Hollyhocks in Your Garden: Varieties, Growing Conditions, and Care Guide

Hollyhock (Alcea L.) is an impressive plant belonging to the mallow family (Malvaceae).
Depending on the region, it may also be known as common hollyhock, pink hollyhock, garden hollyhock, black hollyhock, tall mallow, or tree mallow. Hollyhocks are usually short-lived perennials most often grown as biennials, although annual varieties also exist. Their height can reach 2–3 meters, and some species grow up to 5 meters! 🌿

🌺 What do hollyhocks look like?

Hollyhocks are characterized by their unbranched, thick, stiff, and hairy stems, which bear large, palmately lobed leaves and beautiful flowers. Their petals can come in many colors:

✅ White
✅ Burgundy
✅ Red
✅ Purple
✅ Cream
✅ Salmon
✅ Orange
✅ Pink
✅ Yellow

Some varieties are bicolored, and one of the most remarkable is the black hollyhock ‘Nigra’, whose flowers appear almost black.
Hollyhock flowers bloom from June to October, and the fruit is a schizocarp containing numerous seeds that remain viable for up to four years!

💡 Fun fact: Hollyhocks originate from the Mediterranean region, although some sources indicate China as the homeland of these plants.

💚 Hollyhocks in medicine and cuisine

Hollyhocks are not just decorative — they also have medicinal and culinary uses. Even Hippocrates appreciated their health-promoting properties!
The ancient Greeks and Romans used the root, leaves, and flowers of hollyhock in both remedies and dishes.

To this day in Syria, a traditional dish is prepared from mallow roots stewed with onions.
Hollyhock root can also be used to flavor halva and to color wines and liqueurs.

🌸 The Most Popular Hollyhock Varieties

Among the many hollyhock varieties, the most widespread is the common hollyhock (Alcea rosea), also known as the garden hollyhock. Several main groups can be distinguished:

Double hollyhocks – grow up to 3 m tall and have fully double, pompon-like flowers.
Scottish hollyhocks – reach about 2 m and feature hemispherical flowers with petals of equal length.
Chater’s group hollyhocks – beautiful, fully double varieties with slim, compact flower spikes.
Fimbriata flore pleno (Alleghanies) – semi-double flowers with fringed petals.

Additionally, gardens often feature:

Fig-leaved hollyhock (Alcea ficifolia L.)
Wrinkled hollyhock (Alcea rugosa) – with pale yellow flowers
Pale hollyhock (Alcea pallida)

Some particularly attractive cultivars include:
🌿 ‘Creme de Cassis’ – bicolored flowers
🌿 ‘Budapest’ – deep purple-red flowers
🌿 ‘Maroon’ – chocolate-colored blooms 🍫

Hollyhock has anti-inflammatory, expectorant, and soothing properties. An infusion made from hollyhock is used for upper respiratory infections, menstrual pain, and menopause symptoms. It is also used in natural cosmetics for skin care.

🌱 Propagation of Hollyhocks and Seed Sowing

Hollyhocks can be propagated in several ways:

✅ By sowing seeds – in May–June in a seedbed or in pots. Sow the seeds at a depth of about 2 cm.
✅ By dividing the root clump – best done in spring.
✅ By self-seeding – hollyhocks often reseed themselves, producing ready-to-transplant seedlings.

Annual hollyhocks should be sown in March–April so they can bloom in the same year!

🌞 Growing and Caring for Hollyhocks

Hollyhocks are relatively easy to grow, but they do have certain requirements:

Soil: fertile, humus-rich, well-drained, pH 6–7
Location: sunny or lightly shaded, sheltered from the wind
Watering: young plants need more water; older plants should be watered only during droughts
Fertilizing: on poorer soils, apply fertilizer 1–2 times during the season
Pruning: removing spent flowers encourages further blooming

🚨 Hollyhock Diseases and Pests

The most serious threat to hollyhocks is mallow rust — a fungal disease that appears as white or rusty spots on the leaves. To prevent it:

✅ Avoid excessive watering and wetting the foliage.
✅ Use garlic extract sprays or fungicides.

Pests that attack hollyhocks:

Slugs – they eat young plants
Mallow flea beetles – leave tiny holes in the leaves
