Very common around Karamea and up into the valleys but you won't find this one in the "official" information sources.
The hybrids generally have a white fruit, despite C. propinqua usually having blue fruit and C. robusta having orange/red fruit. The hybrid fruit is pleasant, sweetish with the typical Coprosma taste of slightly bitter tomato.
These hybrids are every shape and size between C. propinqua and C. robusta. The hybrids are fertile and back cross, leading to hybrid swarms where they are established.
Typical form at the estuary at Karamea
