  • water dropWater

    The Pointed-Petal Fritillary should be watered moderately during its growing season, typically once weekly with about 1 inch of water. The soil should be allowed to dry out slightly between waterings, but never completely. When the plant is dormant, after the foliage has died back, reduce watering significantly to prevent bulb rot. During the dormant period, you might only need to water lightly every two to three weeks, just to keep the soil from becoming completely arid. It is essential to provide good drainage to prevent water from pooling around the bulb.

  • sunLight

    Pointed-Petal Fritillary thrives in dappled sunlight or part shade. It prefers a spot where it can receive morning sunlight and afternoon shade, or filtered light throughout the day. Avoid placing it under harsh direct sunlight, especially during the hottest parts of the day, which can scorch its leaves and flowers. An ideal spot could be under the light canopy of deciduous trees that allows sunlight to penetrate through in a softened manner.

  • thermometerTemperature

    Pointed-Petal Fritillary prefers cool to moderate temperatures and can survive in a temperature range between 50°F and 70°F. It is hardy and can withstand minimum temperatures down to about 20 degrees Fahrenheit during its dormant period. However, it is not well-suited for extremely hot climates, and the bulbs should be planted at a depth of about 3 inches to ensure they are insulated against temperature extremes.

  • scissorsPruning

    Pointed-Petal Fritillary does not require regular pruning. Deadheading the faded flowers after blooming can encourage better bulb development for the following year. It is best to leave the foliage until it has completely yellowed and died back naturally, as the leaves are gathering sunlight and providing nourishment to the bulb below. Once the leaves have died back, they can be gently removed, typically in late summer or early fall.

    Pointed-Petal Fritillary requires a well-draining soil mix with added grit or sand to promote drainage, and a slightly alkaline to neutral pH of 6.5-7.5. A mix of equal parts loam, leaf mold, and sharp sand or perlite works best.

  • plantRepotting

    Pointed-Petal Fritillary bulbs should be repotted every two to three years to refresh the soil and allow room for growth.

  • circleLife cycle

    Fritillaria acmopetala, commonly known as Pointed-petal Fritillary, begins its life cycle as a bulb which lies dormant underground during the hot and dry summer months. In the autumn, with the onset of cooler and wetter weather, the bulb sends out roots and a shoot that emerges above ground, producing lance-shaped leaves. By spring, the plant develops one or more nodding, bell-shaped, greenish-yellow to purple flowers with distinct pointed petals, usually on a single stem. After pollination, often by bees, the flowers give way to a capsule containing seeds. As the seeds mature by late spring or early summer, the above-ground part of the plant withers, and the seeds are dispersed to start new plants. Meanwhile, the bulb enters a period of dormancy to survive the summer until the cycle begins anew with the cooler weather of the next autumn.

  • sproutPropogation

    • Propogation time


    • Propogation: Fritillaria acmopetala, commonly known as Pointed-Petal Fritillary, is typically propagated by dividing its bulbs after the foliage has died back, usually in late summer or early fall. The most popular method involves gently lifting the mature bulbs from the soil using a garden fork, being careful not to damage them. Once out of the ground, the offsets, which are the small bulbs that form around the base of the parent bulb, can be separated by hand. These offsets can be immediately replanted about 3 inches deep (approximately 7.6 cm) and at least 6 inches apart (around 15.2 cm) in well-drained soil with some added compost to provide the necessary nutrients for growth. It is important to position them with the pointy end facing upward. After planting, the area should be watered thoroughly to help establish the young bulbs. It's worth noting that the offsets may take a couple of years to flower.
