Jean-Francois Schwob from the Turcieflor nursery presents to us in this video, the various varieties of agapanthus allowing a cultivation of these plants with exotic connotation in almost all regions of our country. He also details the growing conditions that will make it possible to obtain the splendid flowering that has made the success of this plant.
Multiple species and varieties
Agapanthus is a plant with pure green foliage forming a rounded tuft and producing beautiful blue or white flower stalks, sometimes even pink or pastel mauve, or even two-tone depending on the cultivar.
She is synonymous with exoticismthe Côte d’Azur, the island of Bréhat, in short, regions with a mild climate.
You say to yourself that this plant will be complicated to cultivate in Orléans or Paris, in regions where frost is rife and where the climate is not clement, but think again because there is such diversity among these plants that some will be usable in the majority of gardens, despite sometimes complicated conditions.
Origins of the agapanthus
The agapanthus is from South Africawhere its many varieties grow in various areas with varying climatic conditions.
L’species the best known and the most common in garden centres, is called Agapanthus africanus. This spectacular plant presents a dense evergreen and of large blue or white flowers.
However, there are other species present in South Africa and neighboring countries, such asAgapanthus campanulatus, A. praecoxor A. inapertus.
This grande variety cashthis genetic diversity, has allowed the creation of many hybrids of different sizes, different heights, of various colors, but above all deciduous varieties with much better resistance to cold.
Different hardiness zones
In nature, the various species of agapanthus do not all originate from the same geographical areas; Agapanthus africanus grows on the coast in mild regions, while deciduous species naturally grow higher in areas where cold and frost are more present. In these regions, there are also long periods of drought forcing these plants to come to vegetative rest. Their rhizomes in the ground will give them a very good resistance to cold thanks in particular to the disappearance of their aerial parts in cold weather.
At the end of winter, the deciduous agapanthus will produce new shoots which will then come out of the ground, we can also note that at the base of these shoots, we will find colored aspects, a little darker on certain species like the one in our video.
Our classic evergreen agapanthus (A.africanus) has a cold hardiness of the order from -5 to -10°Cif well established, while a deciduous variety like ‘Northern Star‘, well known to gardeners, will tolerate temperatures from -15 to -18°C. This therefore makes it possible to grow an agapanthus in the garden even in a relatively cool region where the temperature will drop to -10°C during the coldest periods.
In all cases, however, it is necessary to plant agapanthus in a sunny area with a draining soil which will not retain water for too long in winter so as not to accentuate the effect of the cold on the root system (the hardiness decreases in moist soil) or cause risk of rot.
There are two types of agapanthus beyond the sizes, shapes and colors: varieties with foliage persistent which are generally very beautiful and very well known, and recently, the deciduous varieties, finally available on the market, which will allow you to have beautiful agapanthus almost everywhere in France both in the garden and in pots.
When you go to a garden center or a specialized nursery to acquire your agapanthus in early spring, you will therefore find different types of products.
On one side, the beautiful, highly developed tufts of agapanthus africanusas in our example ‘Queen Mum‘ a well-known two-tone variety and tested in the garden.
On the other hand, deciduous varieties will have much less foliage at this time of year, ie in early spring, because the leaves are just starting to grow back.
In store, you will therefore find yourself in front of a smaller and less attractive plant in terms of foliage, however this should not hinder you in your choice, because the plant is just waiting to grow. You will then have access to fabulous varieties such as ‘Glacier Stream‘ whose immaculate white flowers are tinged with pink at their ends, or ‘Graphite White‘ displaying beautiful white flowers carried by black stems offering a wonderful contrast.
At the end of winter, these plants have very little vegetation, however they are just waiting to grow to express their full potential during the summer when they are well established in your garden.
