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.
Spring - start seeding and planting hollyhocks. For early flowers start annual hollyhocks indoors 8 weeks before the last frost. Sow seed in peat pots and keep at 15C. Don't exclude light- this aids seed germination. Transplant hollyhock seedlings or container grown plants to the garden flower border after the last frost.
