note : statements of characteristics herein represent exemplary observations of the cultivar herein and will vary depending on time of year , location , annual weather , etc . ‘ pacific starlet ’ was first identified in a field with other seedlings in may 2010 at watsonville , calif . usa . ‘ pacific starlet ’ was first propagated asexually by crown division in august 2010 in watsonville , calif . usa . the crown on the original plant was dug and parted into basal cane pieces ( approximately 15 cm long ) with root attached and replanted into a selection plot elsewhere on the farm , resulting in a 3 - fold increase . in september 2011 , two actively growing primocanes were dug ( with root attached ) and shipped to lafayette , oreg . usa , where vegetative material was explanted and established in vitro for micropropagation . this propagation method has allowed extensive testing of ‘ pacific starlet ’ and aided in determining that this cultivar is genetically stable . age of plants used for this discussion : crown age of about 3 . 5 years and a cane age of about 8 and 16 months for primocanes and floricanes , respectively . age of plants used for the photographs in the figures : crown age of about 3 . 5 years and a cane age of about 8 and 16 months for primocanes and floricanes , respectively . type of greenhouse covering or growing structure , or field : high tunnel over a field planting . color terminology refers to the colour chart of the royal horticultural society , fifth edition , london , united kingdom ( 2007 ) (“ r . h . s .”). observations for floricanes herein were made in june 2013 . observations for primocanes herein were made in august 2013 . form / shape .— vase . growth habit .— erect . height .— 1 . 9 m as measured from cane base to cane apex . spread .— 40 . 8 cm as measured from lateral leaf tip to lateral leaf tip . propagation method .— division . time to initiate and develop roots .— 24 days . root description .— generally of thick diameter with a smooth , glossy texture . few feeder roots present . ‘ pacific starlet ’ generally produces spawn ( shoots ) from roots with moderate vigor . diameter .— base : 1 . 1 cm | middle : 0 . 9 cm | tip : 0 . 3 cm . length .— 1 . 5 -
