Look for a full plant with dark green leaves and brightly colored bracts. Examine the true flowers, which are the small, round yellow parts in the center of the bracts. If they are tightly closed, it is an indicator that the plant is fresh. As the plant ages, the true flowers will open. Avoid plants that are wilted, that have faded bracts, or have lost their leaves. These plants have received improper care and will not be long lasting.

When purchasing the plant, be sure to have the store clerk wrap the plant in a paper sleeve or bag. Poinsettias are tropical plants and are subject to chilling injury at temperatures below 50°F. Do not leave the plant in a cold car while shopping, or carry it home in the trunk.

Poinsettias must be cared for properly to insure that they flower well for a long time. Water so that the planting mix is consistently moist. Do not let the soil become soggy or overly dry as this will stress the plant and decrease flowering time. A plant that has its pot wrapped in decorative foil is at risk for over-watering. Punch holes in the foil to let water drain through. Do not let the poinsettia sit in a saucer full of water.

Keep the plant in a cool room (65-70°F) during the day and drop the night temperatures another 5 degrees if possible. This will help to extend the flowering time. Place the plant where it will not be affected by hot or cold drafts.

Give the plant good light. Bright, indirect light is ideal. The plant can be placed in direct sunlight but this may increase its water needs. North facing windows get very little light and should be avoided.
