Can I plant an Esperanza next to my redfoot tortoise?
Good searching.The Gulf Coast Turtle & Tortoise Society list the flowers as edible: http://www.gctts.org/WS/WS.php/Public/TurtleFriendlyPlantList
The Arizona Game and Fish Department lists it as a plant suitable for planting in desert tort enclosures: http://www.azgfd.gov/w_c/tortoise/documents/NativePlantsforDesertTortoises_2008.pdf
The Tortoise Group also lists it as a plant suitable for planting for tortoises: https://www.tortoisegroup.org/infosheets/infosheet21.pdf
Whether any of these sources are actually trust worthy though, I can't say.
ThanksOh, and a very warm welcome to Tortoise Forum.
