This tutorial on drawing a sunflower step-by-step might be one of the easiest ones. The pattern of a sunflower is similar to that of a Chamomile, except a sunflower is bigger in size and its petals are yellow.
Draw two circles for the floret and petals so that they have the proper pattern, followed by the stem and leaves beneath it.
It is best to draw and color the petals in the end of the drawing process.
It is too simple to draw a circle for the sunflower floret and a line for its stem by the graphite pencil. Draw a smaller circle inside the bigger one.
Trace lines onto the stem in free strokes to mark the sunflower leaves.
It helps to draw two circles for the floret in order to make petals look symmetric and uniform. The tips of the petals will lie exactly inside the circle for the floret. The sunflower floret has a small mount in the center of it, which you should also draw.
This way, the sunflower petals will be symmetrical and neat between two circles. You cannot get it wrong with a structure like this. The petals should look almost identical when placed strictly within the circle.
Now you can erase outer pencil lines of the sunflower petals.
Do so carefully so as not to erase the petals themselves.
It's time to erase the contours of the inside marks for petals.
Here, the sunflower pattern is almost completed. You need to color it in yellow but do so at the very end.
Now move on to drawing the stem and leafage of the sunflower. This should be relatively easy to do.
You are free to draw the Leaves, as you'd like; the floret itself is the major element to pay attention to.
Sunflowers usually grow in large numbers in sunflower fields, so it is good to draw some more sunflowers near the main one, even if they are smaller in size. This way, the picture will look more natural.
Your sunflower drawing will look amazing if you color the stem and leaves green.
I guess now you know how to draw a sunflower.
