In accordance with Ontario Judging and Exhibiting Standards, Publication 34


  • Stem or stalk: A main plant structure which supports flowers, buds, leaves, or fruit.
  • Scape: A leafless flower stem arising from the ground. Each scape carries a number of flower buds depending on the cultivar, e.g., Hemerocallis, Narcissus
  • Spray: A spray is the terminal flowering growth of an herbaceous or woody plant carried on one stem. Ideally it would show all forms, e.g. flowers in bloom, buds showing colours, green buds and leaves.
  • Spike: An upright stem carrying several flowers which are nearly stemless, e.g. Gladiolus.
  • Narcissus:
    “trumpet” – the cup or corona as long or longer than the perianth segments (surrounding petals), e.g. Mount Hood, Spellbinder.
    “large cupped” – the cup or corona is more than1/3 but less than equal to the length of the perianth segments, e.g., Ice Follies, Carlton.
    “small cupped” – the cup or corona is not more than 1/3 the size of the perianth, Birma, Barrett Browning.


  • Foliage Design: Design with interest in foliage. Foliage is to predominate. Flowers and/or fruits may be present but must be inconspicuous.
  • Mass Design: A design with a large quantity of plant material arranged in a closed silhouette with few or no voids.
  • Pave Design: In jewellery making a term that refers to setting stones so close together that no metal shows. In flower design pave is a echnique of placing groups of plant material that have been cut very short, close together to form undulating mounds of colours, textures, shapes and sizes. Any plant material, e.g., flowers, foliage, cut stems, fruits, vegetables, moss can be used.
  • Visible Use of Water Design: A Contemporary design type with the floral arrangement surrounded by water and 50% of the water is visible. Water line can be visible and is an integral part of the design.

For more definitions and information, please refer to the Ontario Judging & Exhibiting Standards – Pub. 34 (OJES).

The exhibitor wants to show the highest quality of plant material possible, from the time of selecting specimens to placing them in the proper classes. List or mark in the schedule the plants you are growing that will be at the proper stage for showing. Cut flowers and foliage the night before the show or early in the morning. Bring extra ones for back-up in a separate container.

Prepare plant materials for hardening

  • Remove lower foliage cleanly. Upper foliage must be attached unless otherwise stated.
  • Specimen blooms should not have side buds. In fact, good exhibitors will often disbud weeks before the Show.
  • Make a fresh cut, with the end of stems under water, for maximum water intake.
  • Place in a wide bucket in warm water for at least three hours, preferably overnight.
  • Store in a cool, dark humid, draft-free place.
  • Re-cut stems before placing in show containers.

Conditioning: Some cut flowers, foliage and woody materials do not readily absorb water and require further treatment prior to hardening, to prevent wilting during the show.

  • Ornamental branches generally benefit from splitting the cut ends. Some also may require removal of the thick outer layer.
  • Some cut flowers which exude a white latex or sap benefit from burning the stem ends, e.g., Poppies, Euphorbia.
  • Other cut flowers, benefit from placing stem ends in 2" (5cm) of boiling water for a minute or two before placing in cold water, e.g., Dahlias, Roses and Rudbeckia. Protect bloom with a paper collar.
  • Some spring bulbs prefer being placed in 2" (5cm) of cold water.
  • To prolong the life of a tulip, the small air sac at the very top of the stem where the bloom joins the stem should be pierced with a pin to allow water to flow up to the bloom.

Grooming is essential. Remove evidence of insects, disease, dust, stains, pollen, and any other foreign material from blooms and foliage.


  • A bud showing colour is considered a bloom.
  • Only attached foliage is permitted unless otherwise stated in the schedule.
  • Wiring, oiling, spraying and artificial colour are prohibited in the Horticultural Division.
  • Check schedule for required number of specimens in the exhibit.
