Question: how can I choose roses and clematis to grow together?
at one point in the very sloping garden we have created a rocky boulder escarpment. I would like to cover it with a ground cover rose mixed with clematis. I am undecided whether to create two colors in harmony or in sharp contrast What does it say? and what types do you recommend? The exhibition is north
Roses on the slope: Answer: a flowerbed of roses and clematis
roses and clematis are often grown together, especially in the gardens of the United Kingdom, a little less in Italy, where the possible synergy between these two apparently different plants has not yet been well understood; different shapes, leaves, flowers and growth habit, but not due to cultivation requirements. Clematis and roses like fresh and loose, even clayey, fairly rich and well-drained soils; they love bright places, possibly sunny, or with at least a few hours of direct sunlight every day. In your case, being the slope facing north, I believe that your plot hardly enjoys much direct sunlight, but only diffused light; for this reason it is convenient that you plant those roses and those clematis that have a vigorous growth even in the shade or in partial shade, otherwise you will find yourself with few flowers (which is certainly not very appreciated by those who grow roses and clematis).
As for the clematis, I suggest you read this page
on the website of the International Clematis society, where they list the clematis that give great satisfaction even without a lot of direct sunshine. It is then up to you to choose the species and varieties you prefer.
As for roses, they too love direct sun, especially in spring when they begin flowering, and usually in completely shaded areas it is difficult to see them in bloom; therefore generally in the plots like yours you choose roses that have already shown to develop at best even in the shade; surely some of the most widespread ground cover roses, such as the iceberg, bloom everywhere, and have the advantage of not needing so much care during the year; the same applies to the “Ballerina” rose, a small rose with a light pinkish flower, pink Banksiae lutea, a creeping or climbing, with yellow flowers, often with little flowering; New Dawn, Cornelia, Felicia; on the net you can find various lists of roses that have a good development even in the shade or in partial shade.
As far as the combinations between the varieties are concerned, it depends a lot on your tastes, even if generally in preparing the flower beds you follow two different orientations, as you like; that is, you can prepare flower beds made of flowers all of the same shade, and therefore you could for example put clematis and roses with flowers in light pink shades. Or you choose the plants by contrast, and then for example prepare a flowerbed with white roses and blue clematis, so that the flowers of one stand out close to the flowers of the other, and vice versa.
In general, we tend not to approach an excessive number of colors, or if we decide to make a mixed flowerbed, with many varieties, we choose for example all pink, or in the various possible shades of pink; or by contrasts two very different colors are chosen, while a flowerbed with 3-4 or more contrasting colors becomes excessively heavy.
