Which varieties of perennial flowers bloom with red flowers in spring

Today, the editor will share with you information related to plant knowledge; next, I will introduce it from these aspects: what are the common perennial flowers?

Perennial flowers refer to herbaceous plants that live for two years or more. The following are several common red perennial flowers that bloom in spring.

1. Dahlia

Dahlia is a plant in the order Asterales and the family Asteraceae, belonging to the perennial flowers. Its flowers are red, and its flowering period is from February to May each year.

The growth of dahlia has relatively high soil requirements. The most suitable soil for dahlia growth is well-aerated sandy loam. Once soil clumping occurs in the dahlia pot, it must be dealt with promptly; otherwise, it will seriously harm the growth of dahlia and, in severe cases, may even cause the death of dahlia.

During its growth period, dahlia has a relatively high demand for nutrients. Because dahlia is relatively large in size, in addition to regular daily fertilization, an appropriate amount of additional fertilizer is also needed during its growth period.

2. Canna

Canna is a plant that often blooms in spring and belongs to the perennial flowers. Its flowers are red, and a fully grown canna is between 1 m and 1.5 m in height.

When cultivating canna, we need to control the environmental temperature in which it is placed. The most suitable temperature for canna growth is between 15°C and 28°C.

There is a little trick to cultivating canna: every spring, that is, during the flowering period of canna, placing canna in a slightly cooler place can effectively extend its flowering time.

Canna is a plant that needs a large amount of water to grow vigorously, so when cultivating canna, we must water it frequently. Do not worry about overwatering; go ahead and water boldly, as long as the water does not flow out from the small hole at the bottom of the flowerpot.

3. Portulaca

Portulaca often blooms in spring. This species of portulaca is bright red, usually opening at noon each day and closing in the early morning of the next day. Portulaca is widely planted in our country and is a relatively common perennial flower.

The growth of portulaca does not have a large demand for water. The watering frequency can be kept at once every half month. However, it should be noted that when watering portulaca, we must ensure that the soil of the portulaca has absorbed sufficient water.

When cultivating portulaca, we can appropriately prune its branches, especially during its growth period. Pruning away some useless branches can make portulaca grow more vigorously.

Common perennial flowers include: black-eyed Susan, daylily, bleeding heart, coreopsis, etc.

Black-eyed Susan

Cultivating black-eyed Susan is also very easy and does not require frequent care. The most suitable growth temperature for black-eyed Susan is about 10 to 30°C. During ordinary cultivation, there must be sufficient light. When it blooms, nutrients must keep up, and at the same time the soil should be kept in a moist state.

Daylily

To cultivate daylily, you need to choose soil with good drainage. If it is during the growth period, you can water more. Of course, when fertilizing, we should also pay attention: generally in the second year of planting, fertilizer should be applied three times as a top dressing. If the weather is not particularly dry, then there is no need to water.

Bleeding heart

Bleeding heart is also a relatively common perennial flower. When cultivating bleeding heart, you must pay attention to the issue of watering. The amount of water varies by season. Generally, in spring and summer when the weather is hot, watering once every one to two days is enough. If it is rainy weather, then watering once every five days is enough. In winter, there is no need to water frequently.

Coreopsis

Coreopsis is a relatively common perennial flower, and its medicinal value is also very high. When cultivating coreopsis, it must not be allowed to grow excessively, so the amount of water must be controlled well. Generally, after planting coreopsis, it must be watered sufficiently. Even during ordinary maintenance, special attention should be paid to watering. Generally, watering can be done after the soil dries out.
