Drosera brevifolia
Dwarf Sundew · Shortleaf sundew
Description
Source: leafsnapDrosera brevifolia (the dwarf, small or red sundew), is a carnivorous plant of the family Droseraceae and is the smallest sundew species native to the United States. This species differs considerably from the pink sundew, Drosera capillaris, by its wedge-shaped leaves, and distinctly deeper red to reddish purple color, noticeable when side by side with D. capillaris. D. brevifolia is usually a small plant, typically no more than 3 centimeters across, though some are known to grow up to 5 cm in the open sandy woods in west Louisiana, with flower spikes up to 15 cm. It is often found growing in areas drier than what most carnivorous plants prefer, where it often will set seed and die when the dry hot summer arrives and return as seedlings in late fall or winter. The range of D. brevifolia is from east Texas to Florida and north to Virginia. Flowers can be large compared to the rosette and can be pink or white and come in the spring. Most of the plants die off in the dry summer after setting seed. New seedlings return in the fall with cooler, damper weather. According to the USDA, it is endangered in the State of Kentucky and threatened in the State of Tennessee.
Care Guide
💧 Water 2-3 times a month
The dwarf sundew thrives in humid environments, making it well-suited to moisture-rich tropical habitats. It requires consistent moisture, which is best maintained by watering it twice a week. Gardeners should adjust this watering schedule based on seasonal rainfall patterns to ensure optimal growth, especially when the plant is grown outdoors.
How should you water your Dwarf sundew plant?
To keep your Dwarf sundew properly hydrated, here are some tips. First, place it in a pot with good drainage holes. Then, place the pot in a plastic dish or tray and fill it with about a third to half an inch of water. This will allow the water to naturally reach the roots as the soil dries out. Make sure the dish never completely dries out, and adjust the amount of water based on how quickly the plant absorbs it. Terra cotta pots are not suitable for growing the Dwarf sundew, unless you use a second, larger pot to hold the water. The terra cotta pot will allow water to seep through and filter out dissolved solids. Only add water to the outer pot. The mineral content of the water you use is crucial for watering your Dwarf sundew. If possible, collect rainwater as it is the safest option. Alternatively, distilled water and water from a reverse osmosis system are good alternatives. Purified water can also be used, but keep in mind that it may contain some minerals that the Dwarf sundew can tolerate. Tap water with less than 50 parts per million of total dissolved solids is safe to use. You can purchase a meter to measure this at a low cost. It's recommended to fill your watering device 24 hours in advance to allow chlorine to dissipate from the water.
What do I do if I give Dwarf sundew too much or too little water?
Dwarf sundew plants that are overwatered may show brown spots on the undersides of their leaves, have white mold in the soil, and look wilted. The wilted appearance is a result of the plant's inability to draw water into its stems. Overwatering can lead to root rot, which can be identified by a bad smell and a rotted root system. In such cases, it is advisable to gently remove the plant from its soil, rinse it using distilled water, trim away the affected roots and leaves, rinse it once again, and then replant it in fresh soil. On the other hand, if a Dwarf sundew plant is underwatered, its leaves may become brittle. In this situation, it is recommended to trim away any affected leaves, ensure that the soil is moist, and mist the leaves. Although an underwatered plant should gradually recover once it receives sufficient watering, it's important to note that there may be some short-term damage to the roots, resulting in the drying out of yellow leaves.
How often should I give water to my Dwarf sundew?
The tray method is commonly used to water insectivorous plants, such as the Dwarf sundew. To use this method, pot the plant in a container with several drainage holes and place it in a tray or dish filled about one-third with water. As the soil dries, the plant will naturally draw water up from the tray. Make sure to promptly add water when the level drops, and avoid allowing the dish to completely dry out. This will help you determine how often the plants need to be watered. The Dwarf sundew is native to humid environments, so it's important to find the right balance between watering and avoiding root rot. During the active seasons of spring to autumn, avoid letting the soil dry out completely. In these seasons, water the Dwarf sundew 2-3 times per week, and increase watering frequency in the summer to keep the soil moist. However, during the dormant winter and early spring months, you should water the plant less. Allow some of the soil to dry out and let the water level in the tray dry out for a few days before adding more water. If you live in an area with naturally dry air, you may need to mist the Dwarf sundew in addition to regular watering to recreate its natural humid growing conditions. It's recommended to do this in the morning. Proper water spraying is particularly important in dry environments.
