Working on your garden can be a very enjoyable hobby, but sometimes you simply wish you could see results in a shorter period of time. Knowing which flowering plants grow fastest will allow you to garner nearly instant results from all of your hard work. Some flowers take just weeks to sprout and bloom, even when planted by seed.
Gaura plants are quite large, growing up to four feet, with patches of small white flowers covering the stems. They are often planted in the front of gardens because they are almost "see-through," allowing viewers to notice the back of the garden as well. Gaura plants require full sun and well-drained soil, thriving in both very humid and drought-like environments. For this reason, they are a popular flower choice for beginning gardeners.
Blanket flowers grow up to three feet tall in full sun and well-drained soil. They are two-toned daisies, with their petals possessing a ring of yellow around a red-brown center. They tolerates drought and self-sow easily.
Blackberry lilies are known for their petals, which are speckled red on an otherwise orange surface. They need to be mulched during winter in cold areas, but their seeds take just three weeks to sprout. With fast growth following sprouting, the blackberry lily may be the fastest-growing perennial on the planet.
Rose campions grow to about two feet tall, displaying cerise flowers with silver foliage. They thrive in rich, well-drained soil and full sun. Despite a short lifespan, rose campions self-sow rather easily, making them an excellent choice for novice gardeners.
With their golden yellow petals and dark center, black-eyed susans are very popular. With full sun and well-drained soil, the daisies grow in summer, resisting drought quite easily. They are perhaps the most common perennial flower used in gardens today.
