Thimbleberry
(Rubus parviflorus)

The Thimbleberry plant produces edible fruit approximately a centimeter in diameter. When the fruit ripen in mid to late summer it is bright red. Like other raspberries it is not a true berry, but instead an aggregate fruit of numerous drupelets around a central core.

The drupelets may be carefully removed separately from the core when picked, leaving a hollow fruit which bears a resemblance to a thimble, perhaps giving the plant its name
