About Hollyhocks
- Native to Asia and Europe, hollyhocks are biennials. This means that you won’t get to witness the beauty of the hollyhock flowers until a year after you have planted them. First, the tall stalks will begin to grow, consisting solely of the plant’s foliage. Once these stalks reach their final height, flowers will bloom on them.
- They can self-seed, so you don’t have to plant hollyhocks every time. When you have the first round of established plants, new plants can sprout the following year in the same place. So, you will be able to enjoy seeing hollyhocks in your garden every summer.
- Hollyhocks and hibiscus are related, given that they belong to the same family, Malvaceae.
- The Alcea plant can have health benefits, from treating sore throat to digestive problems. For this reason, hollyhocks continue to be used for medicinal purposes.
- In traditional herbal medicine, the hollyhock roots have proven to be helpful, while the plant’s flowers can be used to make a lotion that can alleviate dry skin and sunburn symptoms.
- An interesting fact that not many people know is that hollyhocks flowers can be used as dolls. In order to make one of your own, you need a fully-bloomed flower as the skirt and a partially bloomed one for the body. As for the head, you can use the flower bud. Making hollyhock dolls is a great activity to try with your kids.

Growing Hollyhocks
In order to grow hollyhocks, you need to ensure you have a spot in your garden that will allow this astonishing plant to soak in the sun, so to speak. This is of the utmost importance, given that hollyhocks require full sun to grow. These plants look lovely in an outdoor landscape, especially when they reach incredible heights. Not only are hollyhocks beautiful, but they truly – and literally – stand out in a garden!
What’s more, these sun-loving plants grow best if they are given support by a fence, stake, or wall. Because they grow tall spikes on which the hollyhocks blooms grow, it is necessary to protect them as much as possible from dangers, like strong winds, reducing the risk of them being blown over.
Therefore, finding an area where there is total sun exposure and the soil is well-drained is strongly advised to grow hollyhocks. A noteworthy mention is that partial shade is accepted. However, gardeners should try to avoid these areas if possible and ensure their hollyhocks receive enough direct sunlight. In the spring, it is recommended you apply fertilizer or compost, as hollyhocks grow better from a light application by gardeners.

Planting Hollyhocks
It is crucial to point out an important detail when it comes to learning how to plant hollyhocks. Many novice gardeners plant hollyhocks in dry soils. This should be avoided at all times, given that these plants require well-drained, moist, and rich soil. It is a common rookie mistake to plant hollyhocks in soil that is too dry for them to grow properly. Luckily, we have got you covered!
The ideal period to plant Hollyhocks depends on how you choose to sow the plant’s seeds. If you wish to sow seeds undercover, then the best period is from April to May. However, there is also the option of sowing them outdoors, in which case you can do so a bit later, in May and June. If you choose to plant Hollyhocks in the summer months, the plant’s flowers will bloom the following summer, given it is a biennial plant.
When it comes to soil types, the ideal ones are chalky, sandy, or loamy. Before you plant your Hollyhocks, make sure you get a stake that can support their heights. Alternatively, plant them by a wall or fence to support the growth. As mentioned earlier, hollyhocks can reach two or three meters, so it is vital you plant them accordingly.
Watering Hollyhocks
An interesting fact to know about hollyhocks is that they need to be watered regularly in the beginning, when they are still developing. This is in order to keep the soil moist and ensure it won’t get dry during the growing period.
Once hollyhocks are established and fully grown, the plants become more drought tolerant. However, this doesn’t mean that you should stop watering them. Simply reduce the amount of water while always making sure that the soil moisture is maintained. As mentioned before, any dryness can be harmful to Hollyhocks.
Another noteworthy mention would be to always water hollyhocks from below, at the base of the plant. Wetting the Alcea foliage can cause leaves to develop various diseases. Plus, if the garden hose flow is too powerful, it could easily break the Hollyhocks foliage when you try watering the plant from above. Therefore, this should be avoided at all times.

Propagating Hollyhocks
If you wish to propagate hollyhocks, what you need to know is that the best method to do this is to leave flower stalks in place, as they can self-seed by division. Another simple way of growing and propagating hollyhocks is from sowing the seeds yourself during springtime.
Hence, hollyhocks are a type of plant that can be propagated by both division and seed. The former is relatively easy to do. During the season when hollyhocks are not in bloom, like winter, spring or fall, it is essential to start digging the soil around already established plants, loosening it. Once you have done this, you can carefully pull the stalks out of the ground so you can put them in water. Be careful not to break off their long roots when doing this.
Next, these stalks with long roots that you’ve managed to dig up and collect can be planted directly into the garden. Similar to how you sow the seeds of hollyhocks, it is essential you pick a suitable place for them. This means moist and rich soil in an area with a lot of sun exposure so that the hollyhocks can enjoy direct sunlight most of the day. Don’t forget to support the plant’s growth by planting it next to a fence or using a stake to uphold the plant.
In Conclusion
Alcea or hollyhocks are one of the oldest cultivated flowers, dating back to ancient times, and continue to be a preferred choice for gardeners nowadays. Given the plant’s tall stalks full of beautiful flowers in striking colours, there is no denying that many want to add them to their gardens.
Hollyhocks look best when planted in an outdoor landscape, with denser and smaller plants and flowers in front of them, which can complement the imposing height of the Alcea plant. Hollyhocks are biennials, not difficult to plant and grow, and they can self-seed, so there is no need for you to plant them every year. This ensures that every summer, you get to witness the Alcea blooming.
