Spire Cherry Prunus 'Spire'
ABOUT
Prunus 'Spire' is a deciduous ornamental cherry tree that is widely admired for its aesthetic appeal throughout the different seasons. In spring, the tree is adorned with an impressive display of pink flowers that emerge as tightly clustered buds. These buds unfurl to reveal delicate pink blossoms, which may cover the branches so profusely that the emerging green leaves might be barely visible initially. The blossoms of Prunus 'Spire' have a classic cherry blossom appearance, with five rounded petals that may have a slightly notched edge. The coloration of the blooms ranges from pale to a more vivid pink and offers a striking contrast against the background of the branches and emerging foliage. Following the flowering season, the tree's leaves mature to a rich green, giving the tree a dense, leafy canopy. The shape of the leaves is elongated, with a serrated or toothed margin, and they come to a pointed tip. This creates a texture and fullness that contributes to the tree's overall aesthetics. As the seasons change, this tree's foliage transitions again, offering a stunning autumn display. The leaves may turn to warm shades of orange, red, and yellow, providing a burst of color before they fall. The cumulative effect of these colorful leaves against the autumn sky can be quite remarkable. Prunus 'Spire' also has a notable bark that adds to its visual interest, particularly in the winter when the leaves have fallen. The bark can be a source of subtle beauty, with a texture and pattern that provides visual interest even when the tree is dormant.

ToxicityTo humans
The Prunus 'Spire', commonly known as ornamental cherry, possesses components that can be toxic if ingested by humans. The seeds, leaves, and stems of the plant contain cyanogenic glycosides, which can release cyanide when chewed or digested. Ingesting parts of the plant, especially the seeds which have a higher concentration of the toxins, may lead to symptoms such as headache, dizziness, difficulty in breathing, and gastrointestinal distress. In severe cases, ingestion of large amounts can lead to cyanide poisoning, which is a potentially life-threatening condition that requires immediate medical attention.
To pets
The ornamental cherry or Prunus 'Spire' is toxic to pets, including dogs and cats. Similar to its effects on humans, the plant contains cyanogenic glycosides within the seeds, leaves, and stems that can convert to cyanide when ingested. Symptoms of poisoning in pets may include vomiting, diarrhea, abdominal pain, difficulty breathing, and lethargy. If a pet consumes a large amount, it could result in cyanide poisoning which poses a serious health risk and could be fatal if not treated promptly by a veterinarian.

WaterThe Spire Cherry tree, known commonly as the Prunus 'Spire', should be watered deeply but infrequently to encourage strong root development. Typically, watering once a week with about 1.5 to 2 gallons of water is sufficient; however, this can vary depending on your soil type and climate. During the growing season, increase the frequency to twice a week if there is insufficient rainfall. Ensure the water penetrates the soil to a depth of 12 to 18 inches. Reduce watering in the fall before the tree enters dormancy.
LightThe Spire Cherry tree thrives in full sun, meaning it should receive at least 6 to 8 hours of direct sunlight per day. The ideal spot for this tree is an area that provides unfiltered sunlight throughout the day, ensuring its growth and blossoming potential are maximized.
TemperatureThe Spire Cherry tree is hardy and can endure a range of temperature conditions, tolerating a minimum winter temperature of around -20 degrees Fahrenheit and a maximum summer temperature of about 100 degrees Fahrenheit. The ideal growth temperatures for this tree are between 65 and 75 degrees Fahrenheit.
PruningPrune the Spire Cherry tree to maintain its shape, remove any dead or diseased wood, and allow light into the center of the canopy. The best time to prune is in late winter to early spring before new growth starts. Ideally, light pruning should be done every year to maintain the ornamental appearance and health of the tree.
CleaningAs needed
SoilThe ideal soil mix for the Ornamental Cherry should be well-draining and fertile, with a pH ranging from 6.0 to 7.5. A blend of loam, peat, and sharp sand with added compost or well-rotted manure will support healthy growth.
RepottingOrnamental Cherry trees, being larger landscape plants, are not typically repotted. Instead, they are planted in a suitable location with adequate space to accommodate their growth.
Humidity & MistingOrnamental Cherry trees prefer outdoor conditions with natural humidity and do not require specific humidity levels to thrive; they adapt to the ambient humidity of their environment.
Suitable locationsIndoor

Life cyclePrunus 'Spire', commonly known as the 'Spire' Cherry, begins its life cycle when the seed germinates in late spring, after experiencing winter stratification. The seedling stage follows, where the plant establishes its root system and grows its first leaves. As it enters the juvenile stage, the 'Spire' Cherry develops strong branches and gains height rapidly, typically maturing within a few years. Once mature, it blossoms in spring with abundant white to pink flowers, attracting pollinators. After pollination, the flowers develop into small, non-edible fruits by summer end, which disperse seeds for the next generation. The tree continues to grow and can have a lifespan of several decades, during which time it will undergo periods of dormancy in winter with yearly cycles of flowering and fruiting.
PropogationPropogation time
Spring-Early Summer
One of the most popular methods for propagating the 'Spire' Cherry, which is a variety of ornamental cherry, is by semi-hardwood cuttings. This typically involves taking cuttings from the current year's growth in late summer, when the wood has matured to a semi-hardwood state. The cuttings should be about 4 to 6 inches (10 to 15 cm) long, with leaves removed from the lower half. These cuttings would then be dipped in rooting hormone to encourage root development and then planted in a mixture of potting soil and perlite or sand to provide adequate drainage. The cuttings need to be kept under high humidity and consistent moisture until roots have developed, which can take several weeks to a few months. To retain moisture and create a humid environment, a plastic bag or a propagator can be placed over the cuttings, and it should be placed in indirect light until rooted, after which it can be gradually acclimatized to more sunlight.
