A member of the Euphorbiaceae family, which has members in a variety of startling sizes and shapes, Euphorbia is a very vast genus with around 2,000 species. They could be shrubs, trees, annuals, perennials, evergreens, or deciduous. The majority, which are native to temperate regions around the world, including the Mediterranean climate in Sonoma County, originated in Africa, Madagascar, and the Americas.
Poinsettia, a popular Christmas plant, is an example of Euphorbia pulcherrima. It stands out from the majority of its related species—often referred to as spurges—by having striking, vivid crimson bracts. Nearly all are perennials that require just moderate maintenance and are either evergreen or die back to the ground in the winter before regrowing in the spring. Their leafy stems have a variety of colours, sizes, and textures of leaves. The genus comprises a wide variety of forms, including, among others, mounds, upright stem sets, and low ground crawlers. Early spring through early summer is when euphorbias typically flower, and they then continue to produce lovely foliage all through the growing season or even all year long. Many are resistant to deer and gophers as well as drought.
The blooms on euphorbia are one of its most peculiar features. What is commonly referred to as a flower is actually a cyathium, which is made up of fused bracts that enclose a tiny true flower in a cup. On the ends of the leafy stems, groups of bracts that resemble leaves sprout. These bracts are typically vividly coloured, with many species having chartreuse bracts that reflect light and create an amazing display. The elegant leafy stems come in a variety of colours, including blue, blue-green, reddish-green, reddish-orange, and green with purple undertones.
Depending on the species, euphorbias have different planting needs. Many plants need direct sunlight, but others may survive in partial shade, and a few even thrive in complete shadow. The majority of species that grow well in Sonoma County enjoy heat and can withstand some frost. They can tolerate drought, but some require regular water, and almost all don’t like having wet feet.
Euphorbias have some shortcomings despite its numerous positive traits. Each plant has a milky white sap in its stem that stings when touched, can be poisonous if consumed, and is extremely painful if it gets in the eyes. It’s crucial to clip them carefully and clean them right after after pruning. Long sleeves and gloves both protect the hands and arms. The good news is that the gophers and deer stay away because of the unpleasant sap. Self-sowing and underground stem spread can both be a pain, but for the most part, undesirable plants are simple to remove.
robbiae euporbia amygdaloides This species, sometimes known as Mrs. Robb’s bonnet, can endure more shade than most euphorbias and is quite short (up to 1 foot tall). It can be a helpful variety where there is no supplementary summer irrigation, but only if it is carefully contained on all sides; otherwise, it can become an unwelcome and invasive pest. Individual stems grow quickly via rhizomes.
Characia euphorbia This plant grows to a height of about 4 feet in a dome-shaped canopy, with erect, evergreen stems densely covered in narrow, blue-green leaves. It produces magnificent, spherical clusters of vibrant chartreuse/lime green flower heads that endure for several weeks and bloom in late winter to early spring. To stop unwanted self-seeding and make space for newly sprouting shoots, stems should be pruned down to the base as seeds form. The variety of this plant that is most frequently grown is E. c. wulfenii. It enjoys direct sunlight and uses little water.
griffithii Euphorbia In comparison to the other species listed, this Himalayan native has a highly distinctive appearance. It spreads slowly by creeping roots and matures as an upright stem up to 3 feet tall. Early summer brings forth the fiery orange-red bracts of “Fireglow,” which produce a sea of colour and interest in areas with sun or filtered light and moderate moisture. To stop the spread and maintain control, cut it down to the ground in the winter and divide it every three to four years, if not more frequently. Some gardeners favour the related cultivar “Fern Cottage,” which is reputed to be less invasive.
Martini’s euphorbia This perennial, which is a cross between E. characias and E. amygdaloides, grows to a height of 2-3 feet and has dark green leaves with a hint of purple. In late winter to early spring, dense clusters of green blooms with dark centres appear at the tips of the branches. It does not reseed as frequently as other species, prefers full sun to part shade, and can withstand drought.
Myrsinites of Euphorbia This lovely evergreen plant, also known as myrtle spurge and donkey-tail spurge, has stems that extend outward from the crown and trail on the ground like an octopus. Early in the spring, the short, hefty blue-green leaves that cover the stems and end in clusters of chartreuse bracts lend a striking attraction to the environment. Cut entire stems back to the base as opposed to deadheading individual flowers, being careful not to remove slowly forming new stems. All year long, there will be new growth.
