In Michigan, October is the best month to plant winter-blooming, deer-resistant bulbs.
Here is the fall version of the same topicdeer-resistant bulbs that may be planted in the fall, which is similar to an earlier post on deer-resistant summer bulbs, rhizomes, tubers, and corms. In Michigan, October is the best month to plant winter bulbs since the soil is still warm and the air is still somewhat warm. These circumstances support the development of early roots in the absence of top growth, which is a crucial initial step in getting bulbs ready for their essential winter cool down and subsequent next life stage. Since the majority of bulbs require a cool down in order to bloom, northern climates are where spring flowering bulbs are most frequently produced.
If you are in a region where deer are prevalent, you could have previously experienced unsatisfactory results with spring bulbs. Even though we want to blame the deer, those losses can be reduced by choosing the right bulbs. To put it another way, avoid the tulip! Tulips are a favorite food of deer, but the good news is that they stay away from a wide variety of other bulbs. The reason for this resistance is more likely because deer-resistant bulbs generate blooms that are harmful to deer and other animals and may have potent odors.
See some of the intriguing deer-resistant choices listed below. Choose the bulbs that will grow best in your environment before you plant them. The majority of bulbs require a loose, rich, well-draining soil, while there are a few kinds that do well in moist soils. Bulbs that spread will need space to flourish. Consider planting a variety of bulb kinds with varying bloom times rather than just one type for long-lasting beauty and pollinator support. Finally, combine deer-resistant plants and bulbs to create arrangements that ward off deer rather than serve as a buffet. See: for further information on how to plant the bulbs themselves.
Ground cover bulbs
Snowdrops (Galanthus spp.), Crocus (Crocus spp.), Glory-of-the-Snow (Chionodoxa spp.), Squill (Scilla spp.), Grape Hyacinth (Muscari spp.), Windflower (Anemone spp.), and Star Flower are listed in order of early to late spring bloom time (Ipheion spp.)
These bulbs are grouped together because they all have low, naturalized growth rates and can function as temporary ground cover. They can be planted in a range of locations, including:
- In flower beds, there is no need to worry about plant competition.
- Woodlands that are partially shadowed, either with year-round dappled shade or with spring sun before the tree leaves open.
- Since most ground cover bulbs bloom before grass takes control, lawns can compete with grass.
Additionally, if you grow a mix of these plants, both you and pollinators will benefit from a longer succession of blooms throughout time. For instance, by growing Snow Drops, Glory-of-the-Snow, and Grape Hyacinth in the same location from late March to early May, you can extend the aesthetic and pollination benefits over a longer period of time.
As seen in the above video, snowdrops are one of the earliest bulbs to bloom and provide honey bees with nectar and pollen at a time of year when such resources are in short supply.
Daffodils
Many gardeners already know that daffodils are resistant to deer, so they might consider this group to be very common. But did you know that there are 32,000 different varieties of daffodils divided into 12 separate divisions? Consider the possibilities when you combine these factors with the fact that daffodils come in enough different variations to bloom continuously throughout the entire spring. Some varieties even have surprising characteristics like “gardenia-like fragrances, pink tones, small cups, and ruffles.”
Hyacinths and Hyacinthoides
These are the bulbs that produce calcium oxalate, which can also be found in several leafy green vegetables and other deer-resistant plants like sorrel, rhubarb, and skunk cabbage (e.g., spinach). Hyacinths have large quantities of calcium oxalate, which is poisonous. Fortunately, hyacinths also release a biochemical with a strong aroma that makes them pleasing to us while discouraging deer from approaching.
Fritillaria
Until one comes across it in the early spring and wonders what it might be, this bulb is a little mysterious. This is due to the fact that the taller kinds of Fritillaria frequently have more leaves and resemble perennials rather than bulbs. Even while some types are short, taller varieties, like F. persica, can grow to a height of 3 feet, so only a few are required in a flower bed to attract pollinators and neighbors.
Intriguingly, Fritillaria species may also draw solitary bees while having evolved to be pollinated by birds in their natural habitat. In Michigan, Fritillaria spp. may be sensitive to cooler growing zones and may require a covering of mulch to endure several winters.
Ornithogalum
This group, sometimes known as Star of Bethlehem, comprises numerous taller forms in addition to a short ground cover variety (O. umbellatum) (e.g., O. ponticum, O. nutans). O. umbellatum is a competitive plant that can be aggressive in some environments (some states consider it to be an invasive noxious weed), yet taller versions are controllable and rather unusual. The taller Ornithogalum species resemble the Camas deer-resistant bulb in terms of appearance, blooming season (May–June), and deer resistance.
