I am curious to know how typical it is for seedlings in monocot groups to have no chlorophyll.
This fall I noticed a tall Agapanthus in my garden had a few seeds on the stalk, so I gathered
those that were left and sprouted them on a window sill, along with seeds from a Watsonia. So
far, 14 of the 16 Agapanthus have chlorophyll, 2 do not, 12.5 percent. The Watsonia pot has 12
seedlings, 11 have chlorophyll, 8.3 percent.
12.5 percent seems high for a known fatal condition among photosynthetic species.
How common is this condition?
I suspect more common among monocots than any of us realize. I've grown bamboo from seed (on those rare occasions when any is set), and iirc a good 50% of the seedlings lack chlorophyll.
