One solution to enrich your garden, creating lush bushes and flowering borders, can be to grow perennials.

Perennial herbaceous plants sprout spontaneously every spring, eliminating the expense and labor of buying back annual plants each year.

Perennial herbaceous plants have an average life of about 7 years, thus offering flowering periods that, depending on the species, can be extended for all months of the year.

Moreover, they are easy to cultivate and have little need for watering, and for this reason they are also useful in more difficult garden areas, such as rocky gardens, dry or particularly humid areas.

They can also colour balconies and terraces, cultivated in pots or crates.
