The hobby classic. Fast-growing, tolerates almost all parameters. Green in low light, orange-pink under high light. Variants: Ceylon (orange), Orange Juice, Colorata (pink). Ideal as beginner plant and volume filler in Dutch style.

Popular Vietnamese variety with narrow lanceolate leaves. Colours deep red-orange under high light and low nitrates. Part of R. rotundifolia species group but forms more intense colours.

Deepest red of all Rotala variants. The Singapore variant colours intense blood-red without extreme NO₃ limitation — a big advantage. Narrow leaves like H'ra. Grows upright and branches little; replanting after every trim is required for a dense bush.

Queen of red aquarium plants. Broad oval wavy leaves up to 50cm. 10+ variants: Red, Green, Narrow, Mini type 2 (rolled leaf margins), Mini type 4 (hardiest mini), Mini Butterfly (compact, deep pink-red), Variegated (white veins — rarest). Green variants are easiest; variegated and mini are hardest. Excellent indicator of tank quality.

Rare regional variant of R. macrandra. Slightly more compact than standard red with more branching. Same demanding care as regular macrandra — soft water and stable CO₂ are required.

Extremely rare R. macrandra variety with slightly different leaf shapes. Little documented in the hobby. Same demanding soft water requirements as other macrandra variants.

Most spectacular variant of R. macrandra: broad leaves with striking white leaf veins on deep red background. Harder to keep than regular red but the colour effect is unmatched. Requires KH <2°, high light and stable CO₂.

Compact orange-red Rotala with strong branching. Less temperamental than macrandra. Popular in Dutch style for mid-sized accent groups. Grows compact and holds its shape well with regular trimming.

Warm orange-yellow Rotala variety. More intense orange than Florida. Beautiful warm tint that contrasts excellently with cool red-purple neighbours in Dutch style. Same care as R. ramosior Florida.

Singapore variant of R. rotundifolia with exceptionally deep blood-red colour. Similar to Blood Red SG but separate selection. More intense colour formation than standard rotundifolia under same conditions. Rarer commercially available.

Unique needle-like leaves in whorls of up to 15 per node. Up to 45cm tall. Fine pink-red under high light. Grows submerged with virtually no branching — trim and replant necessary for volume. Sensitive to unstable CO₂.

Mexican variant of R. wallichii with slightly broader leaves and warmer orange-red colour. Similar care to standard wallichii but generally slightly more tolerant of harder water.

Oval bright green leaves that develop a subtle pink-red glow under high light. Branches naturally for dense bushes. Extremely sensitive to fluctuating parameters — stable low KH is the most critical factor. Rich soil with low water column dosing is the best strategy.

Variable species with multiple popular variants: Araguaia (light green-red, most popular), Goias (slightly darker), Belem. Characteristic brownish-red stems with narrow curved leaves. Not the easiest Rotala but more accessible than macrandra.

Rare Rotala from the Western Ghats of India. Red-brown colour with characteristic leaf pattern. Demanding — soft water and high light are required. Little documented in the hobby.

Compact Rotala with small leaves and reddish tint. Rare in trade. Requires stable soft water parameters. Less documented than other Rotala species but grows similar to wallichii.

Permanently green R. rotundifolia that never turns red regardless of conditions. Fast-growing and robust. Lowest requirements of all Rotalas. Excellent as green contrast next to red variants. Suitable low-tech.
