The base of the leaf stalks (petioles) is greatly expanded. Smyrnium olusatrum, common name alexanders (or alisander) is an edible flowering plant of the family Apiaceae (Umbelliferae), which grows on waste ground and in hedges around the Mediterranean and Atlantic coastal regions of Europe.
The plant's flowers are yellow and grow up to an inch in diameter, with five petals attached at the base. Flowers grow on stalks and can either be found in clusters or individually where the stalk meets the leaf stem. [4] Pod-like capsules produced by the plant consist of 12-15 wood segments that form cup-like rings.
Datura innoxia is quite similar to D. metel, to the point of being confused with it in early scientific literature. D. metel is a closely related plant, believed until recently to be of Old World provenance (though now thought to have been brought to Asia from the Antilles no earlier than the sixteenth century) and misconstrued as being referred to in the works of Avicenna in eleventh century ...
The plant itself remains a ground cover for the duration of its life (45–60 cm), forming massive bushes rather quickly. The aroma of the plant has been said to resemble cannabis or skunk . [ 3 ] [ 4 ] They bloom twice a year, in late summer and in late winter.
Cannabaceae are often dioecious (distinct male and female plants). The flowers are actinomorphic (radially symmetrical) and not showy, as these plants are pollinated by the wind. As an adaptation to this kind of pollination, the calyx and corolla are radically reduced to only vestigial remnants found as an adherent perianth coating the seed. A ...
Apocynum cannabinum grows up to 1 m (3 ft 3 in) tall. The stems are reddish and contain a milky latex.The leaves are opposite, simple, broad, and lanceolate, 7–15 cm (2 + 3 ⁄ 4 –6 in) long and 3–5 cm (1 + 1 ⁄ 4 –2 in) broad, entire, and smooth on top with white hairs on the underside.
Like many climbing plants, star jasmine is fairly easy to propagate. You can create new cuttings to expand your garden in just two steps: Take 4- to 6-inch cuttings from healthy, established ...
They are mostly spread by the wind, but can also cling to fur, clothes and machinery, enabling long-distance dispersal. Seed production is about 80,000 to 90,000 per plant. Seeds need light to germinate. The plant can regenerate from the roots. In favorable conditions the plant can grow more than 3 cm per day. [11]
