visitation attempt at the CFC in 2016 and 2017 define out to tax the potential of ornamental grass as a ‘ seasonal filler ’ to bring social organization and bulk to cut flush bouquet . The grass species try included : Bromus macrostachys , B. secalinus , Chasmanthium latifolium , Eragrostis elegans , Panicum elegans ‘ Sprinkles ’ , P. miliaceum violaceum , Setaria italica ‘ Max ’ , S. pumila glauca , Sorghum nigrum and Stipa capillata ‘ Lace Veil ’ .
Sowing and plantingInitial trial run investigated the potential of unmediated drilling seed into the soil and the use of plug - raise plant , originate both under Spanish burrow and outdoors . hoopla plants were planted under aegis during week 16 - 17 , at a density of 25 and 64 works / m2 , and outside in calendar week 17 at the same denseness . The direct drilling trial was sown in week 18 and 28 , seedlings were thinned to approximately 64 plants / m2 .
All of the grass species grew aside smartly , with the stopper plants under protection produce vendible stems within 10 weeks , however , the outdoor fireplug plants were damaged by Robert Lee Frost just after planting . The early seeded player sown crop was ready after 14 week whereas the later sowing only took eight week . The trials demonstrated that early direct drill harvest can take up to four weeks longer to senesce than tantamount plug plant crop , but the difference appears to lessen with later seeded crops , and that the low industrial plant density trialled was the most suitable for give rise the best quality flower stems .
trial run staged the following twelvemonth focus on Bromus macrostachys , Eragrostis elegans , Panicum elegans ‘ Sprinkles ’ , P. miliaceum violaceum , Setaria italica ‘ Max ’ , S. pumila glauca and Sorghum nigrum . One of the trial objectives was to enquire the electric potential for cropping continuity using three different planting dates under shelter , these were weeks 21 , 25 and 30 . Direct boring was also investigated again , but as germination from the calendar week 14 sowing was erratic , it was make up one’s mind to only use plug plant for the residual of the trial run . The crops were ready for harvesting within eight to 10 calendar week of planting , the single direct - practice crop accept an extra four week . The trials indicated that persistence of provision could be achieve by the exercise of successive planting ( or sowing ) see with a weekly or fortnightly separation being ideal .
Precise seeding rates for the different locoweed species need to be obtained from the relevant seed suppliers . As with all outdoor cold shoulder flower crops , the commercial success of direct - exercise ornamental grasses will be decide by the prevail weather conditions , but indication are that if well water , an outdoor crop will get short ( but still commercially satisfactory flower stems of 55 curium or more ) and more robust stem turn than those generated by plant under protective covering .
HarvestingThe harvest home stage of the product will depend upon the supergrass mintage uprise and the agreed customer specification , but in broad term the flower head should be harvested as shortly as the individual florets become visible and before any desquamation of pollen go on .
The most cost efficacious manner of harvesting smoke is once over , when the whole craw is harvested at the same time and sort and scoring follow on a flower melodic line in the packhouse . Regular sequential plantings ( or sowings ) of the crop are essential to ensure the success of once - over harvesting . Yield will depart by pasturage species , but information from the Netherlands indicates a glasshouse - produce crop of Panicum virgatum can bring on up to 10 - 15 blossom stems / plant .
intersection shelf lifeDuring 2016 , samples were harvest and set into buckets of piss containing either Chrysal RVB Clear Intensive ( 1ml / L ) or Chrysal CVBN ( 1 tablet/2L ) as a water discussion , before being transferred to a vase life facility for two days at 2 ° cytosine to simulate the transit phase angle in the supplying chain . After two days , the stems were recut , placed in a solution of Chrysal Professional 2 T - Bag and put into a vase life history elbow room for three days to assume retailer stipulation . The home vase life phase then commenced afterwards for a further seven day .
Bromus macrostachys , Eragrostis elegans , Panicum elegans ‘ Sprinkles ’ , P. miliaceum violaceum , Setaria italica ‘ Max ’ , Sorghum nigrum and Stipa capillata ‘ Lace Veil ’ were all subjected to the standard vase life testing . All sample were still in an satisfactory condition by mean solar day seven of the home vase lifetime examination phase angle . By this stage some folio of Bromus macrostachys , Panicum miliaceum violaceum and Setaria italica ‘ Max ’ were yellowing or showing symptom of dehydration , but not to the extent that would have leave in loser of a mixed fragrancy . small or no shedding of anther or pollen was seen . The results indicate that all of these grass species have potentiality for use in mixed redolence with up to a seven daylight guarantee .
