Edible Uses

Leaves - raw or cooked[172, 183]. They are said to taste of oysters[5]. No-one has yet noticed a resemblance to oysters though not many of the tasters have ever eaten oysters! The flavour is fairly bland, the leaf is thick and has a very mucilaginous texture - it is probably this texture that reminds people of oysters[K]. Root[22, 46, 61, 105]. Eaten by the Inuit of Alaska[183, 257]. Flowers - raw[172].

Cultivation details

Thrives in nutritionally poor sandy or gravelly soils in a sunny position[200]. Requires a very well-drained soil[188]. Dislikes shade[233]. Plants are resentful of root disturbance and should be planted out into their permanent positions as soon as possible[200]. This species is not very easy to cultivate[1]. Plants are very susceptible to slug damage[188, K] The plant is heat tolerant in zones 7 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is a tap root similar to a carrot going directly down [1-2].

Plant Propagation

Seed - sow as soon as it is ripe in a cold frame. Spring sown seed is also successful[K]. Germination usually takes place within a month. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in April or early September. With care since the plant resents root disturbance.
