In coastal Southern California, it is important to choose plum trees with a low chilling requirement. A number of Japanese Plum varieties generally fruit well in this climate, and some are even self-fruitful (others need a different variety for pollination). Since fruit is formed on year-old wood, it is often recommended to prune these vigorous trees in the late spring or early summer (rather than in winter), especially if you are pruning to control the size of the tree.
Group of deciduous trees with stone fruit that are smooth-skinned and sweet. Standard-sized trees grow to about 25 feet tall and wide, but can be pruned to stay 10 to 12 feet tall and wide. Genetic dwarfs grow 5 to 6 feet tall.
Prized by many for their fragrance, the many varieties of English Lavender are not as tolerant of warm, humid conditions as many other kinds of lavender are. In coastal Southern California climates, they do have a tendency to be rather short-lived, but good drainage, air circulation, and annual shearing will lengthen their garden life. Lavenders need little or no fertilizer, dislike overly-rich soil, and should not be over-watered when they are established.
Orange-yellow, thin-skinned lemon with flesh that is less acidic than standard varieties. Only the "Improved" (disease-resistant) version of the Meyer lemon can now be sold in this zone. Bears year-round.
Along the Southern California coast, the main season for harvesting artichokes is mid to late spring. But if you cut the old flower stalks back after spring harvest, you can get another crop in the fall. Be sure you give plants plenty of room to grow in full sun on the coast or with a little afternoon shade in warmer inland areas. Green Globe is an old favorite that is usually available as dormant roots in winter. \'Imperial Star\' is an improved low-chill, heat-tolerant variety that you can grow from seed starting in September for harvest the next spring.
