Campanula Champion Pro
Inventory is limited and will be discontinued.
This Campanula medium behaves as an annual (although the rest of its species are biennial). People have trouble with this crop because it has a strong day length response. Below 12 hours of daylight, it remains vegetative, and above 12 hours, it initiates bud, regardless of how established it is. (Thus the talk of it flowering in the plug tray, or on 2" stems when planted late in the season). Early planting is recommended to let it establish before natural day length triggers flowering. It would be worth experimenting with blackout fabric to provide long nights (thus short days) until the plant has bulked up enough to support long stem growth. This crop would be best grow in the tunnel for northern growers, as your ground may otherwise be frozen at the ideal planting time.
Fall planting is recommended for mild winter growers.
Champion Pro blue seems more prone to bolting than the rest of the series or the Champion series. Any amount of stress or warm winter weather may trigger flowering.
Best results will occur when planted between week 40 in the fall and week 10 in the spring.
Champion Pro has smaller flower in a greater abundance as compared to Champion. Both are desirable and very long lasting. Cut just before buds open. Bred by Sakata.
Grown in a 216 tray, billed as a 210.
Order 7 or more weeks in advance of desired ship date.

About Tray Sizes
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 equivelent of one full sized tray. Six of these will fit in a shipping 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.
