White houseplants can work wonderfully to accent a decorating scheme or to add to a specific feeling you want to have in your home. There are several species of houseplants with specific varieties that produce white flowers exclusively. Most of these plants have varieties that produce colors other than white, so you will need to be careful about which varieties you purchase.
The gardenia plant produces large and exceptionally fragrant white flowers that resemble those used in corsages. It can grow rather large for a houseplant (2 to 6 feet), and requires a lot of sun. Gardenias should be watered regularly.
The peace lily is a widely available houseplant, and produces white flowers with a rather distinctive appearance. The plants do well with fairly moist soil and low to medium light. Peace lilies are adaptable to widely varying conditions and are easy to care for, making them good for beginning indoor gardeners.
The Phalaenopsis orchid variety requires a lot of light, but not a lot of water. Water when the soil has dried out. The plant produces large, beautiful flowers and attractive leaves. It blooms annually for three to six months. You can encourage them to bloom more during this period by reducing the temperature they are exposed to by 10 to 15 degrees F at night.
Asparagus setaceus, often called the asparagus fern, produces small, white flowers. It will grow multiple stems and produce many small needles, resembling both its namesakes (asparagus and fern). Asparagus ferns require a lot of sun, but should only be watered once the soil has dried.
White Pearl Hyacinth
The hyacinth is grown from a bulb and produces unusual but enchanting white flowers. These grow from a stalk in the center of the plant, forming something of a cylinder of flowers. They require a lot of sun and bloom in the spring.
The wax begonia produces small numbers of large, waxy leaves and medium-sized flowers. One big advantage to these plants is that they bloom year-round. They require a good amount of sunlight, but only need to be watered when the soil is dry.
