Plants That Grow in Two Days

Corn

• Corn plants, if given enough light, water and nutrients, can grow in two days. Corn farmers have reported that they can hear corn growing in the summer as it will grow up to 6 inches overnight in warm weather. When looking for corn kernels that will grow in two days, it is best to buy them from a garden center rather than trying to grow from fresh corn bought at the supermarket.

Field Mustard

• Field mustard (Brassica rapa), also known as turnip mustard, is a fast-growing, leafy green vegetable that is often used in classrooms to teach children about the growth cycles of plants. Brassica rapa is an upright plant that produces large leaves, long fruits and golden yellow flowers. The turnip mustard plant can grow from a seed to a small plant in two days and will produce flowers after about 14 days of growth.

Grass

• Many types of grass are also fast-growing and can grow in two days if given enough water. Grasses that can grow in two days include Bermuda and Napier grasses, though even common lawn grasses, such as ryegrass and fescue, also come in fast-growing varieties. Bamboo is also a type of grass, and it is so fast-growing that it is considered invasive in warmer areas.

Vines

• Many vine plants will grow quickly, either climbing up stationary objects, such as fences, or spreading over the ground. In general, woody vines, including grapevines and English ivy, will grow more slowly than soft vines, such as beans or morning glories. Bean plants can grow in two days if the beans are not dried, making these plants suitable for classroom demonstrations of plant growth. Fast-growing flowering vines include honeysuckle, clematis and trumpet vines.

Weeds

• Plants that are commonly considered weeds are often thought of as invasive plants because they are quick to grow, so there are many so-called weeds that will grow in two days. Clover is one such plant that can grow in two days and cover a large area of ground. Kudzu vines are also considered weeds in many areas, and they can grow several inches in two days.
