Thank you for your question! Indigo plants require full sun to partial shade with medium to dry, non-acidic soil. We’re not sure how this would compare to southeast Texas though.

Question actually. Would the plant grow in southeast Texas? I know the myrtles plantation in the far path grew it for a commodity . It makes me think it would but I want to ask. Does it grow in full sun or partial shade. Thank you!
