Clematis atragene I am Red Robin

Clematis I am Red Robin is a recent cultivar. It produces small campanulate flowers, with closed raspberry-red bell-shaped petals and a cream interior. It blooms early and for a long time. This moderate-sized climber thrives on old walls, trellises, fences, and even in trees. Its numerous tendrils mean it can climb anywhere. It is perfect when combined with a bush, in a container, or on a fence.

Clematis is a genus in the Ranunculaceae family. It includes around 30 species of herbaceous perennials with woody roots and climbing plants, which are semi-woody, evergreen, or deciduous. They are found in both hemispheres, particularly in Europe, the Himalayas, China, Australia, North and Central America. Clematis I am Red Robin is a recent cultivar, derived from C. alpina and C. koreana (Clematis Tetragene section). It belongs to Group 1 (early-flowering clematis) of the clematis groups, which is composed of 3 divisions. It is a semi-woody, climbing perennial plant that reaches a height of 1.5 to 2m (5 to 7ft), with a spread of 1m (3ft). Groups are defined based on cultivation requirements.

This clematis bears small, narrow campanulate flowers, 5cm (2in) in diameter. They bloom on the previous year's growth from April onwards if the weather is mild. The bisexual flowers are solitary or grouped in clusters. They have no petals but have 4 tepals. The flowering is followed by decorative, silvery-grey feathery fruits. The leaves are sometimes opposite, sometimes alternate. They are glabrous and have simple, ternate, irregularly toothed edges. This clematis attaches itself to supports or host plants through petioles transformed into tendrils.

The name "clematis" comes from the Greek "klema", which means "vine stem", as its old stems have a woody and twisted appearance with cork exfoliations.
