If you are walking along the trail and you suddenly smell a most wonderful scent, chances are it is the Saffron Plum in bloom. The small, white, flowers grow in clusters from May to November. These flowers attract bees and butterflies. Edible berries ripen from green to blue-black, following the flowers. Many species of birds and mammals eat the berries. This plant has long, sharp spines at the ends of the twigs.
