Edible uses

This section contains historical Plants For A Future notes marked noncommercial.

The tender leaves and shoot-tips are boiled as an aromatic tea[3][4]. A delicious drink[6]. Some caution is advised since boiling the plant or infusing it in hot water is said to release a toxic chemical[6]. It is safer to soak the leaves in a jar of water in direct sunlight to make 'sun tea'[6].

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - sow February/March in an acid compost in the greenhouse. Surface sow or only just cover the seed and place in a lightly shaded position[10][2]. The seed usually germinates in 1 - 2 months at 12°c[2]. Prick out the young seedlings into individual pots as soon as possible, they are prone to damp-off and so should be kept well ventilated[10]. Grow them on in the greenhouse for at least their first winter and plant them out in early summer once they are 15cm or more tall. Cuttings of half-ripe wood, 5 - 7cm with a heel, July/August in a frame in a shady position. Takes 15 months[10]. Layering in August in a semi-shady position. Takes 18 months[10]. Division in early spring. The plants should be 'dropped' beforehand[10]. This entails digging up the plant 6 to 12 months earlier and replanting it somewhat more deeply. The buried branches will then root and form new plants when divided.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Requires a well-drained, moisture-retentive, lime-free, humus- rich soil and a shady position[2][5][7]. Plants spread slowly by means of suckers when they are grown in a suitable position[5]. This plant is considered to be no more than a sub-species of A. polifolia, but with a more southerly range[8], by some botanists[1].
