Mountain Daisy Celmisia semicordata
ABOUT
Celmisia semicordata, commonly known as the mountain daisy, is a striking perennial plant. It features a rosette of long, narrow leaves that are silver-green on the upper surface and have a distinctive white, woolly texture underneath. The leaves are prominent and can be quite long, giving a lush appearance to the plant. The mountain daisy produces large, daisy-like flowers that stand out with their bright yellow centers and white ray florets that radiate around them. These flowers bloom on solitary, upright stems and are a dramatic contrast to the silver-green foliage. The appearance of the mountain daisy is adapted to attract a range of pollinators, which are drawn to its vivid and showy flowers. The combination of uniquely textured foliage and bold flowers makes the mountain daisy a visually appealing plant.

WaterThe Mount Cook Lily should be watered sparingly, as it is susceptible to root rot if overwatered. The plant prefers the soil to be slightly moist but never waterlogged. Typically, watering once every week to ten days is sufficient, providing about half a gallon of water each time depending on the size and the pot it's in. Adjustments should be made during hotter, drier periods or in particularly humid or cool conditions to maintain slight soil moisture.
LightThe Mount Cook Lily thrives in bright, indirect light, making it suitable for placement in a location that receives plenty of natural light but is shielded from the harsh direct sun. An east or west-facing window would be an ideal spot, or a south-facing window with some shade. Avoid direct afternoon sunlight to prevent leaf burn.
TemperatureThe Mount Cook Lily prefers cooler temperatures, thriving in a range between 50°F and 75°F. It can tolerate minimum temperatures down to around 40°F but should be protected from frost. Avoid exposure to temperatures above 80°F as it may cause stress to the plant. Ensuring good airflow can also help maintain a cooler environment.
PruningThe Mount Cook Lily should be pruned to remove dead or damaged foliage and to maintain its shape. Pruning is best done after flowering, usually in late summer or early fall, cutting back the spent flower stems to the base of the plant. Pruning periodically also encourages new growth and a fuller appearance.
CleaningAs needed
SoilMount Cook Lily (Celmisia semicordata) thrives best in a soil mix that is well-draining and has some grit content, such as a mix of loam, peat, and pumice or perlite. The ideal pH for this alpine plant is slightly acidic to neutral, ranging from 5.5 to 7.0.
RepottingMount Cook Lily should be repotted every two to three years or when it has outgrown its current pot. It is important not to disturb the roots more than necessary during repotting.
Humidity & MistingMount Cook Lily prefers moderate humidity levels. It is adapted to the alpine climate where the air is crisp and not excessively humid. Avoiding high humidity that can lead to fungal issues is advisable.
Suitable locationsIndoor
Provide cool temperatures and bright indirect light.

Life cycleCelmisia semicordata, commonly known as mountain daisy or large mountain daisy, begins its life cycle as a seed that germinates in well-drained, rocky alpine soil. The seedling emerges, developing long, narrow leaves in a rosette form, adapted to the harsh mountain environment. As it matures, this evergreen perennial produces a dense clump of foliage and, in summer, tall flower stems that bear large, daisy-like white flowers with yellow centers. After pollination, typically by insects, the flowers produce seeds that are distributed by wind and gravity. The plant continues to grow and spread vegetatively as well through rhizomes, expanding its presence in the alpine meadow. Over many years, individual mountain daisies can form sizeable clumps, but they may also experience cycles of dieback and rejuvenation in response to environmental conditions such as snowpack and temperature.
PropogationPropogation time
Spring-summer
The most popular method of propagation for Celmisia semicordata, commonly known as the mountain daisy, is by seed. The best time to sow seeds is in the spring after the risk of frost has passed. Seeds should be sprinkled onto a well-draining seed starting mix and lightly covered with soil. The seed tray needs to be kept moist but not waterlogged and placed in a bright, sheltered spot but not in direct sunlight. Germination can be slow and uneven, but once the seedlings are large enough to handle, they should be transplanted into individual pots and grown on until they are strong enough to be planted out in their final positions.
