Bramble Scramble

I scrambled on the hill, avoiding any spill. The rocks required some skill to stay upright. A covering of leaves, hid brambles, thick as thieves, and roots, I do believe, lurked out of sight. So pick your path with care, some sturdy shoes to wear, with lots of sunshine there, not at first light. ---------- A Violette, which seems to me a tail-rhyme with specific additional requirements: 6/6/6/4 stanzas with aaab, cccb, dddb rhyme. (You can continue with more stanzas, all using the 'b' tail). There is a mention of a 'feminine rhyme', but I've not found a good definition for that yet.
