This breed of clematis is a beautiful vining plant with early blooms that bring about a great deal of fragrance and being evergreen they are extremely popular.

It can reach between 2 and 5m in height, requires partial sun or full sun, deep and cool soil, and with all of that in play, it will provide beautiful flowers as early as March. This particular variety is perfectly well suited to container growing and will quickly make its way up any lattice work or walls that you have.

Once you have planted your clematis and allowed it to properly settle, it requires very little care thereafter. Because they bloom early in the year, you can prune relatively early as well but it only really needs pruning to control the size or remove dead or damaged stems. Young plants should be pruned back to around 30cm after the first spring to encourage the plant to produce more shoots low down. Word of warning, established plants don’t usually respond well when hard pruning established plants.

When to prune

As with any plant you want to prune after the blooming cycle has finished. Pruning the clematis is designed to increase the foliage density and improve flowering for the upcoming season. The more it is pruned, the more flowers you will get. To that end, you want to perform your pruning in March or April depending on when it blooms as it should be pruned as soon as it has finished flowering.

How to prune

The thing to note is that they don’t need pruning like clematis in group 1 and 2, they only need pruning to control the size. In order to prune you want to get the sharpest shears you have. The sharper they are the less likely it is that you will have to make multiple cuts which are beneficial for the plant because each cut you make leaves a cut which leaves it susceptible to infection just the same way as a cut on your body would leave you susceptible to infection.

When you are ready, first cut back the stems which have already produced flowers. You want to cut them back to a good framework. If you want to cut back any branches that are dead or dying, and very weak stems. These should be cut back completely. Pruning established plants should take place more often than brand new plants. In fact, you don’t really want to prune for the first few seasons after the first season, you want to allow the roots ample time to establish themselves. After that, you can take advantage of pruning established plants regularly in an effort to keep the blooms and the flowers potent, fragrant and to control the size.

Overall caring for the clematis armandii is quite simple. you can plant it in the springtime and let it bask in the sunlight in the ground or in pots after which you can simply prune it regularly and lightly, to encourage better growth and sit back, relax, and take in the air leafage with the early blooms that produce small and vanilla-like white flowers.
