What are the plants that can not miss in the garden or on the balcony in 2018? The National Garden Bureau, an American association that promotes green culture, has chosen four of them every year: an annual, a perennial, a bulbous, an edible plant.
2018 will be the year of the tulip, of the calibrachoa (also called petunia nana), of the beetroot and of the coreopsis (on the organization's website, www.ngb.org, there are also advice on cultivation and curiosity).
The choice takes place every year taking into account different parameters: popularity, simplicity of cultivation, the ability of the plant to adapt to different environments, versatility.
