Just in time for Independence Day, things are starting to explode in the garden, so I thought I’d give you another progress update. (There’s a link to all the posts about my native garden project in the main menu, or here.) Come along and look at some of the floral explosions happening in my little corner of the world.

After the spring ephemerals finished, there was a period of time in which nothing much was blooming. Then the golden alexander and wild geranium bloomed and gave me some early season excitement, but then things went quiet again. No flowers, and therefore no insects. Only in the past two weeks have I seen an uptick in things starting to take off. (Note to self: I should probably find some more early bloomers to plant so I don’t have that long boring period with no food for pollinators.)

As I walked around to check on the progress of the various beds the other day, my breath caught in my throat as I saw a buttonbush with actual tiny “buttons” on it!! I knew I was taking a risk trying to grow these water-loving shrubs in my sunny and mostly-dry yard, but this one is really thriving only a year after I planted it. And I’ve not watered it regularly or done anything special to help it along. Two others that I planted in a different location two years ago are still struggling, and I think it might be because there’s a huge root system leftover from the gigantic burning bush I removed in that spot several years ago (a beautiful but very invasive plant from Asia). I continue to fight the root sprouts of burning bush all around the two buttonbushes, and may just dig them up and move them somewhere else if I can find a good spot.

Blue vervain has been a favorite plant of mine for years, and every time I see it I think of the thrill I got when I captured a snowberry clearwing moth feeding on it.

My center island bed is still very much a work in progress, but it’s coming along. When I bought this property four years ago, this bed was full of irises and hostas, and hosted a half dozen bird feeders where seed had accumulated in a thick layer for years. I made a half-hearted attempt to clean it up before planting in it, but I’ve learned a good lesson from that. I should have done a more thorough preparation of the bed because now I have to fight the invading grass and other weeds while trying not to damage the native plants I’ve already put in there. Here’s how this bed looks today.

This bed doesn’t have a defined edge or any type of border yet, so it looks messier than I’d like. The butterfly milkweed (Asclepias tuberosa) is the only one that survived from several I planted last year; it’s jumped out of the bed and I’m probably going to allow it to stay there because this is one native that doesn’t like to be moved. When I get around to putting some kind of edging around this bed I’ll just make a little curve out around that butterfly milkweed. I’ve got a small patch of dotted horsemint to the left (some in a pot), and that’s where I enjoy sitting to watch the large digger wasps that come to pollinate it.

Here’s a great black digger wasp, and the great golden digger wasps also love this plant. Here’s one of them feeding on rattlesnake master, another one of my favorite native plants.

Last fall I removed a Japanese maple tree beside my sunroom so I could use that space for natives. I added a couple dozen pussytoes along with a few butterfly milkweed, calico aster, and a wild fennel plant. The fennel is here specifically because it’s a host plant for the caterpillars of the black swallowtail butterfly. I hope somebody finds it and lays some eggs there!

The pussytoes (Antennaria neglecta) are here for the butterflies too, as they host the larvae of the American lady butterfly.

I should probably take this opportunity to point out the difference between a “pollinator garden” and a “butterfly garden.” These two terms get tossed around interchangeably, and it’s great that so many people want to plant for these valuable insects. But a pollinator garden is designed for adult insects to use the pollen and nectar from the plants — bees, wasps, butterflies, and flies primarily.

The purpose of a butterfly garden, on the other hand, is to provide host plants for the butterflies to use as nurseries for their young. Many butterflies require a specific plant or family of plants, because their caterpillars are only adapted to eat those plants. This is why so much effort has been made to educate people about the fact that monarch butterflies must have milkweed or they will go extinct. The caterpillars of the monarch can only feed on milkweed plants — common milkweed, swamp milkweed, Sullivant’s milkweed, and others in that genus (Asclepias). It’s the same principle for other butterflies, so if you know the host plant for a species you want to attract, you can grow it and get to experience their entire life cycle in your own yard.

If you want to know more about this idea and see a list of host plants for various butterflies, I’ve posted that information for you on our Wild Ones Oak Openings website, here.

And speaking of fireworks, take a look at this shrubby St. John’s wort. This is a gorgeous and fast-growing shrub with glossy leaves and fantastic yellow flowers that look like those big fireworks that radiate out in a circle. I hope you enjoyed this fireworks-themed garden update as much as I enjoyed writing it for you. Happy 4th of July, America, and happy gardening.
