Scadoxus multiflorus ssp katharinae is an evergreen, summer growing
perennial that requires semi-shade and will flourish even in heavy
shade. It may be deciduous and go dormant in winter in colder
Scadoxus rootstocks are planted just below the ground and are best
left undisturbed in the same position for many years. The soil must
be well-drained, rich and light, with plenty of leaf-mould or
well-rotted compost. Scadoxus multiflorus ssp katharinae likes
plentiful water when in active growth, but dislikes water-logged
This is a very useful plant for shady gardens.It looks particularly
effective in large groups under trees, where they do not seem to
mind competition from tree roots, provided the soil is good.
Propagation is by seed and offsets. The seed should be sown as soon
as it is ripe. This does not necessarily mean that the berries must
be removed the minute they turn red. If they are not under threat
from birds, or curious children, they can be left on without harming
the seed until they start to look a bit wrinkled, which should be
around early spring. Clean the pulp off, with care as the seed
underneath is soft and fleshy. The best is to rub or peel it off.
Use a well-drained, light potting mix, press the seed gently into
the soil, do not cover it but leave the tops just visible or level
with the soil surface. Keep damp but not waterlogged. Flowers can be
expected from the third season onwards. Offsets should be removed
after flowering i.e. in autumn, and replanted immediately.
