Its compact dimensions allow Clematis Tumaini to find a place in all gardens, and even on a simple terrace or balcony. It is easy to grow it permanently in a pot to create a charming scene alongside other small potted plants. You can associate it with a beautiful standard rose 'Leonardo da Vinci' with superb pink quartered flowers, pleasantly scented. Your Clematis will just as easily find a place in a shrub border, which can thus serve as its support. Foliage plants like Physocarpus will help you create interesting vegetation contrasts, as well as Cotinus, if you select smaller varieties.

A recent variety of Clematis, both compact and very floriferous. In spring, it produces an abundance of large purple flowers measuring up to 12 cm in diameter with a repeat blooming in September. This small climbing plant is easily grown in a pot or in a mixed border. It prefers fertile, moist but well-drained soils, preferably in full sun. It is deciduous and simply needs to be pruned back once a year in winter, to grow again even more vigorously in spring.

Description
Clematis Tumaini (EviGsy151) is a clematis with a climbing but compact habit, perfectly suited to small gardens, patios, balconies or terraces where it will be easy to keep in a pot. In spring, it offers two good months of abundant flowering, producing large star-shaped flowers of a beautiful light purple. This repeat-flowering, recent variety produces flowers again in September. Not exceeding 1.20 m in height, this attractive climber can be grown in a pot or in the garden in open ground. It is hardy and requires little maintenance.
Clematis are part of the Ranunculaceae family, which includes about sixty genera, many of which are ornamental, such as Hellebores and Buttercups. The Clematis genus includes no fewer than 300 species, mainly climbing ones, with a few exceptions, such as Clematis integrifolia, which behaves more like an erect perennial. The variety Tumaini comes from the species Clematis patens due to breeding work carried out by the breeder Raymond J. Evison, whose nursery is located on the Channel Island of Guernsey. It was named Tumaini in honour of a humanitarian fund primarily active with orphans in Tanzania.
This compact cultivar forms a clump 90 to 120 cm tall and 50 to 75 cm wide, which is perfectly suitable for growing in a pot or on a small trellis. The plant develops deciduous, deep, medium to dark green foliage, which highlights the flowering well. From late April, large star-shaped, 10 to 12 cm diameter flowers appear to bloom regularly in May and June. Most of the time, a repeat flowering occurs in September, slightly less abundant but just as attractive. The six sepals that make up the flower are elongated and pointed at their tips, and are coloured a beautiful light to medium purple. Each carries a central vein of a dark pink, further enhancing the starry appearance of the corolla. The centre of it is brightened by a bunch of pale yellow stamens with dark purple anthers. The numerous flowers will create a superb flowering pot when this Clematis is planted in a container. Its ornamental qualities have earned this cultivar a place on the shortlist of the Chelsea Plant of the Year (plant of the year of the Chelsea Flower Show, a world-renowned horticultural event organised by the highly respected RHS, Royal Horticultural Society of London). This semi-woody perennial Clematis is deciduous; its leaves fall in winter, when it should be pruned back to regrow the following spring.

Clematis: planting, pruning and care
Read article
Clematis is a climbing plant that has much to offer, but it also requires a certain level of attention. <strong>Its spectacular flowering makes it the queen of climbing plants</strong>, capable of transforming any space into a fairy-tale garden. The different varieties allow for staggered flowering, ensuring a colourful display almost all year round.
However, clematis has its requirements: <strong>it loves the sun but needs its roots to be in the shade</strong>. The soil must be <strong>well-drained</strong> while <strong>remaining cool</strong>, which may require mulching. It is also susceptible to certain diseases and parasites, so regular monitoring is advisable.
Pruning is another aspect not to be overlooked. <strong>Depending on the variety, it may require pruning just after flowering or at the end of spring</strong> for large-flowered varieties. Proper pruning will encourage a more abundant and healthier flowering.
Finally, let’s not forget that <strong>clematis needs a sturdy support for its</strong> <strong>voluble stems</strong>. Whether it’s a pergola, a fence, or even a tree, make sure to provide adequate support. For those short on space, the good news is that <strong>it can also be grown in pots</strong>, making it ideal for terraces and balconies.

Planting and care
Place Clematis Tumaini with its base in the shade and its head in the sun, to provide the best conditions for its growth and to encourage flowering. Keep the soil moist with a mulch applied in February. This should be formed of garden compost or well-rotted manure, avoiding contact with the stem. This will limit the risk of wilting and encourage new vigorous shoots from the base. You can also shade the base with a groundcover plant or a hardy geranium. Plant covering the root ball with 3 cm of soil, in soil worked to a depth of 20 cm, lightened with a good potting compost. The enemy of clematis is excess water, which is why you should water regularly, but sparingly, and not directly onto the base.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
