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.
Plant year-old hollyhock plants from the nursery or garden center in early spring. Make sure the last cold frost, in your location, has passed. You can plant these perennials by seed, but they will not flower the first year. Dig a hole deep enough to accommodate the original pot size.
