At our garden in Veli Lošinj (at the island of “Lošinj”, a Croatian island in the north of Adriatic Sea,, one day with some hours at 0°C), this year, at the beginning of November, I expanded the garden into an "orchard" with a few specialties that are frost-resistant to around -10 ° C: Brazilian Guavas (Feijoa), Persimmons, Red and Black Mulberries, Russian plum, Yellow Peach, Indian-Banana (Asimina, Pawpaw), Caper bush (Capparis).
There are also a few "test plants" that can only tolerate frost for a short time:Avocado, Black Sapote (“chocolate-pudding-fruit”), White Sapote(“vanilla-icecream-fruit”), Tree Papaya (Babaco), Che-fruit (Cudrania tricuspidata), Caramel Berry (Leycesteria formosa) and Pitahaya(Hylocereus undatus).
And blooming plants: Rock roses, Brugmansia, Scented-leaved pelargoniums, large-flowered Hibiscus moscheutus (white, pink,red, mauve), Hibiscus coccineus, Canna, Cortaderia selloana, Strelitzia, Caesalpinia gilliesii, Helichrysum gardnerii, numerous Aloe species, etc.
Let's see what survives the rainy winter and grows and what we bring over the hot and dry summer. With a special planting method, pollen donors, special fertilizers and a lot of hope and care, it might (in a few years) be a rich harvest. Meanwhile, there are only figs and cactus fruits for jam and a number of non-fruiting citrus bushes (with calcium deficient) and a miniature Žižula-tree (Jujuba).
