Traditional Line Mass

Below are scanned pictures of Line Mass Designs that have been published in “Creative Flower Arranging” by
Betty Belcher, published in 1993.  It was required reading for Federated’s Flower Show School.

The Line Mass Design was a new style developed in
America during the early 1930’s.  They are based on:
1.  geometric forms
2.  one focal area at or near the point of emergence
3.  even numbers of any one plant material is considered improper.

Below is additional  information about traditional line mass designs from the article “What is Traditional?” by Kathy Noble in the Rose Arranger’s Bulletin Late Summer/Fall 2010
Traditional Line Mass


1.  Merge best qualities of Oriental Line & Occidental Mass.
2.  Have an open silhouette.
3.  Additional plant material used is massed to enhance
and strengthen the line.
4.  The dominant line is fortified with a mass of plant material
at the focal area.
5.  A Line-mass design is closer to a Mass design than a
Line design… though the linear quality predominates.
6.  The strongest part of the design is through the center,
balance and symmetry originate from the central axis;
7.  Materials with the most prominent characteristics (the
roses) are placed there to draw attention to the area.
8.  Line-mass designs follow vertical, horizontal, crescent, triangle
directions of Line designs (e.g. 90˚ angle shown above).

Traditional Line-Mass  arrangements are “open”forms in which the plant material does not completely fill the geometric form on which the arrangement is based.

Hogarth Curve Traditional Line Mass

For those of you who are unfamiliar with a Hogarth curve- Don’t Panic!

This is an illustration of a Hogarth curve for the purpose of rose arrangements.

The dotted lines depict the two ovals upon which the Hogarth curve is based.

The top oval is larger than the lower one;

this is usually a 5:3 ratio in height.
