Dalea candida is a species of flowering plant in the legume family known by the common name white prairie clover. It is native to North America, where it can be found throughout central Canada, the central United States, and northern Mexico. It can sometimes be found outside its range as an introduced species. It grows in many types of habitat, including several types of prairie, foothills, woods, forests, and disturbed areas. It is a perennial herb growing erect to a maximum height around 1 meter (3 ft 3 in), its taproot growing up to 5 or 6 feet (1.5 or 1.8 m) deep. The alternately arranged leaves are each composed of several narrow, gland-dotted, light green leaflets. The inflorescence is a dense cylindrical spike of flowers at the tip of each stem or stem branch. The spike is packed with the pointed green calyces of sepals, the lower ones bearing corollas of white petals and the higher ones blooming later. The fruit is a green oval legume pod containing one seed. A specimen of this species was collected by Meriwether Lewis in Nebraska in 1804.
White prairie clover has strong disease resistance and is generally not susceptible to illnesses. Still, it can be affected by pests and diseases present in its environment. Those infections are typically not serious. Regarding care, this plant needs a moderate amount of maintenance. It benefits from regular pruning to keep a neat appearance and healthy growth. Fertilizing can also encourage flowering. White prairie clover is appropriate for anyone with outdoor space, such as a garden or patio, and does not demand extensive care experience. It may need more attention when grown indoors.
How to keep Dalea Candida.
Light
White prairie clover needs plentiful, unobstructed sunlight to grow well. Native to areas with open skies, it performs best in those conditions. This requirement stays largely the same at different growth stages. Too little sun limits its development, while too much sun does not cause issues.
Water
White prairie clover thrives in environments with moderate moisture but can also withstand short periods of drought. For optimal growth, it's best to water it weekly. This plant prefers to be outdoors, where it can take advantage of natural rainfall and seasonal changes that boost its resilience.
Temperature
White prairie clover is indigenous to temperate regions, thriving in places where temperatures range from 32 to 90 °F (0 to 32 ℃). It can adapt to colder winters and hotter summers, adjusting its metabolic functions accordingly.
Fertilizer
The best time to fertilize White prairie clover is in early spring, as it comes out of dormancy and begins active growth. Fertilization supplies essential nutrients for healthy development. Although White prairie clover needs relatively little fertilizer, applying it annually can improve its survival and promote better, longer-lasting flowers.
Pruning
White prairie clover grows densely and produces white flowers. For best results, prune in early spring to remove any dead stems and later in the season to shape the plant. This encourages good air circulation, enhances the health of the blooms, and helps maintain the plant's vigor. Proper pruning supports seasonal growth and maximizes the floral display.

How should I water my White prairie clover for the best results?
When watering the White prairie clover, it is important to use filtered water at room temperature. Tap water may contain harmful particles, which is why filtered water is preferred. The plant prefers warm water as it is used to a warm environment, and cold water can be a shock to its system. Instead of overhead watering, it is best to water the soil directly with filtered room temperature water until the soil is completely soaked. This benefits the plant by moistening the roots and helping them spread through the soil to gather necessary nutrients.
Why should I add fertilizer to my White prairie clover?
The leaves of the White prairie clover are essential for its structure. Fertilization plays a vital role in maintaining the quality of these leaves. It ensures consistent color and a healthy texture. Additionally, fertilization supports the growth of new roots and maintains existing ones below the soil's surface. This not only keeps the plant healthy currently, but also improves its ability to absorb soil nutrients in the long run.
What kind of sunlight does White prairie clover require?
White prairie clover, like other perennials, requires at least six hours of direct sunlight each day to maintain its leaves, roots, and blooms. However, there are some exceptions, such as the Orange Daylily or Giant Coreopsis, which can survive with just three hours of direct sunlight daily. It's important to note that while these flowering plants can tolerate less sunlight, they won't flourish as well as they would in sunnier conditions.
What is the best temperature for White prairie clover?
The best temperature for White prairie clover depends on the time of year. Let's discuss the growing season and the dormancy season separately. During the growing season, which is when the plant has sprouted, the ideal temperature range is 65-80℉ (18-27℃). If it gets colder than 15℉ (-10℃), the plant will suffer and its leaves may brown and wilt. However, if it's just a short cold snap, the White prairie clover might survive with some assistance. On the other hand, during the warmer parts of the year, the plant should also be protected from very high temperatures. The top of its temperature range is 95-105℉ (35-40℃). Temperatures above that can harm the foliage and blooms, leading to wilting, drooping, and sunburn on the leaves. Recovering from this damage can be difficult for White prairie clover. Fortunately, there are quick and easy ways to combat this issue.
