Gracious is listed as a plum cultivar under Prunus spp. in a University of Minnesota source, with an introduction year of 1957 and a source citation to Brooks and Olmo, 1997 [S1].
The available evidence is mostly experimental data rather than a descriptive cultivar profile. In germination trials, Gracious showed significant differences between non-scarified and scarified seed in Experiment II, with mean germination times of 2.4 weeks for non-scarified seed and 1.9 weeks for scarified seed [S1]. Field storage data reported 25.0% germination at 25 months and 54.2% at 1 month [S1].
In Experiment III, Gracious had 73% survival in the greenhouse and 80% survival in the field at the end of the trial [S1]. It also produced root suckers in both settings: 4 of 14 greenhouse replications produced 6 suckers, while 1 of 12 field replications produced 1 sucker [S1].
Summary source basis
This summary currently draws chiefly from Minnesota #1695.
Featured source descriptions
“Within the plums 'Gracious', 'Superior', and 'Winona' there were significant differences between non-scarified and scarified seed for average number of weeks for germination (Table 3).”
— [1]
“There were significant differences between non-scarified and scarified seed for percent germination in the greenhouse environment of Experiment II (Table 4).”
— [1]
“Table values indicate initial height 17.5 cm, initial stem diameter 1.78 mm, change in stem diameter 1.69 mm, and ΔTCA 10.43 mm².”
— [1]
“Replications of seedlings from 'Gracious' germinated in the greenhouse produced one or more root suckers during the experiment.”
