Garden notes
• The tall, green spikes add interest to a mixed annual border.
• Some sources say bells of Ireland is deer-resistant.
• Vase life for fresh flowers is 7 to 10 days.
• Flower spikes make interesting dried flowers. To dry them, pick a dry day when flowers are fully open, near their peak of maturity. Remove unnecessary foliage, and gather the stems into bunches. Wrap a rubber band or twine around the end of the stems and attach the bundle to a hook or hanger. Hang upside down in a dry, well-ventilated place for three to five weeks until they're entirely dry. As they dry, the flowers fade to cream or tan.
