All houseplants have certain requirements. Finding the right plants for your indoor conditions is the key. Houseplants may need low, medium or high amounts of sunlight. Choose the ones suited for the desired location. If the plant does not do well there, try another location until it responds. Once the plant is happy, leave it alone. The easiest plants are those that adapt to a broader range of light and temperature conditions.
One of the largest family of houseplants are philodendrons. They come in varieties with very large leaves, finely cut leaves, heart shaped leaves, and even variegated forms. This plant handles filtered light well but may not thrive in complete shade. It is just as happy in full sun. It is the easiest house plant to propagate. Snap the stem at a joint where aerial rootlets have already formed. Drop the stem into a jar of water. Change the water weekly, and wait for roots. The best way to create an entirely new plant is to use three of these cuttings to a container. Philodendrons are a hanging, vining plant. They also can be trained up a container trellis to be used as an upright plant. Philodendrons are one of the fastest growing houseplants.
Peace lily, spathiphyllum, will bloom reliably indoors once a year. There is a large-leaf variety, and one with smaller leaves. The large one will need much more space, so plan accordingly. The leaves are deep green, glossy and strap-like. This plant prefers high light and more water than most other houseplants. Given these requirements, it is easy to grow. If it becomes wilted, give it water and it will recover. Trim away any brown leaves to keep it tidy. Peace Lily will produce little plantlets that can be repotted to create more plants.
Most of the taller houseplants found fall into the draecena group. They have skinny leaves arranged around a slender stem or stalk. They develop a palm like appearance as they lose their lower leaves and mature. Many will produce multiple stems over time. The most common colors are green with yellow or cream margins and pink or red edging. Draecenas like medium light and average water. If the leaves turn brown on the tips, reduce the water. Most draecenas are from arid regions, so do not over water. The brown leaves can be trimmed off, and new ones will replace them. Some of this can be part of the plants' yearly cycle. It is easier to buy plant starts, than to propagate draecena.
The African violet, Saintpaulia, needs the right light for consistent bloom. Place the plant on a windowsill or in front of a window that receives good morning light. It may burn in afternoon sun. If late sun is all that is available, place it back from the window so it will receive indirect sunlight. To water, take plants to the sink and allow water to run through the containers. This will keep fertilizer salts from building up. If six months go by without flowers, change the location. Once they receive just the right amount of light, they will bloom on and off all year long. Sometimes they produce off-spring that can be transplanted. African violets can be propagated by leaf cuttings. Place foil over a small jar and dangle the stem in water without submerging the whole leaf. A little plant will grow above the water surface.
