We've grown a few Rosemary cultivars here but several have been removed to comply with planting guidelines at that time. We still have S. Golden Rain and this one pictured here. It is very large. About six foot tall and over ten feet wide with annual trimming of two sides were it encroaches on walkways. The trimming exposes a tangle of woody branches for months as it grows back. Not an attractive look. Trimming should be done frequently to keep it contained and always attractive. Can be used for a topiary too. There are smaller cultivars too with flower colors from deep blues to white and pinks. These are really floriferous and the bloom starts in January here and great for the bees. I use the sprigs for cooking of course. There very very drought tolerant. Ours are in raised plots with very well draining sandy soil that is amended and mulched periodically.
