i would find a local grower ... or orchard that grows them...and ask them what cultivar they grow... LOCALLY ...

my local orchard even sells plants in spring ...

though i love wallyworld ... i would not rely on plants shipped.. in bulk from arkansas ...

e.g.: googling : raspberry growers CA ... i found the link below ...

getting good cultivars.. really matters for berry production ... pay the money.. to get a good start ...

and do not expect much production the first season... and learn all about their biennial tenancies ... and how to prune them ...

and do look for EVERBEARING types... they give fruit twice a season ...

both of these berries.. are bramble... and can run from horrible ... huge ..... invasive-type plants... that barely berry ....

to good acting [blanking on the word i want] .... plants.. that nearly crush themselves with berry production...

its really worth it.. to get the right one...

ps: never met a blackberry that out performed a raspberry ....

pps: i have a yellow rasp.. fall gold.. to die for ... and heritage .. same ... i killed off dads historical plants.. years ago.... once i got these .. they grow well in MI ... no clue where you are ...

Here is a link that might be useful: link

they are not shrubs ... they have canes ... so you have severely limited your audience in this forum .....

but you might find more opinion.. in the fruit forum .... never know where you will find the expert .. sometimes they are hard to find.. like waldo ... lol
