I would like to ask what plants are suitable for the rooftop

Spider plant - I recommend it, because it can change the air and is also very dry resistant, if you are an office worker, it is the best choice. If it is raised well, it can also produce small white and refreshing flowers jasmine - mainly because of that fresh fragrance. Give it a try.

A lot. Pretty much can.

Just don't be too big.

There are also those who are very afraid of heat, don't keep them on the rooftop.

Most can.

If you are too afraid of the heat, just use a black sand net to shine it.

Big rooftop?? Build a shed and grow vine loofahs (this one will be eaten quickly), grape grapes (this one will take several years to eat) or wisteria flowers or something.

Then you can plant all kinds of potted flowers below. It's best to have sunlight and not get direct sunlight. However, because it is not planted directly on the ground, it should be watered frequently.

The loofah is planted on the balcony of my house, and the drunken butterfly flowers are planted below, begonias, white orchids, aloe vera, camellias, water lilies, sunflowers, impatiens, etc., all grow very well

Spider plants and ivy are good choices, and they are evergreen all year round.

Petunias, half-branched lotus, can add a lot of color to your balcony, but the flowering period is in spring and summer. Pansies can be planted in winter.

Do you mean terrace? That's the best, it's easy to raise any plant, unlike a closed balcony that lacks wind and sunshine, and I envy you. It's just that the plants you grow need to be watered more, and the plants of the cactus family in the rainy season should not be waterlogged.

I have ordinary flowers to give you, but I don't have a pot anymore, only seedlings.

I've always loved clemat ferns, but I've never kept a pot, and I later learned that this plant only has a half-year lifespan, so I finally gave up on the idea of raising another pot again and again.

I have lived on the top floor for some years, the original roof was bare, and the roofs of the high-rise buildings were waterproof and insulated, without a trace of life. After years of wind and sun, layers of dust covered the rooftop, and gradually the rooftop became green, first moss, then weeds, and finally diverse.

The rooftop of the high-rise has an elevator machine room, probably because the machinery needs to dissipate heat, and the outer wall of each machine room has an air conditioning unit, which is open all day long, and the water plants near the drain outlet of the air conditioner have also begun to be rich and diverse. I don't know most of the plants, and I can't tell if the names are correct or not, but I have tried to scatter grass seeds in a small area for some seed-bearing plants, and the densest grass under the current air conditioning outlet is the result I got.

I have also tried to pull out some rhizomes, most of which are difficult to take out of the brick joints completely, and I can't help but sigh that they are absolutely tenacious compared to the carefully cared for flowers and plants in the greenhouse. At first, most people will subconsciously ignore it, and at most they will flash their thoughts and characterize it as a weed, but after looking at it for a long time, the unsightly rooftop plants attract me even more. What I see is vitality, tenacity, stubbornness.

Of course, they are harmful to the building, and a plant with roots of more than ten centimeters has been pulled, and of course I can't name it, just below this location, which is probably the place where the roof of my house leaks.

But I still admire these plants, and there is actually a French plane tree among them, and I will visit him every time I walk on the rooftop, of course, I don't want to intervene for a while, and one day he will be removed, but before that, I think it is possible to transplant him in the land downstairs, and the land where Peikong is now blocked may not be able to accommodate such a rooftop plant.

The rooftop has sufficient sunlight, and some strong positive plants can be planted, such as water lilies, bowl lilies, cacti, sunflowers, etc. They need to be cultivated in the sun and rely on chlorophyll for photosynthesis to provide nutrients for better growth.

Water lily is a long-day plant, with sufficient light and good ventilation. Water lilies have different water level requirements at different stages of growth. At first, the water level is slightly lower than the edge of the pot, and gradually increases as the leaves grow.

In the early stage of potted water lily growth, the bottom fertilizer should be sufficient, no need to top dressing, and the fast-acting potassium dihydrogen phosphate should be applied at the flowering stage. Throughout the growing season, care should be taken to remove weeds, dead leaves and algae from the water surface in the pots.

Cactus, watering should be divided into seasons, once every ten days and a half in winter; The temperature is 15 to 25 degrees Celsius can be watered normally, once every two days, and less watering when it is too hot; Potassium dihydrogen phosphate for fertilization to promote growth and development; Put it outdoors in a sunny and ventilated place.

Choose dwarf-tolerant, cold-tolerant dwarf shrubs and herbaceous plants. Because the roof garden has high temperature in summer, strong wind, poor soil moisture retention performance, and poor thermal insulation in winter, so the plants that are drought-resistant, cold-resistant are mainly selected, and at the same time, considering the special geographical environment and load-bearing requirements of the roof, attention should be paid to the selection of dwarf shrubs and herbaceous plants, in order to facilitate the transportation of plants, planting science.

Choose masculine, barren-tolerant, shallow-rooted plants. Most of the roof garden is full of direct sunlight, the light intensity is large, the plant should try to choose positive plants, but in some specific small environments, such as under the flower stand or against the wall, the sunshine time is shorter, some semi-positive plant species can be appropriately selected, in order to enrich the plant varieties of the roof garden, the planting layer of the roof is thinner, in order to prevent the erosion of the root system on the roof building structure, the shallow root system of plants should be selected as much as possible. As the application of fertilisers can affect the hygiene of the surrounding environment, roof gardens should be planted with plants that are resistant to barrenness as much as possible.

Choose plant species that are resistant to wind, lodging, and waterlogging. The wind above the roof is generally larger than the ground, especially in the rainy season or when there is a typhoon, the wind and rain are the most harmful to the survival of plants, coupled with the thin roof planting layer, the water storage performance of the soil is poor, once it rains, it is easy to cause short-term water accumulation, so we should choose some things that are wind-resistant, not easy to lodging, and can withstand short-term water accumulation at the same time.

Choose plants that are mainly evergreen and can overwinter in the open field in winter. The purpose of building a roof garden is to increase the green area of the city and beautify the "fifth façade", the plants of the roof garden should be as evergreen as possible, and the varieties of leaves and plants should be beautiful, in order to make the roof garden more colorful and colorful, reflecting the seasonal changes of the garden, some color-leaved tree species can also be planted appropriately; In addition, if conditions permit, you can arrange some potted seasonal flowers to make the garden have flowers in all seasons.

Try to choose native plants, and appropriately introduce new varieties of greening. Native plants have a high degree of adaptability to the local climate, in the relatively harsh environment of the roof garden, the selection of native plants has twice the result with half the effort, while considering that the area of the roof garden is generally small, in order to arrange it more exquisitely, you can choose to use some new varieties with higher ornamental value, so as to improve the grade of the roof garden.

The design of the roof garden must fully consider the requirements of natural conditions, and must have certain conditions, such as the requirements of solid structure, bearing capacity and water barrier, waterproof layer and drainage facilities, etc.

Buddha belly tree (Jatropha podagrica hook.).), Euphorbiaceae, a small succulent deciduous shrub of the genus Mad Tree, native to sunny tropical regions such as the West Indies of Central America. The plant height is 40-50cm, the stem is stout, the stem end is bifid and bifurcated, fleshy, the middle part is swollen, and it is ovoid and rod-shaped.
