How to let purple Calla Lily flower grows again with color ?
I just received a calla for my anniversary. The green growth is probably new flowers. Actually , callas are outside plants. If you are lucky and depending on where you live, if you plant it outside, it may come back next year. I have never grown one inside. They grow from corms, which is similiar to a bulb. I worked in a flower shop for years.Good luck. oh, as long as it is blooming, I would cut the blooms and put them in a vase. Very little water or they will drown due to hollow stems. 2inches per 5 blooms. This also sigmals the plant to keep in blooming for awhile. The flowers can last up to two weeks in water!
Reply:More artificial light and longer hour can%26#039;t help you.
Reply:You can%26#039;t. The bulb is done. Retire it, and wait for the next blossoming cycle.
