No flower says happy holidays like a poinsettia.
From traditional red to pink, ivory, lime green, burgundy and even blue, poinsettias bring color to indoor decorating.
Your poinsettia will perform best if kept moist in a bright place and grouped with other plants to increase group humidity. Keep the plants away from a heating vent that will dry them out.
If they come with a foil wrapper around the pot, either punch holes in the bottom or tear it off. If you don't, the plant roots may drown as you overwater it.
If you want to save your plant after the holidays, continue to care for it. You can bring it outside for the summer in dappled shade. When fall approaches, bring it inside and place it in a sunny window in a room you never go into after sundown. The reason for this is that poinsettias bloom in response to the shortening of days. If it gets supplemental light after sunset, it will throw of this cycle and prevent it from re-blooming.
Even porch lights and street lights shining in through the window can interfere with its blooming.
Other seasonal plants can accompany your poinsettia.
Cyclamens, hydrangeas and foliage plants such as boxwood, Norfolk Island pine and ivy make good companions. Cyclamens are great for "sweater people" who keep their homes cool.
They thrive on cool windowsills. Boxwood are hardy outdoors in Colorado but are a little touchy. Topiary forms--such as those sheared into Christmas tree shape--can be enjoyed outside in summer and indoors in winter in bright rooms. Norfolk Island pines are not hardy here but make good houseplants if they have enough humidity.
Poinsettias will look best and perform best when grouped with other plants.
Make your display colorful and pay attention to using contrasting shapes and textures. With bright light, moist soil and protection from dry air, your plants will last well beyond the holidays.
