Scadoxus multiflorus, sub species Katherinae
We have a row of these growing like a small hedge, and each year they produce
a couple of dozen blooms and sometimes these berries form when the blooms have
finished. I actually grew mine from the berries originally and they took a
few years before we planted them in this row. I might add a photo later of
the hedge they have made. Eventually they die down for a few weeks, then
spring back into action with a new flower and greenery. All parts of the
plant are poisonous to eat, hence nothing really attacks the plants, except
the occasional snail.
