Is this a flower illustration generator?

No. It creates botanical floral diagrams, which are schematic top-view plans of flower structure. It is meant for floral formulae, plant morphology, and botany education, not realistic flower art.

Does the floral diagram generator use AI credits?

No. The tool runs in the browser, parses the formula, and renders SVG locally. It does not call an image model or LLM.

What does K4 C4 A2+4 G(2) mean?

K4 means four sepals, C4 means four petals, A2+4 means six stamens in two groups, and G(2) means a fused two-carpel gynoecium.

What do parentheses mean in a floral formula?

Parentheses usually indicate fusion or cohesion of parts in that whorl. This tool marks fused whorls with a fusion ring so the diagram remains easy to read.

Can I use P instead of K and C?

Yes. Use P for perianth or tepals when sepals and petals are not clearly separated, such as in many monocot examples.

Can I download the generated floral diagram?

Yes. The current diagram and each example can be downloaded as SVG or PNG. You can also export a CSV table of the parsed whorls.

G: 2 fused gynoecium / carpels

Floral Diagram Examples

Compare common floral formula patterns and download each diagram.

Brassicaceae Formula

K4 C4 A2+4 G(2)

A mustard-family style diagram with four sepals, four petals, and six stamens.

Fused Corolla Example

K(5) C(5) A5 G(2)

Shows fusion rings for the calyx, corolla, and central carpels.

Tepal Flower Example

P3+3 A3+3 G(3)

Uses perianth tepals instead of separate sepals and petals.

Many Stamens Example

K5 C5 A∞ G(5)

Caps a many-stamen formula into a readable schematic ring.

What is a floral diagram generator?

A floral diagram generator turns a floral formula into a schematic top-view drawing of a flower. Instead of drawing a realistic blossom, it maps sepals, petals or tepals, stamens, and carpels into botanical whorls so students can see the structure behind a formula.

Why this tool parses formulas instead of using image AI

Floral diagrams are notation diagrams, so part count, whorl order, grouping, fusion, mother axis, and bract placement need to stay predictable.
The tool reads common formula patterns such as K4 C4 A2+4 G(2), K(5) C(5) A5 G(2), and P3+3 A3+3 G(3).
It renders SVG directly in the browser, so the same formula always produces the same diagram and does not use image-generation credits.
SVG, PNG, and CSV export make the result reusable in botany worksheets, lab notes, slides, and study guides.

Supported notation

K for calyx or sepals, C for corolla or petals, and P for perianth or tepals.
A for androecium or stamens, and G for gynoecium or carpels.
Numbers set part counts, plus signs create grouped whorls, and parentheses mark fused parts.
The infinity symbol or the word many is capped into a readable schematic ring.

Floral diagram vs floral formula

A floral formula is compact text notation. A floral diagram is the visual plan that shows how the organs are arranged around the flower. Use both together when teaching flower morphology, comparing plant families, or checking whether a student can translate symbolic notation into a diagram.

How to make a floral diagram from a formula

Enter a formula using K, C, P, A, and G notation.
Choose whether to show labels, the mother axis and bract, and fusion rings.
Check the parsed structure list to confirm counts and fusion.
Download the final floral diagram as SVG or PNG, or export the parsed whorl table as CSV.
