    Hi and good after-noon, can you please tell me if Nemesia are toxic to dogs or can they cause any skin irritation. MANY THANKS in advance.

      Hi, it’s neither particularly toxic nor irritating. For dogs it won’t be a threat. It’s only slightly discouraged to plant if you have rabbits, since it doesn’t make good fodder for rabbits.
