Hi..I am a sweet pea nut!! I have to have them every year! We moved from Wa State to Denver Colorado one year ago. Sweet peas grow wonderfully in Wa but was told not so good in Denver. Well they are over three feet tall and blooming beautifully, I am so thrilled. They do need their roots cool and the tops in sun but not hot hot sun.I get my seeds from Thompson and Morgan and I love the quality. They do need alot more babying here I am learning. But they are worth it...because when I smell them they make me smile :)
