Step 1: Understand the term:
Morimono is a Japanese style of floral art.
The word means piled-up or heaped materials.
It belongs to the Ikebana family of arrangements.
Step 2: Main feature - mixed materials:
Morimono does not use flowers alone.
It combines flowers with fruits and vegetables in one arrangement.
The produce is a main part of the design, not just a filler.
Step 3: Main feature - container and shape:
The materials are heaped or grouped in a low container, tray or basket.
The shape is low and spread out, unlike tall line arrangements.
Colour, texture and shape of the fruits and flowers are balanced with care.
Step 4: How it differs from other forms:
Moribana and Nageire are built mainly with flowers and branches.
Western mass arrangements use flowers and foliage only.
Morimono stands apart because fruits and vegetables share the stage with flowers.
Final Answer:
Morimono is distinguished by its use of fruits and vegetables along with flowers, heaped in a low container or basket.
