How to grow argyranthemums and best varieties

Cheerful flowers to fill your patio with colour  
Which?Editorial team

Something a bit different from standard patio plants like fuchsias and pelargoniums, argyranthemums produce masses of single or double daisy-like blooms from spring through to autumn. They come in a range of colours and their feathery leaves and neat shape make them brilliant for containers. The single-flowered types attract bees and other pollinators and stand up well to the vagaries of the British summer.

Which? Gardening magazine grew a range of popular varieties to see which would give us the best display.

How we test argyranthemums

We chose 10 varieties of argyranthemums that were widely available. We purchased six plug plants of each variety, which we planted when they arrived in May at the Which? Gardening magazine trial grounds at Capel Manor, in north London. For each variety we planted two 20L pots with three plants in each, using a Best Buy compost for containers mixed with a Best Buy controlled-release fertiliser and kept them watered using irrigation. 

We monitored the plants throughout the summer recording: how long the plants were in flower; how much of a show of colour they gave; whether the individual flowers were eye-catching; if the plant was sprawling or compact; whether the flowers were visited by pollinators; if there were any pest or disease problems.

How to grow argyranthemums



Most argyranthemum plugs will arrive in May, after any frosts have passed. If they arrive before this keep them frost free and harden off in a sheltered area before planting out. 

 Plant them into pots filled with a good multipurpose compost such as our Best Buy compost for containers and mix with a controlled release fertiliser. Alternatively you can liquid feed weekly if the plants show signs of finishing flowering. 

 Place them in a sunny spot or partial shade but they will grow toward the sun which can create an imbalanced shaped plant. 

Caring for your plants

Water regularly through the growing season, though argyranthemum are drought resistant. 

Many varieties create very neat dead-heads but others will need dead heading to keep them looking tidy. 


Argyranthemum must be kept frost free, at a temperature above 5°C so can be trimmed back and then kept in a cool conservatory or frost-free greenhouse over winter. 


Slugs and snails

These will nibble at the leaves of young plants. Remove them regularly or use ferric phosphate slug pellets.
