As far as tropical houseplants go, one of the most popular and easy-to-grow species is the rubber plant (Ficus elastica). Their oversized, glossy green oval leaves make a statement in any bright, warm room. If you want to make even more of an impression, opt for the easy-to-find cultivar ficus tineke (Ficus elastica 'Tineke'). The variegated rubber plant, as it's sometimes known, often features striking reddish-pink tones on the outside of the green and cream foliage, and the sheath at the top of the stem is also a deep burgundy-red color. Ficus Tineke is grown as a small ornamental tree or bush in use indoors. It grows outdoors in USDA Hardiness Zones 10b to 11. Outdoors trees may reach between 50 ft. tall or more. When used as a houseplant, Tineke grows up to 2 ft. - 10 ft. tall. Ficus Elastica grows around 24 in. (or 60 cm) per year. With this houseplant, growth tends to be a case of slow and steady wins the race. These plants appreciate it if you let the top couple of inches of potting mix dry out to the touch in between waterings. So watering once every 1 to 2 weeks during the growing season is usually enough, depending on the light and humidity in your home. As you would expect of a tropical species, ficus tineke appreciates warm temperatures and moderate humidity. Ideal temperatures range from around 60 to 75° Fahrenheit.
