You are buying 5 Rooted cuttings / root stock shipped bare root. Each will be at least 2 feet long (often they are longer). You will get a combination of root stock (roots with no vines growing on them yet) and rooted cuttings (vines with roots). Most (or all) of the leaves will be removed from the vine for shipping.
This is the fast growing perennial BLUE DAWN FLOWER MORNING GLORY ( Ipomoea acuminata, Ipomoea indica ) (this vine does NOT GET SEEDS).
Each vine will easily reach 25-30 feet when established. This vine is a hardy perennial to USDA Zone 9a (for certain, because that is where I live), but I have had people tell me they grow these in the Carolina's and near Dallas, TX. If you are growing them north of zone 9, I would suggest overwintering indoors, however. They will also grow well in large pots for northern states so you can bring them indoors/into a greenhouse, and protect them in the winter.
These beautiful vines have an abundance of electric blue flowers that fade as the day goes on to a pink-purple. They don't really close up like annual morning glories, but stay open most of the day. These vines do not get seeds, but do spread with runners along the ground. These can grow in partial shade or full sun in average, well draining soil.
Easy maintenance plant - will grow anywhere! Do you have an embankment that needs a lift, or an arbor or archway . . . a dead tree, even that old fence (or new fence!) - you name it, these beautiful vines will add color and interest anywhere you plant them!
Since these spread with runners along the ground, make sure to leave enough room on the ground around the vine for the runners it will send out so they don't choke out other plants.
