L-System Plant Art Studio

A free, multi-language, offline, L-System Plant Generator app. Grow nature with math.

L-System Plant Generator turns simple grammar rules into stunning procedural plants, trees, ferns, and fractals — the same technique used by botanists, animation studios, and game designers to generate organic life.

Start from a curated preset, tap Randomize for instant inspiration, or write your own production rules. Tweak iterations, branching angle, stem color, leaves, and watch your plant grow in real time.

Features

- 17+ classical L-system presets — Sapling, Branch, Fern, Pine, Oak, Willow, Sakura, plus mathematical fractals (Koch, Sierpinski, Dragon curve, Hilbert curve, Snowflake)
- Full color control — background, stem, leaves, with light & dark themes
- Realistic leaves — oriented leaf shapes at branch tips, with adjustable size
- Randomize button — endless one-tap inspiration
- Live preview — every change rendered instantly
- Custom rules editor — write your own grammars (one rule per line, e.g. F=FF+[+F-F])
- Save & revisit — keep up to 60 plants locally
- Share & export — share as PNG to any app
- Light & dark mode — automatic or manual

PRO unlocks

- Premium presets — Fern, Oak, Sakura, Dragon, Hilbert and more
- Gradient stems — depth-based color blending from trunk to tip
- Stochastic mode — organic randomness for natural-looking plants
- Growth animation — watch your plant grow segment by segment
- 4K PNG export — print-quality 4096×4096 renders
- SVG export — infinite-resolution vector files for design work

About L-systems

Invented by biologist Aristid Lindenmayer in 1968 to model plant cell division, L-systems are recursive string-rewriting grammars. A simple seed like F plus a rule like F → FF+[+F-F-F]-[-F+F+F] expands into trees of breathtaking complexity. Five symbols are all you need — F (forward), + (turn right), - (turn left), [ (push state), ] (pop state) — and the math draws the rest.

Whether you're a designer hunting for organic textures, a teacher exploring fractals with students, a developer prototyping foliage, or just someone who loves watching algorithms paint nature — this app is for you.
