Which flowers grow longer and longer as the weather gets colder and bloom bigger?

Petunia Petunia loves a humid and cold living environment. Petunias don't bloom well in summer. Afraid of watering too much, afraid of rain, afraid of exposure. Several pots of petunias I planted myself died in summer, just because of the rain. And the long branches are too long, and dead leaves appear at the bottom, like a piece of wheat straw. I'm going to start with a few seedlings, just like I started with a few pots of Petunia last autumn, and it became a big pot in a month or two. I can prepare some flowering seedlings in autumn, like Petunia cuttings. They are all bought in autumn. Don't let it blossom after you buy it. Cut off his bud first and continue to dig his heart. First, let it grow plants. When it blooms in spring, it will be particularly plump and the roots will be strong, and the flowering will definitely burst. Petunia cuttings, which began in spring, usually don't bloom for the first time, and the flower quantity can't be compared with autumn seedlings. And in summer, because the root system is not strong, it is easy to die.

Secondly, Margaret, as soon as she blooms, will keep blooming, which can be cultivated by both beginners and experts. It is a flower full of creativity. Margaret, like Penny, likes wet and cold living environment and is afraid of persistent high temperature and high fever. Therefore, when you buy seedlings in autumn, you'd better prune and manage them after you buy them, and then you can bloom in autumn. In winter, the flowering period in areas above 10 will last until next spring and summer. When the roots are cultivated, they will grow sturdily and spend a lot of money. Margaret seedlings can be cut by themselves, and the cut seedlings will have stronger flowering characteristics than those piled downhill.

Thirdly, Platycodon grandiflorum is a very famous flower of Ophiopogon japonicus in Phnom Penh, Gentianaceae. Its stem is tall and beautiful. Full of fairy flavor, fresh and elegant, nature can also be potted. A potted plant can produce dozens of eustoma grandiflorum. Several kinds of eustoma grandiflorum are really beautiful together. Eustoma grandiflorum is also relatively simple to maintain. In spring and autumn, the soil layer is loose and breathable, with more sunshine and good growth. But it is also afraid of high temperature. In winter above 0 degrees, you can move indoors to keep warm. Eustoma grandiflorum is more beautiful than roses and jasmine, full of fairy spirit. One branch with many colors can open 10~20 bundles. Generally, one branch represents 5~ 10 flowers. The growth temperature of eustoma grandiflorum is between15℃ and 25℃, and it needs a period of ultra-low temperature to maintain its full flowering period. The seedlings that start in autumn just make it grow and develop in spring, and the plants are strong, which will be even more shocking when they bloom next year. If it can be well maintained, it may bloom all year round.