What plant has the most deer resistance?
- White-tailed deer damage to nurseries has been researched by researchers from the University of Rhode Island. They found that deer had a fondness for hostas, daylilies, and English ivy in particular.
A few study participants made the interesting observation that deer appear to choose fertilised plants over those that haven’t.
Which Plants Deer Don’t Want to Eat
It should come as no surprise that deer tend to avoid harmful plants. Deer steer clear of common flowers with toxicity like daffodils, foxgloves, and poppies.
- Deer also have a propensity to avoid plants with powerful odours. Flowers like peonies and bearded irises, as well as herbs like sages, decorative salvias, and lavender, are simply “stinky to deer.
- Would you like to consume anything sharp? Deer don’t either (unless they’re in a pinch). They avoid eating plants like lamb’s ear on their favoured menu.
Deer-Resistant Plants for Shade
- Bleeding hearts are one of our favourite perennials that can withstand deer (Lamprocapnos spectabilis, aka Dicentra spectabilis).
- Astilbe are plants that thrive in shade and are resistant to deer. Bridal Veil, Visions, and Fanal asters combine well.
Deer-Resistant Plants for Sun
- The Coreopsis verticillata ‘Zagreb’ variety has a long blooming season from May through September and attracts butterflies but not deer.
- The perennial Liatris spicata ‘Kobold’ or Blazing Star is another sun-loving plant that isn’t a favourite among the deer.
- One of our favourite native plants, Echinacea purpurea, attracts pollinators.
- Salvia x sylvestris, sometimes known as wood sage, is another sun-lover.
- Last but not least, a popular type of Shasta Daisy that deer do not prefer is Leucanthemum x superbum “Becky.”
List of Top Deer-Resistant Plants, Flowers, and Shrubs
Deer-resistant plants have been identified through research as those that are less likely to be consumed by deer. The list is below. Here is a list of common plants that deer rarely or never seriously harm. Remember that there are no plants that are entirely resistant to deer; this is the first rule of deer proofing.
Do deer consume hybrid euphorbias?
With its variegated foliage and vibrant flowers, this heat- and drought-tolerant perennial will give colour to sunny gardens and patio pots. Late April sees the blooming of its clusters of green, lime, and cream variegated blooms. Its multicoloured foliage is equally stunning. Its gray-green leaves have a golden edge, and in the fall, they change to colours of red, pink, and orange. This plant is a vibrant patio plant and provides months of flare to the garden. One of the final perennials to enter dormancy in the fall is this one. Deer and rabbit tend to stay away from it. grows most well in full sun to some shade.
What kinds of vines do deer avoid eating?
Carolina jessamine (Gelsemium sempervirens), trumpet creeper (Campsis radicans), crossvine (Bignonia capreolata), coral honeysuckle (Lonicera sempervirens), swamp leatherflower (Clematis crispa), and celastrus scandens (American bittersweet).
Which plants poison deer?
Deer can get sick from certain plants that are harmful to them. Bee plants, blue cardinal flowers, comfrey, some varieties of datura, dusty miller, nicotiana, different kinds of poppies, prairie flax, Texas bluebonnet, and tulips are examples of annuals. Deer are poisoned by century plants, foxglove, larkspur, lupine, narcissus, and daffodils. Blue larkspur, numerous datura species, joe-pye weed, Lindheimer’s senna, night-blooming jasmine, different types of red-hot poker, two-leaved senna, windflower, and woolly paperflower are examples of perennials.
Do coffee grounds deter opossums?
It’s upsetting to discover when you get up in the morning that all the time and effort you put into your garden has suddenly turned into a mess, with deer to blame.
Deer have keen senses of smell that they employ to locate readily available food sources. The bitter scent of used coffee grounds may warn deer that people are close and keep them away from your property even if there is no scientific proof that they will scare off deer.
Deer, despite their harmless appearance, frequently enter your property at night to either consume your plants or damage them by rubbing their antlers on your trees. In essence, can deer really be stopped in their tracks by coffee grounds?
Are hydrangea plants eaten by deer?
