Roadside wildflowers can be stunningly beautiful too. Do you know all of these?

Many gardening enthusiasts always come across lots of wildflowers by the roadside, but most of them don't know what these wildflowers are. Today, let me introduce a few kinds of roadside wildflowers.
Iris
The iris generally grows mostly on grasslands, and it is very salt-alkali tolerant, so it especially likes to grow on salt-tolerant flower meadows.
Its flowers are especially large, and the flower colors are also very rich and vibrant. It especially loves sunlight, and the plants also come in three types: short, medium, and tall.
Chinese violet cress
Chinese violet cress is also called February blue, and it always blooms beautiful blue flowers around the second month of the lunar calendar.
Chinese violet cress has a very strong ability to adapt to the environment, and it especially likes environments with ample sunlight, fertile soil, and moisture.
Dandelion
Everyone should have seen dandelions; no matter where you are, you will see them. After blooming, it is a small, white puff, and when the wind blows, it flies away.
Whether on hillside grasslands, in fields by the roadside, or even on riverbanks, you can see it. Wherever its seeds drift, that is where it grows.
Veronica
Veronica flowers come in three colors: blue, white, and pink. It is a herbaceous plant, and after blooming, it looks as if a layer of flowers has been spread on the ground.
Annual fleabane
Annual fleabane has a very strong reproductive capacity. Its flowers are very small, and it generally blooms from June to August. The flowers are light brown and have a slightly bitter taste.
