Evaluation
Cherry selection with a very late ripening time, in average 3 weeks later than 'Regina'. The highlight is the large proportion of good quality fruits, the excellent firmness and flavour.
When selecting the site, cold or frosty locations and areas with high precipitation, where the parent variety SWEETHEART ™ Sumtare (S) also shows difficulties with tree health, should be excluded.
If you are interested to plant KIR™-varieties outside of the Netherlands, Switzerland, Austria and Germany we need the authorisation of the licence holder LFP GmbH.
