Purple Porterweed Plant

Our Purple Porterweed Plant is also a medium-sized variety very similar to Lavender Porterweed, but with blossoms a much richer color of purple, and quite velvety looking. The two planted together make a very striking display. This reliable tender perennial will remain evergreen in frost-free zones, will come back from the roots when well-mulched in areas with mild winters and will almost always reseed readily.

Planting Instructions:

• - Best planted in spring or summer to ensure strong growth during the active growing season
• - Space plants 2-3 feet apart to allow room for spreading

Soil Preparation:

• - Ideal soil pH: 6.0-7.5, but tolerates a range of pH levels
• - Thrives in well-drained, sandy, or loamy soil enriched with organic matter

Watering Specifics:

• - Water regularly during the first few weeks to establish roots
• - Once established, porterweed is moderately drought-tolerant but prefers consistent watering during dry periods

Fertilizer Type:

• - Use a balanced, slow-release fertilizer in early spring and mid-summer for best results
• - Avoid over-fertilizing, as this can reduce blooming and attract pests

Pruning and Training:

• - Lightly prune to maintain shape and encourage bushier growth
• - Remove spent flower spikes to promote continuous blooming

Additional Pest Management:

• - Generally pest-resistant but monitor for spider mites and aphids
• - Maintain good air circulation to prevent fungal diseases

Temperature Tolerance:

• - Sensitive to frost; move to a sheltered location or grow as a potted plant in colder climates
