Persian Buttercup 'Aviv' yellow
Europe & Asia
Ranunculus, also known as buttercup, comes in various colours from bright pink, red, and purple to cream, pale yellow, and orange and each colour carries a particular meaning with itself. Yellow ranunculus stands for bedazzled. This flower is ideal for those who want to express their love to their beloved.
Ranunculus asiaticus yellow bulbs will produce vivid yellow fully double flowers with tightly clustered petals. Aviv Ranunculus produce 8-10 peony shaped Large flowers measuring 4-5" across on 12-16" stems . The herbaceous plant reaches heights of 20 to 40 cm and has a slightly bushy growth habit.
Persian buttercups do well in sunny spots (at least six hours of sunlight on most days) to grow and bloom best. However, they react to too much direct midday sun by wilting flowers quickly. Ranunculuses like it cold. If the temperature gets too warm, the plant stops giving flowers and goes into ‘rest’. The energy then goes into the roots instead of the flowers.
Soil must be rich, well-drained soil. The pH level of your soil should be 6.5-7.0, slightly acidic. If you have a heavier (clay) soil, add in sand, cocopeat, or organic manure to lighten and loosen the soil texture for better drainage.
Before planting, the tubers should be placed in lukewarm water for a 30 min to 1 hours. Then you can plant the Persian buttercups 4 cm deep and with a planting distance of about 20 cm with the roots down into the ground. Plant the bulbs with the end that looks like claws facing down and cover them with one to two inches of soil.
Water the bulbs well upon planting, and then withhold water until growth appears to avoid rot. Once the plants are established, they prefer moderately moist soil, so water only when the soil begins to dry out.
Ranunculus foliage is highly susceptible to powdery mildew, so maintaining good airflow in and around the plants is critical. Use drip irrigation or water early in the day so the foliage stays as dry as possible. Avoid overcrowding the plants.
Mix some compost or bulb fertilizer into the soil of the planting site before planting your corms. If growing in a container, fertilize the plants biweekly with a water-soluble fertilizer.
It is suitable both for the flower bed and as a pot plant on the balcony or terrace.
Persian buttercup is poisonous to humans and animals. All parts of the plant contain toxic glycosides that can cause severe symptoms of poisoning, depending on the amount ingested.
The general rule of thumb for planting spring bulbs is to plant two to three times as deep as the bulbs is tall. This means most large bulbs like tulips or daffodils will be planted about 8 inches deep while smaller bulbs will be planted 3-4 inches deep. Planting depth is measured from the bottom of the bulb.
