Inventory of 15 species of perennial root plants with heat tolerance index above four stars

Hot, hot, rainy, dry and infested with insects, summer is the biggest headache for gardeners in the south.

But no matter how bad the conditions are, there are always some excellent plant babies who can grow healthily under pressure, and some who can produce touching flowers.

Today, according to my performance in summer in Shanghai, I would like to count those perennial root plants that are not afraid of high temperature and bloom in summer.

First of all, I emphasize the concept that perennial root plants should first of all be cold-tolerant and able to survive the winter, so those plants that are heat-resistant but cannot survive the winter are not included in today's discussion.

1, echinacea. Heat resistance index: ☆★★★★

It begins to bloom at the end of spring, and the traditional varieties are pink and tall. In recent years, there have been many varieties of dwarf potted plants with richer colors. You can blossom all the time in summer. Pay attention to pruning the residual flowers. After setting seeds, there will be fewer blossoms.

Double petal varieties feel less heat-resistant in my attempt, which may also be related to the short planting year.

2, heat-resistant sage. Heat resistance index: ★★★★

Including sky blue sage, deep blue sage, red lip sage and so on.

Generally blooming in early summer, sage is slightly less heat-resistant, pruned to half of the position after flowering, and will blossom again in autumn.

Deep blue sage will be open all the time, the hotter it is, the more it will be opened, and it will be very strong. It has a drawback, although it is not as serious as peppermint, it also likes to spread.

The habit of red lips is similar to that of sky blue, but there are slightly fewer flowers in summer and bloom again in autumn.

3, Jinguang Chrysanthemum with black heart. Heat resistance index: ★

The traditional heat-resistant varieties are very strong and can blossom continuously. Sometimes the leaves will be scorched and removed in time to avoid getting sick. Cut the flowers in time.

In recent years, there have been many varieties, such as double, crimson and so on. Pubang Chrysanthemum is also one of them.

4, hickory. Heat resistance index: ☆★★★★

A very elegant variety begins to blossom in May and is cut after blooming, half of each pruning. It blossoms again about 2 months after pruning. It is very strong and easy to raise.

5, brocade group carnation. Heat resistance index: ☆★★★★

There are many varieties of carnation, to choose heat-resistant must recognize the variety of brocade group, the leaves are relatively wide, tall, flowers into a ball. Sometimes it is also called cut carnation. Especially recommend the perfect series in recent years.

Carnation is also cut after opening. As long as the cut, the next crop will open, 40 degrees open without mistake.

The ground cover for greening is not as good as the heat resistance of carnation, millet, and other short carnation.

6, American mint. Heat resistance index: ☆★★★★

My family's everlasting variety, the so-called one-time sowing, life-long benefit from that kind of good thing. The leaves are so fragrant that you can make tea without blooming. If there are many flowers, there is only one season in early summer, and it doesn't matter whether you cut it or not. The north can drive for a long time. Seed pods can be retained after flowering as an ornamental in autumn.

7, Platycodon grandiflorum. Heat resistance index: ☆★★★★

The color is very cool and full of oriental beauty. Radish roots are afraid of stagnant water, so the planting site should be kept dry. Although Platycodon grandiflorum is perennial, it does not live long and will not grow into an old Platycodon grandiflorum like a thousand-year-old ginseng.

The seeds will be replanted and replaced in three or four years. There are potted varieties in recent years, which are worth buying.

8, Hemerocallis. Heat resistance index: ☆★★★★

There are many flowers, many varieties, and the leaves are a little messy, so they are suitable for large areas. Cut off the flower branches after blooming. I prefer the traditional variety I like to eat. The flowers are thin, yellowish, elegant and, most importantly, edible.

Day lilies are poisonous and should be blanched with boiling water before eating. Remember.

9, Fine Leaf Beautiful Sakura. Heat resistance index: ☆★★★★

There are many varieties of beautiful cherry, only this variety is particularly heat-resistant, the wide-leaf variety with many colors is not heat-resistant.

Another species of willow verbena of the same genus, tall and magnificent, can also be kept in bloom, planting a few trees on the edge of the ornamental grass, which is very hazy.

10, hollyhock mallow. Heat resistance index: ☆★★★★

In fact, hollyhock in the south can only be called early summer flowering, and the florescence coincides with Meiyu, double flowers are easy not to open. In the north, especially in the dry northwest, you can keep driving. My family has a good single specific gravity valve.

Sunflower is better planted than hollyhock and can sow itself. It's a wild style. Farm music is a must.

Both varieties are easy to sow, sowing in autumn and blooming in spring, which is very suitable for beginners.

11, Aster. Heat resistance index: ☆★★★★

Aster flowers are small, multi-flowered, and easily bloom into balls.

Most asters also have two seasons of flowers, such as New York chrysanthemum and Dutch chrysanthemum, which bloom one season in early summer, prune immediately, and bloom another season in early autumn.

Aster does not wither if it is not pruned. If you leave it alone, the autumn flowers will be much worse. So after watching it for a while, cut it off before the plum rain.

12, Sugen Fu Lu Kao. Heat resistance index: ☆★★★★

The necessary gardens in the north, the performance in the south depends on the planting position, but also depends on the variety.

In several varieties of my family, Miss Pepper performs better than the popular Miss Holland, while the traditional Purple Red performs better than Miss Pepper.

In a word, the uglier the design is, the stronger it is.

13, Dahlia. Heat resistance index: ☆★★★★

The flowers are big and colorful, although the main florescence is in the spring and autumn, but the summer performance is also very good. After pruning, flowers can keep popping up. Like dry, do not like wet, otherwise it is easy to powder. Occasionally attract aphids and other bugs, but these are nothing compared to its gorgeous face.

If you bury it deeper in Shanghai, you can spend the winter in the open field without pilling.

Three points should be paid attention to in planting: prevention of waterlogging, prevention of insects and prevention of neighbors.

14, mountain grasses. Heat resistance index: ☆★★★★

Although most of the mountain weeds are not very heat-resistant, the following are no pressure to spend the summer and can blossom carelessly in my home.

Tang Songcao, flowers needless to say, we refer to a variety of network celebrity Meitu, but also blooming in early summer, unexpected heat resistance.

Ground elm, red cones are rich in mountain flavor, very strong.

Sand ginseng, quite heat-resistant, small bell clang flower, a bit like lodging. Once I bought a jin of stewed old duck sand ginseng to open a place of blue wind chimes.

15, perennial root ornamental grass. Heat resistance index: ★

Ornamental grass is grass. Perennial root varieties include pennisetum, awn, Phragmites communis, small judgment grass and so on.

Pennisetum will blossom in the middle of summer, and the flowers can last almost all summer. When Puwei blooms in early autumn, they are all good at heat resistance.

It should be noted that the root system of ornamental grass is well developed, and it may wither due to lack of water if it is dry for a long time, especially in potted plants.

Finally, I wish you all to choose the right heat-resistant roots and spend a summer that is no longer just death.
