Well, despite there being a lot more days with below average temps than at or above average where we live, signs of spring are everywhere and our plants are starting to come up. I even saw my first butterfly of the year. A mourning cloak, which overwinters as an adult butterfly. We overwinter our plants outside to try to keep them on a natural schedule. Some of our plants keep some green all winter, others are just starting to poke through the ground and still others need a bit warmer temps before they start sending up new growth. We have sold some of our plants through the winter in a dormant state and list them as such on our website and Etsy store. As they start popping up for the year, we list change their listing to reflect this. We have a wide selection of plants for a butterfly pollinator garden and add new ones every year. The ones we have available now are all one year old, but we are currently starting seeds and as those have sufficient enough growth, we will be listing them too. Our plants can be currently be purchased through this website https://www.blazingstarbutterflygarden.com/ or our Etsy store Etsy Blazing Star Butterfly Garden We also have pickups by appointment at our location. Here is a list of what we have available and hope to have soon:

It is still winter here in Southwest Michigan and if you are like me, longing for warmer weather and “butterfly season” to begin. The term “Cabin Fever” feels like it has a lot of meaning. Although most butterflies aren’t really active until at least May, there are signs it’s getting closer. Spring officially starts on March 20, but you may hear the term meteorological spring which basically divides the seasons by month. So March, April, May, is classified as spring. Still doesn’t feel like it, but this is the first week in seemingly forever that the high temp every day is forcasted to get above 32F/0C. It also appears that some animals have started to notice.
There are some birds that do not overwinter very much further south than Michigan. Some might not even migrate at all but find a good location to hunker down nearby. When a little warmth arrives they start moving around looking for suitable future nesting spots, returning to established ones, and establishing territory. Some that I have seen (or heard) recently are the sandhill crane, bluebirds, and killdeer. All who have easily recognizable calls, and in the case of the sandhill crane…loud!
So what about butterflies? It may be a while yet, but some butterflies overwinter as adults, finding safe places to overwinter. The mourning cloak, questionmark, and comma butterflies all overwinter this way. They have been known to come out on warm sunny winter and early spring days to sun themselves and possibly feed on oozing tree sap (another spring sign) I haven’t seen one yet, but someday soon?
It’s winter and we are getting cabin fever wishing butterfly season would return. Butterflies overwinter in each of their stages (egg, larva, adult) depending on what species. One of the more easier species to find in winter, depending on your vision, are our “limenitis twins” The viceroy (limenitis archippus) and the red spotted purple (limenitis arthemis astyanax). Their caterpillars overwinter in a small cocoon like structure, a hibernacula, where the caterpillars sit and wait for spring. Both are found in our region of Michigan. In my observation, they do seem to have some differences in habitat preference. Red spotted purples seem to be more common near woods and viceroys more in open areas near wetlands
These species of butterflies are known as mimics. The Viceroy mimics the monarch amd the Red spotted purple mimics pipevine swallowtails, minus the tails. The butterflies they mimic are distateful or toxic so it appears to offer some protection from predators.
Despite looking very different as adult butterflies, the caterpillars are identical. They primarily eat the same hosts but seem to have favorites. Red spotted purple tend to favor choke cherry or black cherry and viceroys seem to favor willows. Both will readily use cottonwood or aspen as well. (This is probably the reason for my previously mentioned habitat prefernces). The adult butterfly will usually lay its egg at the top of the very tip of the leaf. After the caterpillar hatches it will work on eating the sides of the leaf leaving the midrib. This tends to make them easy to find if you want to observe them in the wild. The images I took were on the side of the leaf which is not typical, but you can still see how the egg looks and how they leave the vein or midrib.
As the caterpillar matures it can be either green or brown and resembles bired poop. When disturbed, the caterpillar will arch its head down with its antennae out. To me its antennae look a lot like an ant which makes me wonder if it offers some protection as many insects avoid ants.
Here in Michigan both the red spotted purple and viceroy will have two generations and a possible third. The overwintering caterpillars will make a chrysalis in May and then the following generation will make a chrysalis in mid summer.
As the days get shorter and nights get cooler, the small caterpillars will make a hibernacula to overwinter. The caterpillar will attach these small open ended cocoon like structures to the branch and remain there all winter. The caterpillars can be seen crawling around on warm fall days, but no longer eats. When the days get cold it will stay inside. Even on the coldest of winter days, the little caterpillar can be seen inside. It can be a fun activity to beat the winter blues going out and looking for the overwintering limenitis caterpillars!
(Silver spotted skipper on tall verbena)
It makes sense that native plants are great for pollinators as they have a history of working together. Even so, we’ve got some favorites that aren’t native too. Here are our four favorites that we sell: Tithonia, Tall Verbena, lovage, and rue.
