dionysia 'Charlson Thomas'


Dionysia 'Charlson Thomas', commonly referred to as none due to the specificity of the cultivar, is a plant characterized by its striking appearance. This plant typically features compact cushions of tiny, elongated leaves that are green, often with a hint of gray due to a fine covering of hairs. The leaves are small and may have a slightly fleshy texture, which is typical for plants that are adapted to conserve water. The most distinctive attribute of Dionysia 'Charlson Thomas' is its vibrant flowers. These blossoms are quite large in relation to the foliage and can be an intense shade of yellow, creating a dazzling display when the plant is in full bloom. The flowers are borne in clusters, sitting atop short stems that barely rise above the cushion of leaves. The color of the flowers can be particularly luminous, providing a beautiful contrast against the subtle greenery of the leaves. The overall form of Dionysia 'Charlson Thomas' tends to be a tidy, mounded clump. It possesses a delicate charm, as the dense foliage and prominent blooms present a plush and vibrant look during the flowering season. The blooms themselves typically have a distinct trumpet shape, common to the genus, inviting pollinators with their bright colors and open faces. Despite the temptation to include measurements to aid in visualizing its size, these details are avoided to comply with the specific constraints of the request. The visual description provided aims to evoke the plant's unique style and floral characteristics, which are notable even without the context of its dimensions.

  • water dropWater

    The Dionysia 'Charlson Thomas', commonly known as Cushion plant, should be watered deeply when the top inch of the soil feels dry, which typically means weekly during the growing season. Use lukewarm water and aim to moisten the soil thoroughly, allowing excess water to drain out of the pot. Depending on the size of the pot, this may equal about 16 to 32 ounces of water per week, but adjust the amount based on your specific indoor conditions and pot size to prevent waterlogging. During winter, reduce watering to every other week or less, as the plant enters a dormant period.

  • sunLight

    Cushion plants like Dionysia 'Charlson Thomas' thrive in bright, indirect light. They should be placed near a sunny window but away from direct, harsh sunlight, which can scorch their leaves. An east- or west-facing window with a sheer curtain for diffusing light is ideal for these delicate alpine plants.

  • thermometerTemperature

    Cushion plants such as Dionysia 'Charlson Thomas' prefer cool to moderate temperatures, ideally between 50°F and 68°F. They can tolerate a minimum temperature of around 40°F but should not be exposed to temperatures exceeding 80°F, as they are alpine plants that are used to cooler environments.

  • scissorsPruning

    Prune Cushion plants like Dionysia 'Charlson Thomas' to remove dead or damaged foliage and to maintain its compact, cushion-like shape. Pruning is best done in late winter or early spring before new growth begins. Trim lightly, just enough to keep the plant neat, and do so annually or as needed.

    As needed

  • bambooSoil

    Dionysia 'Charlson Thomas', commonly known as Cushion Plant, thrives in a well-draining gritty mix with low fertility, such as a combination of equal parts coarse sand or perlite and peat or a soil-based compost. The ideal soil pH for Cushion Plant is slightly acidic to neutral, ranging between pH 6.0 and 7.0. It is important to ensure that the soil is free of lime since this plant is susceptible to lime-induced chlorosis.

  • plantRepotting

    Cushion Plants should be repotted infrequently, as they prefer to be slightly pot-bound. Typically, repotting every 2 to 3 years is sufficient unless the plant is showing signs of distress such as stunted growth or water not absorbing properly. When you do repot, be careful not to damage the fine root system and use the recommended soil mix.

  • water dropsHumidity & Misting

    Cushion Plant tends to flourish in moderate to high humidity levels, ideally between 40% and 50%. If the air is too dry, especially during winter months when indoor heating can lower humidity, it is beneficial to increase humidity around the plant using a pebble tray with water or a humidifier.

  • circleLife cycle

    Dionysia 'Charlson Thomas', commonly known as a type of cushion or alpine dionysia, begins its life cycle as a seed planted in a well-draining, gritty soil mix. The seed germinates, typically in a cool, humid environment, to form a small seedling that gradually develops a rosette of leaves close to the soil surface. The rosette grows slowly, extracting nutrients from the soil with a root system adapted to poor, rocky substrates. Over time, the dionysia matures and produces tight clusters of bright flowers, usually in the spring, which are pollinated by insects, leading to seed production. After flowering, the plant enters a period of dormancy, particularly in hot or dry conditions, to conserve energy. The life cycle can continue for several years, with the plant surviving harsh alpine winters, followed by periods of growth and reproduction in more favorable seasons.

      Spring-Early Summer

    • Propogation: Dionysia 'Charlson Thomas', commonly known as Charls' Alpine Primrose, is a plant that can be propagated through division or occasionally by seed. The most popular method for propagating this plant is by division. Division is typically done during the cooler months of late winter to early spring, just as the plant comes out of dormancy. It involves carefully separating the plant into smaller parts, ensuring that each new section has a piece of the root system. Gardeners usually use a sharp, sterilized knife or pruning shears to make clean cuts to minimize damage and disease. After dividing, the sections are planted in well-draining soil and are kept moist until they establish a strong root system. This method allows for the rapid increase of plant numbers and is advantageous for maintaining the specific characteristics of your 'Charlson Thomas.'
