1 More than 3 million people died of COPD in 2012, which is equal to 6% of all deaths globally that year. 2  More than 90% of COPD deaths occur in low- and middle-income countries.  The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).
Hollyhock, Alcea rosea, is a summer blooming biennial that has an upright habit with thick sturdy stems. They are winter hardy to zone 3. Zones 3 to 8 begin blooming mid to late summer. In zones 9 to 10, young plants are set out in fall and bloom early spring through summer. Hollyhocks are drought-resistant.
Step 1. Buy your hollyhock seeds, or harvest them from the dried seed pods of spent blooms on established plants. If you look around, you may notice hollyhocks in the garden of your neighbor, friends or family. Ask if you can harvest the seed pods in late summer or early fall.
