One of my most treasured houseplants is my Hoya carnosa `Snowball` or simply known as a hoya or waxflower. Native to Eastern Asia and Australia, H. carnosa is one of 100 species in the Asclepiadaceae (milkweed) family. This tropical vine has dark, green leathery leaves that leak a milky sap when damaged.
My hoya is probably over thirty years old and has been passed down like a family heirloom. It was originally my grandmother's plant, who gave it to my mom, who in turn gave it to me.
Like clockwork, it blooms twice a year, once in July and again in January. It has clusters of attractive, star shaped, white blossoms with red centres. It's spectacular when it blooms. Right now, it's covered with dozens of flowering clusters.
I've already removed a handful of flowers that have finished blooming. The waxy flowers look fake, but I assure you they are real. Once the blooms opens, they are extremely fragrant, especially at night. I'm not sure why the fragrance increases at night, but the sweet scent easily fills my entire house. I've heard of some people removing the flowers because the fragrance is so strong.
So what's the secret to my hoya's success? Simple–I ignore it. I occasionally water it and rarely fertilize it. I did repot it a few years ago and replaced the soil, but other than that, it just hangs in my dinning room window. The new shoots grow quickly and it isn't until they've grown a few feet that they get leaves. There have been a few occasions where I've discovered new vines that had weaved their way through the strings of the blind, with full-sized leaves stuck in between. Unfortunately, the only way to remove them was to remove the leaves and pull the vines through. A hoya will bloom more frequently if placed in direct sunlight, but they'll also tolerate low light.
If you're looking for an exotic houseplant to grow, consider bringing a hoya home. Notoriously long-lived and hardy, these trouble-free plants are ideal for beginner and experienced gardeners alike.
