Nectar plants for Swallowtail Butterflies

Nothing makes me smile more than going out into my garden and seeing Swallowtail butterflies fluttering around.  Did you know that planting certain plants will make sure that you have these pretty visitors to your yard? These swallowtail nectar plants are great at attracting butterflies to your garden. They just can’t resist them!

These swallowtail nectar plants are like a magnet for the pretty butterflies

Swallowtail butterflies are very large and colorful butterflies in the family Papilionidae.  The family is huge and includes over 500 species.  The majority of the butterflies are tropical but you can find them on almost every continent. I am very lucky to have them as common visitors in my garden.

With such a gorgeous butterfly, it stands to reason that the caterpillar would be showy too! One an almost imagine the change to come after the butterfly emerges from the cocoon just by looking at the coloring.swallowtail caterpillar

This swallowtail caterpillar loves to feast on  any of the carrot family plants,  such as dill, parsley, fennel and others.  While you may not enjoy him devouring these plants, he needs to grow and feed to become gorgeous like the photos below.

If you would like to attract Swallowtails to your garden you can do a few things to bring them near.

  • Provide a water source. A small pond or birdbath will give them places to drink.
  • Add rocks in your garden to give them a place to rest. (I like adding a big rock in my bird bath.)
  • Plant tall grasses, such as Japanese Silver Grass, to give them some shelter at night.
  • And most important, plant some nectar plants to give them something to fee on.

( can’t even begin to count the times that I’ve walked out to my deck garden to get some parsley and found that it has been stripped clean by swallowtail caterpillars. They LOVE the stuff. Just goes to prove that parsley is a spice loved by all! Dill and fennel are other food plants that they favor.

Joe Pye Weed

This stunning native perennial can grow to 9 feet tall. One of the nice things about this plant is that it blooms in the fall months, attracting butterflies well into the cooler time of the year.

Butterfly Bushes

If you want butterflies, (and not just swallowtails) in your garden, be sure to plant Buddleia, commonly known as Butterfly bushes. There is hardly a day that goes buy in the summer when I don’t have dozens of swallowtails feasting on the butterfly bushes in my front garden bed.

Purple coneflowers will attract Swallowtails as well as bees.  Be sure to leave the spent flowers when the colder temps arrive and the plant goes dormant. The birds love the seed heads, too!


Even certain succulents will attract swallowtails.  This variety is Sedum spurium “dragons blood”.

All of my sunflower plants are attractive to swallowtails.  How majestic is this pairing?  A huge butterfly needs a huge flower, after all!  This female swallowtail has the perfect markings for this flower. No wonder she is so attracted to it!

My neighbour and I grow the Monarch butterlies here in Florida, and we lose a lot of caterpillars. We bring a lot inside and put them in our mesh enclosures. We know the bees get them and I see a lot of lizards on the Milkweed bushes and Im wondering if birds might eat them but not so sure about that. We have had very upsetting issues with our Milkweed bushes being sprayed with pesticides before we buy them. We now wash our bushes when we bring them home.

If the chemical are neonicitinoids they are systemic and do not wash off. Be very careful and ask plant suppilers what chemicals were used. Safest thing is to buy plants from native plant nurseries near you. Or, from organization like wild Ones who often have plant sales and offer much info.

We have fennel, parsley, dill and a host of flowering plants to attract butterflies in our beds. In particular last year and to God's glory this year we again have black swallowtail caterpillars and so far one crysalis. I am very puzzled....each day ( actually several times a day) I go out and check on the caterpillars on the fennel. Last week we had a total of 12 caterpillars, slowly each day dwindling down to this morning when to my dismay I counted only 5 and now it's late afternoon and we are down to one very hungry caterpillar and still the one crysalis. Can you please explain to me what has happened to them? Our fennel is tall and big so there is plenty of room for lots of caterpillars! I even check our dill and parsley. They have not moved to those. I will greatly appreciate any reason you can give me for their disappearance. Sad in East Texas. Rochelle

Hello, I believe the cause of your missing caterpillar’s are most likely birds eating them. That’s why I usually bring them in my house in to a container or cover them with a light mash while still in The garden

Hi Rochelle, I have no idea what is causing the disappearance. I see less and less butterflies and bees as the years go by but don't know why a specific group would disappear. Perhaps a reader will have some opinions.

Oops, I really meant to say in my note, above, to provide native plants for the butterflies (not hummingbirds. . .though they need them, too!)

Sorry for the typo. I probably was looking at my hummingbird feeder or just a senior moment.

Hi, thank you for posting caterpillar photos and all the pretty photos and identifying the plants.

Some people are very interested now in providing native plants (for their state) to provide larval food as well as nectar for these beautiful hummingbirds. On our native plant Facebook page, it was suggested that ironweed as well as joe pye weed was suitable for swallowtail butterflies. Do you know of any other native plants they will visit or use as larval food (i.e., plant their eggs upon).

Meanwhile, I wanted to mention something I just learned about this year. There is concern over pesticides (particularly the kind known as "neonicontinoids" or "neonics" for short, that are used in bedding plants and flowers you buy at the "big box" stores (like Home Depot and others). These stores were usually my sources (except for an herb gardening club's sales) for flowers and vegetables. The plants are marked somewhere on the labels so a careful shopping can read the label to avoid buying plants with these pesticides. As you know, pesticides can be harmful to our pollinators, which include butterflies, bees, and others. Also did you know many many flies look like bees? They can also be great pollinators.

Thanks for sharing my picture, Carol! Boy they're hard to get a good clear photo of, they never sit still. They're giddy with delight when they find a new flower open. I find that ever since the willows grew up there are more of them - the caterpillars need willows to live on.
