Your Essential Guide to Choosing Chrysanthemum Varieties

Chrysanthemums, often referred to as mums, are a stunning addition to any garden. With their vibrant colours and varied forms, they can brighten up your outdoor space from late summer through to autumn. As we move through 2026, understanding the different varieties available can help you make informed choices that suit your garden's style and conditions. This guide will provide you with practical advice on selecting the ideal chrysanthemum varieties for your needs.

Understanding Chrysanthemum Types

Chrysanthemums come in numerous types, but they can generally be classified into three main categories: florist types, garden types, and hardy types. Florist types are often found in floral arrangements and are bred for their size and colour. Garden types are ideal for landscaping and typically include varieties such as the spoon and pompon types. Hardy types are known for their resilience and ability to withstand colder temperatures, making them suitable for outdoor gardens in various climates.

Choosing Based on Flower Form

The flower form is a crucial factor in selecting chrysanthemum varieties. There are several forms to consider, including decorative, pompon, and daisy types. Decorative chrysanthemums have large, fluffy blooms and are perfect for creating eye-catching displays. Pompon types feature small, round flowers that add texture to arrangements, while daisy types have an open-centre bloom resembling traditional daisies. Evaluate your garden design and choose a flower form that complements your aesthetic.

Colour Selection

Chrysanthemums are available in a rainbow of colours, ranging from whites and yellows to deep reds and purples. When selecting the colour of your chrysanthemums, consider the existing colour palette of your garden. For a harmonious look, choose colours that complement your other plants. Alternatively, for a bold statement, opt for contrasting hues. Remember that some varieties may change colour slightly during the season, so be sure to check for colour stability.

Growth Habit

Different chrysanthemum varieties also exhibit varying growth habits. Some grow tall and upright, while others are more compact and bushy. If you have limited space or are looking to create a border, consider planting lower-growing varieties. Taller varieties can be used as focal points or backdrops in your garden. Always check the mature height of each variety to ensure it fits well within your garden layout.

Hardiness and Growing Conditions

When choosing chrysanthemum varieties, it is essential to consider hardiness. Some varieties thrive in cooler climates, while others prefer warmer conditions. Check the hardiness zone for each variety and match it with your local climate. Additionally, consider the soil type and drainage. Chrysanthemums prefer well-drained soil with a pH level between 6.0 and 7.0. If your garden has heavy clay soil, consider amending it with organic matter to improve drainage.

Timing for Planting

Timing is key when it comes to planting chrysanthemums. In the UK, the best time to plant them is in spring after the last frost. This gives the plants ample time to establish before blooming in autumn. If you opt for autumn planting, choose hardy varieties that can survive the winter. Always check the specific variety’s recommendations, as some may have different planting requirements.

Pest and Disease Considerations

Chrysanthemums can be susceptible to pests and diseases such as aphids, spider mites, and root rot. When selecting varieties, consider their resistance to common pests and diseases. Look for healthy plants at your local garden centre, and always inspect for signs of distress before purchasing. Regularly monitoring your plants and maintaining proper care will also help keep them thriving and disease-free.
