| Family Common Name: | Mangosteen | ||
| Scientific Name: | Hypericum frondosum Michx. | ||
| Common Name: | cedarglade St. Johnswort | ||
| Species Code: | HYFR | ||
| Ecotype: | central Tennessee | ||
| General Distribution: | Cedarglade St. Johnswort is common in the southeastern states of Tennessee, North and South Carolina, Georgia, Florida, Alabama Mississippi, Louisiana, and Texas. It has also been reported in Kentucky, Virginia, Indiana, New York, Connecticut, and Massachusetts. | ||
| Known Invasiveness: | None | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 1+0 container | ||
| Time To Grow: | 1 Year | ||
| Target Specifications: | A second spring seedling ranging in height from 6" to 18" and having a compact, well developed root system. | ||
| Propagule Collection: | Mature fruit was hand harvested from populations of Hypericum frondosum growing within the confines of USDI-NPS controlled properties. | ||
| Propagule Processing: | Mature (ripe) seed can be hand stripped from the plants or entire seedhead may be clipped. Seedheads were broken apart using a hammermill. Seed was cleaned using a rubber roll huller to remove outer seed covering. | ||
| Pre-Planting Treatments: | None required. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Commercial potting soil was moistened and placed in heavy plastic trays. The soil was compacted somewhat to prepare a firm seedbed. | ||
| Establishment Phase: | Seed was spread evenly by hand on the soil surface and then covered with 1/8 to 1/4 inch of additional soil. The top layer was pressed down slightly to ensure good seed to soil contact. Trays were then moved into a greenhouse maintained at a minimum of 65degrees Fahrenheit and natural lighting to facilitate germination. | ||
| Length of Establishment Phase: | 14 - 21 days | ||
| Active Growth Phase: | Once the seedlings had developed sufficient root systems, they were transplanted into 1 gallon plastic pots filled with commercially available growing medium. Transplants were maintained at a minimum of 65 degrees Fahrenheit in the greenhouse under automatic watering and natural lighting. | ||
| Length of Active Growth Phase: | 6 - 9 months | ||
| Hardening Phase: | Plants were moved into a shadehouse which provided a minimum of 50 percent shade to allow for hardening off before shipping. | ||
| Length of Hardening Phase: | 2 weeks minimum | ||
| Harvesting, Storage and Shipping: | Plants with sufficient top growth were loaded on trailers and shipped back to the USDI-NPS controlled properties. Trailers were covered with tarps to prevent wind burn. | ||
| Length of Storage: | 7 - 14 days | ||
