The Queen had red Camellias on her desk, when she addressed the nation.
A noble Death
Q asked about state funeral.
"The camellia is an early spring flower native to Asia. In Japanese, this flower is known as tsubaki. They were very popular with nobles during the Edo Period. Among warriors and samurai, the red camellia symbolized a noble death. Otherwise, the red camellia means love. However, they don’t make good presents for people who are sick or injured because of the way the flowers “behead” themselves when they die."
