Rosybrook is a prairie apple crab, listed as a crabapple or applecrab with fruit under 5 cm across. Its recorded parentage is 'Trail' x 'Rescue'. Prairie index sources place its introduction at the Alberta Horticultural Research Center in Brooks, Alberta, in 1980. It was also singled out as a top rated hardy crabapple for the Prairie Provinces. [S1] [S2]
Sources describe Rosybrook as a crisp, sweet apple crab selected for quality and utility. A later prairie directory entry gives a fuller description: fruit about 4 cm wide, pale green but mostly covered with red, with creamy white flesh of fine texture. The fruit is firm, crisp, sweet, and mild, with no astringency. A companion trait table summarizes it as large for its class, light green with red, cream fleshed, and suitable for fresh use and processing. [S1] [S2]
Rosybrook was recommended for dessert, preserving, and cooking. Other source entries add pies, canning, and juice to its uses. It ripens in August and keeps about a month, so it appears to be an early season crabapple rather than a long keeper. One source also notes good resistance to browning, which helps explain its value for kitchen use. [S1]
Hardiness is described in two slightly different but compatible ways. The prairie recommendation list gives Rosybrook the H1 rating, the hardiest class, while the cultivar directory rates it H1-2, between very hardy and moderately hardy. Both place it firmly in the hardy prairie class. Rosybrook also stands out for its reputation as an edible crabapple: the recommendation list calls it a crisp sweet apple crab, and Sprout's remark preserved in the directory calls it a "tasty little crabapple." [S1]
