Thanks for that, the Valerian I am after is called Red Valerian or more properly Centranthus ruber. If anyone can advise I'd be most grateful as I don't want to damage the littel chaps, they are only about 16 weeks at present, and very hungry!
Red Valerian.... best to avoid.... used alot in sleeping medicine effect not known on tortoises... i could do with some though lol... some do feed it on the odd occassion without any bad effects.... but its said its not readily taken.... and i'm not sure i would risk it
