Question
Dear Greg, my crown thorns blooms in light-greens flowers instead of coral-red.
Is the soil missing some mineral elements? What should i do to balance it?

Thank you,
Irina

Answer
Dear Irina,

Actually, there are varieties of your plant with that color flower.
See: http://hort.ufl.edu/floriculture/gpn/Crown_of_Thorns.pdf

The original plant had red flowers, but since man got involved there are many different colors available. Hope this helps.

Sincerely,

Greg
