Is bellflower a perennial or an annual, is it toxic, and can you keep it at home if you have a cat?
Is bellflower toxic to cats? According to the ASPCA, bellflower is non-toxic to cats, as long as the cat does not eat it. Although bellflower tends to breed bacteria when soaked in water, it has no direct toxicity to cats themselves.

Bellflower belongs to the Campanulaceae family and is generally grown as an annual, biennial or perennial herbaceous flowering plant. In seasons with suitable temperatures, bellflower grows particularly well, especially between 12 and 18 degrees; bellflower is quite sensitive to temperature, and above 30 degrees the leaves turn yellow and the plant wilts; in winter, if the temperature drops below 2 degrees, it stops growing and the leaves turn yellow and withered, and if it is not moved to a warm place in time, it will freeze to death.
Bellflower's flowers are cute and small, bell-shaped, usually blue, and it is suitable for container growing as well as being grown as a garden plant. However, growing bellflower well is not easy; it is a plant that likes mild, cool conditions and dreads heat most of all. When summer temperatures rise above 30 degrees, the leaves easily turn yellow and the plant easily picks up diseases.

1. Growing environment
Bellflower plants need to grow in a cool environment to do well, but its seeds need a warm environment to germinate well, and the best sowing temperature is between 18 and 22 degrees.
2. Watering and fertilizing
In the daily care of bellflower, be sure to choose a loose, airy potting soil with good drainage. It does not demand much from soil fertility, but the soil drainage must be good. It can tolerate moderate drought, but it particularly fears too much water; once the soil is constantly wet, the roots and stems easily rot, and it also easily attracts pathogens (such as anthracnose or rust).
3. Light and pinching
Once a potted bellflower is growing vigorously, give it more light. Bellflower only grows strong in a spot with plenty of sunlight, and it needs at least 8 hours of light a day to grow vigorously. The longer the light it receives each day, the better it is for bellflower to bloom; this is what makes it a "long-day plant."
When the bellflower plant reaches 18 cm tall, you can start pinching off the tips. Continual pinching promotes branching and also controls plant height, which is certainly very beneficial to its growth.
Fun flower lore
There was once a hard-luck couple: the husband was a blind man who made a living telling fortunes, while the wife earned a living by weaving. The wife hung a bell to help her husband find his way, and they loved each other. The husband went out and met with disaster and went missing, and the wife kept watch for many years. After a merchant brought news, the wife disappeared and turned into a bellflower. In the village, bellflower is used to convey love, representing eternal waiting and a devoted promise. Whoever receives a bellflower will be granted happiness.
