Morning glories (Ipomoea) are annual vines that bloom profusely in shades of purple, white, pink, rose and blue, along with bi colors.
The flowers bloom from early summer to the first frost, but in some areas of the country they act more like perennials. Their big, fragrant, colorful flowers attract butterflies and hummingbirds and in a single season can reach fifteen feet long.
The seeds are poisonous and need to be soaked in water for 24 hours prior to planting. Start seeds three to four weeks before the last expected frost date. Be aware they resent transplanting so be very careful when moving them into their spots outside. Seeds will germinate in about a week. If they are started too soon, some varieties will need a support to climb on, or they will start twining around each other. If the seedlings get to this point, just insert twigs in their pots carefully, so as not to damage the roots, and transplant as soon as the weather warms up.
Morning glories prefer soil that is not too rich, otherwise there will be few flowers and lots of foliage. Morning glories aren't water lovers, either, and will do well with average moisture.
