In a large bowl, dissolve yeast in warm water. Add the butter, parsley, rosemary, salt, sage, thyme and whole wheat flour. Beat until smooth. Stir in enough all-purpose flour to form a soft dough.
Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 30 minutes.
Punch dough down. Turn onto a lightly floured surface; divide into 24 pieces. Shape each into a ball. Place 2 in. apart on greased baking sheets. Cover and let rise in a warm place until doubled, about 30 minutes.
Brush with additional melted butter. Bake at 425° for 25-30 minutes or until golden brown. Remove from pans to wire racks. Serve warm.
