Perennial plants are long-lasting plants. They spend winter in the ground and grow each spring. Perennial plants are characterized by large variety. Among them you can
find species with a few centimeters in height as well as plants which are up to 2 meters. Perennial plants are mostly planted on bedding displays individually or in groups. They are great in rock
gardens, or among Calluna (heather) and Rhododendron.
Species that can be used instead of a law deserve special attention. They are cover species, such as Viola, Bergenia, Asarum, Astilbe, Aruncus, Galium or Alchemilla mollis.
Perennial plants should be preferably planted in spring, but we can always plant them between August and October, remembering that if we plant them late in autumn, we need to cover them for winter.
Flowers which shed blossoms should be removed. Thanks to that, perennial plants will bloom longer and the number of flowers will be larger. They may even bloom again. In particular this applies to species, such as Aquilegia, Salvia, Dianthus, Campanula, Hemerocallis, Echinacea, Achillea, Delphinium or Phlox.
It is worth noticing that not all perennial plants can survive winter in the ground in our climate. Low temperatures can kill them. It is worth noticing that despite being sensitive to frost, many species of perennial plants can be cultivated in gardens, if we remember to dig out the underground part of the plant and store it in a room protected against frost. Plants cultivates in such a way include Dahlia, Crocosmia, Galtonia, Gladiolus, Tigridia, Canna or Begonia.
Durable perennial plants, overwintering in the soil, include numerous species without which we cannot imagine our gardens.
Advantages of perennial plants
There is an opinion that one-year garden flowers are more vivid and blooming more abundantly than perennial plants. Even if this is the case, this is probably their only advantage - they grow quickly, they bloom abundantly, but next year we have to sow them again.
While perennial plants in comparison to one-year plants have numerous advantages and benefits:
- the most important one is that perennial plants grown in one place for many years and they do not require annual sowing renewal;
- most plants within the species bloom during the entire warm season from May to September, and some until the first frost;
- perennial plants are quit resistant to diseases, pests, drought and frosts - Iris, Narcissus, Galanthus
