BTW, leeneia, since you cited mulberry in your refrain, from the same Magickal Herbs list,
mulberry = protection, strength
---both very important if you're casting a spell, because the user of magick renders her/himself vulnerable by that very deed, on the old principle of "you live by the sword, you die by the sword." So you need what Dion Fortune described as "psychic protection."
I wonder too if the dove flying over the mulberry was a pacifying element in the spell? Some versions have the "dew" flying over the mulberry tree, whatever that may add...maybe it waters all those flowers.

PS I'm going to keep an eye out for other flower refrains and will post what I find.
