As seen in the table below, the outcome of the grant project fell far short of expected revenue—barely more than one third of anticipated income was collected.  However, $3010 of the expected income was from species that were not planted, due to changes in the grant—before planting but after the grant was written, fibigia was found to be an unsalable crop, sources could not be found for ismene, and tuberose (polianthes) was discovered to be unsuitable for growth in areas with cool nights.  Actual revenue neared fifty percent of that expected once this was taken into account.

 

Unforeseen circumstances also affected revenue—although weather aberrations are perhaps to be expected. Record frost destroyed one species just as it was coming to harvest in the rollup, unheated house.  The foxglove was just beginning to bloom when a 22 degree night damaged all spikes. An additional $1000-$2000 dollar revenue could have been expected had the flowers been marketable.

 

Another weather failure included the Kale crop, which was found to be unsuited to fall production, even in protected, but unheated hoophouse situations. It froze in late autumn.

 

Marketing failures included dianthus, which, while a productive species, was not highly marketable in the affluent markets sold to—in more traditional and conservative markets, hoophouse production would likely be very lucrative for this cutflower. Acidanthera was another marketing disaster, blooming no earlier under greenhouse conditions than in normal, outdoor conditions, and its delicate bloom too fragile to survive shipping. It is not a good hoophouse crop.

 

Also counted among the failures were ornithogalum and freesia, which did not produce a high number of stems to bulb, with many bulbs producing only foliage.  Only 40 percent of the freesia bloomed, 30 percent of the ornithogalum. Freesia may require a longer period of cool temperatures; no explanation for the ornithogalum failure is available. Dutch iris also had a low bloom rate:  68 percent.

 

While brodiae (also known as tritelia) also had a low bloom rate, it was discovered to be a very good seller. Every stem was sold at a high profit. Convallaria (lily of the valley) also sold extremely well, though not at the price commanded by wholesalers. Most bunches were sold at eight dollars—prices of 40 and fifty dollars a bunch are not unheard of from wholesalers, but can only be achieved from special events, particularly weddings.

 

Ranunculus did not produce as expected, needing more weeks of cool temperatures for high numbers of stems to corm. However, it is highly marketable and under plastic and heated for a longer period of time would be a very profitable crop for northern growers.

 

Escholtzia (California poppy) was a prolific species, and while very salable, produced more than the local markets could bear. It is a very lucrative and easy crop with a long bloom period.

 

The anemone crop was disappointing, perhaps due to close spacing. Blooms were not as attractive or as large as that brought in from California sources. It deserves further exploration as a cut crop in the north, however, for it has a long bloom window and flowers prolifically.

 

Lobelia was an excellent seller, and met expectations. Less was planted than intended, due to supplier failure, but it produced and sold well. One variety, “illumination”, proved to be less than prolific—one stem per plant—and susceptible to spider mites, but otherwise the crop was a success. 

 

Oxypetalum (tweedia) produced only about one stem per plant. It should be planted earlier than it was in the grant project, for it needs a long period of cool weather. It sold well, and florists commented on the fine quality in comparison to that shipped in from outside sources.

 

Delphiniums were a failure, due to bug pressure in bud stage. Most stems were deformed and unmarketable. It would be a good hoophouse crop, however, if insects can be kept at bay.

 

Zantedeschia (calla lily) was both a success and a failure. The large flowering types, planted in the heated, small greenhouse, produced far less than the small flowering types planted in the unheated rollup. It is believed that the supplier of the tubers treated the small flowering types with gibberellic acid, but failed to do so  for the large flowering types (gibberellic acid is a growth hormone commonly used to increase bloom numbers).  Every stem was sold at a relatively high price ($1 per stem for large, 75 cents for small), giving a return that almost doubled the cost of the bulbs, making it one of the more successful species of the grant project.   The tubers can be re-used in following years if dug up and stored—then treated with gibberellic acid before re-planting.

 

The project took far more hours of labor than expected, 850 hours—300 were expected.  Mileage of 11304 was higher, too.  At 32 cents per mile, the project routes cost $3617.28—slightly more than the 3500 dollars anticipated, without paying the driver. These were in-kind contributions, paid for by the grant recipient.

I would like to thank the Idaho Department of Agriculture for the opportunity to undertake this research project.  It will aid my future growth as a cutflower farmer, and hopefully add to the state’s possibilities as an agricultural entity. I will be glad to share my experience with others.
