The most popular plant for home decoration is the dahoon holly (Lilium longiflorum). It grows up to 30 feet tall and has a diameter of 1 foot. It produces white flowers with red centers. The leaves are usually greenish-white or grayish-green and grow from the base of the trunk to the top of its branches. Its fragrance is pleasant to smell when it blooms in springtime. Dried flowers make wonderful gifts for birthdays, weddings, anniversaries and other special occasions.
Dahoon holly trees are native to North America but they have been introduced into many countries around the world including Australia, Canada, China, France, Germany, India, Japan and New Zealand. They are very hardy plants that can survive harsh winters.
The best time to plant them is between April and June because they need warm weather during winter months.
In the United States, there are several varieties of dahoon holly. Some of these include:
1) White Mountain Dahoon Holly (Lilium lilidum) – This variety is called “White Mountain” because it looks like snow on a mountain.
It’s name comes from its color which resembles white snow. White Mountain Dahoon Holly is a slow growing tree that needs at least six inches of soil to grow well.
2) Henry Long Dahoon (Lilium lancifolium henrylongii) – Its yellowish-green flowers bloom from July to September.
It is a very hardy kind of plant that can survive in cold winter areas.
3) Pink Dome (Lilium lancifolium) – This dahoon holly tree flowers profusely, and has a pleasant smell.
Its leaves are small and glossy. It has a high drought tolerance and can survive in dry and nutrient-poor soil.
4) Ruby Dome (Lilium rubrotemptrum) – The ruby dome dahoon holly is the most popular kind in North America.
It has dark red flowers with a black center that bloom from July through September. It’s glossy green leaves make it the perfect tree for home decoration in springtime.
5) Royal Purple (Lilium lancifolium) – This is a very rare kind of dahoon holly.
It has large flowers with purple petals and a black center.
6) Sunshine Sensation (Lilium lancifolium “Sunshine Sensation”) – This is yet another beautiful kind of dahoon holly.
It blooms in springtime and grows up to 3 feet tall.
7) Glowing Embers (Lilium lancifolium “Glowing Embers”) – This is a relatively new dahoon holly tree that was bred for the purpose of creating more heat in colder areas.
It is a cross between two popular dahoon hollies. Its orange, yellow and red flowers bloom from July through September.
It usually takes two to three weeks for your dahoon holly tree to be shipped to you. You need to allow 14 days for the blooming process.
You can get one from a greenhouse or nursery. If you want to plant it in your yard, you need to prepare the land first.
If you have back problems, don’t lift your dahoon holly tree from the pot. Instead, push the container a little bit at a time until it is close enough that you can grab hold of the plant and pull it out.
Once you have your tree out of the container, you need to plant it immediately. Dig a hole that is twice as wide as the tree’s current container and just as deep.
Remove the plant from its container and place it in the hole. Fill the hole halfway with soil and tamp it down firmly. Fill the rest of the way with more soil and tamp it down again.
If the tree is too heavy to lift, you can drag it instead.
Water your dahoon holly tree well after planting and keep the soil moist for the first two weeks after planting. Water it normally after that.
Your dahoon holly tree can survive in almost any condition as long as you plant it in well-drained soil. It can grow in semi-shaded or sunny areas.
It can also grow in both acidic and alkaline soils (pH 4.5-8.5). It can grow at altitudes of less than 3,000 feet.
If you want to take your dahoon holly tree to campus, you can keep it in a pot. However, don’t let the pot stay wet for long periods of time.
Let the soil dry out a bit before watering it again.
You can prune your dahoon holly tree any time of the year as long as you do it right after it has flowered. Cut off any dead, damaged or weak branches.
Dahoon holly trees can tolerate extremely cold temperatures. In fact, it can grow even in snow!
Just be sure to protect it from extremely harsh winds.
Sometimes your dahoon holly tree may get aphids. These are small green, yellow, black or red bugs that suck the sap out of your plant.
Aphids can be dealt with using insecticides or by washing them off with water.
If you don’t want to bother dealing with aphids, there is a variety of dahoon holly tree called ‘Aphid Resistant’.
Diseases that commonly attack dahoon holly trees are root rot, crown rot, leaf spot and blight. These can be prevented by making sure the soil where you plant your tree has good drainage.
If your tree gets infected with disease, there is not much you can do except to cut off affected limbs and leaves. If too much of the tree is affected, you may have to cut it down altogether.
It’s important that you keep your dahoon holly tree well-watered while it is germinating. After that, water it normally and make sure that the soil always stays moist (but not soggy).
Dahoon holly trees prefer full sun but can survive in shady conditions. The more sun they get, the better they grow.
