Erysimum, commonly known as wallflowers, can be either annuals, biennials or perennials, depending on the variety. This means that some types of Erysimum will come back each year, while others may only last for one or two seasons.
Annual wallflowers are those that complete their life cycle within one year. They are typically grown from seeds and will flower, set seed, and die within a single growing season. These types of wallflowers are often used as bedding plants or for adding temporary bursts of color to the garden. Once they have finished flowering and producing seeds, they will not come back the following year.
Biennial wallflowers, on the other hand, have a two-year life cycle. In their first year, they will grow vegetatively, producing leaves and a strong root system. Then, in their second year, they will flower and set seed before dying. Biennial wallflowers will typically come back each year, but only in the second year when they bloom. It is important to note that some biennial varieties may self-seed, allowing new plants to appear in subsequent years.
Perennial wallflowers are the ones that will reliably come back year after year. They have a longer lifespan and can continue to grow and flower for many years, given the right conditions. Perennial wallflowers often have a woody base and may form clumps or small shrubs. They are known for their ability to withstand colder temperatures and can be a great addition to a perennial border or rock garden.
In my personal experience, I have grown both annual and perennial wallflowers in my garden. The annual wallflowers provided a beautiful display of vibrant colors throughout the summer, but I had to replant them each year. On the other hand, the perennial wallflowers have been a reliable presence in my garden, coming back stronger and more colorful each spring.
If you are unsure about the specific type of wallflower you have, it is always a good idea to consult the plant tag or do some research to determine whether it is an annual, biennial, or perennial variety. This will help you understand its lifespan and plan accordingly for its care and maintenance.
While some Erysimum varieties may only last for a season or two, others will come back each year, providing you with a reliable source of beauty and fragrance in your garden.
