I have one of these and it opens its flowers in the morning but they close up quickly. I noticed they are opened in the shade but close after the sun is on them. They are potted, not yet planted out. Tag says full sun, but this indicates to me they don't like sun? or do they just open in the mornings? I just don't know anything about them. Are they really hardy? Just wonder if they need a lot of pampering, special soil or lots of water? Zone 5/6 ok for them over wintering?
TIA
