Arbutus unedo STRAWBERRY TREE (7 seeds)

Strawberry Tree, madrone also known as Arbutus unedo, is a shrub from the Ericaceae family. It is a hardy, slow-growing perennial shrub that reaches about 2 meters in height. Native to the western Mediterranean basin, it is particularly noted for its distinctive red bark.

Its fruits, which turn from yellow to red depending on their ripeness, are called arbutus berries (or cane apples). They are sweet, round in shape with a rough skin covered in small conical points, making them look like strawberries.

The leaves are evergreen, thick, glossy green, and oval-shaped.

Strawberry Tree seeds from the Arbutus unedo are dark brown, flat, thin, slightly curved, and measure about 2 millimeters in length.

Its flowers are white, bell-shaped, and hang in clusters. they are scentless and bloom from August to September.

- Uses:

The strawberry tree is mainly appreciated for its culinary uses and the processing of its fruits. Although the flesh of the arbutus berry is mealy in its raw state, it is perfectly suited for making jams, jellies, and syrups.

In some Mediterranean regions, the fruit is also fermented to produce artisanal liqueurs and vinegar, thus offering a sweet and slightly tangy flavor.

In cosmetics, strawberry tree extracts are integrated into skincare products to promote complexion radiance and tighten pores thanks to their astringent qualities.

Finally, the strawberry tree fulfills essential functions in crafts and landscaping. Its wood, hard and dense, is an excellent fuel and remains prized in marquetry or for the manufacture of small turned objects.

On an ecological level, this shrub is widely used for reforestation and ornamentation, as it resists pollution and drought well while offering aesthetic evergreen foliage that protects soils against erosion.

- Sowing and Germination:

• The most favorable time to sow the madrone is during March and April.
• Stratify the seeds either naturally by leaving them outside during the beginning of the year, or artificially by placing them in the refrigerator for 2 months.
• Sow in small 10 cm pots using a substrate based on potting soil and sand.
• Lightly cover the seeds with a few millimeters of soil.
• Water the planting gently with a sprayer.
• Place the culture in a greenhouse at a temperature of 25 to 35°C.
• Germination will generally begin within 4 to 6 weeks after sowing.

- Soil and Substrate:

It grows in a draining, light, and slightly acidic substrate. The soil should be sandy and mineral-rich. For pot cultivation, mix garden soil with heather honey (terre de bruyère), and remember to drain the bottom of the pot with clay pebbles.

- Exposure and Light:

It should be planted in full sun in a very bright location. It also tolerates partial shade, although fruit production will be less abundant.

- Temperature and Hardiness:

It grows very well in temperatures ranging from 15 to 35°C. It is quite hardy and can easily withstand negative temperatures reaching -12°C in a dry environment. Its USDA hardiness zone is 7b.

- Watering and Irrigation:

This Mediterranean shrub is very drought-resistant; it does not require much watering except during the initial planting phase. Water the plant twice a week during the first three weeks.

- Propagation:

The simplest way to propagate it is by seed or by layering its stems. However, rooting is slow; it takes several months before the first roots appear.

- Pests and Diseases:

Overall, it is not very susceptible to diseases and pests. However, it can sometimes contract septoria leaf spot, a fungal disease, if the soil is poorly drained or waterlogged.
