Which flowers are not suitable for planting in winter?

Today, I will introduce gardenia, Nostoc flagelliforme, Phyllostachys pubescens, Cymbidium hybridum and Phalaenopsis, which are not suitable for indoor breeding in winter.

Because gardenias are very common in winter flower markets, they all have buds, and even one is half-open. When you walk to the edge, you can smell very fragrant. Generally, people who buy it go for its beauty and fragrance, but this kind of flower is artificially introduced in the greenhouse, because spring is the normal flowering period. If you buy it back, it is easy to have problems when you buy it home. First of all, most of the flowers bought at the flower market are cultivated in garden soil. After buying it, you can't exchange flowers for pots, and the garden soil at home is easy to deposit and harden, so it is difficult to raise it well. If you want to buy it, wait until the temperature warms up in spring, and you can open the window for ventilation. When you buy it again, watering and fertilizing can ensure that it blooms. It is not easy to change pots after flowers are spent, because everyone who has bought this kind of flowers knows that most of them are yellow leaves and rotten leaves, and only poles can save them.
