Canna Red (Canna x Generalis) - Growing Cannas from Canna seeds is extremely rewarding and brings a striking perennial to the landscape that gives a full season of color. This Canna Lily can grow 24 - 30 inches tall and gives a wonderful display with its colorful foliage and blooms of intense red color. Canna seed is one of the largest flower seeds you will find at only 5 seeds per gram. Due to this factor, it is best to soak the flower seeds for 24 - 48 hours before planting to soften the seed coat. For even faster germination, file or nick the Canna Lily seeds before planting. Canna seeds should germinate in 10 - 20 days at 76 - 80F.
Cut old spent flowers and seed pods to encourage repeated flowering late into the autumn season. Canna plants should be spaced 9 - 18 inches apart depending on the size of the varieties used and the effect desired. In dry weather, watering Canna Lily plants once a week will insure a stronger growth. Another common name for Canna is Indian Shot or Canna Lily. Canna grows best in wet locations. Nice for a water's edge, plantings near ponds and pools work well. Not hardy north of zone 7, but makes an excellent annual flowering plant. This Canna variety will often bloom in just 90 days after planting flower seeds.
