Euphorbia pulcherrima is a warm-climate plant that can stay attractive well beyond the holidays. Give it bright light, stable warmth, and soil that is moist but never waterlogged. The red, pink, cream, and other showy parts are bracts (modified leaves), while the tiny yellow cyathia in their centers are the flowers. Poinsettias are not considered deadly if eaten, but chewing the plant or contacting its sap can cause irritation, so sensible household precautions still matter.
What a poinsettia is—and what the “flowers” really are
Poinsettia is the common name for Euphorbia pulcherrima, a species native to Mexico in the Euphorbia family. Its intense color is part of a winter-day response: shorter days trigger color development in the upper leaves. Cultivars can produce red, pink, cream, and other bract colors.

Bracts are the showy leaves
The large colored structures are modified leaves called bracts, not petals. Their job is to surround and draw attention to the plant’s reproductive structures. The small yellow structures at the center of each cluster are the true flowers, called cyathia. When choosing a plant, look for cyathia that are still present and fresh rather than already shed; that generally indicates the display has more time left.
How to choose a healthy poinsettia
Plant quality at purchase determines how easily it survives the trip home and adapts to indoor conditions. Penn State Extension recommends a balanced, full plant with healthy foliage.
#1 Best Overall
- GROWING REQUIREMENTS: These Poinsettia seeds thrive in well-draining soil with temperatures between 60-70°F, requiring bright indirect sunlight for optimal growth
- PACKAGE CONTENTS: Set of 20 premium quality Poinsettia seeds capable of growing into vibrant red holiday plants with deep green foliage
- MATURE SIZE: When fully grown, plants can reach heights of 2-3 feet tall and spread 1-2 feet wide in proper indoor growing conditions
- BLOOMING SEASON: Plants typically flower during winter months, producing striking red bracts that create the classic holiday appearance
- PLANTING INSTRUCTIONS: Sow seeds 1/4 inch deep in moistened potting mix, maintain consistent soil moisture, and expect germination within 14-21 days
- Inspect both sides of the leaves and the points where leaves meet stems for insects.
- Reject plants with wilted, damaged, or missing leaves.
- Avoid pots with soil that is extremely dry or saturated.
- Check that stems are sturdy and the plant is evenly branched rather than sparse on one side.
- Ask for the plant to be protected from cold during transport. Even brief exposure to low temperatures can damage leaves and bracts.
Keep the plant wrapped during the journey and take it directly to its indoor location. Do not leave it in an unheated car, porch, or entryway while running errands.
Indoor poinsettia care: light, temperature, and placement
Give it bright natural light
Place the pot near a bright south-, east-, or west-facing window. Bright light helps the plant retain foliage and supports the color display. A window with strong drafts is not a good location, however; move the plant far enough from the glass to avoid cold exposure.
Keep temperatures stable
University of Minnesota Extension identifies 65–70°F as ideal indoors and warns that temperatures below 50°F can damage poinsettias. Penn State gives a similar daytime range, with nights around 55–65°F. Both sources caution against drafts and abrupt temperature changes, which can trigger leaf and flower drop. Freezing temperatures kill poinsettias.
| Condition | University of Minnesota Extension | Penn State Extension |
|---|---|---|
| Preferred daytime temperature | 65–70°F | 65–70°F |
| Night guidance | Not separately stated | 55–65°F |
| Cold warning | Below 50°F can cause damage; freezing kills the plant | Avoid temperatures below 50°F |
These are extension recommendations for household care, not universal laboratory cutoffs. Keep the plant away from exterior doors, frequently opened windows, heat ducts, fireplaces, fans, and space heaters. Those sites can expose it to cold blasts, drying air, or rapid swings even when the room’s average temperature seems comfortable.
How often should you water a poinsettia?
Water by checking the plant rather than following a fixed calendar. When the soil surface feels dry to a light touch or the pot feels noticeably lightweight, water thoroughly. Do not wait for the plant to wilt.

- Remove the poinsettia from decorative foil or an outer cachepot before watering.
- Use a container with unobstructed drainage holes.
- Pour water over the soil until it runs freely from the holes.
- Let the pot drain completely.
- Empty any saucer or outer container before returning the plant to its display location.
The goal is evenly moist soil, not a permanently wet root ball. Water standing around the roots limits air and can lead to root rot. Penn State likewise recommends watering when the soil feels dry, allowing water to pass through the drainage holes, and never leaving the pot in a water-filled saucer. A foil sleeve that traps runoff is a common cause of accidental overwatering, so always check beneath it.
Fertilizer and repotting after the holiday display
When to fertilize
A poinsettia bought in flower does not need fertilizer during the holiday display. University of Minnesota Extension recommends beginning when new growth appears. Use an all-purpose houseplant fertilizer at half the label’s stated strength every three to four weeks.
When and how to repot
For a late-spring or early-summer transplant, choose a pot about 2–4 inches larger than the current container and make sure it drains well. A much larger pot holds excess wet soil around a small root system, so increasing only one or two container sizes is the safer approach. Water the plant normally after repotting and keep it in its bright, stable location while it settles.
Can poinsettias grow outside?
They can spend part of the year outdoors in a suitable season, but the care guidance available here does not establish one universal outdoor climate range or a year-round hardiness zone. University of Minnesota Extension’s annual schedule moves the plant outdoors in summer and brings it back inside in September. That seasonal instruction should not be read as permission to expose a poinsettia to frost or cold nights.
Before moving it outside, wait for reliably warm weather and choose a protected site consistent with local extension advice. Watch overnight temperatures closely; the indoor threshold of 50°F is a useful warning level from both University of Minnesota and Penn State guidance. Bring the plant indoors before cool autumn weather arrives, rather than waiting for visible damage.

