  • Care
    Care Information
    Thrives in humus-rich, evenly moist soil, with morning sun and afternoon shade; will tolerate bog conditions. Prefers cool summer regions. Moisture is especially important in sunny locations. Prune after flowering to encourage vigorous new growth. Requires two growing seasons for abundant flowering. Divide every 2 to 3 years in fall.
    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
    History:
    Introduced by Jelitto Perennial Seeds in 2011. The seed originated from the nurseryman Coen Jansen of the Netherlands who had been working with the legendary 'Alabaster', which originally came from the Georg Arends Nursery in Wuppertal, Germany. This selection features large flowering, with bigger blooms over a long season, and more vigor than Trollius 'Alabaster'.
