Euphorbia Hypericifolia Inneuphdia: Diamond Frost Euphorbia Plant Care

Diamond Frost Euphorbias are flowering succulent plants commonly cultivated as an annual and commonly used in landscaping and as indoor plants.

It blooms a profusion of small white and fragrant flowers from the spring through the fall.

Its tall upright stems are covered with thin, pale grayish-green to bright green leaves that are spaced far apart.

Diamond frost euphorbia plants are fairly hardy plants and are easy to care for once established in the garden or as a houseplant. In warmer regions, they can be grown as annuals.

Related to Poinsettia plants, they exude a milky sap when injured or cut, so be sure to wear gloves when handling them to avoid any skin irritation, especially if you have sensitive skin.

What is a Diamond Frost Euphorbia Plant?

Diamond Frost euphorbia (botanical name of Euphorbia hypericifolia ‘Inneuphdia’) are herbaceous flowering plants commonly used in landscaping and as indoor plants.

Their bright green leaves and small white flowers make them attractive bedding plants for garden beds or hanging baskets.

Origins

This plant is native to warm regions in South America and the southern United States, and is therefore adapted to be drought tolerant.

In these climates, Diamond Frost plants can be grown outdoors in full sun, though they can adapt to partial shade conditions as well.

Not adapted for cold climate zones, they should be protected from frost or moved indoors for the winter.

Diamond Frost is a Euphorbia hybrid that was introduced and trademarked by Proven Winners Nursery.

Growth Habit and Blooms

Growth-Habit-And-Blooms-Diamond-Frost-Euphorbia-Plant

Diamond Frost plants can grow to be moderately tall, at about 12-18 inches high, and can spread the same amount in width.

Their mounding growth habit makes them good candidates for hanging baskets or planting as border plants around a garden bed.

Thanks to their toxic sap, they are also rabbit and deer resistant.

Flowering times can vary from early spring to late summer. Their tiny white flowers, reminiscent of baby’s breath, make this a good substitute in floral arrangements or as a way to break up greenery in the garden.

The bold, gray-green foliage provides a lovely visual contrast against other colorful foliage or flowers.

In contrast to other flowering plants, once the flowers have been spent, the plant will drop them, requiring no additional deadheading to be done.

How to Care for Diamond Frost Euphorbia

While it takes a bit of maintenance to start, once established, a Diamond Frost plant is very low maintenance.

These plants thrive in USDA hardiness zones 10–11 and in temperatures between 60 and 85 degrees Fahrenheit.

Light

Light-For-Diamond-Frost-Euphorbia

Full sun to partial shade is the preferred amount of light for a Euphorbia diamond frost to thrive, although partial sun will suffice. Under lower light conditions, flowers may not bloom to their fullest.

If grown indoors, place your Diamond Frost in an area where your plant can get at least 4 to 6 hours of indirect sun or part shade for the best growth.

Climate

Euphorbia diamond frost is most suited for warm climates with dry conditions. Most of the United States will find growing this plant year-round outdoors to be a challenge, if not impossible.

When adding to the landscape, consider any frost that might occur during the winter that could damage your plant.

Watering

Watering-Diamond-Frost-Euphorbia

Water your Diamond Frost plant when the soil is dry, especially during warmer temperatures.

In general, Euphorbia plants are drought-tolerant plants that can dry out most of the way through the soil between waterings.

Provide supplemental water if outdoors, as the rain should be enough to sustain your Euphorbia diamond frost.

Always err on the side of under-watering drought-tolerant plants to avoid root damage due to rot.

For an indoor plant, provide enough water to soak the soil and flow out of the pot’s drainage hole, or enough to saturate the root system if planted in the ground.

Water when the soil has dried out 50–75% of the way from the top of the pot.

Soil

Soil-For-Diamond-Frost-Euphorbia

Euphorbia diamond frost needs well-drained soil. An excess of water can cause root damage and rot.

Repairing root damage can be a difficult process that is not always going to work, depending on the damage to the plant.

We highly suggest using soil that is designed for succulents or cacti. The one succulent potting mix that we always rely on is this succulent soil. We like it because our succulents seem to thrive in it.

Fertilizer

Fertilizer for Diamond Frost plants is required upon first planting in the ground, though as the plant gets established, the need for feeding decreases.

Plants in containers can be fed on a regular basis using a balanced liquid fertilizer to help maintain healthy growth.

Pests

Pests-of-Diamond-Frost-Euphorbia

Euphorbia diamond frost is not particularly susceptible to many pests, especially if it is being maintained and cared for properly. This does not mean one shouldn’t inspect these plants upon purchase.

Look out for common pests such as spider mites and mealybugs. Spider mites create webs around new growth and flower buds, and mealybugs appear as white and cottony protrusions that usually congregate on your plant’s midveins and stems.

These can be treated simply with a neem oil spray or by controlling small outbreaks using rubbing alcohol and cotton swabs to dab at creatures if they’re large enough, like mealybugs.

