What flowers and plants are easiest to keep alive on a rooftop? Recommended plants that are suitable for growing
Today I want to introduce6types of extremely sun-tolerant, super-tough flowers that are perfect for growing on a rooftop.
Bougainvillea

Bougainvillea is also called paper flower. It comes in a rich range of varieties, from the classic green-leaf bright red to the fresh Tong'an Red and Zhangzhou Red Cherry, all of which are very popular. The more sun it gets, the more it blooms, and the red, pink and purple flowers cascade down like a waterfall, a spectacular sight. Care is extremely simple: use a loose, airy sandy soil, water it2-3times a week during the growing season, apply potassium dihydrogen phosphate once a week before the flowering period, and promptly prune off spent flowers and leggy shoots after flowering, and it will burst into bloom again very soon!
Crape Myrtle

Crape myrtle has smooth bark and twisted branches, and is also known as the "tickle tree" because it sways at the slightest touch of its branches. The flowers are elegant, borne in terminal panicles, and when in bloom the whole tree is covered in blossoms. Just water thoroughly as usual and keep the soil slightly moist; apply organic fertilizer once every early spring, then top up with a little compound fertilizer during the flowering period. Watch out for aphids, and a spray of soapy water will take care of them once you spot them.
Moss Rose

Moss rose is also called large-flowered purslane. It is extremely tough, and is said to "live as soon as it touches soil." Use ordinary garden soil+river sand mixed together, water once a day, and feed lightly and often (compound fertilizer once every half month). Double-petaled varieties produce a lot of flowers, so remember to prune off spent blooms after flowering and they will bloom another round!
Jasmine

Jasmine flowers are pure white and elegant, with a rich fragrance. Give it at least6hours of light a day, and water only when the soil dries out to a pale color. During the growing season, water once a week with alum fertilizer water to improve the soil's pH, and after the flowers fade, prune down to2pairs of leaves, and new shoots will soon appear.
Mandevilla

Mandevilla is also called the double-happiness vine, and its flowers look like little trumpets in brilliant colors. Grow it in peat soil+perlite, and keep the potting soil moist but not waterlogged. Apply a slow-release fertilizer once a month, cut off spent flowers and weak, spindly branches after flowering, and when the temperature drops below10°C move it indoors, and it will keep blooming again next year!
Plumbago

Plumbago has slender branches, and its flowers grow in spherical clusters, with blue-purple tones that feel especially cooling in summer. Grow it in general-purpose potting soil, water once in the morning and once in the evening each day to avoid dehydration. During the vigorous growing season, apply Flower Duoduo2once a month, and after flowering prune the branches back hard, and it will quickly grow into a big ball of flowers again!
These6kinds of flowers are not only beautiful but also easy to care for, so even complete beginners can master them with ease.
