The first example is a honeysuckle flower.

Stage One

At first capture the overall shape of the flower, plus I have included the stem to show where the petals grow from.

Stage Two

Next start adding the petals, measure one part against another to get the proportions right.

Stage Three

Now I have added the lower parts of the petals.

Stage Four

Here I have added the leaves on the stem and detail to the flowers.

Stage Five

I have now added the overall shape of the stamen to the flowers.

Stage Six

And here is the finished drawing. I have rubbed out any lines that I don't want, added the stamen and some shading.
