I would like to make a container with Canna Cannova (orange), Lobelia (laguna sky blue) and Fiber Optic Grass for our front porch. We have a one yesr old grandson that we take care of 2 days/week. Are any parts of any of these 3 plants harmful/poisonous if he touches them or ingests them?

Welcome from the Pacific NW, hope you enjoy this site. I can't speak to the toxicity of your plants other than to suggest you search 'canna toxicity' etc. to see what you find out. Another approach might be to plant things that are actually OK to eat - lettuce, nasturtium, strawberries, etc. No worries that way and there are some beautiful edibles. I always encouraged my kids and grandchild to walk around with me and pointed out which plants to sample (I have a large herb garden) and which ones to stay away from.

The tuber of the canna canova is used to make food in Thailand, so probably not toxic. http://www.cannova.info/uk/con...

Lobelia is thought to be a toxic herb - taken in large quantities. http://medherb.com/Materia_Med...

Fiber optic grass is definitely toxic to cats, and is reported at DG to be toxic in all its parts.

I agree with Deb. Plant the canna with some redbor kale and strawberries, or make it all edible from the getgo. What color is the canna? This could get interesting.
