Alpine Celery Pine Phyllocladus trichomanoides var. alpinus
ABOUT
The plant, commonly known as the mountain celery pine, presents a very distinctive appearance when compared to typical coniferous trees. Instead of the common needle-like leaves found in many conifers, it displays flattened, leaf-like structures that are actually modified branches known as phylloclades. These phylloclades are arranged in a spiraling pattern around the stems, giving the impression of a whorled, tiered formation. In color, the phylloclades are a rich green, contributing to a dense, bushy look that may remind one vaguely of celery, hence the common name. The edges of these leaf-like structures are often slightly wavy, providing a textural quality to the foliage. During certain times of the year, the plant produces small, inconspicuous flowers that might be easily overlooked. Following the flowering period, it bears fruit that is small and rounded. The overall form of the mountain celery pine is irregular, contributing to its unique visual impact. Its bark is another distinguishing feature, with a rough and fibrous texture that adds to its rugged character. This bark tends to be a dark brown color, which contrasts nicely with the green of the phylloclades. The plant has a tendency to branch out, creating a somewhat spreading habit that can give it a picturesque, almost sculptural quality. While I must refrain from discussing the specific dimensions of the mountain celery pine, it's essential to understand that the plant's size is a defining characteristic, influencing how it occupies space and presents itself visually in the landscape. The proportions of its branches and phylloclades contribute to its overall appearance, which can be quite striking in its natural habitat or when used in ornamental plantings.

WaterThe Alpine Celery Pine should be watered thoroughly whenever the top inch of the soil feels dry to the touch, typically about once a week depending on environmental conditions. It's vital to water the plant slowly, allowing the water to seep down to the roots rather than just wetting the surface. For a potted plant, use approximately half a gallon of water to ensure deep watering. During the growing season in spring and summer, you may need to water more frequently, but always check the soil moisture level first to avoid overwatering. Cut back on watering during the winter months when the plant is dormant.
LightThe Alpine Celery Pine thrives best in bright, indirect light or partial shade. A spot that receives filtered sunlight for most of the day is ideal. Direct, intense afternoon sun can be too harsh and should be avoided to prevent leaf scorch.
TemperatureThe Alpine Celery Pine prefers a cool to moderate temperature range and can withstand occasional dips down to about 20°F but should not be exposed to prolonged freezing temperatures. Ideally, maintain temperatures between 45°F and 65°F for optimal growth. Avoid placing the plant in locations where it may be subjected to sudden temperature changes, such as drafts or heating vents.
PruningPruning the Alpine Celery Pine is generally done to maintain its shape, remove dead or damaged branches, and encourage new growth. The best time to prune is in late winter or early spring, just before new growth begins. Pruning lightly every year or two is sufficient. Clean cuts should be made just above a lateral branch or bud.
CleaningAs needed
SoilThe Alpine Celery Pine thrives in well-draining soil with high organic content; peat moss, loamy soil, and perlite mix well to create the ideal substrate. They prefer slightly acidic to neutral pH levels, around 5.5 to 7.0.
RepottingAlpine Celery Pine does not require frequent repotting; it can be repotted every 2-3 years to replenish the soil and accommodate root growth.
Humidity & MistingAlpine Celery Pine requires moderate humidity levels, ideally ranging from 50% to 70%, to mimic its natural forest habitat conditions.
Suitable locationsIndoor
Use bright, indirect light and ensure high humidity.

Life cyclePhyllocladus trichomanoides var. alpinus, commonly known as mountain toatoa, begins its life cycle with seed germination, where the seeds establish themselves in suitable soil conditions, often in cool, temperate climates with adequate moisture. The seedlings then develop into juvenile plants with phylloclades taking the role of leaves for photosynthesis. As the mountain toatoa matures, it forms a woody stem and bark, growing into a small to medium-sized tree. During its reproductive stage, mature trees produce cones—male cones releasing pollen and female cones developing seeds after pollination. The pollinated cones eventually release seeds back into the environment, continuing the reproductive cycle. The plant has a slow growth rate and can live for several centuries, with individual trees undergoing cycles of dormancy and growth that correspond to the seasons.
PropogationPropogation time
Spring-Early Summer
Propogation: The Phyllocladus trichomanoides var. alpinus, commonly known as alpine celery pine, can be propagated through seed collection and sowing. The most popular method involves collecting ripe cones in the summer when they begin to disintegrate, which typically occurs from January to April in their native Southern Hemisphere locales. Seeds should then be extracted from the cones and sown in a well-draining, sterile seed mix. Adequate moisture levels must be maintained, without waterlogging the seeds. The seeds of alpine celery pine may exhibit dormancy, and therefore it can be beneficial to stratify them at around 39 degrees Fahrenheit (4 degrees Celsius) for one to three months to promote germination. Seedlings will require nurturing in controlled environments, such as cold frames or greenhouses, for the first year before planting out into their permanent positions.
