Rubus illecebrosus is a red-fruited species of Rubus that originally came from Japan (where it is called バライチゴ, roseberry), but is also very popular in some European countries like Lithuania. Common names include balloon berry[1] and strawberry raspberry. It has become sparingly naturalized in scattered locations in Canada, the United States, and South America.[2]
Rubus illecebrosus is a thorny shrub up to 1500NaN0 tall. Leaves are pinnately compound. Flowers are produced either one at a time or in clumps of 2–3, each with 5 petals up to 18frac=32NaNfrac=32 long (longer than those of most related species). Fruits are also unusually large for the genus, each oblong, red, up to 2frac=4NaNfrac=4 long with 50–100 drupelets.
