Swing Low Distylium matures just 2-3’ x 4-6’ wide. However, it can be kept pruned to a smaller size so it doesn’t overgrow its boundaries. Do you like yellow flowers? If so, go with Cobalt-N-Gold Hypericum. We have several smaller maturing barberries including Daybreak, Pink Sparkler Birchleaf Spirea and Superstar Spirea have reblooming pink flowers.
