Sorry, but this is not 'Cambridge Blue'. It is not the lovely palest blue that 'Cambridge Blue' is. It is a nondescript medium blue. Nothing special. Very disappointing.

Thank you so much for taking the time to share your thoughts. A flower might not bloom in the color you were expecting for several natural reasons, and it doesn’t necessarily mean something is wrong.
Soil conditions can play a role; certain flowers, like hydrangeas, change color based on soil pH and mineral content. Weather and temperature fluctuations, such as heatwaves or cold snaps, can impact pigment development and lead to muted or altered flower colors.Your feedback is invaluable to us, and we are committed to ensuring your experience is positive.

The seed quality is fabulous! I had 100% germination with little to no effort. My only complaint is that the seed packs aren't self sealing like most other seed companies.
