More About The Evergreen Clematis Armandii
The Clematis armandii or Armand Clematis species are beautiful vining plants with fragrant white flowers. The flower color with the evergreen leaves makes for a gorgeous spring and early summer backdrop.

Clematis Armandii Care Guide
So, now that you know the basics of the evergreen Clematis, where should you grow them? When planting this fast-growing vine, ensure that you space them a distance from the structure you want it to climb, like a trellis.
So, plant your vine at least 11 inches away to prevent the growth from stifling. Then dig a hole about 11 inches in diameter, pop your plant into it, and lean it slightly towards the structure or wall.
Alternatively, you can grow your Clematis armandii in a container instead of on the ground. Feel free to explore our article on Best Clematis Varieties To Grow, which offers a wide range of options for your Clematis-growing endeavors.
Suitable Soil For Armand Clematis
An important thing for the evergreen Clematis is well-drained soil that retains moisture. Hence, the soil needs to be humusy and rich in organic matter. In addition, it can tolerate neutral to somewhat alkaline soil.
The best time to transplant the Clematis species is in late fall to early spring before new growth appears. When grown in a container, ensure the soil drains well, and in both these cases, from a pot to the landscape, you can add a layer of mulch around the base to retain moisture.
The Best Lighting Needs For The Beautiful Fragrant Flowers
If you live in the USDA zones 7-9, the plants are pretty hardy and grow well in full sun. But these plants prefer having their head in a sunny location with their roots cool in the shade. As mentioned, add a layer of mulch or some flat stones at the plant’s base to provide partial shade on hot days.
If you live in arid climates, protect them from drying winds.
Watering Your Clematis Armandii
The plant’s watering needs are average. When it is hot, you can water your plant to help keep the soil moist. While the soil must not become waterlogged, leading to root rot, you must not let the soil dry completely between watering.
In winter, you will not need to water often as in the growing season.
Temperature and Humidity
As the evergreen Clematis falls into group 1, it does not need much protection from the winters and can tolerate temperatures down to 14°F. But it can still get damaged by frost and have occasional stem dieback.
If you are concerned about your flowering shrub, we recommend adding a layer of mulch to protect the roots from the cold. You can then, in late winter, remove deadwood as it will grow back.
Fertilizing Clematis
You can provide your evergreen Clematis with a balanced fertilizer in late fall or do this in early spring once new growth appears. We recommend staying away from a fertilizer high in nitrogen as it leads to vigorous growth instead of producing flowers. In autumn, we suggest enriching your woody vine with organic matter or compost for optimal growth and nourishment.
When you transplant your evergreen Clematis, you can once provide it with a 15-5-5 NPK fertilizer.
Pruning The Evergreen Clematis
The Clematis armandii falls into a pruning group that does not need any trimming. Still, they can overgrow their space, and a hard prune helps.
So, you can prune one side one year and the other year the opposite side. Then, when the bloom finishes, you can give it a prune and trim about 12 inches from the stem that flowered back.
Then remove the dead wood or pinch the stem to make the plant grow bushier. After it completes flowering, the reason for pruning is that the new blooms develop on the old wood of the previous year’s growth.
Propagation of Clematis
As the Clematis is an evergreen, it grows from the previous year’s wood and propagates through layering the semi or hardwood cuttings.
You can take cuttings in early spring for semi-hardwood cuttings. Or take some hardwood cuttings in late spring to summer.
Then plant them in well-drained soil in a sunny location living in a coastal climate or part shade in a hot climate.
