'Amethyst' is a fast-growing, lavender-purple flowering vine that is exceptionally well-suited for the Houston climate. It loves our humidity and summer heat, quickly covering fences, trellises, or arbors. While it is adaptable to many garden soils, it performs best in a well-drained environment. In areas with heavy clay that tends to hold water, we recommend planting in a raised bed or amended mound to prevent root rot during our heavy rain cycles. Note: This plant is a favorite of butterflies, so expect some leaf munching by caterpillars!
Exposure
Full Sun to Partial Shade (Full sun for best blooms)
Height x Width
10-15 feet tall x 3-5 feet wide
Water
Regular watering is necessary to establish; once mature, it has moderate drought tolerance but prefers consistent moisture.
Zones
8 - 11
Fertilization
Feed with a balanced, slow-release fertilizer in early spring and again in mid-summer.
Pruning
Prune in late winter or early spring to control size and remove any frost-damaged growth.
