Entering the Newport Flower show Horticulture Division is easy and everyone is welcome! You do not have to be a member of a garden club or a horticultural organization. There are horticulture classes for all levels of gardener – from the weekend dabbler to the experienced horticulturist. So, bring your favorite plant, your prettiest cut specimen or plant something completely new, inspired by this year’s flower show theme.
Entry rules and guidelines will be available in early 2017.
How to properly measure a container
Size is measured as the longest inside dimension across the top of the pot; rectangular pots are measured on the diagonal. Disguised double potting is permitted. The inside pot is the one to be measured.

Flower Show “Lingo”
Passers check to make sure exhibits are of show quality, properly groomed, pest and disease free, are in appropriate containers, meet class specifications and are labeled correctly.
Cleaning flowers and plants to remove dirt and spray residue as well as dead foliage or flowers. Grooming should not alter the typical features of the plants or flowers.
Designing the Show layout of horticulture exhibits.
Identifying all flower and plant entries with correct botanical names. Include the common name, botanical name and species or variety.
Examples: Common Botantial Species/Variety
Lily Lilium ‘Casa Blanca’
Lavender Lavendula angustifolia ‘Hidcote’
Cut outside plants in early morning or late afternoon/evening – not in the middle of the day when it’s hot. Give specimen a fresh angle cut under water with a clean instrument, then place it in room temperature water in a cool, shady area for 2 to 12 hours. No leaves or flowers under the water. Optional: Use a plant preservative.
Plants exhibited primarily for their foliage. A few flowers on the plants are acceptable unless noted.
Annual Plant: A plant that usually germinates, flowers and dies in one year (cannot naturally winter over).
Perennial Plant (Herbaceous)
: A plant with non-woody stems that lives for more than 2 years, flowering over many seasons (hardy).
A plant that takes between 12 and 24 months to complete its life cycle. Can self-seed (i.e: Foxglove).
: A plant naturally occurring in an environment: essential to providing food and shelter for wildlife.
Deciduous Trees and Shrubs:
Shed the majority of their leaves at the same time annually (i.e: winter).
Modern Garden Roses:
The predominant roses of today in active development by hybridists. Class of roses not in existence before 1867.
Old Garden Roses:
The classes of roses that were established prior to 1867.
Species Roses (Wild Roses):
The classes of roses which include both the truly wild species and those garden forms associated with them.
A group of one or more genera that share a set of underlying features. Family names end in -aceae.
Genus (Genera) (pl): Group of one or more plants that share a wide range of characteristics.
Group of plants that are capable of producing offspring similar to themselves.
Group of plants selected or artificially raised, distinct variants of species.
Vigorous healthy growth, general appearance resulting from growing in the correct environment.
Form: The shape that is the true or characteristic form of a flower or plant.
The material of which the flower is made. It should be strong, firm, crisp and fresh. The stem supporting the blooms should be strong and in proportion to the flower. The leaves should be in good condition and in proportional size to the bloom and stem.
Beauty due to a balanced proportion of parts on a flower or plant.
Form, design originality, aesthetic appeal, proportion and relationship to the container are all factors.
: Plants should exhibit mature characteristics as can reasonably be expected of growing conditions (e.g. greenhouse, under lights, outside).
