Best grown in tubs or large pots using loam
based compost with extra organic matter added, feed with
a high potash liquid feed every 14 days. In cold areas they
do better in a conservatory or greenhouse. They can also be
grown outdoors in a reasonably sheltered area. Keep moist
but never let them get waterlogged.
Do not re-pot until they are pot bound. In winter cover the
crowns with straw or peat. In cold areas they should be put
under cover for the winter. Half hardy.
