Let's start drawing with a big flower which to be the second from below. So, edges at petals of this plant not equal, wavy. Draw the biggest top petal, then two lower, lateral and stamens.

Now we draw a gladiolus flower the first from below. We draw by the same principle, as well as the first.

Draw flowers which are behind two main which we already drew.

We draw the most top flower, leaves, a stalk and kidneys.

It is possible to shade a little. The bouquet of gladioluses is ready.
