Sondra,
@Sall20, I have never really seen any sort of pest bother either my Canna 'Sunset' or my two gingers, 'White Butterfly' and 'Shampoo'.
I have some really nice Shampoo gingers, 2-3' tall. They haven't yet started growing those "cones". My White Butterfly gingers are now 6-7' tall, and getting close to growing their wonderfully fragrant inflos. I find that the Canna and White Butterfly plants grow and bloom quicker with 6-8 hrs. of sun but the Shampoo plants seem to flourish with some shade in the middle of the day, when it is hottest. All these Canna and Ginger plants are already well-priced, but will be especially well-priced for the NGA subscribers.
