About this tool
L-System Plant Generator is a free online visual effect. Input rule string to generate fern/tree fractal patterns. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
When opening the page, it will show that a plant grows from the seed, continues to branch and grow leaves, forming a complex fractal structure. The form of a plant is generated by a simple set of rules (L-system syntax), and each time it is run produces a different plant form.
The whole process is pure front-end animation. Based on Canvas's L-system algorithm, string rules are converted into turtle drawing commands to draw the branch structure of plants. You can customize rules, iteration times, colors, etc.
Suitable for generating art displays, botany science popularization, or purely appreciating the natural beauty of fractal plants. The implementation principle is the combination of formal language theory and turtle drawing.
L-system is a fractal plant generation special effect based on the Linden-Mayer system that simulates the recursive branch structure of plant growth.
