Easy houseplants:
Coleus. Beautiful and don’t need a whole lot of light. Also, they just look pathetic if they don’t get water. Only a heartless person would let that happen.
Spider plants. Really, they have to be the EASIEST plants in all the world. Don’t need a lot of water, and a moderate amount of sunlight will do. Plus, they just look cool. If she’s got any maternal genes in her, she’ll love the little “babies” that grow.
Ficus plants are easy enough. I have a little ficus that I’ve let go with out watering for maybe a couple of weeks or even longer, and it’s still thriving. But light is key.
Phyllodendrons. Love them. And they too are forgiving if you don’t water them frequently. I have three of them hanging in my living room, and another one perched on a west-facing window sill with its “tendrils” spread across the wall. All of them are over three years old and I’ve gone through periods where I have totally neglected them.
Crotons are beautiful but need lots of water and light. I don’t think they are that hard to care for; but you can’t be forgetful about them either.
Ah, yes, SUCCULENTS! Jade plants, crassulas, and pencil plants are my favorites. They need almost no water and though they like light, they won’t shrivel up and die if they don’t get the brightest sunshine either.
Boston ferns are good too. But you’ve got to water those babies. They brown up real good if you don’t.
It’s a bit of a weirdo, but google Tillandia bulbosa. I bought one from a craft fair this May and everyone kept stopping me to ask me if it was a sculpture. It’s a beautiful epiphyte; no soil needed. You just spray it with DI water twice or three times a week.
Don’t forget Eucalyptus! Perched on the right window sill, they do quite well and they are so graceful. Plus, it will fill the home with its fragrance.
All the plants I named above co-exist with my cats, who do like to nibble on plants. I have found tricks to keep them away from my most beloved ones.
I’m a plant lover, but I’m also a flower pot enthusiast. My belief is that it’s the container that really makes someone fall in love with a gifted plant. Don’t just go to the nursery and pick out a plant. Put it in a nice colorful pot too. 'Cause maybe the plant will die, but at least she’ll still have the pot. She can use it for another plant or just use it for decoration. Two gifts in one!
