What is your question for a Master Gardener?
Hi, I have a question about Moon Flowers. I have heard that their family member Trumpet Flowers are poisonous and I am wondering about the Moon Flowers. I have the bush variety growing in my garden and our son, who lives in Florida, wants some of the seeds to plant there. Do you know if they are an invasive plant in Florida? I don’t want to take him any seed pods if they are. They are a beautiful flower! Thank you
Your son is in luck. Moonflower (Ipomoea alba) is native to subtropical regions of North and South America; that includes Florida. It is actually related to Morning Glory and can also be known as Tropical White Morning Glory. The only mention I can find of toxicity is that the plant has historically been used to produce rubber from the latex in its plant material. If you have a latex allergy, then it might be a plant to avoid.
If you are giving your son seed you have saved from your Moonflower, be sure to tell him to nick the outer coating of the seed with a file and then soak the seed overnight before planting. There are some species of plants that require this preparation in order to properly germinate. If he is using seeds from a nursery, the puncturing of the seed coating is usually done prior to packaging. It’s best to read the package instructions prior to planting.
I hope that answers your question. Thank you for submitting the question.
