Each flower measures between 2.4 to 3.5 inches across, featuring four to six pointed tepals with softly waved margins and subtle twists at the tips.

As a member of the Integrifolia group, it flowers profusely on new growth produced during the current season. Deadheading spent blossoms or harvesting stems for indoor bouquets actively stimulates rapid branching and secondary bud formation. The sheer quantity of blooms per vine is outstanding, ensuring your garden remains blanketed in intense blue-purple color throughout the hot summer months when other perennials begin to fade.\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"20\" data-line=\"true\"\u003e--------------------------------------\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"21\" data-line=\"true\"\u003e🌿 Garden Performance\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"22\" data-line=\"true\"\u003eFeaturing a graceful semi-climbing and scrambling growth habit, this cultivar offers unlimited versatility for creative garden design. Reaching a manageable height of 4 to 6.5 feet, 'Hudson River' does not climb by twining leaf petioles as aggressively as large-flowered hybrids, making it the ultimate companion plant. Allow its flexible stems to scramble gracefully through classic shrub roses, spill over retaining walls, or weave through perennial borders. It also shines brilliantly in patio containers or trained loosely onto low trellises, OBELISKS, and garden fences.\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"23\" data-line=\"true\"\u003e--------------------------------------\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"24\" data-line=\"true\"\u003e☀️ Plant Strengths\u003c\/div\u003e\n\u003cdiv data-zone-id=\"0\" data-line-index=\"25\" data-line=\"true\"\u003eRenowned for its robust disease resistance and cold hardiness down to USDA Zone 4 (-34°C \/ -30°F), 'Hudson River' is an incredibly durable perennial built for long-term success.