(Monarch butterfly on tithonia flower)
Tithonia (also called Mexican sunflower) is native to Mexico and from what we have read, is a common roadside plant in areas. It gets incredibly tall, 5-8 ft and covered in bright orange flowers that pollinators love. It loves the summer heat and grows like crazy when hot and it’s tolerant of dryer soils. This plant is not only a pollinator magnet, but also loved by hummingbirds. It continues blooming right up to frost and has lots of nectar for migrating monarchs. I tell people who enjoy photography to get these plants and then just go stand out by them in summer. The action never ends. The only thing that is a downer is that it gets so big, some people don’t have room and that it is an annual (gotta replant each year), which surprises many because of it’s size.
(Giant swallowtail nectaring on tall verbena)
Tall Verbena is another fantastic nectar plant that butterflies and other pollinators love (hummingbirds too!). It gets 3-5ft with narrow stems and light pink/ purple flowers. It’s a very adaptable plant. We get a lot of daytime flying sphinx moths (hummingbird clearwing/ white lined sphinx) at ours. Zebra swallowtails seem particularly fond of it too. It’s foliage is very similar to it’s native relatives, blue vervain and hoary vervain. This is another annual. One negative I have noticed about it is that it is a good self seeder and one needs to watch to make sure it doesn’t show up where it is not wanted.
(lovage starter plant)
Lovage is a perennial herb that gets the nickname “poor mans celery” because of it’s similar taste. It is in the same family as celery and other garden plants like dill, fennel, and carrot. Like these it is the host for black swallowtails. The reasons I think these are great plants is that unlike it’s garden relatives, lovage is a perennial. It also loves cool weather and grows quickly in the spring. When the overwintered black swallowtails start emerging from their chrysalis in spring, lovage has lots of foliage for their caterpillars. Lovage doesn’t really like heat, so they can look haggard in summer, but bounce right back in fall and survive frosts till we get a good freeze.
(Baby Giant swallowtail caterpillar and egg on rue)
Rue is another perennial herb. It generally stays under 3ft and has woody looking stems from which it sends out new growth in spring. It gets little yellow flowers in early summer. I often get asked what pollinators like the flowers and it doesn’t seem to be a favorite of many, but the one I do notice on them are mud dauber wasps. Mud daubers are beautiful (black and metallic blue/ purple), not aggressive like some wasps, and good pollinators. The great thing about rue is that it is the host for both giant swallowtails and black swallowtails, which use hosts from different families. With a rue plant you can find caterpillars of either and witness either species female butterflies laying eggs. One thing to be careful of is that the foliage can cause a rash in susceptible people.
We anticipate having all these plants available this season.
(Viceroy butterfly on tithonia)
We start our seeds using a variety of methods depending on what type of plants they are. Our plants are all intended for butterfly/ pollinator gardens and many of the best plants for these gardens are native. While some native plant seeds can be directly sown, like many vegetables or annual flower seed packets, most require special treatment to get them to germinate. The most common treatment is called stratification, which is basically a process to mimic winter. Depending on what kind of plant, stratification usually takes 30-120 days. Some plants, particularly many woodland shade natives, require two cold dormancy periods to germinate.
In addition to stratification, some seeds are small and need to be surface sown and receive light to germinate, others have thick hulls that need to be need a treatment to open, and others prefer to go through a real winter, rather than an artificial stratification period. Because of this, some of our seeds are started in trays in greenhouses, some are kept in trays outdoors all winter, and still others can be started using compressed soil blocks.
Once our plants are started, we transfer them to biodegradable fabric bags. We feel that this is what really sets our plants apart from most growers. Most nursery plants are grown in cheap plastic containers. This is a cheap way to propagate plants, but can have disadvantages. One, the plastic can get very hot in the sun and shock/ stunt the plants. Two, the roots in plastic pots are often circled and grow into each other, a term referred to as root-bound. This can make it more difficult and time consuming for plants to root out and require more work and water to get them started.
Although more labor intensive, we grow our plants in biodegradable fabric pots. The fabric is made from a plant fiber and takes a couple years to start breaking down. The best advantage is that the roots grow outward and are well aerated and not circling. They are eager to root out. Most people notice that they start to grow much quicker once planted and require less watering. Also, it makes them easier so start during periods when many people quit trying to start new plants (The heat of summer and winter)
When you order plants from us, we suggest planting them as soon as possible. Whether is is spring, summer, fall, or winter, as long as the ground is workable, they will keep growing new roots. (However if you order dormant plants, don’t avoid watering them just because they don’t have visible growth) Despite being small, they do much better in the ground than being transferred to a another container till they get larger (unless you intend to keep them in a pot). (As previously stated, keeping plants in black plastic pots can cause root circling and root shock). You can either plant the biodegradable pot with the plant, or remove and compost it. If the plant already has an abundance of thick roots, we suggest just keeping it on. You can also score up the side of the pot for easier root penetration. If you receive regular rainfall, regular watering may not be needed, but check the soil at the base of the plant to see if it feels dry. If you ever have any further questions about growing our plants, don’t hesitate to contact us. We want growing a butterfly/ pollinator garden to be an enjoyable experience.
