dahlia 'Trooper Dan'


Dahlia 'Trooper Dan' is a striking ornamental plant known for its richly hued, vibrant flowers. At the heart of its appearance are the blooms, which showcase a blend of deep reds to burgundy petals that are typically broad and slightly curved toward the tips, often giving them a full and lush look. The flowers possess a semi-cactus form, where the petals tend to roll up along their lengths, giving them a somewhat tubular shape that adds a unique spiky texture to the flower head. The petals are arranged in a radial pattern around a central disc, which is usually not visible due to the density of the surrounding petals. This results in a rounded overall form of the flower that is quite plush and inviting. These luxurious blooms stand out against the dark green foliage that sits beneath them. The leaves are usually pinnate with pointed leaflets, imparting an elegant backdrop that accentuates the flowers' rich colors. Dahlia 'Trooper Dan' presents a robust presence in the garden. The stems that hold the flowers are sturdy and capable of supporting the heavy heads, which helps maintain the plant's aesthetic appeal throughout its blooming season. It is not uncommon for these dahlias to serve as eye-catching focal points in a garden setting or to be used as stunning cut flowers for indoor arrangements due to their impressive and ornate blossoms. Overall, the appearance of Dahlia 'Trooper Dan' is one of drama and beauty, marking it as a favorite among both gardeners and floral enthusiasts.

As needed
  • water dropWater

    Dahlias, including 'Trooper Dan', require consistent moisture for best growth, particularly in dry conditions. They should be watered deeply at least two to three times a week, allowing the soil to dry out slightly between waterings. An inch or two of water per week is a good general rule. During particularly hot or dry spells, water usage may need to increase, and mulching can help retain soil moisture. To avoid disease, water the plants at the ground level rather than overhead to keep the foliage dry.

  • sunLight

    For optimal growth, Dahlias such as 'Trooper Dan' should be planted in a location that receives full sunlight for at least six to eight hours a day. They thrive when getting direct sunlight and may become leggy or produce fewer blooms if light is insufficient. Selecting a south-facing garden spot free from the shade of buildings or trees will provide the ideal light conditions.

  • thermometerTemperature

    Dahlias like 'Trooper Dan' prefer temperatures between 60 to 70 degrees Fahrenheit for ideal growth. They can survive in temperatures as low as the upper 50s overnight but require protection or removal if a frost is expected, as they are sensitive to freezing temperatures below 32 degrees Fahrenheit. Dahlias perform best in warm, consistent temperatures and often struggle or go dormant when it gets too hot, above 90 degrees Fahrenheit.

  • scissorsPruning

    Pruning Dahlias like 'Trooper Dan' encourages better air circulation, reduces disease risk and promotes more prolific blooming. Pinch or cut back the main shoot to promote bushiness when the plant is about a foot tall, and remove spent flower heads (deadheading) regularly to foster more blooms. The best time for major pruning is early in the season and when deadheading throughout the bloom period.

    As needed

  • bambooSoil

    Dahlias prefer a well-draining soil mix with a pH of around 6.5 to 7.0. A good mix for Dahlia 'Trooper Dan' would be two parts garden soil, one part peat moss or coconut coir, and one part perlite or vermiculite to aid in drainage. Ensure that organic matter like aged compost is also incorporated to provide the necessary nutrients.

  • plantRepotting

    Dahlias, including 'Trooper Dan', generally don’t need to be repotted if they are growing in the ground. However, for container-grown dahlias, repotting should be done annually, usually in the spring when the new growth starts to appear. This prevents them from becoming root-bound and allows replenishment of the soil's nutrients.

  • water dropsHumidity & Misting

    Dahlias do not require high humidity and are tolerant of the typical outdoor humidity levels found in their growing zones. They grow best when the humidity is not excessively high, as too much humidity can promote fungal diseases.

  • circleLife cycle

    The life of Dahlia 'Trooper Dan' (S-c) begins with the germination of tuberous roots in spring when soil temperatures rise above 60°F. As the plant emerges, it enters the vegetative growth stage, developing a sturdy stem and symmetrical leaves. During the summer growing season, it transitions to the flowering stage, blossoming into vibrant, spiky flowers with colors ranging from red, orange, and yellow to purple and white. Once pollinated, the flowers can produce seeds, although dahlias are more commonly reproduced through division of tubers. As fall approaches, the plant's growth slows and it enters a period of dormancy after the first frost, when the top growth dies back and the tubers can be stored for the winter. Come the next spring, the cycle repeats as the stored tubers are replanted, initiating a new season of growth.

      Spring-Early Summer

    • The most popular method of propagating Dahlia 'Trooper Dan', a type of garden dahlia, is through division of its tuberous roots. This is typically done in early spring just before or as new growth begins to emerge. Gardeners carefully dig up the clumps of dahlia tubers and wash off any excess soil to get a clear view of the tubers and the eyes from which new shoots grow. Using a sharp, clean knife or shears, they cut the clump into sections, making sure that each division has at least one eye and a portion of the original tuber attached. The cut surfaces are often treated with a fungicide to prevent rot and then allowed to dry for a day before planting. The divisions are then planted about 6 to 8 inches (15 to 20 centimeters) deep in well-drained, fertile soil with the eye facing upward.
