This is a lovely spring combination, Aquilegia 'Swan-Lavender' with Euonymus fortunei Emerald Gold and Rhododendron luteum. This planting combination creates a bright yellow splash in the border and these plants are easy to grow.
Aquilegia, common name columbine, is a herbaceous spring perennial with delicate flowers. The true beauty of the Aquilegia is not really displayed in the image, check out growing Aquilegia. Euonymus is a common garden shrub which means it can get overlooked but many varieties have strong variegated leaves. It is evergreen and fully hardy.
The Rhododendron in this planting combination is deciduous but has the real bonus of being scented. In common with all Rhododendrons it needs acid soil to thrive.
