Frequently Asked Questions

Why is Scaevola such a popular choice for hanging baskets?

Its trailing habit and delicate fan-shaped blooms in blue, purple, pink, or white provide long-lasting color from spring through frost, making it especially well suited to hanging baskets and containers.

Does Scaevola need frequent watering?

Not once established — it's drought-tolerant, though it flowers best with consistent moisture rather than letting the soil dry out completely between waterings.
