They will grow in any soil, flowering uncomplainingly if they have sun. Since they flower only until frost, seeds can be planted indoors in fiber pots one month before the outdoor planting date to lengthen the flowering period. Soak the seeds overnight in water to soften the hard seed coat. Transplant, pot and all, when the weather warms. Provide trellis for support, they will quickly twine to 10' and cover the support with plentiful blooms.
Morning glories are poisonous.
