Broom (Genista)

Broom, also widely known as Genista, is a group of shrubs characterised by their slender stems and distinctive yellow flowers, which light up the landscape. These shrubs enrich Danish natural areas and gardens and can thrive in different conditions. 

Broom thrives best in well-drained soil with a neutral to acidic pH value. They are often tough plants that can cope well in poorer or stony soil types. Good drainage is important to avoid waterlogging, which can damage the roots. Broom shrubs are also known to be resistant to dry conditions and can do well in areas with low rainfall.

When it comes to light conditions, broom is a sun-loving plant. It thrives best in areas with full sun and needs at least six hours of direct sunlight a day for optimal growth and abundant flowering. This makes broom well suited to positions along garden edges, on slopes or in open natural areas.

Broom shrubs are not only a delight to the eye with their colourful flowers – they also contribute to biodiversity by attracting pollinators such as bees and butterflies. Their robustness and adaptability make them suitable for many different areas in Denmark
