Ikebana flower arrangements are mostly known for their minimalist aesthetics. Unlike the typical Western styles, which predominantly focus on creating large volumes of blooms, Ikebana puts equal emphases on the three main elements: mass, color and line.
This image is a simplified representation of an arrangement with the 3 elements being added one by one. First mass, then color and at the end the horizontal lines join the composition. See how they work together and change the overall impression of a simple Syringa (Lilac) branch?
Out of the 3 elements we are most familiar with the mass. Traditional bouquets are essentially masses of flowers. Color is an obvious one as well. But the line is not used much in the Western floral art. On a rare occasion we might see a line of a brunch being emphasized but that is pretty much it. Such details as flower stems or roots are almost never in the spotlight. Bamboo stems, reed, tall grasses can also provide wonderful inspiration and give a sense of movement to a composition.
But Ikebana flower arrangements do not have to contain all three element all the time. Sometimes you might consider focusing on one element and showcasing its beauty. It is all about balancing the 3 and using them effectively to create arrangements, which express your ideas and feeling.
To explore this topic further read the following articles focusing on mass, color and line. In those articles we provide illustrations of using each element in different types of arrangement. There is also some theoretical insights such as link to the color theory.
