I planted a package of Blue Star morning glories - next to my flagpole. Took a long time, but they finally started really growing - and growing - and growing. When we weren't looking, they encircled the flag and bound it to the pole! The pole is about 20' high, and the vine was reaching for the sky at last a foot above that. Took us a lot of work to chop it back and free that flag!. It's finally blooming - we left about 6 ft. at the bottom - and is beautiful. Next year I plant a short one.
