WaterThe Ethiopian Acanthus should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. A good rule of thumb is to water every week during active growing seasons such as spring and summer, tapering off to every two weeks or as needed during cooler weather. When watering, aim to provide about 1 to 1.5 gallons per plant depending on the size and the container it's in. It's important to avoid waterlogging, as this can lead to root rot. Ensure the plant has proper drainage in place.
LightThe Ethiopian Acanthus thrives best in full sun to partial shade. For optimal growth, place it in a spot where it will receive at least six hours of sunlight daily. If you're growing the plant indoors, a south-facing window is ideal. However, in extremely hot climates, some afternoon shade can help prevent scorching of the leaves.
TemperatureThe Ethiopian Acanthus prefers a relatively warm climate and does not tolerate extreme cold well. It can endure temperatures down to about 25 degrees Fahrenheit, but frost may damage the foliage. For ideal growing conditions, maintain an ambient temperature between 60 and 75 degrees Fahrenheit. Make sure to protect the plant from freezing temperatures by moving it indoors or providing insulation if it's planted outside.
PruningPrune the Ethiopian Acanthus to maintain shape and health. Deadheading spent flowers encourages further blooming. Pruning should be done in late winter or early spring before the new growth starts. Cut back the foliage to ground level if it's damaged by frost or to refresh the plant annually. This also helps promote vigorous growth and a more abundant bloom in the following season.
CleaningAs needed
SoilThe Ethiopian Acanthus prefers a well-draining soil mix with a pH between 6.0 and 7.5. A mixture of loamy garden soil, peat or coco coir, and perlite or sand aids in appropriate drainage and aeration. Regularly test soil pH and adjust accordingly to maintain the ideal range for healthy growth.
RepottingEthiopian Acanthus should be repotted every two to three years, or when it outgrows its current pot. Choose a container that is one size larger than the previous one to provide enough space for root growth. Best done in the spring or early summer.
Humidity & MistingEthiopian Acanthus thrives in an environment with average humidity. While it can tolerate some drought, it does best in humidity levels of 40-60%, common in many indoor settings without the need for additional humidity control.
Suitable locationsIndoor
Place Ethiopian Acanthus in bright, indirect light and maintain room temp.
Outdoor
Plant in partial shade, shelter from strong winds, enrich soil, water as needed.

Life cycleAcanthus sennii, commonly known as Ethiopian Acanthus, begins its life cycle as a seed, which germinates in warm, moist soil. Upon sprouting, the seedling develops a rosette of spiny, glossy green leaves. As a perennial, it then enters a vegetative growth phase, maturing and forming a robust clump with tall flowering stalks. The flowers are reddish-orange and bloom in the summer, attracting pollinators such as bees. After pollination, the flowers produce seed capsules which, when mature, release seeds to start a new generation. In the right conditions, the Ethiopian Acanthus may also propagate vegetatively through root division.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method for propagating Acanthus sennii, commonly known as Ethiopian Acanthus, is by seed. Sowing can be done in late winter to early spring, once the risk of frost has passed. The seeds should be sown in a well-draining soil mix, about a quarter inch (6 mm) deep, and kept moist until germination, which typically takes a few weeks. It's important to provide warmth and light, but not direct sunlight, which can scorch the seedlings. Once the seedlings have developed a few true leaves, they can be transplanted into individual pots and later transferred outside when they are strong enough to withstand outdoor conditions.
