Cultivation:
Prefers a good deep loam and a position in semi-shade. Requires a sheltered position. Plants are hardier when grown on poorer soils. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[. This plant is very closely related to A. elata and is included in that species by many botanists.

Propagation:
Seed – best sown as soon as ripe in a cold frame. Stored seed requires 3 – 5 months of cold stratification. Germination usually takes place within 1 – 4 months at 20°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in a greenhouse for at least their first winter. Once the plants are 25cm or more tall, they can be planted out into their permanent positions, late spring or early summer being the best time to do this. Root cuttings 8cm long, December in a cold frame. Store the roots upside down in sand and pot up in March/April. High percentage. Division of suckers in late winter. Very easy, the suckers can be planted out direct into their permanent positions if required.

Edible Uses:
Young shoots – cooked. They can also be blanched and used in salads.

Medicinal Uses:

Do Some Fish Oil Supplements Contain Mercury?

Fish oil supplements are increasingly popular, but it has sometimes been suggested that they could also expose you to the harmful pollutants found in some species of fish.

However, studies have found that most of the widely available supplements contain little or no mercury, dioxins or PCBs.

Most companies use species of fish that are lower on the food chain, like cod and sardines, that accumulate less mercury. Many companies also distill their oils to help remove contaminants.

A report by ConsumerLab.com, which conducts independent tests of supplements, examined 41 common fish oil products and found none contaminated with mercury or PCBs. Another report, by researchers at Harvard Medical School and at Massachusetts General Hospital, studied five popular brands of fish oil and found that the brands had “negligible amounts of mercury.”
