It's hard to believe that a shrub as large as Starry Starry Night hibiscus will virtually disappear as the temps drop in the fall, but this beauty is indeed a perennial that goes dormant from fall until spring. We've seen stunning specimens that are four feet tall and wide at the peak of summer, with ultra-dark leaves serving as a foil for the flamboyant pink summer blooms. Pale pink petals are lined with deep pink veins radiating out from an even deeper pink center. This is a must-have for those looking to create a tropical-themed garden, or just want an awe-inspiring shrub.
