Mr. W. Scott, of Bury Hill, gives these particulars as to its culture: -

"It naturally requires about six months' rest, and will seldom start for growth before March, when it will require a good bottom heat of at least 80°, either in a bark-pit or cucumber-bed. The greatest error committed with regard to its treatment is leaving the root to start in the same pot, etc, it grew in in the previous year. As it makes its shoot from the lower end of the new tuber, which is consequently at the bottom of the pot, if it is not taken out, and that end placed upwards, it has to struggle through the whole mass of mould to reach the surface, which it often fails in doing. It should be potted at the beginning of March in a forty-eight pot; or, if the tuber (which sometimes happens) is too long, a bulb-pot may be used. It should be well drained, and planted in pure light peat or heath mould, with the end of the root just above the surface. When it makes a shoot, it also forms fresh roots from the base of the new shoot, and will grow rapidly if kept in a stove or vinery at a temperature of 70° or 80°, and soon requires a larger pot.

It generally takes a six, using nothing but light peat soil.

"It may then be trained in any form most convenient. After it has flowered and the leaves are decayed withhold water entirely to ripen the tubers, which may be kept in the dry mould till the spring, or taken out and kept in dry sand till the season for potting them." - Gard. Chron.
