Any nectar plant that has white blooms will be a big boost for your nighttime moth garden. Datura is much used in my garden. It may not be hardy in your zone, but you can grow it from seed each year. Same with brugmansias, nicotiana, petunias (white), white cypress vine, and an especially good vine is Moon Vine (Ipomeae alba). Your 4 o'clocks are a good plant for moths, too.

Check out Select Seeds for their nighttime gardening plants. You don't have to order from them, but they will give you some suggestions.

Here's to your successful night blooming garden!

I was going to suggest Select Seeds--they have specific collections for "Moon Gardens."

Have fun!

Petunias often attract sphinx moths.

Many smaller moths that do not visit flowers like to roost on flat vertical surfaces, even if the surface is lighted. They can be easily observed close up. That is not a plant suggestion, but it could be incorporated into your garden area.

Thank you so much for the suggestions, I do have petunia seed and I just received my select seeds catalog the other day. I'd never seen white cypress vine before but will definitely look for that one. Unfortunately, I just traded my white datura seed, before I had the notion of attracting moths I'll just have to get more.

White vertical surface you say, to bad my house is blue, maybe a birdhouse or something of the like.

I just have to second the recommendation above for using Moon Flowers (datura). They bloom late in the evening and are great under the moon!

"lighted", not "white", surface. The moths would prefer a darker surface to blend in with. My house is green and the moths like that just fine, and they would like a blue house.

Of course you do not have to light the surface, but then you would need a flashlight to notice the moths.

You can also attract moths with "bait", a sugary, fruity mix you can google for recipes. Spread some on tree trunks (doesn't take much) and other surfaces in the garden, and check out your bait sites with a flashlight. I find that my moths also like my suet feeder (littie wire cage you can get at Walmart or pet stores for $2-3.00) that I put my black, rotting bananas in. They will attract the fruit feeding butterflies during the day and the moths at night.

I highly recommend Himmelman's book, Nighttime Jewels of the Garden.

I have attached a link to Butterflies and Moths of America so you can see what moths visit Indiana.
