These roadside flowers can be propagated just by picking some seeds, and they bloom especially brilliantly

If you haven't grown some beautiful perennial flowers in your yard, it definitely won't look as fresh and lovely. For me, if I don't plant some perennial flowering plants in a small yard, it definitely feels incomplete.
The simplest way to grow perennial flowers is by sowing seeds. For beginners, it's best to choose flowers with a relatively high germination rate. Buy some seedling trays and special succulent soil, and they'll be very easy to grow. You can sow and propagate in both spring and autumn.
1. Delphinium
Also called larkspur, it is a perennial plant with very tall flower spikes that can grow to nearly two meters high. Its flower stems are very tall, and the blooms hang in clusters like colorful flying sparrows resting on the branches. The flower colors are very charming, with the common blue, white, pink, red and purple, etc.
Delphinium seeds need about 14~20 days to germinate. You can first place them in a dark spot and keep the environment warm and moist, and they will sprout quickly. You can grow them in special seedling soil, keep the soil moist, and place them in a warm, shaded environment. After the seeds sprout, move them to a spot with bright, indirect light.
2. Columbine
Columbine is suitable for planting in a relatively sheltered spot. It grows very delicately and charmingly, with different flower colors and rich varieties, and is highly ornamental.
Columbine seeds take about three months to germinate. As long as the seeds don't rot, definitely don't give up.
You can sow in spring and autumn, choosing loose, breathable, well-draining sandy soil. You can mix some peat moss into the soil, keep the soil sufficiently moist, and place it in an environment with appropriate bright, indirect light. Keep the environment warm and the soil moist.
When planting columbine, leave appropriate spacing and separate them properly. They are very cold-hardy, and after withering in winter, they can resume growth once spring warms up.
3. Black-eyed Susan
Black-eyed Susan is a perennial flowering plant, with common yellow and dark red flowers. As long as the temperature is above 15 degrees, you can choose to propagate by sowing. Keep the soil moist, and the seeds can germinate within three weeks.
4. Spiked speedwell
Spiked speedwell has as many as hundreds of varieties. They are all very easy to grow and easy to cultivate, and you can even see their wild varieties growing in the wild.
Spiked speedwell usually blooms from June to September. If it's a place that's warm year-round, it can even keep blooming all four seasons. They also grow well in containers and are suitable for propagation by sowing. Prepare loose, breathable, well-draining soil, sprinkle the seeds evenly on the surface of the soil, cover lightly with soil, then keep the soil moist, and they will take root and sprout within a few days.
