Edible Uses
Edible Parts: Leaves;  Root;  Stem.
Edible Uses: Sweetener.

Root - baked[105, 153, 173, 177]. It can also be brewed into an intoxicating drink[183]. Pith of the trunk - dried and steamed until soft[173]. Sweet and starchy, it is used to make porridge or a sweet drink[173]. The root and stems are rich in fructose, the yields compare favourably with sugar beet (Beta vulgaris altissima)[153]. Edible shoots - a cabbage substitute[105, 128, 173]. The leaves are very fibrous even when young, we would not fancy eating them[K].
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.



None known
Other Uses
Fibre;  Paper.

The leaves contain saponins, but not in commercial quantities[153]. The leaves contain a strong fibre, used for making paper, twine, cloth, baskets, thatching, rain capes etc[1, 46, 61, 128, 153]. The whole leaves would be used for some of these applications. When used for making paper, the leaves are harvested in summer, they are scraped to remove the outer skin and are then soaked in water for 24 hours prior to cooking[189].
Cultivation details
Industrial Crop: Fiber;  Management: Standard;  Minor Global Crop.

Prefers a good sandy loam rich in humus[1]. Succeeds in full sun or light shade[188]. A very wind hardy plant, tolerating maritime exposure[49, 166]. A very ornamental plant[1], it is not very cold-hardy, tolerating short-lived lows down to about -10°c[260]. It only succeeds outdoors in the milder areas of Britain[1, 11, 59]. It grows very well in Cornwall where it often self-sows[1, 11, 59]. A form with purplish leaves is hardier than the type and succeeds outdoors in Gloucestershire[11]. The flowers have a delicious sweet scent that pervades the air to a considerable distance[245]. Mice often kill young plants by eating out the pith of the stem[11].
Propagation
Seed - pre-soak for about 10 minutes in warm water and sow in late winter to early spring in a warm greenhouse[78, 164]. The seed usually germinates in 1 - 3 months at 25°c[164]. There is usually a good percentage germination[78]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in late spring after the last expected frosts and give the plants some protection in their first winter outdoors[K]. Stem cuttings - cut off the main stem just below the head and then saw off 5cm thick blocks of stem and place them 3cm deep in pure peat in a heated frame. Keep them moist until they are rooting well, then pot them up into individual pots. Plant out in late spring after the last expected frosts. Suckers. These are best removed in early spring and planted out in situ. Protect the division from wind and cold weather and do not allow the soil to become dry until the plant is established. Divisions can also be potted up and grown on until established, planting them out in the summer.

I have had some success growing these plants from seeds, but have lost quite a lot with some form of root rot. The plants rots at the base and dies. Can you also explain in more detail how I can propogate from stem cuttings. Exactly which leaves do I take off, please

My sister has 4 cordylines..2 x green leaf and 2 x purpleish leaf. We would like to know if she re-pots them, would it harm the young plants if she puts them in very large pots to avoid re-potting again at a later date. We are finding that their roots very quickly outgrow a pot.

are the flower heads meant to be removed after flowering or will this damage the plant?
