Blue Tit presents a fascinating instance of hybridization between a Green Gage and a Czar plum. In this particular case, the outcome distinctly leans towards the plum spectrum rather than retaining gage characteristics. One could argue that Blue Tit represents an enhanced iteration of Czar, showcasing similar commendable traits such as reliability, self-fertility, and prolific fruiting. Although categorized as a culinary plum akin to Czar, Blue Tit, when fully ripe, incorporates some of the gage-like flavors from Green Gage, rendering it a delightful dessert plum. It's worth noting that Blue Tit, while sharing Czar's excellent attributes, is slightly less hardy and, like many gages, thrives in a sheltered, sunny environment.
