I Supposedly Planted Dark Knight Bulbs, But They Are Still Green. Do The Leaves Turn Dark At Maturity/blooming Time?

Question

The plants are doing great, they are just not the dark brown color I was expecting

Answer 1

I'm not certain which bulb you mean, but maybe you are referring to Black Knight Canna. If this is the case, they will need full sun to obtain the dark coloration.
