    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    This improved selection from the National Arboretum is a sterile triploid, producing little to no seed, resulting in an extended bloom season. In 1971, a number of crosses were made between diploid Hibiscus seedling selections of (H. syriacus 'Suminokura-yae' x H. syriacus 'William R. Smith'),(H. syriacus 'Blue Bird' x H. syriacus 'Hanagasa'), or (H. syriacus 'Sokobeniyae' x H. syriacus 'William R. Smith') and colchicine-induced tetraploid seedlings ofH. syriacus 'William R. Smith'. The resulting triploids, 'Helene', 'Minerva', and 'Aphrodite' were released in 1980, 1986 and 1988, respectively.