Are poinsettias poisonous to people or pets?
Poison Control states that poinsettia is not fatal if eaten. Its article summarizes the common myth plainly: “The poinsettia plant is often considered deadly. That’s wrong.” That does not mean the plant is completely harmless. Eating plant material can cause mouth irritation, nausea, vomiting, or diarrhea, and the milky sap can cause a skin rash. Leaves and stems can also present a choking hazard for young children and animals.
Practical safety steps
- Place the pot where children and pets cannot chew the leaves or knock the container over.
- Wash hands after pruning or handling broken stems, especially if sap has contacted your skin.
- Do not deliberately taste the plant or use its leaves in food or crafts.
- Keep fallen leaves and dropped bracts picked up from floors accessible to pets.
For an actual exposure in the United States, use Poison Control’s webPOISONCONTROL tool or call 1-800-222-1222. Seek immediate medical help for severe or worsening symptoms, breathing trouble, or a child who may have swallowed a large amount. Poison Control’s guidance describes serious poisoning as unexpected in typical exposures, while still advising prevention of chewing and sap contact.
What to do with a poinsettia after the holidays
Once the bracts fade, you have two reasonable choices: keep the plant as green foliage or attempt to produce another colored display. Keeping it as foliage requires ordinary houseplant care. Reblooming is possible, but it demands a healthy plant, enough bright daylight, and a long period of absolutely uninterrupted darkness each night.
Option 1: Keep it as a foliage plant
Continue the light, temperature, and watering routine described above. Remove declining leaves and any spent material, but do not discard a healthy plant simply because its bracts have lost color. Without the rebloom schedule, it may remain green rather than producing a new holiday display.

University of Minnesota Extension’s schedule begins with pruning a leggy plant in February, pruning and transplanting in spring, moving it outdoors in summer, and returning it indoors in September. Around the fall equinox, it calls for 16 uninterrupted hours of darkness followed by 8 hours of bright light every day. Keep night temperatures in the low 60s°F, continue the treatment until about Thanksgiving, then place the plant in a sunny location.

- LIVE PLANTS: Our plants are grown exclusively for Deep Roots and The Three Company, shipped fresh directly from our greenhouse to you!
Penn State uses a different calendar: begin around October 1, provide at least 14 uninterrupted hours of darkness each night, and continue until about Thanksgiving. It also cautions that a rebloomed plant may not be as full or vibrant as a newly purchased nursery plant.
| Rebloom element | University of Minnesota Extension | Penn State Extension |
|---|---|---|
| When to begin dark treatment | Around the fall equinox | Around October 1 |
| Uninterrupted darkness | 16 hours nightly | At least 14 hours nightly |
| Bright period | 8 hours daily | Not separately specified in the retrieved schedule |
| When to stop | Around Thanksgiving | About Thanksgiving |
| Expected appearance | Color after sustained treatment | May be less full and vibrant than a nursery plant |
These are source-specific schedules rather than a single universally standardized prescription. Choose one schedule and follow it consistently. A closet, cabinet, or opaque box can provide darkness, but the cover must not admit light from lamps, televisions, hallway fixtures, or sunrise. Even a small leak during the required dark period can interfere with the response. During the bright period, return the plant to its strongest available natural light.
Reblooming decision checklist
Attempt the project when all of the following are realistic:
- You can maintain a daily dark period for roughly two months without missed nights.
- You have a bright window for the plant’s daytime exposure.
- The plant is healthy enough to carry new growth through the schedule.
- You are comfortable with a result that may be smaller or less vivid than a commercial plant.
Buy a fresh poinsettia instead when you cannot guarantee darkness, your plant is already severely damaged, or the full nursery appearance matters more than the growing challenge. Neither choice is a failure: a green poinsettia can remain a useful houseplant, while reblooming is a time-intensive experiment in seasonal light control.

Soil stays wet and leaves decline
Remove foil or the outer pot, confirm that drainage holes are open, and empty standing water. Resume watering only when the surface is dry to a light touch or the pot feels light.
The plant wilts repeatedly
Check the soil before watering. If it is dry, water thoroughly through the drainage holes and let it drain. If the soil is already wet, adding more water can worsen root problems; improve drainage and inspect the container instead.

Color does not return the next year
Review the dark-treatment schedule for interruptions. The plant needs long, continuous nights, not merely a generally dim room. Confirm that lamps, room lighting, and daylight leaking around a cover are not breaking the dark period, and verify that the plant receives bright light during the designated day.

Sources and scope of the guidance
The care recommendations above are drawn from University of Minnesota Extension, Penn State Extension, and Poison Control. Temperature thresholds, watering practices, and rebloom timing can vary with cultivar, room conditions, and geography. No population-level poisoning rate is established by these materials; an individual exposure story should not be treated as a statistic. The safest interpretation is practical: poinsettias are not expected to cause fatal poisoning in typical ingestions, but irritation, gastrointestinal symptoms, rash, and choking remain preventable risks.
