What Are These Tiny Blue Flowers In The Yard?

Flowering plants number in the thousands or hundreds of thousands actually. Indeed, the huge variety of types of flowers is one thing that draws me to them…the seemingly infinite arrangement of colors, shapes and sizes.

Sometimes I find a flower that is more of a curiosity than anything else. Take for instance these tiny little flowers that come out in early spring. You can find them appearing in flower beds and walkways, along roads and in lawns.

To find out what these little plants are, you’d need a weed book, I guess. The flowers are so tiny as to disappear from view in a short distance. With blossoms that are 1-2 mm across, these posies won’t appear in a wildflower book for their flashyness. Not exactly eye-catching, unless you’re on the ground with them.

Those that we see in the lawn near the garden have a tiny blue flower with four petals. In the center of the blossom is a white ring that surrounds a couple of light-colored stamens. The flower looks like it belongs to the Speedwell group.

The plant has a sprawling habit as it sends out hairy, maroon runners in all directions. The broad, spade-shaped leaves along the runners are scalloped on the edges and lie opposite one another. Where the runners terminate, the leaves become less broad and they’re more tightly packed together. Flowers appear singly in the leaf axils. Photos taken 3 May 2011.

Right next to the tiny blue flowers were a bunch of tiny white flowers. These little curiosities appear in the lawn each spring.

The tiny white flowers seem to be a form of speedwell also, with opposite leaves that are jagged or notched. The leaves are similar to those of the tiny blue flower, except drawn out or stretched into thinner, oval shapes. The white flowers have fours petals and occur at the leaf nodes, not terminally. Overall, the tiny white flower plant is taller and has more vertically rising stems than the tiny blue flower plant.

So, it’s just a curiosity I have about these little plants. I suppose that ants or flies would pollinate the tiny flowers. Plenty of them get pulled out of flower beds or mowed down by the lawnmower, but sometimes they come back.

It turns out that the tiny blue flowered plant is called Corn Speedwell, Veronica arvensis. I came across its picture when looking up Blue-Eyed Grass in the Audubon Field Guide to Wildflowers. Corn speedwell is not native to America, nor does it appear to have edible or medicinal qualities.

Mustards Blooming Bright Yellow in Fallow Fields

Some of the alien plants aren’t all bad. They’re here because humans brought them here, either on purpose or by accident. We’re stuck with them, so why not try to enjoy the aliens or non-natives?

If we see there is direct competition, we may be able to help our native friends out. For instance, when the garlic mustard gets too numerous along the lane, we just walk down the lane, pull out the plants, and let them lay on the road. They’re shallow rooted and very easy to pull up, especially in the Spring when there is a lot of moisture to the ground.

The plants left to lay in the road should dry up and not be able to grow more or set seeds. I enjoyed seeing that the ‘keepers of the forest’ at Little Buffalo State Park do the same thing. On my trail walks there I’ve seen the pulled out garlic mustard plants withering in the middle of the trail.

After pulling up the garlic mustard plants there will be fewer plants the following year. They won’t be extinguished as there are very short plants, maybe six inches tall, that bloom and most likely set seed. The little plants more easily hide from us weed-pullers, so they probably will help to produce the following generations.

Another alien plant that blooms prolifically and will always be here is the mustard plant. The Peterson Wildflower Guide tells us there are several alien mustards, Brassica spp., in the Eastern U.S. – white mustard, charlock, black mustard, chinese or indian mustard, and field mustard. You have to look at the foliage to determine the species.

Bright yellow four-petaled flowers in terminal clusters and slender erect seed pods are common characteristics of mustards. When you have a mass blooming of mustard in open fields, it surely gives a lot of color to the landscape.

Of course, the mustards are edible. If one was the industrious type she could harvest the young leaves for cooked greens or salads. The older leaves are too bitter, so collecting mustard leaves has to be done on the earliest warm days of Spring. The seed pods can be pickled and the ripe seeds can be ground to make a spicy mustard.
