|Family Scientific Name:
|Family Common Name:
||Dichanthelium clandestinum (L.) Gould
||Shenandoah National Park, Virginia, Skyline Drive
||Dichanthelium clandestinum ranges from Nova Scotia and Quebec west to Kansas, Missouri, and Oklahoma, and south to northern Florida and Texas; it prefers moist conditions but somewhat sandy soils and is found in thickets and wooded areas.
|Time To Grow:
Root System: Full, firm plug which leaves no loose soil when pulled.
||Collected in Shenandoah National Park, Virginia, by J. Englert on 8/20-21/92 and the National Plant Materials Center, Maryland, by D. Dusty on 10/1/96, 10/24/97, and 9/28/98.
||Seed Processing: Seeds are separated from chaff with a 2-screen seed clipper.
Germination: No test results. Greenhouse germination was 9% of seeds planted, or71 plugs per gram of seed.
|Growing Area Preparation/
Annual Practices for Perennial Crops:
Propagation Environment: Greenhouse with alternating day/night temperatures (75/68F) and 12-14 hours of daylight extended with high-pressure sodium lights.
Container Type and Volume: Seeds are sown in 392 plug trays. Seedlings are transplanted to 72 plug trays.
Growing Media: Seeds are sown in Fafard Germinating Mix. Seedlings are transplanted into Sunshine #5 plug mix with 180 day Nutricote (16-8-8) SR fertilizer incorporated @ 0.15lb/cu ft.
||Sowing Date: February for spring planting; July for fall planting.
Sowing/Planting Technique: Seed is surface-sown on germination mix in 392 plug trays, placed on heat mats (set @ 7SF) and misted for 5-7 days. Trays are then moved from mist to bench and seeds are lightly covered with germination mix.
Establishment Phase: Seedlings are transplanted to 72 plug flats. Appear to prefer well-drained media.
||Hardening Phase: 2-3 weeks prior to out-planting, fertilization is stopped, water is decreased and greenhouse temperatures are reduced or plugs are moved outdoors.
|Harvesting, Storage and Shipping:
||Total Time to Harvest: About 80 days from germination to finished plug.
Harvest Date: Out-planted in spring or fall.
Seed storage: Seed bags in seed cooler held at 40 F and 35% relative humidity Seed dormancy: Germination is improved with 5-7 days of bottom heat and mist.
