Hollyhock flower is also known as Alcea rosea, a native plant of south china, imported to Europe during the 15th century. It is an ornamental dicot flowering plant belonging to the Malvaceae family.
Hollyhocks in a biennial plant mean it’s a complete life cycle in a span of two years. In the first year, it spent time growing stem, foliage, and storing energy. In the second year, the stalk shoots up and bloom numerous flowers and forms seeds.
However, some varieties grow perennial and bloom flowers in the first year of planting if planted in early spring or started indoors in winter.
This plant does not need much maintenance but it is required to protect from pests and diseases. Here in this post, I’ll describe Hollyhocks how grow and care for them.
Let’s get started:

It’s a classic cotton garden staple that blooms in mid-spring with multiple flowers on tall spikes about 6-8 feet tall and 1-2 feet wide. Grows well in full sun and partial shade mostly in hardiness zone 3-8.
Hollyhocks blooms have single or double-cup-shaped flowers that look similar to Japanese anemones. The flowers grow with or without stalk on a tall spike.
It’s available in many varieties with different shapes and colors including pink, yellow, white, purple, red, and even black.
In the blooming season, the spikes are decorated with numerous flowers from top to bottom. Their leaves are large, coarse, and palmate in size.
Hollyhocks are not reported toxic when ingested by pets or humans. But, their leaves and stems irritate when the small glass-like fiber is touched or brushed against them which is obviously a very rare condition.
Always plant them in rich compost soil. The soil pH is usually not a problem for them, they grow in neutral soil pH. Prepare the soil with compost and sand soil for good drainage.
Water regularly to keep the soil moist but avoid overwatering. Hollyhocks need regular watering in the starting once they get established, they are drought tolerant. The best way is to water when the upper surface of the soil looks dry.
Always water onto the base of the plant, avoiding wetting stem foliage. The wet parts of plants increase the chance of fungal diseases leads to disease leaves.
Pruning & Cutting
Prune yellow-brown leaves or dry flowers from the plant, these parts look dead but they keep sucking energy from the plant once you remove them the energy redirect for new growth.
When the flowers bloom cut 5-6 inches of the stalk and decorate these flowers in vases. Cutting the blooming branch is important to encourage new flower growth.
Pest and diseases
The hollyhocks often suffer from rust, a fungal infection that first appears like a small yellow spot then develops into brown rust the colored bumps on both sides of the leaves.
This fungal disease is caused due to overwatering and improper air circulation.
To prevent this water the plant only when its soil looks dry. And for proper air circulation, plant each hollyhock at least 1 foot apart.
Any leaves showing the susceptibility to rust should be removed from the plant and get destroyed before they spread to the whole plant.
If you often suffer from rust in your garden, then consider growing rust-resistant cultivars such as “Alcea rugosa” varieties.
