Top Picks for December Gardening: Suggestions from Leading Horticulturists
Bringing Colour and Structure to Winter Gardens
As the days grow shorter and temperatures drop, many gardens may seem to lose their vibrancy. However, there are a number of plants that can bring colour and structure to a garden in December.
Pansies, thriving in cooler temperatures (40°F to 60°F) and ideally suited for winter colour, are a great choice for partial sun or shade. Their bright blooms add a splash of colour to the garden during these colder months.
Dahlias can last until December in milder climates, provided temperatures stay above 35°F. These plants, originating from Mexico and South America, bring rich colours to the garden with their vibrant blooms.
Asters are hardy perennials that bloom in vivid blues, pinks, and other colours, lasting into late fall and December. They are known for their hardiness and versatility.
Hellebores, also known as Christmas roses, are evergreen perennials that flower in late winter and early spring. They offer a range of colours from white to black shades, adding structure and winter interest especially in shaded gardens.
Christmas cactus is a popular houseplant, known for its bright flowers during dark winter days, symbolising hope and renewal.
In addition to flowers, winter vegetables like kale, spinach, and carrots add structure and greenery to a garden in December, focusing more on foliage than flowers.
For shade gardens specifically, hellebores are especially recommended for winter flowering and structural interest with their evergreen foliage.
