Campanula takesimana (32)
A vigorous Korean bellflower that forms spreading clumps up to 30" tall and wide in its second year. Produces semi‑double, downward-facing, flared trumpets in shades of soft pink to dusty lavender to white from May to July; hardy throughout zones 4 to 8. Prefers full sun to part shade and moist, well‑drained soil; low maintenance and divides well. It will continue flowering if you keep on top of harvesting and deadheading. This is a great novelty cut flower for the local market that your customers and florists won't have had access to in the past. Cut stems last up to 2 weeks in the vase and add a unique spin to arrangements, especially when cascading over the edge of the vessel.
*We don't have great photos of this moody looking beauty just yet. The first photo is of the single form of the species, and the second is from Jelitto, the seed supplier.
Please note that perennial orders must be placed separately from other plug orders. The minimum order is two trays, which may be mixed and matched with all other perennials in this collection. Learn more about our perennial program here.
About Tray Sizes (please read)
210 and 125 cell trays are full-sized trays, and three of these will fit in a shipping box.
50 cell trays are half-sized trays (unless otherwise noted) and two of these are the equivalent of one full sized tray. Six of these will fit in a shipping box. These trays are long and skinny. (Think hotdogs). There are not compatible with 25 cell half trays. Scoop scabiosa, veronica, solidago, gypsophila, hypericum, herbs, some tweedia, and others are grown in the 50 cell tray.
*Chrysanthemums are grown in the same 50 cell half tray as mentioned above, but due to their height, they take up twice as much space. So TWO half trays of mums takes up 2/3 of the box.
25 cell half trays are also half-sized trays, but they are short and square. (Think hamburgers). These are not compatible with 50 cell half trays. Limonium and astrantia are grown in this tray.
Gerberas are also grown in a 25 cell half tray, but are tall that the others, and FOUR of these half trays of gerberas fills a box.
18 and 32 cell trays are full sized trays specifically for our vernalized perennials. These have their own set of shipping rules (find details HERE) and cannot be combined with items grown in 210, 125, or 50 cell trays.

| Common Name | Korean Bellflower |
| Genus | Campanula |
| Species | Campanula takesimana |
| Family | Campanulaceae |
| Life Cycle | Perennial |
| Format | 32-cell plug tray |
| Plug Care | Harden off and transplant plugs immediately upon arrival. Plant at the same level as it was growing in the plug trays, firm soil gently around plugs and water thoroughly. Maintain even moisture until established. |
| Netting / Staking | Not typically required; plants have sturdy stems. |
| Temperature Range | Hardy in USDA Zones 5-8; prefers cool to moderate climates. |
| Spacing | Space plugs 18-24 inches apart to accommodate mature plants and ensure good airflow. |
| Soil Preference | Well-drained, fertile soil with moderate moisture is ideal. |
| Day Length | Long-day flowering plant. Prefers full sun but will handle part-shade, especially in warmer climates. |
| Pinching | Not necessary; deadheading spent flowers encourages prolonged bloom. |
| When to Plant | Transplant plugs in spring after risk of frost has passed, or in the fall with at least 6 weeks of establishment time before the first hard frost. |
| Harvesting | Expect flowers in early to mid summer. Cut stems right to the base of the plant when some flowers are open but some buds remain, to continue opening in the vase. |
| Post Harvest Care | Cut stems should be immediately placed into a bucket with fresh, cool water and left somewhere dark and cool to hydrate before use. The use of a floral conditioner will help prolong vase life. Expect a vase life between 1 and 2 weeks. |
| Diseases / Insects | Watch for powdery mildew, slugs, and aphids. Maintain good airflow and avoid overhead irrigation to reduce foliar disease risk such as rust. |
| Bailey's Notes | This is a great novelty cut flower for the local market that your customers and florists won't have had access to in the past. Cut stems last up to 2 weeks in the vase and add a unique spin to arrangements, especially when cascading over the edge of the vessel. Some sources in warmer climates noted that can spread vigorously, so pull unwanted rhizomes and do not let plants go to seed to control the spread where this might be a concern. |
