General description

General description: The Niobe clematis was created by Władysław Noll and was awarded the Award of Garden Merit in 1993. Due to its compact growth, it’s excellent for growing in plant containers, so it can become a beautiful embellishment of any balcony or terrace. It grows moderately fast, reaching around 2.5 m in height.


Flowers: The Niobe variety exhibits large, velvety flowers around 14 cm in diameter, composed of 6 elongated petals. They are dark crimson in colour, almost black at the start of blooming. Stamens have yellow anthers on white filaments.


Blooming: The Niobe clematis blooms profusely in June and repeats flowering at the turn of August and September, although in a less abundant flush.


Leaves: This variety has green, simple or trifoliate leaves composed of oval, almost elliptical leaflets.


Cultivation requirements: The Niobe clematis likes sheltered but sunny spots and grows well under any exposure (N, S, E or W). For optimal growth, it needs moist soil rich in humus, with a neutral or slightly acidic pH. The substrate must be breathable (heavy, compacted clays are not suitable but sandy soils are also not advised).


Care: In autumn it is worth covering the base of the plant either with compost or decomposed, old or granulated manure, and in spring applying a mineral fertilizer is recommended. Regular generous watering is needed during the growth season (unless heavy rainfall occurs).


Pruning: The Niobe shrub should be pruned lightly. At the turn of February and March, dead or damaged stems should be removed, and healthy ones only lightly trimmed – a year after planting just above healthy buds to around 30 cm above ground; in the second year, some 70 cm above ground, and in later years it should be cut to a height of around 1.5 m. Trimming a young clematis plant should not be feared – such pruning forces outward growth right from the base, and as a result the shrub looks denser in later years.


Props: This variety easily grows on all kinds of nets, poles, hung ropes, grates and trellises, fences, pergolas and arbours. The elements of support should not exceed 1 cm in diameter.


Overwintering: This clematis is frost resistant (in hardiness zone 4, withstanding -34°C). Protecting young seedlings for the winter is recommended, for e.g., by piling a mound of soil or peat about 30 cm in height over the plant. This clematis is a deciduous shrub.
