A couple years is how long poinsettias (Euphorbia pulcherrima) can grow.
Specifically, poinsettias are perennial shrubs in their native southwest Mexican and Central American homelands. Outside that native range, they tend to be grown as annuals whose life and death take place over the course of a year. But they have the potential to live much longer, if such critical conditions as appropriate levels of heat, light intensity and moisture are met.
Poinsettias originate from Mexico.
Thank you for watering my poinsettias.
Poinsettias typically stay red and vibrant for about 4-6 weeks during the holiday season with proper care.
Poinsettias have fibrous roots that can spread as far as they need to.
Yes, poinsettias are considered short-day plants, meaning they require long periods of uninterrupted darkness to induce flowering. This darkness prompts the plant to initiate its colorful bracts.

poinsettias
From Mexico
Plants requiring long nights to flower are called short-day plants. These plants use the length of darkness as a cue to initiate flowering. Examples include poinsettias, chrysanthemums, and strawberries.
Twelve (12) hours 20 minutes of uninterrupted darkness for five (5) days straight is the amount of darkness that poinsettias (Euphorbia pulcherrima) needs in order to bloom.Specifically, that is the requirement that must be met sometime between September 20 and October 20 in order for poinsettias to bloom in December. Such is the natural bloom cycle for poinsettias as long as other critical conditions such as air and soil moisture, light intensity, nutrition and temperature are met. But in fact, anytime that poinsettias undergo the above-mentioned short day/long night cycle they have the potential to see the flowering process initiated and their modified leaves change in color from green to red 65-85 days later.
Poinsettias are called flores de nochebuena because they are flowers that are beautiful at night.
