black tree fern · Sphaeropteris medullaris
Also known as: black-stemmed tree fern; gray tree fern; mamaku; sago fern

In areas prone to frost, grow in a container under glass with a minimum winter temperature of 10°C. The plant may be placed outside during the summer in a sheltered and partially-shaded spot. It requires a moist but well-drained, humus-rich soil; in hot, dry summers water the stem as well as the soil, but avoid watering the crown in winter. Apply liquid fertiliser monthly during the growing season. Will grow without winter protection only in milder areas. See how to grow tender ferns outdoors for further advice
