Centrochelys sulcata

ReptiFiles explicitly lists geranium as safe for Sulcata Tortoises. Suits the high-fiber herbivore diet; no sugar, protein, or toxicity concerns identified.

Russian Tortoise

Agrionemys horsfieldii

ReptiFiles explicitly lists geranium (Pelargonium × hortorum) as safe for Russian Tortoises. No toxicity concerns identified in available sources; suits the high-fiber, low-protein dietary profile.

Greek Tortoise

Testudo graeca

No toxicity mechanism identified in any source; keeper consensus supports geranium as safe for Mediterranean tortoises including Greek (Testudo graeca). Tortoise Trust notes this species is particularly vulnerable to goitrogens, but geranium carries no known goitrogenic risk.

Leopard Tortoise

Stigmochelys pardalis

No toxicity identified; ReptiFiles confirms safety for Sulcata, a species with nearly identical dietary requirements to Leopard Tortoise. Tortoise Trust warns Leopard Tortoises are goitrogen-sensitive, but geranium has no known goitrogenic properties.

Eastern Box Turtle

Terrapene carolina

ReptiFiles supports varied plant foods for Eastern Box Turtles; geranium has no identified toxicity mechanism and is compatible with the plant component (~50%) of this omnivore's diet. No explicit listing exists for this species but no contraindications are found.

Hermann's Tortoise

Testudo hermanni

While The Tortoise Table does not specifically list geranium, ReptiFiles confirms safety for closely related tortoise species with similar dietary needs. Keeper consensus also supports safety for Mediterranean tortoises.

Yellow-bellied Slider

Trachemys scripta scripta

Yellow-bellied Sliders share the same dietary pattern as Red-eared Sliders per ReptiFiles; geranium has no identified toxicity and is appropriate as an occasional plant food within the vegetable component of the diet.

Painted Turtle

Chrysemys picta

Tortoise Trust notes aquatic plants and salad greens are appropriate for Painted Turtles; geranium carries no identified toxicity and is suitable as an occasional plant addition for adults whose diet shifts toward more plant material.

Red-eared Slider

Trachemys scripta elegans

ReptiFiles lists dandelion and hibiscus as safe vegetable options for Red-eared Sliders; geranium carries no identified toxicity and fits within the plant-matter component. No explicit listing for this species, but no contraindications identified.

Red-footed Tortoise

Chelonoidis carbonarius

No toxicity mechanism identified in any source for geranium; keeper consensus supports its use for Red-footed Tortoises. Compatible with the omnivorous diet's leafy green component (approx. 60% of intake).
