Origin & Breeding History: 'Poena' originated from a pollination between the female parent F0132-1 and pollen from unidentified plants of Verbena x hybrida conducted in August 2003. The new variety was bred and developed by the breeder Har Stemkens in Enkhuizen, The Netherlands. 'Poena' was selected as a single seedling in May 2004 based on branching habit, flowering time, flower size, no seed set and heat tolerance. Asexual reproduction by cuttings was first conducted in August 2004 in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'Poena' were conducted in a polyhouse during the spring of 2009, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 11 cm pots on May 6, 2009. Observations and measurements were taken from 10 plants of each variety on June 2, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
