You know they (Tiger Eyes) sucker wildly and can't really be herded any better than cats. They also don't live a long time, either. I have dug up and potted 3 or 4 each of the last couple years that were out of place. I lost the top 3/4 of the biggest this year and a main branch of another one last year. I put in 4 or 5 twelve years ago and just when they got to the right height they started to lose upper branches, here and there, like a Gordy Howe hockey smile...