Are hydrangeas immune to deer? The quick response is no. Deer enjoy nibbling on the delicate tips, flowers, and leaves of hydrangeas. However, there are methods that hydrangea enthusiasts like me can employ to lessen deer damage. Plant the toughest hydrangea varieties first. Next, put up a fence to prevent deer from getting near your plants. To deter grazing, spritz deer repellant. To discover more about cultivating hydrangeas in a deer-populated area, continue reading.
Do bunnies consume euphorbia?
The best value is provided by Euphorbia milli, which has spiky stems and branches as well as a sap that is poisonous to rabbits and other animals.
Euphorbia: a resilient annual?
The genus Euphorbia contains a wide variety of species, including enormous spiky shrubs, the well-known holiday poinsettia (which is a perennial tree in its natural habitat), and prostrate annual weeds. These Euphorbiaceae spurge family members are distinguished by their succulent foliage and milky white latex sap. A new decorative Euphorbia with airy foliage and an abundance of tiny white blooms resembling baby’s breath was introduced in 2005 by Proven Winners.
The cultivar “Inneuphdia” (or occasionally spelled “Inneuphe”) is frequently offered under the trade name “Diamond Frost.” It is typically labelled as E. hypericifolia, E. graminea, or a hybrid with one of those species (or Chamaesyce hypericifolia after a recent reclassification).
Most locales grow this delicate perennial as an annual (hardy in zones 10–12 and root hardy in colder climates with protection). Plants have a mounding growth habit and reach heights of 12–20 inches. Widely spaced, slender, gray-green to bright green leaves are seen on the erect stalks.
From spring till frost, an abundance of tiny, snow-white “flowers” are generated at the top of the canopy.
Actually, what we refer to as flowers are bracts. Cooler temperature causes flowering to decrease, however Diamond Frost never stops blossoming because it is sterile and does not generate seeds. The blossoms can be used as filler in floral arrangements; to stop excessive sap loss, seal the cut ends in boiling water or a flame for a short period of time.
In containers, annual or mixed beds, front borders or cottage gardens as an accent plant or in masses, or as a walkway edger, Diamond Frost is a superb low maintenance addition. With other flowering plants of practically any type or colour, its little white blossoms go well. It makes a superb filler plant in mixed plantings due to the finely textured leaf, which contrasts well with plants with bigger leaves, and the billowing habit. The small, many blossoms have a baby’s breath-like impression.
They won’t harm perennials or roses when planted near them because of their shallow, non-competitive root system. It will overflow the edges of pots or hanging baskets and fill spaces between taller or trailing plants. If given enough light, it can also be grown as a houseplant that blooms all year round.
Grow this bedding plant in any kind of well-drained soil from full sun to partial shade. It is a hardy plant that will still look excellent even after some neglect or abuse. It is heat- and drought-tolerant, so little watering is needed (except those in containers),
very susceptible to overwatering, in fact. Although plants can be pruned at any time to encourage branching for a fuller appearance, form, or to keep their size under control, deadheading is not essential because faded blooms naturally fall off the plant, keeping it looking clean. When working with the plants, wear gloves because the sap might irritate delicate skin. Deer and bunnies do not prefer it because of the sap’s white, milky colour.
Since they are delicate perennials, they can be kept indoors throughout the winter if brought in before the first frost and kept in a sunny location. They could be used as an accent plant for poinsettias during the holidays if kept in good condition.
After the risk of frost has passed, the plants should be placed outside after receiving a spring pruning. It can be produced from seed but can only be propagated by herbaceous stem cuttings (propagating them to sell them is prohibited unless you have a permission).
The majority of individuals buy tiny plants in the spring. Never plant outdoors until all threat of frost has passed.
In addition to Diamond Frost, there are several more types with green leaves and white blossoms that are difficult for the typical person to distinguish from one another (BreathlessTM White, “Hip Hop,” “White Manaus,” etc.). Diamond Frost is purportedly larger, more vigorous, and has brighter green leaves than White Manaus, however this is difficult to tell unless the two plants are planted side by side. A more compact (less airy) cultivar called BreathlessTM Blush (=’Balbreblus’) has white blooms that are pink-flushed and burgundy-tinted foliage. According to legend, “Silver Fog” features silvery foliage. Diamond DelightTM has a distinctly different appearance, yet it lacks Diamond Frost’s airy appearance and effect because it is considerably shorter, mounding, and has double blossoms.
