Velvety, wave-like blooms in luminous violet—each petal edged with a soft, darker halo—spill in a cascading curtain that feels almost luminous at dusk. Wave Purple’s trailing habit forms a dense, spreading mound of color with a satin-smooth flower texture and a steady, garden-filling display through the season. Ideal for bedding and hanging baskets where you want a continuous ribbon of purple bloom for borders, walkways, and patio planters.

Frequently Asked Questions

How often should I water Wave Purple petunias during active growth?
During the main growth period, keep the root ball evenly moist but never waterlogged; water when the top 1 inch of soil feels dry. In full sun heat, this can mean daily checks and watering most days, especially in containers. If buds and leaves droop from dryness, water thoroughly until excess drains, then let the top layer dry slightly before the next watering.
How do I know when Wave Purple petunias are ready to harvest (and what counts as “ready”)?
Petunias (Petunia × atkinsiana) are grown for flowers rather than harvested fruit or leaves, so “ready” means the plant has formed quality blooms about 70 days from sowing. Start harvesting/cutting individual stems when flowers are fully colored and open, and remove spent blooms promptly to encourage continuous flowering. If you’re saving seed, harvest when seed pods turn tan and dry and the seeds easily release from the pods.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 60°F for reliable germination and early growth.

Expert Note

Start petunia early indoors and keep seedlings evenly moist with bright light—cool nights and low light cause leggy growth.
