Brushmark Cesar® Ranunculus

Brushmark Cesar® ranunculus corms produce extraordinary white blooms splashed and edged with shades of cranberry pink, rose, and purple. The contrasting markings sweep across the petals like strokes from a paintbrush, giving each flower a beautifully hand-painted appearance. Natural variation is part of the charm of this variety, with no two blooms looking exactly alike.

Order is for 5 corms.

Part of the distinctive Brushmark ranunculus series, Cesar produces large, double flowers with a slightly looser, more ruffled form than traditional ranunculus. Layers of textured petals create substantial blooms with incredible dimension, while the crisp white base makes the colorful markings especially striking.

Brushmark ranunculus are distinctive specialty cut flowers known for their beautifully patterned petals, with constrasting streaks and marking that look like they’ve been individually painted by hand. I saw these in person while visiting Europe in March and they are STUNNING!

Grown from ranunculus corms, Brushmark varieties are wonderful for cutting gardens, bouquets, and floral design. Natural variation in the markings is part of their charm, making every harvest—and often every flower—a little different.

How to Grow Brushmark Ranunculus from Corms

When to Plant Ranunculus Corms

Ranunculus are cool-season flowers that grow and bloom best during periods of mild weather. In warmer climates, corms can be planted in fall for late winter and spring flowers.

In colder climates, Brushmark ranunculus corms are typically started in late winter or early spring and planted outdoors with protection once conditions allow. Plants perform best while temperatures remain cool and generally begin to slow as consistently warm summer weather arrives.

How to Prepare Ranunculus Corms for Planting

Dormant ranunculus corms naturally arrive looking small, hard, dry, and somewhat like tiny claws. This is completely normal.

Before planting, soak the corms in room-temperature water for approximately 3–4 hours. They will begin to plump as they absorb moisture.

After soaking, corms can be planted directly or pre-sprouted to encourage earlier root development. To pre-sprout ranunculus, place the soaked corms in lightly moist potting mix and keep them in a cool location for approximately 10–14 days. Check periodically for developing roots and remove any corms showing signs of rot.

How to Plant Brushmark Ranunculus Corms

Plant ranunculus corms approximately 2–3 inches deep and 4–6 inches apart, positioning the pointed "claws" downward.

Choose a location with full sun and fertile, well-draining soil. Excellent drainage is especially important when growing ranunculus, as corms can rot if they remain excessively wet.

In colder climates, frost cloth, low tunnels, or an unheated greenhouse can provide additional protection and help extend the cool spring growing season.

Watering & Caring for Ranunculus

Water thoroughly after planting and then keep the soil lightly and consistently moist. Avoid excessive watering, particularly while the corms are developing their first roots and shoots.

Once actively growing, ranunculus appreciate consistent moisture, fertile soil, and good air circulation. Supporting plants with flower netting can help keep stems straight and protect developing flowers from wind and heavy spring weather.

When Do Brushmark Ranunculus Bloom?

Ranunculus generally begin flowering approximately 10–14 weeks after planting, although bloom time varies depending on planting date, temperature, climate, and growing conditions.

For the best vase life, harvest ranunculus cut flowers once the buds have developed color and feel soft when gently squeezed—often described as having the feel of a marshmallow—but before the flowers are fully open.

Regular harvesting encourages plants to continue producing additional flower stems.

Growing Ranunculus in Cold Climates

In colder growing zones, Brushmark ranunculus are typically grown as cool-season annuals rather than relied upon as winter-hardy perennials.

Starting corms in a protected environment in late winter can give plants a head start before they are moved outdoors. Established ranunculus tolerate cool spring conditions well, although protection may be necessary during periods of extreme cold.

What to Expect When Your Ranunculus Corms Arrive

Don't be concerned if your Brushmark ranunculus corms look small, hard, dry, and wrinkled when they arrive. This is exactly how dormant ranunculus corms should look.

Once soaked and planted, the corms begin developing roots and foliage before sending up their flower stems. With proper care, each small corm has the potential to produce multiple beautiful blooms throughout the spring season.

With their lush, rose-like flowers and distinctive painted markings, Brushmark ranunculus are an exceptional choice for gardeners and flower growers searching for unusual ranunculus varieties for the spring cutting garden.
