Origin & Breeding History: The variety 'Overedclimb' originated from a controlled cross conducted by the breeder, Julie Overom, of Barnes, Wisconsin, USA. The cross was made in July 2006 in Wisconsin, USA between two unnamed parents. From the resulting progeny, the new variety was selected as a single plant based on its bushy, climbing plant growth habit, semi-glossy medium green foliage, many leaves, deep red coloured flowers and disease resistance.

Tests & Trials: The comparative trial for 'Overedclimb' was conducted outdoors during the summer of 2020 in St. Thomas, Ontario. The trial included 9 plants of the candidate variety and 10 plants of the reference variety. All plants were grown from bare-rooted cuttings and transplanted into 13.6 litre containers in June 2020. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety on July 23, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
