(= Alpine atragene (L.) Mili.)
Atragene of the Alps
Climbing plant 1 - 2 m long, poisonous. Leaves twice tripartite. Flowers with 4 large, violet or bluish tepals. Flower. : VI - VII. It grows in the mountains in sparse woods and in bushes.
Cultivation and use in the garden
This plant has very similar needs to those of other clematis.

It wants a very deep, moist and fresh substrate. It prefers slightly calcareous soils. It must be planted by digging a hole at least 40 cm deep. On the bottom you will have to prepare a good draining layer with gravel or expanded clay. Laterally, in the direction of the radical bread, it is advisable to place a small hollow cane in which we will slide the water. In this way, even in the presence of very compact and not very permeable soil, we will be sure of being able to get the liquid to even the deepest hypogean part.Exhibition and garden setting

The ideal exposure for these plants is undoubtedly the shadow or at most the partial shade. Let us remember that these are typical climbers of the undergrowth. They love to grow under large trees, possibly also deciduous. They will benefit by behaving as they would in their natural environment, ie using the branches as a support to go upwards. We should not fear for our tree: the clematis alpina does not have such a force to cause damage and bring it to decline. Always put them at a certain distance so that they make a short path to the ground and then begin to cling to the trunk. Moreover, there will not be excessive radical competition.
In shady areas they can also be used easily as a ground cover. They are very beautiful in combination with brunnere, hydrangeas and hostas.


In the absence of rainfall the irrigations must be abundant, from spring to autumn. Initially they will support flowering, then they will help the development of new branches that will bring flowers in the following year.


To stimulate flowering it is good, from the end of winter to spring, to mix irrigation water with a good fertilizer for flowering plants characterized by a high content of phosphorus and potassium. After flowering, instead, it is good to stimulate vegetative growth, favoring the presence of nitrogen.


Pruning is not strictly necessary. On plants like this, which bloom on old branches, if you are not sure of your intervention it is better to give up or get help from an expert person. Generally speaking, after the end of flowering, the branches that brought the flowers into the vintage are popped up, thus stimulating the thickening. On the other hand, the new branches produced from that moment on must not be touched.
Damaged or dead stems can be eliminated.

Pests and adversities

These are very healthy plants and are rarely affected by parasites.

Clematis alpina: Variety

The clematis alpina and the Siberian variety, which is botanically close to her, have been domesticated due to their ornamental value: hybrids have been created with Clematis macropetala and ochotensis, thus reaching a wider range of colors.
In the blue we find Frances Rivis, Pamela Jackman, Blue Bird, Cecil, Lagoon. In pink are available instead: Pink Flamingo, Willy, Ballet Skirt, Jacqueline du Prй, Pointy.
Belle also the mauve (Betina, Constance, Ruby), purple (Brunette, Purple spider) and white (albina plena, White Snow) cultivars.
