Days To Maturity
Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Butterfly™ Hera® Ranunculus Corm
New! Unique branching ranunculus.
About the Butterfly™ Series: Developed in Japan, Butterfly™ ranunculus produces multiple branching stems per plant with 5–7 blooms per stem. Its distinctive 2–3" wide blooms more closely resemble cosmos or poppies than traditional ranunculus. The flower petals also have a thin, waxy layer that helps make them surprisingly durable and creates a sparkling, opalescent sheen on the petal's surface. The plant habit is quite different from the more widely known or traditional type of cut-flower ranunculus: Butterfly ranunculus has larger corms; tall, branching stems; larger leaves; and a vigorous plant habit that requires wider spacing. Do not pinch plants, as plants branch naturally. Unauthorized reproduction and sale of corms is prohibited by the breeder. Please Note: This crop requires very specific growing conditions; please review our growing instructions before investing in corms. Butterfly™ Series corms (tuberous roots) are not graded or sized and vary somewhat depending on variety, typically 2.5–4 cm in width and 5–6.5 cm in length. Specs:

Ranunculus corms ship in the fall, typically September through January.
Soaking: This process is essential for deeply hydrating the dry, dormant root material and initiating a growth cycle. Soak corms for 8–12 hours in water at a temperature of 77°F (25°C). Ensure that all the corms stay submerged under water for the entire soaking period.
Chilling Treatment: Chill by holding corms at 40–50°F (5–10°C) for 3 weeks after soaking. These cool temperatures can be achieved either by holding corms in cold storage or by planting directly into garden beds while soil temperatures are within the desired range. Corms chilled in cold storage can either be stored loose in peat or vermiculite or in soil in seedling trays. For more information on chilling methods, consult our Ranunculus Production Guide.
Planting and Sprouting: After soaking and chilling, corms can be planted directly into soil or as transplants. Whether in soil or in trays, this stage of sprouting and shoot development should take about 2–4 weeks in temperatures 55–60°F (12–16°C). Planting Loose Corms: To plant corms directly into the soil, place corms with the center of the corm facing up and fingers/roots facing down into the soil. Take care not to damage the roots during the planting process. Cover the corms with 1/8– 1/4" soil. Planting Corms as Transplants: after having been chilled in their seedling trays (step #2 above), grow corms at 55–60°F (12–16°C) until roots and shoots develop and plants are ready to transplant. Water trays well. Soil should remain moist but not saturated. Depending on your location, shade cloth can be used to help keep a crop cool. White plastic mulch can be used as weed barrier in addition to helping to keep the soil evenly moist and cool.
Light Preference: Sun.
Plant Height/Stem Length: Butterfly ranunculus: 18–36". Romance ranunculus: 14–24".
Plant Spacing: Butterfly ranunculus: 10–12" apart within the row, with 12–14" between the rows. Romance ranunculus: 6–8" apart within rows and 8–10" apart between rows.
Hardiness Zones: Typically grown as an annual in a tunnel or greenhouse. In USDA hardiness zones 7 and greater, ranunculus can perennialize and be grown outdoors. While established plants can tolerate light frosts, exposure to freezing temperatures is not recommended and unsprouted corms should never be allowed to freeze.
Vase Life: 10 days. Place cut stems into cold water and store at 34–40°F (1–4°C).
Harvest: Harvest flowers only early in the morning, if possible. Use a knife or snippers to cut the stem at ground level. Do not pull the stems from the bulb; this can result in pulling up or damaging the plant. Harvest window is 2–4 weeks, depending on conditions. Temperatures consistently above 70°F (21°C) may trigger dormancy in the plants resulting in a shorter harvest window and a decline in bloom quality. Butterfly ranunculus: Harvest once 2–3 flowers on the stem are showing color and 1 flower is open. Romance ranunculus: Cut blooms at the "marshmallow stage," once the blooms color-up and feel springy like a marshmallow and before they fully open. For maximum bloom size and showy flowers, allow the flowers to open and close for 3 days before harvest.
Soil Requirements: Cool, moist, well-drained soil. Ideal soil pH: 5.8–6.3; ideal EC (electrical conductivity): 1.3 to 1.5.
Pests and Disease: Both corms and plants are attractive to rodents. Protect the crop from rodent damage throughout the crop's lifecycle. Use of fungicide treatment during the sprouting process can greatly reduce chances of crop loss from root rot pathogens.
Uses: Cut flower.
Scientific Name: Ranunculus asiaticus
Alternate Common Names: Persian buttercup, Persian crowfoot, Asian buttercup
