way to go Jolana!....in time you will be able to see the difference between the new roots and the spikes...both are great as it means your plant is happy. The spikes are initiated by a cool spell..which for most of us,, means the fall. The spikes kind of look like pale green mittens..where the roots are perfectly smooth and pointed..sometimes they are green and white..I'll have to look through some of my photos to show the difference...but in the meantime enjoy your happy plant and welcome to our fun group here!
