Chilean Guava – Jim Gerdemann
The Jim Gerdemann form of Chilean Guava was selected by Ian Barclay of Desert Northwest from the collection of infamous gardener and plant collector Jim Gerdemann’s garden on the Southern Oregon Coast. Jim could not remember where he got this plant from but in his honor we’ve named this selection after him. Plants have a more rounded leaf shape than the species and supposedly a bit more cold hardiness. In coastal climates or part shade the Jim Gerdemann Chilean Guava may grow up to 8 feet tall but in full sun and growing inland it usually stays around 3 feet high by 3 feet wide. Fruit is just as delicious and prolific as you’d expect from the species.
