This flower blooms for 100 days straight, blooms more wildly the hotter it gets, and can be grown just by sticking a cutting in soil

Morning glories are very common and very beautiful, and many people grew them as children, but not everyone has grown petunias. Petunias are annual or biennial herbaceous plants. Although they are ordinary flowers, they are heat-tolerant, sun-tolerant, tough and easy to grow, and their flowering period is amazingly long, from spring to autumn.
Double-flowered petunias are especially beautiful, and there are also flowers with edges in all kinds of colors. The petals are purple, white, and all kinds of red, and they look beautiful no matter how you look at them. The blooms are gorgeous and bold, and a single plant can open dozens or even hundreds of flowers at the same time. Grow one pot on a balcony or terrace, and it can even grow into a flower ball several tens of cm in diameter. Petunias are very easy to care for:
1. Propagation is especially simple. You can sow seeds directly. Although the seeds are rather small, sowing is also very easy and they sprout readily, sprouting in about ten days.
2. There is another even simpler planting method, which is to simply pinch off some branches and stick them as cuttings into a flower pot or sandy soil, keeping the medium moist and shaded without direct sun.
You can also put a plastic bag over it to cover it with a layer of film, keeping it moist and shaded, and it will grow roots in ten days. Once five new leaves have grown, it can be transplanted into a pot.
3. When caring for petunias normally, do not keep them in a place with insufficient light for a long time, as they easily become leggy. In fact, they are not afraid of sun; the stronger the light, the better they grow and the more they bloom.
4. During the growing season, pinch and prune the petunias whenever you have time, that is, pinch off the top two leaves or so at the very highest tip. This allows more side branches to grow and produces double the flowers.
5. Be sure to fertilize often. Any fertilizer containing phosphorus and potassium will do, and fermented chicken manure or cake fertilizer also works, once a week.
6. After it has bloomed once, promptly prune off the spent flowers; do not be reluctant to do it. Prune hard once a month, and in less than ten days or so it will be full of buds again and cover the whole pot with blooms.
7. Prune more. After blooming, all the spent flowers and withered leaves must be cut off completely. Prune hard once every month, and in less than half a month the flowers will fill the pot again.
