Scaevola plant care

Fan flower is low-maintenance and easy to care for. Follow these plant care tips for best results.

Temperature and sunlight needs for fan flower

Scaevola likes at least 6-8 hours of sun a day. Some relief from hot afternoon sun is appreciated. Note that plants grown in shade will not flower as profusely.

Since these plants are native to Australia, they will grow well in warm and hot weather. If the temperatures fall below 60° F, they will slow down or even stop flowering.

Fan flower likes day time temperatures between 70° F and 85° F best, and temperatures of about 68° to 70° degrees F at night. High humidity is beneficial.

The thick stems ensure drought tolerance in full sun locations, even in triple digit temperatures.

Plant scaevola in the spring when the danger of last frost has passed and soil temperatures reach 65 ºF. Space them 12-18 inches apart to give the plant room to spread.

Watering requirements for scaevola plant

Scaevola is both heat and drought-tolerant which accounts for its appeal to gardeners.

Don’t over-water fan flower. Water and then wait until the surface of the soil is dry before watering again.

Plants left to sit in wet soil can attract fungus gnats and may be susceptible to root rot.

If you notice that your fan flowers are wilting, just give them a drink. This will quickly revive them.

A layer of mulch will help the soil retain moisture and reduce the chances of weed growth.

Fertilizing and soil needs for fan flower

Scaevola is not particular about the type of soil that it is grown in, as long as it has good drainage. A mix of normal potting soil with added sand is good for container plants.

If your soil is particularly heavy or clay-like, compost or other organic matter can be added to make it drain better.

The ideal soil pH for scaevola is acidic. (5.5-6.0)

Scaevola plants require only light feeding with a well balanced fertilizer once a month during the growing season.  Do not use fertilizers that have too high a phosphorous level. (the middle number of the trio of nutrients.)

Iron sulfate deepens the flower color when used as a fertilizer.

Scaevola flowers and foliage

The flowers of a scaevola plant look as though they have been cut in half. The generic nickname “half-flower” means left handed in Latin. If scaevola is grown in a hot and humid climate, it produces a display of pretty fan-shaped flowers consistently from early summer until the frost hits.

Fan flower is a sprawling plant with lanced-shaped or oval light green leaves with slightly toothed margins on trailing stems.

The bloom time for fan flower is late spring through fall.

The dainty fan-shaped flowers of scaevola have five petals. They are most commonly blue but can also be purple, pink and white. Luckily for those who don’t like to deadhead, fan flower is self-cleaning.

The flowers are about 2-inch in size. If the plant becomes leggy, pinch back the stems to maintain a compact growth habit.

Growth habit and mature size of fan flower plant

Scaevola is fast-growing plant and will reach a size of 9–18 in. tall, and 1–2 ft. wide.

The plant has a sprawling habit which makes it spread easily and also makes it a good choice for ground covers, rock gardens or hanging baskets.

Fan flower can get spindly as the summer progresses. Force it to grow more thickly by pinching back the stems. It may need hard pruning by mid summer to stay bushy.

Use the pruned stem cuttings to propagate scaevola.

Problems, diseases and insects that affect scaevola

Scaevola plants are generally problem-free and they do not normally suffer from pests and diseases. If your plant fails, it is likely due to over watering or poor soil drainage.

Mealybugs can occasionally be spotted on scaevola, and too hot temperatures may attract thrips.

Be careful of spraying fan flowers with pesticides for insects. Scaevola is a good source of nectar for butterflies.

Scaevola propagation

Scaevola is normally purchased as a seedling in the spring once the soil temperatures have fully warmed up. You can also grow scaevola from seeds started indoors in very early spring.

When sowing seeds indoors, make sure to maintain a temperature between 70° to 75° degrees Fahrenheit until they take root. This can be anywhere from 30-60 days.

If you’re planting scaevola seeds outdoors, make sure that the soil has warmed sufficiently and there is no risk of frost.

Once you’ve planted the seeds, cover them with sandy loam.
