Yellow Rattle - Hebrides Wildflowers
These lovely tubelike yellow flowers display through the summer months on the machairs, meadows and roadsides. The stems can reach 2ft in height and the yellow 2 lipped flowers often have a violet tooth at the tip.

Name From the Rattling of Seeds

The name of this plant is though to have been given originally as during the summer months when a breeze occurs, you can actually hear the seeds rattling in the calyxes or brown seed capsules which occur once the flowers are finished.

This was said to indicate that the meadow was ready to be cut for hay

Stems up to 2 feet in height
The stems can grow in height up to 24 inches and have black spots on them.

We are lucky here in the Hebrides to see this flower thriving so well on the meadow like land as many persons throughout the Uk, now buy the wildflower seeds which are included in many mixed wild seed packets.

These lovely yellow wildflowers show their faces from May through to September

Pollination
The flowers are typically pollinated by bumblebees, but if they are not pollinated they can self-fertilise