Removal of entirely affected leaves or branches is also an effective method of controlling pest infestations.

Diseases

Diseases are not typical in Euphorbia diamond frost and would arise due to poor conditions.

Humid and damp conditions can make mold or mildew an issue, as well as if there is not good airflow to the base of the plant.

Caring for Diamond Frost appropriately is the best approach to prevent any plant disease.

Repotting

Repotting-Diamond-Frost-Euphorbia

Repotting should be done when your Diamond Frost plant begins to push roots out of its drainage holes or otherwise starts to escape the pot.

This can vary depending on container size and how vigorous the growth is.

Outdoor plants shouldn’t have to be concerned with relocation unless the euphorbia diamond frost was not planted with sufficient room to grow.

Repotting can cause stress to a plant, so it is best to do so only when necessary and during the growing season, if possible.

If you’re looking for a new pot, consider a pot that waters itself. This self-watering pot is what we use for our indoor plants. We never have to worry about overwatering.

Propagation

Propagation can be done through the stems by allowing them to root in water or soil.  

Since this plant is a patented plant, only stem cuttings for personal propagation are legal.

Using a clean, sharp knife, cut 1/4 inch below a node on a healthy, robust branch.

As an aside, if you’re looking for a pair of shears, we highly suggest these super-sharp pruning shears. So much easier to use than a knife. They are not too expensive and they seem to never dull.

Wash off the sap that has exuded in cold water before setting it aside in a shaded area to allow the wound to scab over for a day.

After the wound has healed, you can place the cutting in a glass of clean water to propagate it in water or plant it in about 2 inches of deep potting soil made for seedlings.

Provide a warm spot out of direct light for the cutting, whether it is in soil or water, to promote growth.

Pruning

You should cut back Diamond Frost plants in the late spring to encourage new growth during the growing season.

Pruning should be done with a sharp knife or pruning shears; ensure that they are clean.

Avoid trimming the upper portions of your plants; excessive trimming can cause stunted growth.

FAQ

Does Diamond Frost Like Sun?

Diamond Frost plants like the sun. Full sun to partial shade is the ideal amount of light for it to thrive, although even partial sun can suffice in some cases. Flowers may not bloom to their full potential when exposed to low light conditions. If you’re growing your Diamond Frost indoors, make sure it has at least 4 to 6 hours of indirect sunlight or part shade per day for the best growth possible.

Is Diamond Frost Euphorbia a Perennial?

In most regions, the Diamond Frost Euphorbia plant is a perennial, specifically in USDA Hardiness zones 10–12. However, in colder climates, this root-hardy plant should be planted as an annual.

Is Euphorbia Diamond Frost Hardy?

Euphorbia diamond frost is not frost hardy. In cold climates or USDA hardiness zones 9 and below, Diamond Frost plants should be planted as annuals. Because it only blooms for a short time, this half-hardy annual should be treated like a seasonal bedding plant. On the other hand, in USDA hardiness zones 10 and higher, you can plant them as perennials.

Can You Propagate Diamond Frost Euphorbia?

If you plan to sell your propagated Diamond Frost plants, you cannot legally do so. It is a patented plant by Proven Winners and can only be propagated by licensed producers. With that said, you can propagate Diamond Frost cuttings for your personal use. Remember, these are Euphorbia plants, so when cutting them, wear gloves and eye protection because the milky sap they produce is toxic.

How Do You Winterize Diamond Frost Plants?

You can either treat Euphorbia diamond frost plants as an annual if you plant them in colder climate environments or replant them in the spring. Alternatively, it’s best to move them indoors during the winter or when the weather starts to frost up.

Other Euphorbia Plants

Euphorbia diamond frost is a hardy and easy-to-care-for plant once it is established in an appropriate climate.

The small white flowers pair well in bouquets and in the garden alike, complementing other plants around them while still standing out on their own.

However, if you have other Euphorbia plants in mind, there are numerous others to choose from. Below are just a sample of some Euphorbia plants you can grow indoors or outdoors.

Euphorbia Lambii: This plant is widely used as a landscape plant outside. Although it is known as the Tree Euphorbia or Truffula Tree, it is essentially a strange-looking Euphorbia plant with a top-heavy appearance. It will certainly enhance the visual appeal of your front yard.

Euphorbia Obesa: These low-maintenance plants, often called “baseball plants,” “basketball plants,” and “living baseballs,” thrive with little water and moderate light. Euphorbia obesa is a good choice if you are looking for a low-maintenance, drought-resistant plant that will add a unique touch to your landscaping.

Euphorbia Flanaganii: Often known as Medusa’s Head plant, is a rare, evergreen, spineless succulent plant with long, wavy stems that mimic the mythical creature’s serpentine hair. In contrast to the majority of succulents, it has horizontally spreading stems or branches that resemble snakes. Each has a Fibonacci spiral-like helix at its center, and no two are alike.
