Annuals - Bedding Plants
Bedding plants epitomize formal gardening and the UK is famous throughout the world for this type of multi-coloured display.
In the 1980s and 1990s regimented rows of Alyssum, Lobelia and Marigolds were a regular sight in front gardens. Nowadays such disciplined plantings are the preserve of local authorities and public parks whilst in domestic gardening there has been a swing towards less formal planting schemes.
There is still a place for bedding plants in private gardens and where a gardener requires a brilliant flash of colour that can be quickly produced it is bedding plants that fit the bill.

- Easy to grow and a favourite of 'older gardeners'!
- At one time white Alyssum was used extensively in association with blue Lobelia.
- Provides a vivid display while it lasts but it tends to be short-lived and when flowering is finished it can lend an untidy appearance to a mixed bed.

Impatiens
Marigold
Pelargoniums
Tagetes
- Seed catalogues usually list a plethora of different 'types' of marigold including African, American, French, Mexican and Triploid and the lines between each are very blurred!
- Many of the plants have a pungent smell and some gardeners plant marigolds next to their tomatoes to deter insect pests.
- Marigolds are amongst the easiest of all plants to grow from seed - an ideal plant to nurture the interest of youngsters.
In the UK the name 'Tagetes' is normally reserved for a member of this genus that has feathery foliage and a multitude of small flowers. There is not a genus called 'Marigold'!

Papavar
Pelargonium
Philadelphus
Philodendron
- The plant is a native of South Africa.
- Amongst the most reliable of all bedding plants because it flourishes even in extremely hot and dry conditions.
- Can be grown from seed but make sure you buy F1 hybrid varieties. Non F1s are unpredictable and tend to flower very late.
- F1 hybrid seed is expensive but worth it.
- Choice plants can be dug up and saved for the next year provided that you can keep them in a frost-free place over winter.
