Survives zone 8 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

A minor, regionally endemic Azorean shrub with attractive urn-shaped flowers; the fruit is edible but mild — valued more for ornament than eating quality.

Wild

Years to fruit

2–3 yrs

Growth speed

Slow

Spacing

150 cm (59 in) apart — about 2.3 m² (24 sq ft) per plant

Leaf shape

Semi-deciduous, elongated lance-shaped leaves with sharp tips and serrated margins, bright green with new shoots emerging bright red.

Root system

Dislikes root disturbance — best grown in a container until moved to its permanent position.

Fruit description

Cylindrical black berries up to 2.5 cm long, fleshy and juicy though not very plump; mild but pleasant flavor.

Propagation

By seed (ripens Sept–Oct, sow with minimal covering) or semi-ripe/semi-hardwood cuttings.

Pollination

Largely self-sterile in practice — a reproductive-biology study of Azores populations found facultative xenogamy with only a minor role for spontaneous self-pollination. Needs a genetically distinct partner for reliable fruit set, more so than most Vaccinium.
