Hi I have a beautiful Ichroma, violet churur. I live in the Space Coast of Florida near Melbourne and Palm Bay and the plant has done fabulous since I bought it last February growing like crazy with the exception of the month of June it's been getting scraggly and I've noticed these little nodes. I don't know what to call them growing all over the branches. The growth coming out of the trunk is less and leaves are sparse but the growth coming out of the top just took off! Any idea what these nodes are?
