Question: Would moonlight nasturtiums be good for growing up an iron balcony railing that receives 8 hours of sun a day?
Answer: Yes, nasturtiums like full sun, as do morning glories and nearly all annual vines. (An exception would be sweet peas as they prefer cool spring weather and do not do well in hot summer weather.)
