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

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

Yellow Rattle is an annual
These lovely yellow wildflowers are annuals and therefore they rely on the production of enough seeds that will be dispersed ready for the next years flowers to appear.

Yellow rattles flowers are yellow and are a tube like shape which stick out from the green calyx. The flowers ( 13-15mm long) are 2 lipped and the upper lip often has 2 short violet teeth which you can just see in the top picture at the tips
