Aniseed Myrtle
Aniseed Myrtle (Backhousia anisata) is an evergreen shrub with a naturally upright habit. Its smooth, glossy leaves are fragrant and highly variable, from round-edged fans to more jagged and split shapes. Its yellow flowers, appearing between late autumn and early spring, are small, sitting amid clouds of white stamens to create a stunning display. B. anisata is often used as an edible accent plant for kitchens and other spaces, contributing a unique flavor to dishes.
Aniseed Myrtle is quite drought tolerant and does not require large amounts of water. It tolerates short dry spells very well, though during the Summer the soil should remain moderately moist. During the driest periods, lightly mist the leaves to keep them from drying out.
Aniseed Myrtle grows best in a location with partial to full sun, though it can manage in dappled shade too. It prefers a well-draining soil with some general fertiliser in order to thrive, though it is not overly specific as to soil type. If grown in an area with full sun exposure, it is best to give it some light afternoon shade.
Aniseed Myrtle prefers temperate climates with cool winters and warm summers. It is hardy to USDA zones 8-11, thriving in temperatures between 45-85°F (7-30°C). It prefers protection from extreme temperatures and hot winds, and can suffer frost damage if temperatures fall below 25°F (-4°C).
Aniseed Myrtle is not overly fussy about humidity levels, but does prefer humid conditions. If grown in an area with lower levels of humidity, misting the leaves over long dry periods can help increase the level of moisture in the air around the plant and help it thrive.
Aniseed Myrtle grows best in a soil that is well-draining with a slightly acidic pH. The soil should contain some general fertiliser and be moderately rich, though it is not overly specific as to soil type. The potting soil should be allowed to partially dry out between waterings to avoid root rot.
Aniseed Myrtle responds well to regular fertilization. Use a diluted, balanced liquid fertilizer every two weeks during the active growing season. For best results, water the plant and apply the fertilizer in one sitting and avoid fertilizing during the Winter months.
Aniseed Myrtle is affected by aphids, scales, mealybugs and spider mites. The best way of controlling these pests is to spray the leaves of the plant with soapy water. The soap acts as a deterrent and disrupts the pest's reproductive cycle, ultimately killing them. If the pest outbreak is serious, pesticide sprays or systemic insecticides may be necessary.
Aniseed Myrtle can be repotted every two to three years to avoid becoming pot bound. It is best to do this in the Spring before the active growing season begins. When repotting choose a slightly larger container, with fresh potting soil and water well once done.
Aniseed Myrtle can be pruned at any time of the year to maintain its shape and size. Prune away any dead or dying wood and remove any crossing branches to help light and airflow circulate through the plant. Pinching back young shoots can also help stimulate bushier, fuller growth.
Aniseed Myrtle benefits from the addition of organic mulch such as shredded bark or compost. This helps conserve moisture in the soil, reduce temperatures, and add additional nutrients as the mulch breaks down over time.
Aniseed Myrtle can be easily propagated from both stem and root cuttings. For stem cuttings, take a 4-6 inch piece and remove the lower leaves. Dip in a rooting hormone and insert into a damp, soilless medium. For root cuttings, take a 3-4 inch piece and cut into 1-inch sections. Dip in a rooting hormone and insert into a damp, soilless medium. Keep the cuttings in a place with indirect light and the soil remains evenly moist.
Aniseed Myrtle is a naturally upright shrub which does not require additional support. If the shrub has grown lanky or is affected by wind, loosely tying the main branches to a bamboo support can help strengthen the structure of the plant.
Aniseed Myrtle does not have a heavy dormancy period, but during the Winter months it does best in a spot away from cold drafts and temperatures below 25°F (-4°C). Water only when the soil becomes dry to the touch and stop fertilizing in late Autumn.
Aniseed Myrtle is not toxic to pets, making it a great choice for those looking to add a fragrant shrub to their houseplant collection without having to worry about their furry friends.