How much water does my Dwarf sundew need? --> How much water does my little sundew plant need?
Dwarf sundew is a carnivorous plant that thrives in humid environments and is often kept as a houseplant. To successfully care for this plant, you will need to recreate its native growing conditions, which involve maintaining high humidity levels. If you live in a naturally humid area, you can grow them outdoors in a bog garden. Otherwise, most people choose to grow them as houseplants. To minimize the frequency of waterings, it's recommended to use a pot that retains moisture, such as plastic or a self-watering pot. The tray method is the most effective way to replenish water for these insect-eating plants. Make sure the water level in the tray pots covers the small hole at the bottom, and refill it in time to prevent the trays from drying out. This will provide the necessary amount of water for your Dwarf sundew to thrive.
Do I need to water Dwarf sundew differently when I plant it inside instead of outside?
When growing dwarf sundews indoors, they need less water due to receiving less sunlight. The more light they receive, the more water they will need to grow properly. It's important to provide sufficient light and water to keep them healthy. Additionally, it is crucial to maintain a humid environment for indoor plants. One way to achieve this is by growing them in a terrarium or incorporating them into a plant display in an aquarium. This will help trap the necessary humid air. However, it is important to ensure adequate air circulation.
☀️ Light Full sun
The dwarf sundew does best in lower light conditions. The predominantly shaded environment of its origin has shaped its evolving preference for these conditions. At every stage of growth, minimal light exposure is preferable. Excessive light can impair its growth, while insufficient light does not significantly affect it.
What are the sunlight requirements for Dwarf sundew?
Dwarf sundew thrives under conditions with less sunlight, reflecting its origin's environment which is predominantly shaded. The plant demonstrates a marked preference for minimal light exposure throughout all its growth stages, with overexposure to light negatively impacting its growth, while insufficient light has less significant effects. Specifically, it requires less than 3 hours of sunlight, fitting into the 'full shade' category. Observing how sunlight moves through your garden and choosing spots that provide a balance of light and shade is crucial for the happiness of your plants.
How can artificial lighting be used for Dwarf sundew?
When natural sunlight is insufficient, particularly during winter or in less sunny spaces, artificial lighting can be a vital solution for dwarf sundew growth. It's recommended to use artificial lighting to promote faster, healthier plant growth, with LED lights being a popular choice because they can provide the specific wavelengths of light plants need. For full sun plants, 30-50W/sq ft of artificial light is needed, partial sun plants require 20-30W/sq ft, and full shade plants need 10-20W/sq ft. The artificial light source should be placed 12-36 inches above the plant, mimicking natural sunlight, and kept on for 8-12 hours per day.
What are the symptoms of light deficiency in Dwarf sundew?
Symptoms of light deficiency in Dwarf sundew include smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, and lighter-colored new leaves, indicating a lack of chlorophyll and essential nutrients. Conditions caused by excessive sunlight include chlorosis, sunscald, leaf curling, wilting, and leaf scorching. Each of these conditions has a distinct impact on the plant's health, affecting its color, structure, and overall growth.
What solutions are available for light-related issues in Dwarf sundew?
Solutions for light-related issues in Dwarf sundew involve strategic relocation and the use of artificial lighting. For indoor plants, moving them to a spot where they can receive ample filtered light, including brief periods of direct morning sunlight, is recommended. Placing plants 1-2 meters away from a window or using a desk or ceiling lamp for at least 8 hours daily can help. Outdoor plants should be gradually moved to sunnier locations each week to avoid sunburn. Minimizing obstructions like pruning blocking trees or transplanting smaller plants to sunnier locations with good drainage also assists in increasing light exposure. Parts of the plant that were previously affected by insufficient light may not recover, but new growth post-increased light exposure will be healthy.
