Royal Helen is the second of the new "darling" sisters known for producing premium-quality fruit. Royal Edie and Royal Helen can be planted together as pollenizers and packed in the same box. Both varieties mature three to five days after Bing, but offer better size and crack-resistance. The upright tree produces some doubles and spurs, similar to Bing, but has remarkably larger, more beautiful fruit. Growers have reported that 90 percent of the packout sized at 9.5 row or better. This cherry does well in both high and low chill environments. (U.S. Plant Patent No. 19595)
