Munro's globemallow [ Sphaeralcea munroana (Douglas) Spach] (Malvaceae), a herbaceous perennial endemic to the Great Basin of western North America, is an important candidate for use in horticulture and restoration. This species is able to tolerate
Interest in native plant species for general landscape planting, mitigation of environmental impact and ecological restoration plantings continues to expand with public awareness of environmental quality. An expanding area of opportunity exists for the landscape horticulture industry to supply non-traditional plant materials to support landscape planting with native species. To capitalize on the opportunity, horticulture and landscape architecture students and practitioners must become knowledgeable of species native to their region. Video is a useful medium for increasing such knowledge. This presentation will review the development, production, distribution and content of six video programs that survey the native herbaceous flora of Indiana prairies and woodlands. Each program is less than 30 minutes in length, to facilitate classroom use and presentation in broadcast formats. Botanically correct nomenclature is presented graphically as each species is introduced. The narration includes botanical, ecological and horticultural information, but emphasizes plant lore to increase interest for general audiences and provide memory clues for those attempting to learn the plants. This project, supported by the Indiana Association of Nurserymen, provides a good example of how horticultural industries can become leaders as the public expands its demand for improved environmental quality.
Purpletop [Tridens flavus (L.) Hitchc.] and big bluestem (Andropogon gerardii Vitman) are incorporated into native grass seed mixes for use in ecological restoration. Alleviation of low seed vigor and poor stand establishment would benefit the restoration process by increasing the animal habitat in restored zones. This study determined the effectiveness of prechilling with distilled water (dH2O) versus potassium nitrate (KNO3), sodium hypochlorite (NaOCl) treatments, and short-term storage conditions on seed germination, seedling growth, and stand establishment of purpletop and big bluestem. Prechilling of ‘Niagara, NY Ecotype’ big bluestem for 7 days at 5 °C in dH2O increased final germination percentage (FGP) and germination rate provided caryopses were not dried before sowing. Optimal FGP, germination rate, and germination synchrony were obtained for ‘VA Ecotype’ purpletop after prechilling for 14 days at 5 °C in dH2O without subsequent caryopsis drying or at 0.2% KNO3 with or without subsequent caryopsis drying. Prechilling increased germination synchrony for purpletop but not for big bluestem. NaOCl treatments did not enhance germination or seedling vigor of purpletop or big bluestem. Using nonstored, prechilled caryopses resulted in greater root lengths than stored caryopses or nontreated controls, although optimal purpletop growth required that they be sowed moist, whereas optimal big bluestem growth required that they be dried-back before sowing. In greenhouse experiments, higher seeding rates were correlated with increased number of seedlings for nontreated or prechilled big bluestem and for prechilled purpletop, but not for nontreated purpletop, which had poor stand establishment at all seeding rates. The results indicate that prechilling of caryopses before incorporation into a warm-season grass seed mix increased seedling establishment of purpletop but not big bluestem.
