Honestly, this 'Cousin Itt' acacia is something of an anomaly in the Pacific NW. Native to the hot, dry Australian landscape, Little River Wattle (so named because it is a small version of River Wattle acacia) may be best treated as a summer annual in our climate, as it is hardy down to only 20 degrees. That said, it's compact, fine-needled, slightly weeping foliage is so intriguing, 'Cousin Itt' acacia is a worthy addition to container planters and hanging baskets. Like all acacias, this variety does best in full sun and well-draining soil, so consider pairing this with other annuals that can handle life on the dry side, such as portulaca, lantana, or even some succulents.
