RHS Chelsea Flower Show Plant of the Year Award 2022

The RHS Chelsea Flower Show Plant of the Year award celebrates the new and exciting plants launched at the show. The prestige of winning is recognised worldwide and the show is the ideal global platform for the launch of new plants, which often go on to be bestsellers.

The judges will be looking for the winning criteria which will need to include all three of the following features:

The plant must be genuinely new and offer significant benefits within those features. This will outweigh a new colour on an existing plant for example.

Will the plant stand the test of time? It will need to sustain its popularity to secure a place with those of true significance.

Excellence and impact
Judges (and gardeners) will be looking for the “wow” factor.

The judging panel is comprised of industry experts with a wealth of knowledge and passion who come together, volunteering their time, to make the incredibly tough decision on the winning plant.

Three easy steps to heavenly hanging baskets

Create an amazing display with little effort!

Hanging baskets are an easy way to add interest, scent and colour without much effort! Simply choose your colour scheme, order some hanging basket plants and follow the three easy steps described below.

Your baskets will quickly fill out to provide a stunning display that frames your front entrance, brightens up bare walls and fences, or brings to life a tired garage or shed. Here’s our quick guide to planting up hanging baskets for maximum effect…

1. Choose the right hanging basket

Baskets with side ‘gates’ allow for more plants than traditional top fill types

Any type of container can be used as a makeshift hanging basket – we’ve even seen old clothes used as planters! But the quickest and easiest way is to invest in an Easy Fill Hanging Basket. These are long-lasting and easy to use. Thanks to the little gates around the sides, the roots of your plants won’t be damaged when you tuck them in. For more options, see our collection of hanging basket accessories and decide which style works best for you.

2. Choose the best hanging basket plants

For the best results, decide on a colour scheme before choosing a mixture of trailing and upright plants. Some people prefer a single colour theme, while others opt for a striking contrast such as yellow and blue. If you’re not confident when it comes to choosing colours, opt for one of our themed collections for a tried and tested combination that’s sure to impress. Don’t worry if you run out of time or inspiration. You can also choose one of our high quality pre-planted hanging baskets  – simply suspend it from your wall bracket when it arrives!

  • Geraniums and pelargoniums are a popular choice that come in a variety of colours. Trailing varieties should be planted on the outside of your basket so they can cascade over the edge and provide interest all summer long. Pop an upright geranium in the centre to give your display some height.
  • Fuchsias also make great basket plants. As with geraniums, use trailing varieties on the outside and then upright varieties in the centre.
  • If you prefer a mixed display, begonias, lobelia, petunias, and verbena all make wonderful choices.

When it comes to how many plants to plant in your hanging basket, the more the merrier – pack them in for a full display which will look beautiful cascading and tumbling from the baskets (one little plant won’t have much impact!) As a general guide 5-8 plants should fill a 12″ basket, but if they don’t have a bushy habit, up to 10-12 plants can be used to create a really show stopping display.

If you’re planting up a winter hanging basket, browse our selection of winter bedding plants where you’ll find colourful pansies, primulas, primroses and other hardy varieties.

3. Look after your hanging basket plants

Feeding and watering

The main thing to remember with hanging baskets is that the plant is completely dependent on you for water and nutrition. Plants in the ground can send their roots out to forage for water or nutrients. Those planted in pots and baskets, can’t.

Before planting, add some Incredibloom® to your compost. This will give your plants all the nutrients they need to put on a great display all season long. Tests have shown that this can help your plants produce up to four times as many flowers.

Once planted up, make sure your hanging baskets are kept moist – never bone dry and never sitting in puddles. We recommend a good soaking, before leaving them to drain until the soil is just moist. It’s best to water your baskets early in the morning or in the evening to reduce water loss to evaporation.

Shaping hanging basket plants

Once your plants start growing they’ll take on their own shape. If something starts to look a bit straggly, lightly prune to tidy the shape. Some people like wild baskets and some like neat; it’s entirely up to you. Just make sure that you don’t get carried away – too much pruning can also remove some of the flower buds!

To prune hanging basket plants, cut at the stem just above a leaf joint – the plant will heal over at that point. To stop your plants getting taller, nip out the growing tip at a leaf joint. Sometimes we can be a little fearful of cutting and trimming our plants in case we cause any damage, but there’s not much that can go wrong.
