Q: How does 'Gulf Stream' differ from other popular Nandina cultivars?
A: 'Gulf Stream' is distinguished by its naturally symmetrical, upright habit (3-4 ft) and unique blue-green summer foliage that transitions to fiery red in winter. Compared to 'Moon Bay' (more mounding, lime-green new growth) and 'Nana Purpurea' (purple-tinged foliage), 'Gulf Stream' offers a more formal, upright structure and a distinct blue-green summer color phase .

Q: How much sun does it need for the best winter color?
A: For the most intense red winter coloration, plant 'Gulf Stream' in full sun. In shadier locations, the foliage will be predominantly green with less dramatic seasonal change .

Q: How should I prune it to maintain its shape?
A: 'Gulf Stream' requires minimal pruning due to its naturally symmetrical form. If needed, prune in late winter or early spring to remove any dead or wayward stems. To rejuvenate an older plant, cut a few of the oldest stems to the ground to encourage fresh new growth .

Q: Is it considered invasive?
A: While standard Nandina can be invasive in some regions due to seed spread, 'Gulf Stream' is a cultivated variety that produces fewer berries than the species, reducing its invasive potential. However, it may still produce some berries and self-seed occasionally in ideal conditions .

Q: Are the berries and foliage toxic?
A: Yes, all parts of Nandina contain cyanogenic glycosides and are considered toxic if ingested in large quantities. The berries, in particular, pose a risk to birds and pets. Plant with caution where pets or small children may be tempted to eat them .
