These quick-blooming, quick-growing plants are simple to grow from seed and are excellent for temporarily adding colour to borders. Biennials grow in their first year, flower, and set seed in their second year, in contrast to annuals, which grow in their first year, flower, and set seed in their second year, before dying. There are many diverse varieties, including creeping or dwarf plants as well as climbers, tall-growing plants, and others. Numerous popular native wildflowers, including poppies, cornflowers, and foxgloves, are annuals or biennials.
The spectacular flowering of annuals and biennials frequently lasts from late spring to Autumn. Natural wildflowers give borders and containers an organic appearance, especially when planted among grasses, while more delicate varieties are frequently stronger in form and colour.
When most annuals and biennials have finished blooming, you can gather the seeds and plant the annuals in the spring and the biennials in the early summer.
The majority like a sunny location with light soil that warms up in the spring so they may get off to an early and swift start. In the beginning and during dry spells, they need regular watering. Hardy annuals and biennials will happily germinate outside, however half-hardy and sensitive plants require additional warmth.
Early in the spring, they must be sown inside in a warm environment; however, some varieties can be sown outside to flower in late May after the weather has warmed up sufficiently.
Even hardy varieties generally don't tolerate cold, damp soil, and the majority won't do well in shade. Young plants should be kept indoors until late May or early June before being planted outside.
