“Rocky Mountain Raspberry is native to USA.
It can grow up to 10 feet in height. The fragrant flowers are around 2-3 inches in length with five bright white petals. The fruit is edible, dark red in colour and is said to be delicious.
Edwin James, a botanist, geologist and surgeon first collected it in 1820 for western science at Boulder Canyon in Colorado, USA. This also gave it the common name Boulder Raspberry.
This particular species of raspberry does not have any thorns unlike its counterparts.”
