Luma apiculata is one of the Chilean Myrtaceae, which is planted worldwide, in many similar climates. This is because of its beauty as a tree and also for its edible fruits. Moreover, it can take some cold and is hardy to USDA Zone 9.
My container grown Arrayán flowered profusely in July, and nearly every flower set fruit. Despite, we had an unusually warm and long summer, the fruits are still not ripe yet. The fruits are slightly soft. However, ripe fruits should be black, not white.
The plant is still outside. Several slight night frosts in November, around -3° C (27°F), did not harm the plant, nor the fruits. If the nights become colder as -6°C (21°F), I will put the plant in the garage. If the day max temperatures will stay prolonged below -6°C (21°F), the plant will be moved in the basement. Because the basement is too dark and too warm, the plant will be moved outside, or in the garage, again, as soon as the weather allows. This worked in the last years. The last winters, the plant spent around a few days, up to two weeks, in the basement. About two or three times, during a winter.
Usually, Arrayán ripen in autumn. However, in the web, one can find pictures of ripe fruits and flowers on the same plant. Therefore, I hope the fruits will ripen in spring. I have picked one fruit. At the first glance, the taste was very pleasant. However, a fraction of a second later, almost simultaneously, the fruit was extremely bitter. Definitely unripe and unpalatable.
