Some ferns are popular as houseplants.

Houseplant culture is a unique type of horticulture. It involves almost no gardening. Most houseplants live exclusively indoors. Many inhabit homes and offices that lack gardens. Only a few fortunate sorts get to occasionally enjoy mild weather in home gardens. Such indulgences are generally brief and sheltered. Most houseplants are innately vulnerable. 

Of course, no houseplant is native to domestic situations. Every houseplant lives outside somewhere. Most are from lush tropical rain forests, where they must compete with other foliage for sunlight. Many are understory plants that naturally live within the partial shade of bigger tropical vegetation. That is why they adapt so efficiently to partial shade inside.

That is also why most houseplants actually want to live inside here. They do not like the chill of winter, even if mild. Many or most succumb to minor frost if too exposed. They are simply unaccustomed to it. Since they adapt to shelter and partial shade inside, they are also sensitive to direct sunlight exposure. Foliage that becomes too exposed can scorch. 

Tolerance of weather is as regional for houseplants as it is for garden plants. That is one commonality of gardening and houseplant culture. The various species of Ficus that are common trees in landscapes of Los Angeles are strictly houseplants in San Jose. They tolerate the minor winter chill of Los Angeles, but not the slightly cooler frost of San Jose. 

Some ferns are popular houseplants because, like tropical plants, they generally tolerate partial shade. However, many are less tolerant of the minimal humidity of home interiors. Regular watering can compensate. Irregular watering might be distressful for some ferns. Fortunately, most ferns can recover from brief desiccation, even if their foliage dies back.

Succulents are completely different. The are intolerant of partial shade, and crave sunny and warm situations. They are nonetheless popular for houseplant culture because they generally tolerate minimal humidity. Cacti prefer aridity, and are very susceptible to rot in damp conditions. Succulents wilt to warn before they succumb to deficiency of moisture.

    1. That is normal, but in the mildest climates, they do not need to be brought in. Most of my houseplants were landscape stock that I brought from Los Angeles County. I will be going to the Los Angeles region in a few months, so may bring a few more back.
