Bold Blooms, Unbeatable Performance

'Blue Boa' delivers vibrant violet-blue flowers in giant, densely packed spikes that rise above lush green foliage. Even the buds are a sight to behold—rich dusty purple and over 6 inches long—unfolding into flower clusters nearly 7 inches across. The towering, sturdy stems make this variety ideal for both garden impact and fresh-cut arrangements.

Pollinator Favorite with Easy Garden Appeal

From early summer through fall, 'Blue Boa' is abuzz with bees, butterflies, and hummingbirds, making it a top pick for pollinator-friendly gardens. And with so many flowers per stem, you'll have plenty to share between your vases and your outdoor display. If you've been thinking about starting a cutting garden, this might be your perfect reason.
