All of the assets of the species Campanula poscharskyana, plus larger, deeper lavender-blue flowers with a white eye. They resonate against the rich green foliage from June to frost. We propagate this variety vegetatively to ensure that the plants are uniformly stunning.
Campanula is a fine group of garden plants in blue or white shades ranging from very dwarf to 6ft tall that look superb in the perennial border. Some bloom for the better part of summer. They need only a moderately rich, well-drained soil and full sun or partial shade. Campanulas are not well suited to the desert Southwest.

HOW PLANTS ARE SHIPPED
The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.
WHEN WE SHIP
We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.
We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

I love this variety! The blue flowers cascade over this slowy rambling perennial. It creeps in and around other perennials, filling in the holes and its blue color combines very well with light pinks and yellows. It establishes easily and of course, gets better with age.

Pretty leaves with colorful flowers. I ordered a single plant to try it out. Based on others' comments, this plant did not fill out in two years as I expected. It was hardy and survived the rains of Sandy during the fall I planted it and strong sun in the spring/summer.I would recommend that people buying this, should purchase multiple plants to fill in areas as described by other customers remarks.
Variable late spring through summer blooms in shades of blue, lavender, and violet predominate, but white and pink varieties are also available in this charming genus. Growing to heights ranging from 3″ to 30″, there is a Campanula for almost every garden situation, from the front of the rock garden to the back of the perennial border.
Light/Watering: Most varieties will do well in full sun or light shade, the latter vital in the South for all but C. persicifolia and C. pyramidalis. Campanulas prefer evenly moist soils with good drainage and are at their best in climates with cool nights.
Fertilizer/Soil and pH: Bellflowers thrive in average, well-drained soils with a pH range of 6 to 8 and will benefit from one light application of a balanced 10-10-10 fertilizer in early spring. A mulch applied in summer will help keep your plants' roots cool, which they prefer. Keep mulch 1–2″ away from the crown of your plants to avoid rot.
Pests/Diseases: Campanulas are generally pest-free but watch for distorted growth or yellowing leaves that may signal an aphid infestation. If aphids are apparent, spray them with insecticidal soap. Slime trails and ragged holes in the foliage indicate slug predation. Intervene before populations build by handpicking, trapping, or using physical barriers like diatomaceous earth or copper sheeting.
When cultural conditions are correct, Bellflowers rarely become diseased; however, they may contract rust diseases or rot diseases. Rust looks like powdery, reddish brown or orange pustules on the undersides of leaves. Remove infected foliage and plant parts and treat plants with wettable sulfur at the beginning of the next growing season to prevent recurrence. If plants turn black at the base and the crowns seem to be rotting off, soil-dwelling fungi may be the cause. Make sure the soil is well drained, and avoid overwatering and/or overcrowding. Keep winter mulches away from the crowns of the plants and clean up and destroy any affected plant parts.
Companions: Campanulas are at home in the company of Lamb's Ear (Stachys), Lady's Mantle (Alchemilla), Columbine, and Roses. Their delicate form and cool colors complement many other perennials.
Reflowering: While deadheading can be tedious for the small-flowered varieties, you will be rewarded with a longer bloom season. Carpathian Harebell (C. carpatica) and C. lactiflora may be cut back by a third after flowering to promote new growth and sporadic rebloom. Serbian Bellflower (C. poscharskyana) does beautifully as a ground cover even in dry conditions and/or partial shade. Cut back to 2″ tall after flowering. You may deadhead Peachleaf Bellflower (C. persicifolia) for longer flowering but this is tedious, as each individual flower must be removed so as not to cut off new buds along the flowering stem. After bloom season, remove old flower stems down to the basal foliage.
Dividing/Transplanting: Divide Carpathian Harebell (C. carpatica) every 2–3 years in early spring, and Peachleaf Bellflower (C. persicifolia) every 3–4 years. All Campanulas may be transplanted in early spring or fall with sufficient soil and thorough follow-up watering.
End-of-Season Care: Leave basal growth on C. carpatica, C. poscharskyana, and C. persicifolia for the winter to help protect the crowns of the plants; cut back any dead or unattractive foliage in early spring. The foliage of Campanula lactiflora may be cut back to 3″ in late fall.
Calendar of Care
Early Spring: Apply a light application of 10-10-10 fertilizer or side-dress with compost and organic amendments when new growth appears. Supplement nitrogen during periods of prolonged rain to counter natural leaching. Water well if it is unseasonably dry, as plants prefer evenly moist soil. If rust diseases were present during the last growing season, treat plants with wettable sulfur to prevent recurrence. Divide Carpathian Harebell (C. carpatica) every 2–3 years, and Peachleaf Bellflower (C. persicifolia) every 3–4 years.
Mid-Spring: Watch for aphid infestations and spray them with insecticidal soap. Monitor plants for signs of slug activity and control pests if present. Mulch plants as soil warms to buffer soil moisture and temperature.
Late Spring: Taller forms may need staking, especially if grown in partial shade. Watch for blackening basal foliage or sudden wilting indicating crown rot and treat as necessary, being careful to remove and destroy dead leaves or stems. If orange or reddish-brown pustules appear on the undersides of leaves, rust disease is present. Remove infected plant parts and cut back foliage as needed if disease is disfiguring.
Summer: Pinch off dead flowers to encourage longer bloom period. Small, sharp scissors may be used to deadhead the small-flowered forms like C. carpatica. Groom plants by removing yellow or dead leaves. Alternatively, cut C. carpatica and C. lactiflora back by one-third after flowering. Water during dry periods.
Fall: Cut the foliage of Campanula lactiflora varieties back to three inches above soil level. Stems and leaves of C. carpatica, C. persicifolia and C. poscharskyana may be left intact over the winter.
