June glorious June! Everything outside is blossoming, blooming, and burgeoning with green vitality. Such a wonderful time of the year to be out, and here are 10 special plants for your June garden that are looking particularly fantastic at this time of year.
1. Cornus controversa (wedding cake tree) ‘Variegata’
This relatively slow-growing, easy to care for tree is astonishingly beautiful at this time of year when it produces clusters of pretty, white flowers. Its branches naturally grow out horizontally, making it a lovely focal point as well as a talking point for guests. Well-suited for small to medium sized gardens, it is sure to add something special.

2. Paeonia x lemoinei (peony) ‘High Noon’
The petals of this large, semi-double flowered variety are a gorgeous lemon yellow, revealing a very pretty circle of dark red stamens as the petals start to unfurl.

But, if necessary, it’s best to apply well-rotted manure before new shoots appear or alternatively a general purpose granular fertiliser.

Especially if you’re looking for plants for a pond edge, as these will grow in shallow water depths of up to 10cm as well as a wide range of conditions. This tall, elegant variety produces very beautiful soft, lilac-coloured flowers, held high above clumps of mid-green leaves.
