This California native blooms in late March through April,
producing small sweet black berries by late May and June.
This native vine grows best in moist soils near a water source. The
vines become a very dense ground cover when allowed to naturalize. The
valley oak riparian forests of old had an understory that had a high concentration

competed with the native people for this early bearing fruit.
The California Blackberry flowers in March and April, producing small
flavorful blackberries by late May and June. Don't eat the red ones - they
are tart and sour. The berries turn a deep dark purple, or black, when
ripe and ready to eat. The prickles are tiny compared to the non-native
Himalayan Blackberry, but you still need to be cautious when picking these
some berries for wildlife, okay?
