormancy. Use less fertilizer for plants that have been repotted and wait a couple of months after repotting before you start feeding. Fertilizing helps maintain healthy growth and promotes flowering.

✂️ Pruning
Euphorbia stygiana is an evergreen shrub characterized by its thick stems and small leaves. To keep it healthy, prune it in early spring by removing any dead stems and thinning out crowded areas to improve air circulation. Light, regular trimming not only maintains the shrub’s shape and prevents it from becoming overgrown, but also enhances its flowering and overall health.
