Alder Catkin Free 3D Icon

A free isometric 3D alder catkin icon for botanical diagrams, seasonal nature content, plant education, and environmental design projects. Its detailed hanging flower form makes it useful for tree identification, ecology visuals, and spring-themed interfaces. Free to download and easy to use in presentations, apps, and websites.

Every Alder Catkin detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.

It suits tree identification, ecology visuals, spring-themed interfaces, botany and nature.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
