As autumn deepens and winter approaches, ornamental brassicas take their moment in the garden. Known commonly as flowering cabbages or kales, these striking plants hold their colour when most flowers have faded. Their rosettes of crinkled leaves in shades of purple, cream, and green seem to intensify as the temperature drops. In fact, a touch of frost makes them look even more vibrant, as if crowned with a layer of sparkle. For UK gardens, they are one of the most reliable choices for lasting colour through the colder months.
The Beauty of Brassicas
Ornamental brassicas are grown for their foliage rather than flowers. Their rounded heads form tight clusters that resemble cabbages, but with leaves painted in soft creams, deep violets, and rose tones. These colours only deepen as nights grow colder. Unlike many plants that retreat in winter, brassicas thrive in cool weather and hold their beauty well into January. This makes them a favourite for gardeners looking to extend seasonal interest.
Why Brassicas Deserve a Place in Your Garden
Brassicas offer qualities that set them apart as a winter essential:
They provide reliable colour in late autumn and winter when few other plants remain attractive.
Their cold tolerance makes them well suited to UK conditions.
They are low maintenance, requiring little more than good soil and regular watering in dry spells.
Their bold foliage adds structure and texture to borders, containers, and beds.
While ornamental brassicas are not designed as a nectar source for pollinators, their presence in the garden keeps structure and colour alive, which supports the wider ecosystem by ensuring the garden remains active and appealing during the quietest months.
Planting and Care
Brassicas are easy to grow if planted with care:
Position: choose sunny or lightly shaded areas for best colour.
Soil: fertile, well-drained soil is essential. Adding organic matter before planting improves vigour.
Watering: keep soil moist but avoid waterlogging, especially in containers.
Spacing: give each plant room to form its full rosette shape.
Maintenance: remove any yellowing leaves at the base to keep plants fresh and tidy.
Brassicas grow well in borders where their colour contrasts with evergreen shrubs or grasses. They also thrive in pots and containers, making them ideal for patios and entrances where they can be enjoyed up close.
Brassicas in UK Gardens
In UK gardens, ornamental brassicas are valued for their resilience. They tolerate damp weather, frosts, and shorter days with ease, often improving in appearance as temperatures fall. Gardeners across the UK use them to keep displays bright long after summer bedding is cleared. Grouped in containers, paired with winter pansies, or set in formal beds, they provide a bold, decorative touch that lasts through the darkest months.
A Crown of Colour for the Cold Season
Brassica – Cabbages Crowned with Frost is not only a name but a description of what they bring to the garden. When frost dusts their leaves, they shine as a symbol of resilience and beauty in the face of winter. Available at Netplant, these ornamental cabbages are an easy way to ensure UK gardens remain colourful and inviting when the rest of the garden has fallen quiet.
