Best plants for pots all year round at a glance:
Pot plants, such as primroses, are hardy and easy to grow – perfect for planting a spring trough. Once established, they are low maintenance too. Also, many of the flowering plants attract pollinators, encouraging wildlife to frequent your garden. In general, pot plants need well-draining soil and regular watering and while most will enjoy full sun, some species will be shade-loving plants.
When choosing plants for pots that will thrive all year round, it's essential to consider your climate and the amount of sunlight the pots will receive. Choose a good fertiliser and water your buds more regularly than bedding plants, as pot plants have a limited volume of soil from which to draw nutrients and water. Finally, if you don't know your perennial from your biennial, scroll to the FAQs below.

Best geranium for pot planting
www.thompson-morgan.com
Thompson and Morgan claim this Geranium 'Best Red' F1 Hybrid had outperformed other geraniums in their trials. It's a half-hardy perennial that keeps its vibrant red flower throughout summer and well into autumn.
This needs to be planted in sun or semi-shade in light, non-acidic, well-drained soil. Geraniums need to be kept frost-free as they are only half-hardy, and regular deadheading will encourage more flowers. Alternatively, geraniums can be overwintered in a greenhouse, otherwise, treat them like an annual.
Reviewers report these plug plants can be slow to get growing, but once they are established will offer you a vibrant show of colour for many months of the year, with the flowers retaining their shape even as they begin to fade.
Pros
- Top performing geranium in Thompson & Morgan's trials
- Long flowering period for extended colour
- Versatile planting options
Cons
- Only half-hardy
Format: | Choose from garden ready plants and plug plants in various quantities |
Height: | 45cm |
Aspect: | Sun or semi shade |
Flowering time: | June–October |
- Half-hardy perennial
- Pelargonium species

Giving a bouquet of chrysanthemums traditionally shows our love for someone dear. Chrysanthemums symbolise joy, love, and optimism in many cultures, so what could be better than to grow them in your garden?
These tall and vibrant Chrysanthemum Amiko Violet blooms attract butterflies and bees and provide long-lasting flowers to perk up your pots.

They like full sun and well-drained soil, making them an ideal plant to grow in pots.

FAQs
What does perennial mean?
A perennial refers to a plant that continues to grow year after year; re-growing each year from the same root system. This is the kind of plant to opt for if you want it to come back year after year.
What does annual mean?
An annual plant completes its entire lifecycle, from germination to seed production, within a single growing season, typically one year. Annuals are fun to experiment with if you want to add some seasonal variation to grow garden's growth.
What does biennial mean?
A biennial plant takes two years to complete its lifecycle, growing leaves in the first year, then flowering and seeding in the second. This takes a bit of patience but the floral display you will eventually enjoy from the likes of delphiniums, foxgloves, and some polyanthus will be worth the wait.
What does hardy mean?
Hardy refers to plants capable of surviving cold temperatures and adverse conditions, often without requiring special protection during the winter, although raising their pots off the ground to protect from hard frosts is advised.
What does half-hardy mean?
Half-hardy refers to plants that can tolerate mild frost but are not fully cold-resistant, often requiring protection in colder climates or seasons. These are plants you want to be able to pop in your garden greenhouse when the weather gets nippy.
How do I care for plants in pots?
Proper care, including watering, fertilising and repotting is essential to keep your pot plants thriving throughout the year. Always check the specific requirements of each plant to ensure they will do well in your particular environment. The RHS offer extensive guidance on container planting, including what type of container to choose, when to plant and what type of compost to use.
