Additional comments: Trailing indigo bush is a vigorous spreader, not for small spaces less than 10 feet in diameter! It is often mistakenly planted in small spaces and as a result needs much pruning to contain. Remember, this sprawling shrub MUST have a well-drained soil! Trailing indigo bush achieved its zenith of popularity during the 1990s. Currently, it has faded into the background of other 'desert landscape plants for Phoenix'.
