I just got 2 pitcher plants, I'm not sure what the exact name is, but it is in a hanging basket, with all green leaves and the pitchers are redish on the top half and green on the bottom half. The mature pitchers are about 4 inches long (give or take an inch)

I was told that these plants like humidity, and also that I'm supposed to keep about a quarter inch of water in the pitchers at all times, and to keep the soil moist.

Also, when I brought them home, I noticed some black spots of mold/ mildew on the stems, leaves and pitchers. I wiped some of it off with a wet q-tip, then I called the store that I bought them from and they said they would give me a free bottle of silver solution spray to kill mold and mildew on plants. So I sprayed the plant and it seems to work.

My questions are:

How long do te pitchers last?

Do these plants produce pitchers year round?

How can I encourage it to veep producing pitchers as thenoldnones die?

I'm kind of worried about this plant because in the winter my house is not humid at all because of the heater. And it also gets pretty cold in the house at night.

Any suggestions?
