Don't keep these flowers and plants in summer, lest they affect your health

The hot summer has arrived, and many gardening friends are wondering what kind of flowers and plants they should grow in summer. But before growing flowers and plants, you need to understand the living habits of some plants. Some flowers and plants are simply not suitable for growing in summer. Here is an introduction for everyone.
Iris
Iris is known as the "blue enchantress". Its leaves are emerald green and glossy, and it blooms blue flowers that give off a rich fragrance. After blooming, it looks like a blue butterfly dancing gracefully in a green forest, and it has high ornamental value. But its flowering period is short, and it is suited to growing in low-temperature environments, so it is not suitable for growing in summer.
Hydrangea
Hydrangea flowers are large and gorgeous, come in many colors, and have high ornamental value. Although hydrangea is pleasing to look at, the tiny particles it releases can cause allergic reactions in people. And when summer temperatures are too high and air circulation is poor, it is even easier to trigger allergies, so it is best not to keep hydrangea at home in summer.
Campanula (Canterbury bells)
Campanula has a rather unusual flower shape, resembling little bells, and its flower colors are fairly fresh. As a light breeze blows past, it is like a bell that gives off sound, so it is deeply loved by everyone. But campanula is especially good at attracting bees in summer. If you keep it at home, you will surely be attacked by bees every few days, so try not to choose campanula for growing in summer.
Ranunculus (Persian buttercup)
Ranunculus has a graceful plant shape and blooms rather gorgeous flowers in many colors. Its flower shape is very similar to that of the peony, which is why people call it "foreign peony". Although ranunculus has high ornamental value, its flowering period is in winter, not summer, so it is best not to grow it in summer.
