Rosa rugosa RAMANAS ROSES (10 seeds)

Ramanas Rose, beach rose also known as Japanese Rose or Rosa rugosa in Latin, is a slow-growing perennial shrub belonging to the Rosaceae family. It is a bushy species reaching heights of 1.5 to 2 meters and is native to Asia, specifically the coasts of China, Japan, Korea, and parts of Siberia. This plant is highly valued for its robustness and its ability to adapt to difficult conditions.

Its leaves are compound, consisting of 5 to 9 leaflets that are oval, serrated, and generally glossy. They are dark green and have a characteristic wrinkled or "rugose" texture, which gives the species its name. The leaves are arranged alternately along the stems.

The stems are sturdy and very thorny. They are usually straight and covered in sharp spines that help protect the plant from herbivores.

The flowers of Rosa rugosa are large, reaching up to 8 cm in diameter. They can be single or double and appear in various shades of pink. These flowers have a very pleasant fragrance that attracts many pollinators, especially bees. They typically bloom from late spring through summer, appearing in clusters of 2 to 5 flowers in the leaf axils.

The fruit is the rose hip, which develops after pollination. These fruits are rounded, measuring about 2 to 3 cm in length. they are bright red to orange and contain seeds.

Ramanas Rose seeds are yellow and angular. The internal downy hair of the fruit is an irritant, similar to "itching powder."
