Origin & Breeding History: 'Zolrolo' originated from a controlled pollination made in Enkhuizen, The Netherlands in 1999. The female parent, identified as T066 was crossed by the male parent, identified as T034. A single seedling was selected in April 2000 and propagated by cuttings. The new pelargonium was tested one year later at greenhouse and field performance trials in Enkhuizen, The Netherlands and evaluated for criteria including earliness, good branching, good and stable flower colour, flower size, rich and continuous flowering and resistance against Botrytis. In the same year it was tested in Sarrians, Southern France for heat resistance and resistance to drought stress.

Tests & Trials: Trials for 'Zolrolo' were conducted in a polyhouse during the summer of 2006 at St. Thomas, Ontario. The trial included 15 plants of the candidate and reference varieties. Rooted cuttings were planted into 10 cm pots on May 1, 2006 and then transplanted into 20 cm pots on June 26, 2006. Measured characteristics were based on 10 measurements. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
