💡 The biannual or biennial flowers

Focus on biannual flowers

Annual flowers are sown in the winter or spring of year 1 and bloom in the same year, in late spring or summer.

Biennial flowers require more patience as they have a life cycle spanning two calendar years: sown in the summer of year 1, they develop a rosette of leaves in fall, but do not flower until the spring of year 2.

The advantage of biennials is that many will bloom early in the spring, unlike annuals, which will bloom later.

Some of the best known biannual flowers are: forget-me-nots, wallflowers, hollyhocks, pansies, daisies, primroses, lady’s julienne, pennyroyal, foxgloves, poet’s carnations …

To know: some biannuals are replanted alone in the garden, such as forget-me-not, foxglove, julienne, pennyroyal …

      • Get your own seeds biennially, in your own garden or in a friend garden.
      • Place the harvested seeds in small paper bags, in which you will be careful to write the name of the flower and the date of harvest.
      • Store these bags in a closed metal box, to place it in a dry place.

    • Plant your biennials indoors in trays, just like any indoor seedbed.
    • When the plants are strong (4-5 weeks), transplant them into small containers.
    • Keep your buckets until fall in a sunny but sheltered place.

3 Plant the biennial

    • Place biannuals in fall of year 1, for example: forget-me-nots, daisies, pansies …
    • Exception: place the yellow alelíErysimum cheiri) only in early spring of year 2, after having winterized them in pots located in a temperate place (greenhouse, garage).
    • Install the biannual plants in full, well-loose soil, respecting the planting distances.
