The 'Opal' Plum is a variety of fairly strong vigour, productive and regular. It produces small round plums, slightly oval, purple-red on a yellow background. Their flesh is juicy and tasty. The harvest of this early variety starts at the end of July and continues into August. The 'Opal' Plum is self-fertile and proves to be a very good pollinator. It is resistant to diseases.
The original area of plum trees is said to be Syria, not China. During the time of Roman hegemony in the region, various local fruits including plums were introduced to Rome. The 'Opal' Plum is a variety selected in Sweden in 1925, in Alnarp. It is the result of cross-breeding: 'Early Favourite' x 'Reine-Claude d'Oullins'.
This fruit tree naturally grows up to 5m (16ft) tall at maturity. The upright silhouette given by its habit is appreciated, and, when pruned properly, it will be easy to harvest. It enjoys the sun or partial shade, sheltered from the wind, and grows in any type of rich, moist, deep, and even heavy soil, but without limestone.
Its leaves are ovate, almost oblong, serrated-dentate, and slightly pubescent.
Flowering occurs in late April. The tree is then completely covered in white flowers that appear on the previous year's shoots. They are self-fertile. This variety is perfect for pollinating many other plum trees.
It produces small round plums, slightly oval, purple-red on a yellow background. Their flesh is juicy and tasty.
The plums are consumed raw at the foot of the tree, in fruit salads, but also in desserts, pastries, as an accompaniment to meat and dishes. They can be transformed into jams, of course, but also into preserved fruits, compotes... They can also be used to make eau-de-vie.

Botanical data
Easy to grow, the 'Opal' Plum Tree thrives in any type of light, rich, neutral or acidic soil, as long as it is moist but not overly wet and without limestone. Ensure proper drainage by adding a layer of gravel to the planting hole. Dig a hole two to three weeks before planting, twice as wide and deep as the pot. On the day of planting, place the tree with its pot in a basin of water to moisten the entire root ball through capillary action. Add compost to the bottom of the hole. Place the tree in the hole and fill with a mixture of soil and compost. Do not bury the graft union. Firmly tamp down the soil around the base. The root ball should be completely covered. Water generously. You can add a small handful of wood ash, rich in potash, during the winter to improve fruiting.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
