Botanical Guardian Spell - Witch Soldiers

  In order to have access to a wide variety of botanical magic,
witches have historically maintained extensive gardens
full of unsual and beautiful plants.
(consider the witch in "Rapunzel.")
Traditionally, witches have also often been healers
and midwives, too, so that the witch's garden was
originally filled with therapeutic as well as purely
magical plants. By the Middle Ages and the advent
of the Burning Times, however, a witch's garden
was by necessity a protection garden, designed to keep
persecutors out and guard those within. The classic
European witch's garden was surrounded with three rows
of scarlet flowers, known as  "witch's soldiers" to
serve as the front line of protection against
witch hunters.
