Non toxic plants - House LeekThe good parent versus the garden!

All parents want to keep their preschool children safe in the garden. There are so many hazards. Selecting the right kind of plants can be a daunting task, especially as so many common favourites are poisonous.

Don’t give up good gardening parents! There are plenty of friendly plants you can grow around play spaces.

List of the top 8 safe plants for the concerned parent: Very easy to grow child safe plants

The following is a selection of non-toxic plants. Please feel free to add other examples to the comments section. It’s also worth pointing out that even if it a plant is considered as non-toxic, eating large quantities of any non-food plant can result in a stomach upset. For this reason, keep an eye on small children and explain to them the importance of not eating from the garden.

Babies and Children with Pica and Autism

I recently received a request for a list of non-toxic plants. It came from a friend of mine who’s son has a rare disorder called pica. Pica results in an unnatural desire to eat non-nutritional substances such as soil, sand, grass and of course anything growing in the garden.

My eldest son, Samuel was diagnosed with autism at the age of three. Quite commonly for children with autism, he will readily eat anything if not supervised. A constant worry to us. To a large degree, this has shaped our own choices in what we plant in our own back garden.

Of course, this problem is not limited to the parents of children with pica or autism. Babies will happily see your back garden as a finger buffet. There are so many common garden plants that could cause sickness and even death if consumed.

Important advice

Although I have tried to research every plant on this list, this must still be taken as an “opinion”. Please thoroughly research each plant to ensure that toxicity levels are at an appropriate level for your children. Remember, eating any plant to excess, may result in undesired consequences. Try ‘Googling’: plant-name toxic humans.
