flourishing, luxuriant, harmonize, graceful, noble, refined
藹 centers on abundant, graceful growth: flourishing vegetation, luxuriant beauty, and by extension a harmonious, noble, refined character that grows naturally from such fullness.
藹 combines the grass radical 艹 with 謁, which likely contributes the sound アイ. The grass radical suggests a connection to vegetation, fitting the flourishing, luxuriant meanings.
The grass radical 艹 on top of 謁 suggests lush plants growing over a respectful meeting: imagine a noble, graceful garden so flourishing it harmonizes with the refined conversation below.
For アイ, picture an eye (アイ) gazing over a luxuriant, flourishing field of grass: the eye sees the graceful, noble growth.
