What flowers are suitable for planting on the roof?

As a roof garden, we must first solve the problems of leakage prevention, water supply and drainage, roof bearing and so on.

Tree species selection should consider sun protection, wind protection and easy management. Generally trees don't grow tall easily.

Lagerstroemia indica, Phyllostachys pubescens, cycads, dwarf peaches and Podocarpus can be used as the skeleton, and nightshade, plumeria, Lagerstroemia speciosa and Australian duck feet can also be used in the southern region. Then I use middle and high-grade plants to make up the meat. Because I don't know where you are, I will use plants in tropical and subtropical areas such as safflower, colored iron, lantana, azalea, red velvet ball, sunflower, anchovy, spring feather, gardenia, nandina, dragon boat, bamboo banana, thin-leaf cigar, golden banyan and so on. Then the ground is covered with skin, which can be Sedum sarmentosum, Zoysia japonica, Ophiopogon japonicus and leek. In short, high, medium and low varieties, different colors can be used.
