    Light Needs:
    <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 plant is known as the Syrian mallow because it was introduced into Europe before the 16th century by Arab traders who originally collected it from Eastern Asia. It is well noted in ancient Chinese literature as well as that of Vietnam and Korea. It is included into the mallow family containing over 200 species from around the world. The purple coloring or blue has been contributed by early breeding with H. s. amplissimus, a common ancestor to all but the original white strains.
    The species name, syriacus indicates the belief that the Arabian plant originated in Syria, but is in fact an Asian plant.
