Could be Dutch but is more likely Swedish or Danish. The bottle is made in the so-called half=post technique, whereby an initial glass blob was coated a second time so there would be sufficient material to blow into a large bottle. This technique was extensively used in Denmark and Sweden. A similar bottle is in the 1853 Holmegaard catalogue as "Cantineflaske" - it came in 4 sizes, with or without stopper.
The decoration is tulips, 100% tulips.
