Otaheite Gooseberry (Phyllanthus acidus)
The Otaheitie Gooseberry, or ‘Grosella’ as it is commonly called, is a deciduous tropical to subtropical fruiting tree thought to be native to Madagascar. Part of the Euphorbiaceae family, it is related to the rubber tree, cassava, and castor-oil plant. Unlike its other gooseberry namesakes, the Grosella bears a rather sour-acidic flavor signature which separates it from the rest.
Grown as a shrub or tree, the Grosella grows dense crowns of canopies covered in alternating ovate, pointed leaves. The medium-speed growing foliage sports smooth tops and blooming undersides attached to rough branches. These mucilaginous leaves can be crushed and used as a poultice on sciatica, lumbago and rheumatisms.
When flowering, blossoms burst open with pink-to-red cross-shaped clusters. Waxy inch-long Grosella fruits ripen in colors ranging from pale-yellow to creamy-white and ripen into ribbed fruits bearing juicy, acidic flesh. In their stone center, Grosella fruits house 4 to 6 seeds, used medicinally for cathartic properties.
Slice away the stone and prepare the fruit by sugaring and setting it aside for a day to balance acidity. Alternatively, cook the flesh and press the fruits to separate the stones and use the flesh for chutney, juice, preserves or candy. When cooked in sugar, the Grosella turns to a ruby-red jelly. In India, they believe the fruit enriches the blood and is often taken as a liver tonic. Learn your favorite use for the unique Grosella!

Growing Guide for Amla (Indian Gooseberry)
Climate and Soil Requirements
- Climate: Amla thrives in warm, tropical to subtropical climates and is best suited for USDA hardiness zones 9-11. It is drought-tolerant once established and can withstand high temperatures, making it well-suited to hot, dry regions.
- Soil: The tree prefers well-draining, sandy, or loamy soils but can tolerate a variety of soil types, including slightly alkaline or saline soils. It thrives in soil with a neutral to slightly acidic pH (6.0-7.0).
Planting
- Location: Choose a sunny spot that receives at least 6-8 hours of sunlight daily. Full sun is necessary for optimal fruiting and growth.
- Soil Preparation: Loosen the soil and mix in organic compost to improve fertility and drainage.
- Planting Time: Plant in spring or early summer when temperatures are warm and frost danger has passed.
- Spacing: Space trees 15-20 feet apart to allow for their broad, spreading canopy.
Watering
- Moderate Moisture: Water regularly, especially during the first few years of growth, to help establish a strong root system. Once established, Amla is drought-tolerant and only needs occasional watering during dry periods.
Sunlight and Fertilizing
- Full Sun: Ensure the tree receives at least 6-8 hours of direct sunlight per day for optimal growth and fruit production.
- Fertilizing: Apply a balanced, slow-release fertilizer in early spring to support healthy growth and fruit development. Organic compost or manure can also be applied to improve soil fertility.
Pruning and Maintenance
- Moderate Maintenance: Amla requires occasional pruning to remove dead or damaged branches and maintain its shape. Prune in late winter or early spring before new growth begins. Thinning out dense branches can help improve air circulation and sunlight penetration, leading to better fruit production.
- Drought Tolerance: Once established, Amla is highly drought-tolerant and thrives with minimal care, making it a low-maintenance addition to gardens.
Pest and Disease Management
- Common Pests: Amla may attract pests like aphids, scale insects, or caterpillars. Use insecticidal soap or neem oil to manage infestations.
- Diseases: The tree is generally disease-resistant but may suffer from root rot if grown in poorly draining soil. Ensure good drainage and avoid overwatering to prevent fungal issues.
Harvesting Amla Fruits
When to Harvest:
- Amla fruits are typically ready to harvest in late fall to winter when they turn a light greenish-yellow and become firm to the touch. The fruits should be picked when fully mature, as this is when they contain the highest nutrient content.
How to Use:
- Amla can be eaten fresh, though its tart flavor may be intense for some. The fruit is often dried and ground into powder for use in teas, supplements, and Ayurvedic remedies. Amla can also be made into jams, pickles, chutneys, or juices to enjoy its health benefits.
