Do hibiscus plants come back every year? Yes, cold hardy hibiscus plants will go dormant and come back in the spring every year in the right growing zone. Tropical varieties will stay evergreen in warm climates, but are otherwise grown as annuals in cooler climates. A perennial is one that grows year after year.
An annual, on the other hand, does not grow year-after-year. A plant that is an annual can be pruned back to a smaller size if it becomes too large. Annuals can also be cut back if they become too tall or if the soil is too dry.

Are hibiscus bushes perennials?
Be advised that Hibiscus is always one of the last perennials to emerge in spring. Even if you think it is dead, it most likely isn’t. This late start makes up for its vigorous growth rate. These plants are easy to control, which makes them attractive to Japanese beetles. Hibiscuses can be grown from seed, cuttings, or transplants.
The best time to plant them is in late spring or early summer, but they can also be planted as soon as the soil is dry enough to allow them to germinate. Plant them in a well-drained pot with good drainage, and keep them well watered throughout the growing season.
Will a hibiscus plant survive winter?
(That said, if you have a hardy hibiscus, which is sold in the perennials section of your local garden center, that plant can stay outdoors over winter. New growth will be produced in late spring with no need for water, as it will go dormant this fall. You’ll be able to see them all the time, even when they’re covered in snow or ice.
Do hibiscus plants come back after winter?
The shrubby plant can survive an occasional frost but its stems and leaves may die back a bit. As long as the roots don’t freeze, you can remove the dead parts and new growth will grow in their place.
How do I protect my outdoor hibiscus for the winter?
To prepare a hardy hibiscus for winter, apply a heavy layer of organic mulch to the soil around the plant to protect its roots. If you want to keep the leaves from drying out, place frost cloths or string lights over the plant.
Do I need to cut my hibiscus back for winter?
summer. In fact, it is best not to prune at all during the growing season. If you do decide to cut back on the number of blooms in your garden, be sure to do so in a way that does not interfere with the growth of other plants.
For example, if you want to reduce the amount of flowers blooming, you should not cut down too much of the shrub or tree that is producing the flowers. If you are cutting down a tree, make sure that the tree is healthy and that it has not been damaged in any way.
Can you plant hibiscus in the ground?
In the spring or late spring or early summer, plant the flower in full sun. Prepare the soil to plant perennial hibiscus by mixing 1/2 cup of peat moss with 2 cups of well-drained potting soil. Cover the pot with plastic wrap and place it in a sunny location.
Allow the plant to grow until it reaches a height of at least 3 feet. Remove the plastic and allow the plants to dry out completely before transplanting them into a new pot.
Is hibiscus cold hardy?
The plants can survive as low as -20f in the winter. It ignores the frost like a champ. The stems don’t need to be mulched through the summer and spring since it dies back to the ground each winter.
The best way to find out is to plant the plant in the fall and see if it survives. If it does, you can plant it again the following spring. You can also check with your local nursery or garden center to make sure they have it in stock.
What is the lowest temperature a hibiscus can tolerate?
If the temperature is less than 50f, most growth and bloom will stop and the flower size will be smaller. Before the first frost of the season, be sure to move your plant indoors because a freeze will cause the plant to die. The first sign of bloom is when the petals begin to open. This is a sign that the flower is fully developed and ready for the next stage of growth.
The flower will continue to grow until it reaches the size of a large grapefruit. Once the bloom has reached this size, it should be removed from the pot and placed in a cool, dark place for a few days to allow the blossoms to dry out. After the blooms have dried out, you can remove them and place them in an airtight container to keep them from drying out too much.
Should I cut my hibiscus back?
To keep a healthy height, make sure to cut its stems back towards the end as they’re from the previous season and the plant will not bloom from these. It’s a good idea to do that before the leaves start to turn brown. If you want to keep your plant longer, you can keep it in a greenhouse, but be careful not to over-water it as it will dry out quickly.
