King Charles III will be crowned on 6th May 2023. The coronation ceremony will take place in Westminster Abbey and be conducted by the Archbishop of Canterbury.

Across the UK, people will be hosting garden parties and picnics and making festive spring tipples to mark the occasion (see our favourite Coronation party decorations and outdoor tableware if you're hosting). To get ahead of the game and start prepping your garden, why not plant some of these celebratory plants in honour of His Majesty the King.

Clematis 'Prince Charles'

To celebrate King Charles III's ascension to the throne, you could plant Clematis 'Prince Charles.' Producing mauve-blue flowers in summer and early autumn, this climber is perfect for scrambling over walls and trellises and adding a pop of colour and height to the garden. It is a compact variety making it great for growing in containers too, which could be paired with a small obelisk. Plant this clematis in sun to part-shade, preferably with the roots shaded. Take a look at our guide on pruning clematis too for extra guidance on caring for this plant.

Achillea 'Coronation Gold'

Achillea 'Coronation Gold' would be a fitting tribute to grow in the garden to honour King Charles. Apparently introduced to honour the coronation of Queen Elizabeth II, it features tall stems with clusters of bright yellow flowers that are very popular with bees. Yarrow works especially well planted with grasses and in prairie-style planting schemes.
