Are you looking for a citrus plant that beautifies the landscape and produces delectable sweet-tart fruit? Then check out the calamondin orange tree! Plant expert Briana Yablonski shares how to grow and care for this unique citrus.

In the bright and....

vibrant citrus world, few plants have as many favorable characteristics as the calamondin orange. Its lush green leaves pop out of porch planters and create lush hedges that produce fruit. And oh, the sweet and tangy fruits—they’re not just a tasty treat but also appropriate for everything from cakes to salad dressings. And did we mention the plants can tolerate cold temperatures that zap many other citrus species?

If you’re still unsure about adding a calamondin orange to your garden, I get it. Experimenting with something new can be a bit scary! Yet diving into the unknown is one of the fun parts of gardening. Here is all the information and care tips you need to successfully cultivate these unique citrus fruits.
What Is a Calamondin Orange?
The calamondin orange, also known as calamansi or Philippine lime, is a hybrid citrus plant that’s a cross between a kumquat and a Mandarin orange. Plant scientists once thought the calamondin orange was a unique species (Citrus mitis), but they later determined it was a hybrid. Its scientific name changed over the years, but it’s mostly referred to as Citrus x microcarpa.

Native Range
Scientists think the plant emerged in the Philippines and parts of Indonesia, Malaysia, and Brunei. You can now find it growing throughout Southeast Asia and a few other portions of the world. The Philippines is the major producer of calamansi fruit.

Characteristics
No matter what you call it, the calamondin orange is versatile in the garden and kitchen. Like many fruit trees, the plant’s mature height depends on the rootstock. Wild plants can grow up to twenty feet tall, but dwarf varieties remain under five feet.

All plant sizes have a woody stem that gives way to pliable branches. These branches are covered with shiny, dark green, evergreen leaves. The leaves have an ovular shape with rounded tips, making them stand out from the more pointed leaves of lemons and limes.

Calamondin orange plants produce flowers throughout the year, but spring is the main flowering season. The small white flowers have five petals and emit an attractive fragrance. Upon successful pollination, these flowers turn into fruits that eventually grow one to three inches wide. All fruits start out green, and the mature color ranges from orange to yellow to green. Some varieties also sport variegated fruits.

When you cut into calamondin oranges, you’ll see juicy flesh that resembles other citrus fruits. The flavor is more tart than sweet, with hints of lemon, lime, orange, grapefruit, and passion fruit. Each plant produces unique-tasting fruits, so you won’t know what a calamondin orange tastes like until you try it.

Planting
Growing calamondin oranges from seed isn’t the most reliable planting method, so purchasing a potted plant is the best way to add one of these trees to your home. Although it’s often difficult to find the plants in local nurseries, you can purchase them online. I recommend ordering your plants in the spring through fall since cold winter temperatures can damage the plants during shipping.

Before you choose a plant, be sure you research the cultivar. As I mentioned above, some calamondin oranges remain small enough for planters, but others grow into small trees. Pay attention to the rootstock and choose one that matches your needs.
