Nice list, thanks! I have a dog, so the indoor plants I have are nontoxic: an african violet, a nontoxic fern, culinary herbs in hubby's Aerogarden, and a goldfish plant (which I love!! It is so cool looking.) Used to have a Persian violet which was fabulous and fragrant-- smelled great for about 2 months, but it eventually finished flowering, sickened and died. It was replaced by the goldfish plant.

The toxic plant list helps me pick plants for outside, cuz the bunnies cant/wont/betternotiftheynotwhatsgoodforthem eat it. :) D

The numbered plants are those that somebody on the Butterfly Gardening forum has used to SUCCESSFULLY rear caterpillars to adulthood or has actually observed the caterpillar eating. If there is no numbered plant, then nobody on our forum can vouch for any specific plant. If a butterfly in the list below has no numbered plant, research the plant family shown for hostplant candidates. Several forum members report that using nursery or home-improvement store plants can be poisonous to caterpillars and adult butterflies due to pesticides or other chemicals. You have three main options: 1--raise the plant from seed (best). 2--prune the plant, do not put it in a prominent location, and wait for some new growth before presenting the plant to butterflies (good). 3--buy nursery/store plants, wash them thoroughly (fair; it is hard to get all the chemical off of the plant).

The list below are plants that have all been found growing and thriving in the wild of the most coldest gardening regions. Many have hybrids that have been bred from them...these hybrids generally will be able to also grow in the same plant zones and survive the same long and bitter winters. Please do research them if you're unsure of their hardiness in your particular zone or region, and as always, with any seeds that you're unsure can be Winter Sown in your region save some seeds to start indoors.