Leucojum
Another underused bulb, this one bearing small, green and white flowers on tall stems. It blooms in May and June, when other bulbs like Ornithogalum and Allium are also in bloom. It prefers wet soil and some shade. Leucojum spp. can naturalize in soils that remain constantly moist because they are more tolerant of damp soil than most bulbs. Gardeners who might be tempted to buy early summer plants that deer love to devour have options thanks to these and other late blooming bulbs with deer resistance (e.g., hostas, roses).
Colchicum
These bulbs, which are planted in the fall, have two active growth phases that are separated by a summer slumber. Without flowers, green leaves appear in the spring, and in the summer, the plants entirely disappear. Early in the fall, colchicum begins to blossom (no leaves). Given that an alkaloid poison known as colchicine is most abundant in the flower, the flowering stage of this plant is probably the most deer-resistant stage of the plant.
Do deer enjoy tulips as food?
Even though we like animals, we detest seeing a herd of deer lazily grazing in our garden or squirrels playing on the lawn while their cheeks are bursting with Crocus bulbs. Except for the gleefully bumbling bees, butterflies, and hummingbirds, our garden is not meant to be an all-you-can-eat buffet.
The unfortunate truth is that tulip and lily blossoms make for excellent deer treats. Deer may calmly hold off on eating until the flowers bloom or the spring buds have fully inflated. On a smaller scale, rabbits may eat low-growing flowers as well as emerging stems and foliage.
To eat appetizing roots, prairie dogs, voles, chipmunks, and gophers burrow underground. They may even pull at or eat the bulbs themselves. Freshly planted bulbs, especially Crocus, may be dug up by squirrels and chipmunks and replanted for unexpected spring gardens. We haven’t gotten any squirrel testimony to support the rumor that Crocus tommasinianus cultivars are unappealing to squirrels. Moles that just hunt grubs cause damage to gardens and plantings. Because sluggish, vegetarian voles utilize mole tunnels, it is wise to put grub-proof treatments on lawns and gardens to reduce
There are several flower bulbs that deer typically ignore, so we don’t need to give up hope. Animals will eat anything they can get their hands on when they are starving. Deer may even consume holly leaves with strong serrations. The varieties of flower bulbs that they often avoid eating are listed below. Visit our dedicated Deer-Resistant Kinds search page for a detailed list of particular varieties.
Is daffodil food for deer?
Deer and rodents can do serious harm to tulip and crocus plantings, but there are several bulbs that animals avoid, daffodils being one of them.
The list of our bulbs that deer typically ignore is provided below. The only plants genuinely resistant to deer and rodents are those in the Amaryllis family, which also includes daffodils, snowflakes, and snowdrops. They contain lycorine, a deadly, bitter chemical that no creature will eat. Deer dislike the other bulbs on the list. For rodents, some are also unpleasant. Deer will often avoid these bulbs, but if the plants are directly in their path or if hunger compels them to do so, they may take a nibble.
Do tulips and daffodils appeal to deer as food?
The king of deer-resistant bulbs is the daffodil. They contain lycorine, an unpleasant alkaloid that is even harmful to deer, rabbits, and other mammals. And if you still believe that all daffodils have the same yellow flowers, you haven’t been paying attention! Daffodils come in a wide range of eye-catching varieties and colors, including creams, oranges, peach, and pink, as well as some with ruffled cups and even double flowers. Plant a variety of early, middle, and late-blooming bulbs to extend the season since different varieties bloom at various periods throughout the spring. The top 10 daffodil bulbs to plant this fall are listed below.
Do tulips have any deer resistance?
There are also several bulbs that are critter resistant, including tulips, for those of you who have deer, squirrels, rabbits, chipmunks, and other vermin that like to destroy the spring garden before it even starts. These flowers are referred to as Species Tulips. These are the original wild tulips that were gathered in places including Southern Europe, Africa, the Caucasus, Persia, and more. Wild species are still found and grown for commercial sale today.
Recognize that these wild species frequently undergo significant changes after being gathered and professionally cultivated. Their height may increase, and their flowers’ size may increase along with the vibrancy of their colors. That’s okay since these modifications would occur even if you found them in the wild and carried them into your own gardens. Most wild animals get that way with loving care.
Species The Tien Shan mountains in Kazakhstan are among the Central Asian mountains where tulips first appeared. They spread out across hillsides and meadows in these rough areas, frequently growing at heights above 10,000 feet. They were gathered from these areas and transported west through the trade routes to the westernmost reaches of the Ottoman Empire by resourceful travelers.
These tulips arrived in Europe in the 16th century after being smuggled out of Constantinople by the Flemish ambassador, Ogier de Busbecq, in his diplomatic luggage. These tulips started to appear in groups in France and Italy’s terraced vineyards and olive groves, where they thrived in the far more friendly surroundings.
You have now met 8 different species of tulips. This week, we’ll introduce you to four more of these unique plants that are now grown for commercial purposes.
