Some people are allergic to the milky sap and may develop a rash when exposed to the sap. Avoid breaking the leaves and stems which releases the sap.

Commercial growers work hard to produce high quality plants for the public.
If light is lacking, the leaves usually drop before the bracts. Adequate light results in longer leaf and bract retention. After the bracts have faded and the plant is no longer attractive, watering frequency can be reduced and the plant should be held in a cool location, such as 50-60 o F. However, if the foliage is still attractive, grow the plant on as a foliage plant. In March or April, cut back the original stems to within four to six inches of the soil surface. If the plant is too large for the pot, shift to a larger container using a good potting mixture from a local florist, greenhouse, nursery or garden center.
