Wonderberry Sunberry Seeds (Solanum burbankii) are a unique annual berry developed as a cross from the huckleberry, but with a much sweeter flavor and larger size (up to 1/2" in diameter). This berry plant is easy to grow, and can be cultivated in rows just like tomatoes, once all frosts have passed. The berries ripen early on even small plants (as short as 6"), but they require patience to fully ripen. Green berries are slightly poisonous, so they should only be harvested when they turn black and lose their shininess. While raw wonderberries have little flavor, they develop a rich taste when cooked, making them perfect for pies, jams, and jellies.
The Wonderberry, or Sunberry, is a hybrid plant developed by renowned plant breeder Luther Burbank in the early 20th century. This cross between Solanum villosum and Solanum guineense closely resembles the wild garden huckleberry, but the flavor is much sweeter and superior. While the name “garden huckleberry” is sometimes used interchangeably with wonderberry, the flavor of wonderberry is far more desirable. These plants thrive in a variety of growing conditions and can be enjoyed both in the garden and in culinary creations.
Hardiness: The wonderberry is not frost-hardy and must be grown as an annual. It is suitable for all USDA zones and Sunset Zones.
Size: Wonderberry plants are small, typically growing to 12-24" in height, but they can start producing fruit as small as 3-4".
Sowing Time: Sow Wonderberry Seeds all year round, but they are best planted outdoors after the danger of frost has passed. You can also start them indoors in early spring.
Sowing Depth: The seeds need light to germinate, so simply sprinkle them on the surface of the substrate and gently press them down. 🌱
Sowing Mix: Use a mix of coir or general sowing mix combined with sand or perlite to improve drainage.
Germination Temperature: For optimal germination, keep the temperature between 20-25°C (68-77°F).
Location: Plant in a bright, sunny location. Keep the soil moist (not soggy) to encourage healthy growth. 🌞
Germination Time: Germination can take anywhere from 1-8 weeks, depending on the growing conditions. ⏳
Watering: Keep the soil consistently moist throughout the growing season. Water regularly, but avoid waterlogging the soil. 💧
Fertilization: Wonderberries do not require heavy feeding. However, you can apply a light balanced fertilizer to encourage strong growth and fruiting. 🌿
Sunlight: These plants thrive in full sun or partial shade. They are flexible and will grow well in a sunny window or outdoors. 🌞
Pruning: Pruning is generally not necessary, but you may want to remove dead or damaged stems as needed.
When to Harvest: The berries are ready for harvest when they turn black and become non-shiny. Never pick them while they are still green, as they are slightly poisonous.
How to Harvest: Gently pick the berries once ripe. Be careful not to damage the plant while harvesting.
Wonderberries are perfect for use in cooking, especially in sweet dishes. Once the berries are cooked, their flavor develops into something far superior to raw huckleberries. The most common uses include:
Pies: Add wonderberries to pies for a unique and sweet twist. 🥧
Jams & Jellies: They make an excellent base for homemade jams and jellies. 🍇
Desserts: Wonderberries are great for flavoring desserts, turning ordinary treats into something extraordinary. 🍰