What do I need to do if I give too much or too little water to my White prairie clover plant?
Overwatering is a more common issue than underwatering for White prairie clover. When overwatered, the stems and leaves wilt and turn yellow. This can also lead to diseases like root rot, mold, and mildew which can be fatal for the plant. While underwatering is less common, it can still happen and is characterized by brittle, brown leaves. It's important to catch signs of overwatering early as some diseases may be irreversible if not addressed promptly. Reduce watering if signs of overwatering are noticed and check the soil's drainage. Replace poorly-draining soil with a loose, well-draining potting mix if necessary. If there are signs of underwatering, increase watering until the signs subside.
When should I fertilize my White prairie clover for the best results?
White prairie clover, a perennial plant, will begin sending out new growth in early spring when grown outdoors. This is your cue to start fertilizing for the year. One application of fertilizer in the spring is usually sufficient for the plant to thrive. However, if you want to maximize its growth, you can fertilize multiple times during the spring and early summer. In this case, you should feed the plant approximately once every month to a month and a half.
Can the sun harm White prairie clover? How can we safeguard White prairie clover from the damaging effects of sun and heat?
In warm climates, some Perennial Flowering Plants may struggle with excessive heat and suffer from sun damage. They can wilt, dry out, or even experience growth problems if they are consistently exposed to the intense afternoon sun. However, not all plants require protection from the light afternoon sun. For those that are harmed by intense afternoon exposure, it is recommended to provide them with some shade in warmer climates. Gardeners can achieve this by planting these plants in areas that do not receive direct heat during the afternoon, such as under trees or behind bushes.
The temperature that the White prairie clover seedlings need in their first year.
If this is the first year that you are growing white prairie clover outdoors, it may require some extra care during the coldest months. Frost can cause significant damage to young white prairie clover plants and even prevent them from growing back in the spring. To prevent this, it is important to keep the temperature above 40℉ (5℃) for these plants until they are fully established. This can be achieved by either bringing them indoors for a month or two or by using mulch or fabric covers to shield them from frost. During the first year or two, it is advisable to plant white prairie clover in a shaded area. Smaller and weaker plants have a harder time regulating their own temperature in hot weather. To avoid overheating, these plants should receive no more than five hours of direct sunlight per day, especially if the daytime temperature reaches above 80℉ (27℃). To control heat during summer, it is recommended to use shadecloth and ensure frequent watering or misting.
How frequently do I need to water my White prairie clover?
If your White prairie clover is in a pot, determining if it needs water is simple. Just stick your finger in the soil and if the top couple inches are dry, it's time to water. The same method can be used if you have your White prairie clover planted in the ground. Once again, if the top few inches of soil are dry, it's time to add water. Typically, watering once a week is sufficient during the spring and early fall. However, during especially hot weather, you may need to water twice a week or more. It's worth noting that mature, well-established White prairie clover can withstand drought quite well.
When is it not a good time to fertilize my White prairie clover?
During late fall and winter, your White prairie clover will go into a dormant phase and stop producing new growth. So, don't fertilize it during this time. When spring and summer arrive, you can fertilize multiple times, but start reducing the rate as summer gets closer because the growth rate of your White prairie clover will also slow down. Remember, it's never a good idea to fertilize your White prairie clover during very hot weather or when the soil is extremely dry. Doing so can stress the plant and cause it to die prematurely.
Should I keep White prairie clover out of the sun?
Certain perennial plants require ample sunlight to reach their maximum bloom. However, in warmer climates, some of these plants actually benefit from less sun. For instance, individuals residing in hotter regions might find it beneficial to shade their flowering perennials during the intense afternoon sun, especially during summer months. Although many perennial flowering plants prefer partial shade in the hottest climates, there are exceptions. Take the Giant Coreopsis, for example, as it is not bothered by excessive sun exposure. These plants can flourish even when placed in the full sun during scorching weather.
How do I keep White prairie clover safe from very hot or very cold temperatures?
To protect White prairie clover from cold temperatures below 15℉(-10℃), you have a few options. If you're growing the clover in a container, bring it inside until temperatures rise above the lower threshold. For ground-planted clover, use mulch or horticultural fabric to create a protective barrier against frost and cold wind. On the other hand, if temperatures exceed 80℉(27℃) in the shade, be cautious about exposing the clover to too much sunlight. Limit its exposure to six hours or less per day, preferably in the morning. Installing shade cloth or fine plastic mesh can help reduce direct sunlight during the hottest parts of the day. Additionally, using a misting system to release cooling mist around the plant's base can help lower ground temperatures.
