    Design IdeasMat-like campanulas are versatile in gardens. Dense growth makes an excellent groundcover that is popular for flagstone steppers framed by its bright green and blue blooms. It's an old fashioned lawn edging and is excellent for filling out bare ground in the filtered shade of tree groves. Many old homes feature this plant in foundation plantings where it grows up to the trunks shrubs and presses against building wall foundations. They are a fine addition to Japanese gardens around rocks and boulders. Use them to disguise ugly pond edges or exposed concrete in rock waterfalls.
  • Care
    Care Information
    Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Control weeds until the plants have filled in. Feed with a general purpose fertilizer.
    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 grouped with a large number of perennials known as bellflowers which are the signature genera for the Campanulaceae. The genus was classified by Linnaeus and named from the Latin for bell to describe the flower shape. It contains about 300 species, mostly from temperate regions of eastern Europe. This species is native to the northern Balkans and was originally classified as C. muralis by Franz Elder von Portenschlag-Ledermayer, 1772-1822). It was later renamed for him by Max Roemer, and Joseph Schultes, both German botanists and contemporaries of Portenschlag. Hybrids such as 'Blue Waterfall' often contain breeding that traces back to C. Elantes, another eastern European bellflower species.
