Welcome to meet another great stitch, the Zig-zag Petal Stitch. It is a nice combination of slanted Stem Stitch and Lazy Daisy Stitch. It is included in Edith John's Creative Stitches, but I came across it at Maggie's Textiles, and have with the aid of Rachel of Virtuosew Adventures confirmed the instructions.
Begin with a Lazy Daisy Stitch.

Anchor it and come up where you started.
Take a slanted Stem Stitch, pointing upwards
and coming out in the middle.
There, plant another Lazy Daisy Stitch, pointing in
the other direction.
Anchor it and come out at the starting point as before.
Make another Stem Stitch, this time
slanting downwards, come out where
you touch the first Stem Stitch.
Make the third Lazy Daisy Stitch,
and continue in the same way.
You can of course change the size or
the angle of the Lazy Daisy Stitch.
