What are your favorite summer flowers? I like many of them. A sunflower unexpectedly has popped up, from seeds a grandson brought over and that we halfheartedly planted. Morning glories are growing like wildfire, and although they have not yet bloomed, I think this will be the year that they do.
Well, both of those are annuals, which can be cute, but I tend to favor perennial flowers. And some of them can be, well, a bit aggressive. I can respect that, the tough, take-no-prisoners, I-own-this-ground bad ass attitudes of certain perennials, which you plant at your own risk, because you will spend years battling the spread of these spreaders.
Still, I planted them, I like them and I’m happy to see them this summer. What are the bad-ass perennial stars of my July gardens?
Here they are five of them, in no particular order:
Tiger lilies. I think day lilies in general have an odd name—I know that the name refers to the idea that each flower lasts only a day or so, but each day lily plant has many bulbs, and this class of flowers, in general, blooms for a fairly extended season. Of all the day lilies, the most vigorous in my corner of Iowa isn’t any fancy hybrid or version of something common to buy in a store like “stella de oro,” but the common Iowa ditch lily. Although some Asian lilies share the same name, in Iowa these aggressive day lilies are known as tiger lilies. And they are tigers. You have to be ruthless with them and cut some out now and then because the will conquer your garden, but with their tall, pretty orange flaming flowers, they are still worth planting.
Cone flowers. I don’t have any of the more subtle yellow native Iowa ones, and hope to add those, too. These are purple cone flowers. I have tried planting various other styles and colors, and purple seems to rule. The large flowers become prickly seed heads that I tend to leave because I like them in winter—but they are full of seeds and they spread like crazy. Like tiger lilies, cone flowers, when established, spread quickly on their own. But they are pretty, attract lots of pollinators and are tough plants that can handle dry Iowa summer.
Common milkweed. I have planted butterfly flowers and swamp milkweed, and I like them both, which are arguably both prettier than common milkweed. Common milkweed, however, is something special. It not only produces copious seeds, but spreads underground via roots, something the other milkweed varieties don’t do. In my experience, common milkweed is the hardest to get going—it doesn’t germinate easily, you have to plant in it fall so the seeds can overwinter, and it only grows where it really likes the environment. But if starts to grow, it doesn’t stop. It is aggressive and hardy and easy to admire.
Hostas. A plant related to day lilies, but way more fond of shade, these plants tend to be grown more for foliage than flowers, although I do like their pretty little flowers, too. I know many gardeners get miserable fighting the spread of these flowers, but I like them. They do burn up and fade if it their spot gets too sunny, but are kings of the shade. And, personally, I have planted a lot of these, and although they can take over a garden, I just let them and enjoy.
Trumpet Vine. Most aggressive of all of these plants which all try to spread, plant this climbing vine only if you’re ready to engage in battle with it in future years. Via both root and seed, this native plant is ready to take control. I planted one vine a few years ago in the east end of my garden, and I am constantly having to pull these vines as they try to spread beyond where I want them. But it’s a pretty flowers and if you don’t mind the future fight, I say go ahead and plant it. Just realize that if one survives, it will be dozens in a few years, and in other areas of the garden, you’ll be constantly cutting back and pulling this pretty, but bad-ass aggressive, native flower.
In my gardens, July is the month where most of these are in bloom. Common milkweed has already bloomed, but is putting out buds for future blooms. Many hostas have already bloomed and faded, but there are some still going strong. Mid-summer is Tiger Lily season, and these tall, proud, sassy Iowa flowers are going full throttle right now. My trumpet vine is a little late—with a new fence project, the original monster vine was cut way back, but it sprouted new growth (of course) and that growth is covered with flower buds (of course), and it won’t be long until the trumpets are blaring in their orange beauty in my summer gardens.
There you have it, five of the meanest, sassiest, nastiest summers flowers that I love and plant and am enjoying in my Iowa gardens. What are your favorite July flowers?
