Marigold

Russian Tortoise

Agrionemys horsfieldii

ReptiFiles explicitly lists daisy and other edible flowers in the Russian Tortoise safe plant list; Calendula officinalis is widely recognized as an edible flower analogous to daisy and is recommended by Tortoise Trust. High-fiber, low-protein flower suitable for daily inclusion.

Leopard Tortoise

Stigmochelys pardalis

Tortoise Trust recommends Calendula officinalis as safe; Leopard Tortoises are grass-heavy grazers but edible flowers are acceptable supplements. No known toxicity and no goitrogenic properties identified.

Eastern Box Turtle

Terrapene carolina

Tortoise Trust endorses Calendula officinalis as safe, and Eastern Box Turtles as omnivores consume a wide range of plant matter including flowers. No toxicity mechanism identified; flowers provide dietary variety within the 50% plant component.

Hermann's Tortoise

Testudo hermanni

Tortoise Trust recommends Calendula officinalis as safe for Mediterranean tortoises, and keeper consensus supports it as a good variety flower. No known antinutrients or toxicity mechanisms identified for Hermann's Tortoise.

Red-eared Slider

Trachemys scripta elegans

ReptiFiles lists dandelion flowers as safe for Red-eared Sliders; Calendula is similarly an edible non-toxic flower and Tortoise Trust endorses it as safe. Aquatic turtles are primarily protein and leafy-green feeders, so flowers are supplementary.

Greek Tortoise

Testudo graeca

Tortoise Trust recommends Calendula officinalis as safe; Greek Tortoises (T. graeca) are Mediterranean herbivores that commonly graze edible flowers in the wild. No goitrogenic or oxalic acid concerns identified for this species.

Yellow-bellied Slider

Trachemys scripta scripta

Yellow-bellied Sliders share a dietary pattern with Red-eared Sliders; Calendula is non-toxic per Tortoise Trust and comparable edible flowers (dandelion) are listed as safe by ReptiFiles for sliders. Use as dietary enrichment within the vegetable component.

Sulcata Tortoise

Centrochelys sulcata

ReptiFiles lists daisy and petunia as safe for Sulcata, and Tortoise Trust endorses Calendula as safe; flowers are not a primary dietary component for grass-heavy Sulcata but can be offered as enrichment. No fruit classification applies; this is a flower with no sugar concern.

Painted Turtle

Chrysemys picta

Tortoise Trust notes aquatic plants and salad are freely available for painted turtles; Calendula is a non-toxic edible flower endorsed by Tortoise Trust as safe. Adults shift to more plant matter and can benefit from flower variety.

Red-footed Tortoise

Chelonoidis carbonarius

Tortoise Trust endorses Calendula as safe, and Red-footed Tortoises as omnivores readily consume a wide variety of plant matter including flowers. No toxicity mechanisms identified; edible flowers contribute dietary variety.
