Question
Would like something that can grow quick & bushy in a container (or series of containers); provides privacy & a screen effect - we live on a corner in outer sunset & want to enjoy the yard in private - or something that can grow on a trellis (or series of trellis)...thank you!
Hope

Answer
If you truly want a screen, you will need to accomplish it in several containers or large rectangular planters. The bigger the plants become in their containers, the more thirsty they get. The plant roots may eventually enter the ground through the drainage hole (s). The fastest and bushiest screen candidates are Pittosporum tenuifolium, Dodonaea Atropurpurea (Hopseed), Feijoa (Pineapple Guava), Callistemon (Bottlebrush), and Myrica (California waxmyrtle). Be aware that many shrubs and vines become "leggy" in containers. This is due to inconsistencies in feeding and watering as the plants become larger. Trellis options would be best planted in an espalier box. Vigorous vines are Jasminum polyanthemum (pink bud jasmine), Clematis armandii, Passiflora (Passion flower), and Bignonia (crossvine).
