Give huckleberries a bit of room and they will spread to form a thicket just 3 feet tall. Many species of butterflies visit the bell-shaped flowers in springtime. The flowers are self-fruitful but tend to produce more fruit if two or more are planted together. The purple-black berries ripen in late summer and early fall to the delight of humans and a huge range of birds and other beneficial wildlife. The dense branching provides shelter and nesting to a wide variety of birds. Small, oval leaves turn beautiful shades of orange and crimson in the fall.
