What are the three best houseplants that everyone should own and why?

I tell people to go sit in Woodfield Mall and look at what’s doing well. We like to sell what will grow, what’s easy. So there’s ZZ plant (Zamioculcas zamifolia). It will survive if you go away for a 2-3 week vacation. Needs little water. Chinese evergreen (Aglaonema) is a wonderful plant. Will grow in any light; also doesn’t take much water. And pothos (Epipremnum aureum). We like to keep it simple.

Mother-in-law’s tongue (Sansevieria trifasciata) is one of the easiest plants to maintain. Find a place with dim light or low sun and forget it. The plant just needs a drink of water every 2-3 weeks.
Peace lily (Spathyphyllum). This is a phenomenal plant.Very easy to maintain. Will thrive in filtered sun but will do equally well in dim light. This plant loves moist soil.
Spider plant (Chlorophytum comosum) is a plant that keeps on giving. Very easy to take care of, it will often send out feelers with a baby spider plant attached. Just pop the baby in a pot of soil, allow roots to form and cut it free from the mother plant.

People think orchids are difficult to grow because they look exotic, but the Phalaenopsis orchid is easy to grow. The blooms are elegant and can last up to three months.
Spider plants (Chlorophytum comosum) adapt well to most places in your home and are one of the easiest plants there are. They are forgiving if neglected, and they also improve the air quality in your home.
FIddleleaf fig (Ficus lyrata) is a trendy plant. It’s easy to grow and adds character to a room. It can get tall but that’s what makes it blend in nicely with your décor.

For high-light situations I like variegated Swedish ivy (Plectranthus madagascariensis). This trailing vine is so much fun with its vibrant white margin and aromatic scent. It prefers moist well-drained soil.
For medium light, I suggest mistletoe cactus (Rhipsalis pilocarpa). This is a cool trailing non-toxic succulent type plant that never likes to dry out. It is also not very sharp to the touch like other cacti. It prefer moist, well-drained soil.
For low light, I recommend snake plant (Sansevieria trifasciata). It’s very easy to care for as long as you let it slightly dry out between waterings. It’s very striking with its color and stiff upright habit.
I have houseplants outside that I will need to bring indoors. What is the lowest temperature at which I can leave them outside?
What is the green worm that eats my roses and columbine every year?
What does it take to make a climbing hydrangea flower? Ours was planted 3 years ago and is growing energetically. It’s in a protected nook near the patio and gets very little direct sunlight, but doesn’t act sun starved. We gave it a shot of slow release fertilizer on planting, and once since. Somewhat inadvertently it gets plenty of water, since the hose spigot is nearby and leaks, but drainage does not seem to be the problem. It now fully occupies an 8-foot trellis but shows no interest in flowering. Is it youth, lack of sun, too much or too little fertilizer, bugs, lack of pruning or what? When do these plants bloom and what conditions do they like?
