The Thrall Bowl was presented in 1973, in memory of Helen G. Thrall, to stimulate knowledge and love of gardening among the members. The bowl will be awarded each year to the member receiving the highest number of points for the year’s horticultural competition. Any member who has won the Thrall Bowl three times, retires from competition (R), but may exhibit at any time.

Scale of points for awarding Bowl:

1st – 6,                2nd – 4,               3rd – 3,

Honorable Mention – 2.

Every entry receives 1 point


              Directions for Thrall Bowl competitions are as follows:

   Unless specified otherwise, all plant material including container-grown plants entered in any class must have been grown by the exhibitor for at least three (3) months. For fall and spring competitions, plants must have been grown outside.

   Exhibitors may submit only one entry in any class or subclass.

   Exhibitors may exhibit a total of SEVEN (7) entries in the competition.

   Unless specified otherwise, exhibitors provide three (3) look-alike blooms of the same variety for small flowers (less than 1 inch) and minor bulbs; one (1) bloom for large flowers and major bulbs.

   All specimens are to be clearly labeled and exhibited in a clear glass container in scale with the stems and provided by the exhibitor. Water must be clean.

   All leaves are to be removed from below the rim of the glass container.

   Wedging with plastic wrap is permitted.

   Unobtrusive staking is permitted.

   Fruits and vegetables are to be displayed on a paper plate to be provided by the Horticulture Committee.

   Collections should be specimens that are different and a variety of sizes, forms and color are encouraged. Collections will be judged, in part, on artistic merit.

   If several stems of one variety or genus are exhibited there should be uniformity of size, stem length, color, maturity and form.



Members should read the orange Horticultural Handbook for additional information on entering competitions or call members of the Horticulture Committee for further help. Plant material may be entered in The Thrall Bowl Competition for display only if the owner does not want his/her entry to be judged for points. Entry forms for Thrall Bowl Competitions will be included with the Green Sheet as an attachment before each competition. This enables members to prepare entry information ahead of time as well as facilitating the placement process on the day of the competition. 

Please see for a list of display tips.
