Plant of the Day

Monday 24 April 2023

Discovered in 1903 by Ernest Henry Wilson, Corydalis wilsonii grows in China on cliffs. It is a perennial of subalpine or subarctic habitats with an almost succulent-like blue-green foliage. It needs excellent air circulation and here was growing in a cool glasshouse.

When it comes to eye-catching garden design or standout houseplants, green is just the beginning. Plants with blue leaves offer a striking alternative, adding cool tones and silvery hues that instantly elevate any landscape or indoor jungle.

In this guide, we explore the science behind blue foliage, top varieties to grow, and how to use them effectively in your garden or home.

🌿 Why Are Some Leaves Blue?

Blue foliage in plants isn’t truly blue — it’s an optical illusion. The color results from waxy coatings, fine hairs, or light-reflecting surface structures that scatter light, creating a bluish or silvery appearance.

These adaptations often help:

Reflect intense sunlight

Reduce water loss

Survive in harsh, dry, or alpine environments
