Big Leaf Plants: 12 Outdoor Plants With Astonishingly Giant Leaves

Filling outdoor garden spaces with large-leaved plants eases the landscape with softened textures while developing architectural style with vibrant colors and dramatic shapes.

Luxurious Lushness

Giant leaves not only lusciously fill in garden space but also add luxurious tropical textures.

Low Light Equals Large Leaves

Growing extra-large leaves is an adaptation of some plant species to generate more surface area to absorb sunlight in low light conditions.

Similarly, growing giant leaves is thirsty work making large-leaved plants perfect for rain gardens, bogs, and borders of water features.

Foil With Foliage

Large leaves disrupt the scene, put things in perspective, make small spaces large, and rest the eye from busy views.

Planned Perfection

Incredibly useful, plants with giant leaves are not only excellent background plants but they also help break up the garden scenery of mixed smaller plants.

Super-Sized Leaves, Super-Fast Growth

Because their plant size and growth rate usually match their massive leaf status, give giant-leaved plants ample room to unfurl their sunshine collecting fronds.

3 Things to Consider with Giant-Leaved Plants

  1. Large leaved plants make for shady neighbors who might out shade and outgrow less gregarious plants.
  2. All that chlorophyl may attract some munching mouths including less desirable slugs and snails so consider protecting plants if needed.
  3. Giant leaves are easily damaged by wind and weather so consider providing protection or planting in sheltered areas in high-wind locations.
