Rikka
The oldest formal style of ikebana: a tall, upright arrangement that pictures a whole landscape.
Also: tatebana
Rikka means standing flowers. It developed in Japan from Buddhist altar flowers and was given its form by the priests of the Ikenobo school in Kyoto. A rikka arrangement is large and upright, set in a tall vase, with several main branches in fixed positions that together suggest mountains, waterfalls and valleys. It was made for temples and for the great houses of the ruling class. The simpler styles that followed were partly a reaction to its scale.
