Answer: Hypericum patulum Sungold would typically grow about two feet tall and three feet wide at maturity, but as with most plants it would need a few years to reach its maximum size and blooming potential. For best results, trim it back each spring to encourage vigorous new growth during the summer. Since it blooms on the new growth, do not prune it during the growing season. Finally, this plant will bloom best if the soil is not allowed to become overly dry and our drought season has been very difficult for many new plants, and particularly for new ones. Let's hope for better performance next year.
