Poinsettia Euphorbia pulcherrima 'Autumn Leaves'
ABOUT
Autumn Leaves is a striking variety of the widely recognized holiday plant, commonly known as the poinsettia. This particular cultivar is known for its distinctive bracts, which are the showy, leaf-like parts that many people mistakenly believe are the plant's flowers. The bracts of Autumn Leaves transition from green to a beautiful mix of colors that resemble the hues of fall foliage. They start out green and as they mature, they change to a warm blend of cream, yellow, and soft pink tones. In the center of the whorl of bracts, you'll find the true flowers, which are small and yellowish, not particularly showy, and clustered in the middle. These are called cyathia. The plant itself has dark green leaves that contrast nicely with the lighter colored bracts, making the Autumn Leaves variety stand out. The overall impression is one of a mellow autumnal display, hence the name 'Autumn Leaves'. It's favored for its unique coloration, which offers an alternative to the more traditional solid red or white poinsettia varieties that are commonly seen during the holiday season. The Autumn Leaves poinsettia lends itself well to festive décor, particularly in settings that aim for a less conventional holiday color palette.

- Toxicity
To humans
The common name for Euphorbia pulcherrima 'Autumn Leaves' is Poinsettia. Poinsettias are generally considered to have a low toxicity for humans. However, if ingested, the plant's sap may cause mild irritation to the mouth and stomach, possibly leading to nausea and vomiting. Contact with the skin can result in irritation, redness, and swelling. If the sap comes in contact with the eyes, it may cause pain and temporary vision blurring.
To pets
The common name for Euphorbia pulcherrima 'Autumn Leaves' is Poinsettia. Poinsettias are also known to be toxic to pets, particularly cats and dogs. If a pet ingests the plant, the most common symptoms may include nausea, vomiting, and sometimes diarrhea. The milky white sap contains chemicals known as diterpenoid euphorbol esters and saponin-like detergents, which can cause irritation in the mouth and stomach of the animal leading to the symptoms mentioned. While toxicity is generally considered mild, it is advisable to keep poinsettias out of reach of pets and monitor them for any signs of distress after coming into contact with the plant.

- Water
Poinsettias require even moisture and should not be allowed to dry out entirely, nor should they be left in standing water. Water this variety when the top inch of the soil feels dry to the touch, approximately once a week, with about 12-16 ounces of water. During winter, reduce watering frequency as the plant goes into dormancy and growth slows down. Ensure good drainage to prevent root rot, and avoid splashing the leaves to prevent fungal diseases. In high humidity, you may need to water less frequently.
- Light
Poinsettias perform best in bright, indirect sunlight, such as near a south or east-facing window. These plants need about 6-8 hours of daylight daily. Direct sunlight can scorch the leaves, so make sure to filter intense sun through a sheer curtain or place the plant in partial shade.
- Temperature
Poinsettias prefer temperatures between 60 - 70°F during the day and not below 50°F at night. They can tolerate a range between 50 - 70°F, but prolonged exposure to temperatures outside of this range can cause damage. The ideal condition is a consistent temperature, avoiding drafts, sudden temperature changes, or exposure to extreme heat or cold.
- Pruning
Prune poinsettias to maintain their shape and encourage bushier growth. Trim back the plant in spring, after the blooming period has finished, removing about one-third of the plant. Pruning can be done again in mid-summer to keep the plant compact. Pruning is essential to prompt the plant to develop more branches, which leads to more blooms during the holiday season.
- Cleaning
As needed
- Soil
Poinsettias require well-draining soil with a slightly acidic to neutral pH range of 6.0 to 7.0. A good soil mix for poinsettias like 'Autumn Leaves' can be made using one part peat moss, one part perlite, and one part potting soil to ensure adequate drainage and aeration.
- Repotting
Poinsettias like 'Autumn Leaves' should be repotted every 1 to 2 years to replenish soil nutrients and to accommodate root growth. It is best to repot them in spring after the blooming season.
- Humidity & Misting
Poinsettias like 'Autumn Leaves' prefer a humidity level of around 40-60%. They thrive in environments that aren't too dry but should be protected from excess moisture to prevent leaf drop.
- Suitable locations
Indoor
Place poinsettias in bright, indirect light and away from drafts.
Outdoor
Grow in sheltered areas with indirect light and no frost.
Hardiness zone
9-11 USDA
- Life cycle
Euphorbia pulcherrima 'Autumn Leaves', commonly known as Poinsettia, begins its life cycle from seeds or cuttings, with seedlings or rooted cuttings being potted for growth. After potting, the plant enters a growth phase where leaves and stems develop rapidly under the right conditions of warmth and light. As the plant matures, it requires a period of darkness (about 14 hours per night for at least six weeks) to initiate the development of its characteristic colorful bracts, which is a critical stage in its life cycle known as photoperiodism. Following the bract coloration, the Poinsettia comes into full bloom, showcasing its vibrant autumnal leaves which are actually modified leaves called bracts, while the actual flowers are the small, yellow clusters in the center called cyathia. After the blooming period, the Poinsettia enters a dormancy stage, where leaves may drop and the plant requires less water. With proper care, the plant can be induced to rebloom in subsequent years, completing its perennial life cycle.
- Propogation
Propogation time
Early summer
The most popular method of propagating Poinsettia 'Autumn Leaves', or indeed any poinsettia, is through cuttings. This typically takes place in late spring to early summer, when the plant is actively growing. The process involves cutting a stem from the mother plant, approximately 4 to 6 inches (10 to 15 centimeters) in length, ensuring that there are several leaves on the cutting. The lower leaves are removed, and the cut end is dipped in rooting hormone to encourage root growth. The cutting is then placed in a well-draining soil mix and kept consistently moist but not overly wet. It's important to provide a high humidity environment for the cutting by covering it with a plastic bag or placing it in a propagator, and kept under indirect light until roots have developed, usually within several weeks. Once the roots are established, the new poinsettia plant can be transplanted into a larger pot and gradually acclimated to less humid conditions.
