The mulberry tree blossoms in March-April of the lunar calendar each year and bears fruit in May-June, and the ripe fruits are dark red, purple-black and white. The ripe fruits are not resistant to storage

. Mulberry, also known as mulberry fruit, also known as mulberry dates, mulberry fruit, mulberry seeds, etc., is a perennial woody plant mulberry

mature fruit spike.

The blackberry tree, or blackberry in general, is a widely distributed and well known shrub; plants belonging to the raspberry group (genus Cuspidata, family Rosaceae) can grow up to 3 m (10 ft) tall and produce soft fruits-often used in desserts, jams, seedless jellies, and sometimes to make fruit wines. There are several species of hoverberry called blackberries, and these species hybridize readily, so that the number of cultivated species can be much greater than that of the native species.

Blackberries have a creeping habit, with short, curved, but sharp spines on arching stems. When the curved, drooping branches touch the ground, roots will grow from the nodes at the top of the branches. This characteristic, combined with the rapid growth rate of blackberries, allows blackberries growing in woodlands, bushes, and hillsides to spread out and occupy a large area of land in a very short period of time. Blackberries can tolerate poor soil and are a pioneer plant for wasteland and construction sites. The leaves are palmate with three to five leaflets, the flowers are white or pink and bloom from May through August each year, and the fruit is black or dark purple when ripe.

In the blackberry, the flowers in the early stages produce more drupes than in the later stages, a sign of several possibilities: root depletion, an extremely low number of pollinators, or a small change in the state of the environment, such as a rainy day or a day too hot for the bees to work beyond the early hours of the morning, which results in fewer bee visits or fewer pollen grains being passed on to the flowers, and ultimately in a reduction in the quality of the fruits. The quality of the fruit is reduced. The drupe develops only in the vicinity of the ovule; the ovule is fertilized by male gametes from the pollen grains.

Blackberry flowers are a good source of nectar, and a large patch of wild blackberries can produce a brown to black, fruity honey.
