A Love for Annual Vines from SeedA Love for Annual Vines from Seed
By Joannabanana on May 26, 2013

There are many annual vines that are very easy to start from seed. Some of these vines are enormous and will give you a gorgeous vertical display in the right spot. Most annual vines can be started from seed early, indoors, and/or direct sowed after the danger of frost is past. Many are suitable for either container gardening or directly in the ground.

This plant reaches upward quickly and is a good subject for covering a naked support. I sometimes forget how much I like it. It never seems to get pollinated in my garden despite being a popular destination for hummingbirds and bees, and I was never able to collect seeds until a few years ago when I had success hand pollinating between flowers.

Fast growing flowering vine. Very interesting and showy flowers, the flower changing color from day 1 very pale to day 3 darker color. Easy to root from cuttings as well as easy to germinate from seeds. Very popular choice for high fence or arbour/pergola.
