Answer: Meconopsis betonicifolia grows in the cool moist sections of zones 6-8, particularly the Pacific Northwest. They do best in light shade and need an acid soil (pH5.5-6.5). Good drainage is vital. Plants grown from seeds should not be allowed to flower until their third year...so remove any buds. If plants are allowed to blossom when young, they die. The above information suggests that the seedlings be kept cool....maybe 55-65 degrees F. They normally bloom in early to mid-summer so light exposure can be kept on the longer length (12-16 hours).
