This is one of those plants like a Poinsettia.
The red things are actually technically more like
leaves than actual flowers, they are called "Bracts." The real
flower is a small white bloom that comes out from
the center of the groups of red leaves. You can see
a couple of the buds in this photo.
Although they are not technically part of the flower
the bracts serve an important role in the pollination
of the plant. They act as kind of a beacon
for pollinators that might otherwise miss the small
white flowers as they fly by.
Daisies are another type of plant
with a similar structure. What is commonly called a
daisy flower is actually a cluster of small flowers
(called the Capitulum) surrounded by bracts.
In this image the
bracts are white and the capitulum is yellow.
