The truly dwarf nature of L. corymbosa makes it exclusively the preserve of pot cultivation as the small fleshy bulbs resent any kind of soil disturbance such as that caused by surface-foraging runner moles. As the bulbs have a shallow root system, they can be cultivated in a wide variety of shallow containers. Place the pots in a sunny position or one that receives high light intensity for at least half the day. In the Southern Hemisphere, plastic pots are preferred over terracotta ones as the latter tend to dry out too rapidly. The plants are seen to best advantage massed closely together, and planted in a free-draining mix such as equal parts of coarse river sand and finely sifted compost or finely milled bark.

Plant the bulbs in early autumn about 15 mm apart and about 10 mm deep. Water well and wait for the leaves to show, then water well once per week throughout the winter and early spring period, reducing water by the end of spring, and allowing the soil medium to dry out completely over summer. During the flowering period (late March to mid-May in the Southern Hemisphere), pots can be brought indoors where their brilliant flowers and strong sweet scent can be fully appreciated. L. corymbosa is not frost hardy and has to be grown in the cool greenhouse in cold climate countries of the Northern Hemisphere.

L. corymbosa is propagated by seeds sown in autumn, or by separation of offsets during the summer dormant period. Seeds can be sown directly into permanent containers, at a depth of about 2-3 mm, in the same medium recommended for adult bulbs. Be sure to sow the seeds thinly to prevent overcrowding, and keep the sowing medium moist by watering every few days with a fine spray. Germination of fresh seeds takes place within 3 weeks, and under ideal conditions flowers may be produced for the first time during the second season of growth.

The bulbs of L. corymbosa are long lasting and offsets form rapidly. When clumps become too thick and flowering performance diminishes, about every three to four years, the dormant bulbs can be lifted in summer and the offsets separated, and preferably replanted as soon as possible.

Like the other four species previously in the genus Polyxena, L. corymbosa is highly susceptible to infestation by mealy bugs that attack and multiply between the leaf bases and outer bulb tunics. Mealy bugs can transmit viral diseases from one plant to another, and are often spread by Argentine ants. Controlling ants goes a long way towards keeping L. corymbosa plants free from mealy bugs.
