Take advantage of our fantastic bumper pack of summer perennials to fill your garden with plants that will die down each winter and come back again in the spring year after year. Our team on the nursery will carefully select 3 different trays/varieties in order to provide you with a prolonged garden display, or why not share with friends and family if you have less space.
Seedlings are our youngest and smallest plug plants, for the best value and masses of summer colour year after year. The collection will include a mix of varieties and colours and will need to be potted on, into small pots around 7-9cm in size for a month or so in season to allow them to establish into bigger and stronger plants before being planted into the garden to flourish.
How you will receive your plants:
Selected by our team of experts and sent from our nursery, you will receive your seedlings in plug trays in a box. These are designed to keep your plants secure and to prevent damage in transit. Seedling plugs will require growing-on in larger pots.
Can’t plant straight away?
If you aren't able to pot your plugs up straight away then ensure they stay moist. You can place your plugs on a saucer or tray of shallow water so they are able to stay hydrated. Aim to have your plugs potted on within 3 days.
Planting tips and hints:
Potting seedling plugs on: On arrival place your plug trays in shallow water to allow them to soak ensuring the rootballs are moist. Use the end of a pencil or a narrow dibber to gently tease your plugs out of their trays. Choose potting on pots approximately 3 inches in diameter to plant your plugs on. Fill the pots with quality potting on compost and tap down until level. Use your pencil to make a hole in the top of the compost and place your plug plant in, gently pushing around the base of the plant. Repeat this process for all of your plugs and then place them in a tray and thoroughly water with a watering can using a fine rose to prevent the compost from being displaced. Grow your plants in a cold-frame, large sunny windowsill, or greenhouse. Water every 2-3 days and more frequently if sunny to prevent drying out.
Hardening off: Once your potted on plants reach a good size and are ready to plant out in their final location, the first step is to harden them off before moving them outdoors permanently. This involves simply placing them outdoors during the day and back undercover at night to allow them to get accustomed to the lower temperatures. Once they have been hardened off for a week your plants should be ready to plant out in their final location.
Planting in containers: Plant approximately 8-12 plants per 30cm container. Sprinkle a layer of stone or gravel in the bottom of the container to aid drainage. Use a high-quality young plant or general-purpose compost spaced evenly with enough space to allow the plants to grow. Mix in a slow-release granular fertiliser in the compost before placing the plant to provide plenty of nutrients. Water thoroughly once planted up. Continue to water every 3-5 days and don't allow the container to dry out.
Planting in the ground: Dig a hole approximately twice as deep and 3 times as wide as the plant, if your soil is heavy mix in general-purpose compost, horticultural sand and stone or potting grit to ensure good drainage. Gently compact the soil around the plant and water thoroughly.
Feeding and aftercare: When feeding use a liquid feed high in potash so it gets to the roots of the plant allowing them to absorb the feed.

How to grow
How To Grow Perennials
Seedlings & Plug Plants Once your seedlings or plug plants have been delivered, remove them immediately from their packaging. Place them in a shallow dish of water for a few minutes to soak the plug of compost. Ideally, these should be potted on immediately or if not, within a day or 2, keeping the plugs indoors in a warm and sunny place and ensuring the compost plug does not dry out. You may need to turn the plugs around as they will start to grow towards the light. Potting on Plugs:
When you are ready to pot the plugs on, lift them by their leaves, not the stem, as these bruise easily and can cause disease to enter and kill the plants. Pot into 9cm pots filled with potting on compost by making a hole big enough for the plug to go into. Plant so the seedling leaves are still proud of the surface. Tap to settle the compost and give them a good water.
Hardening off: Once your potted on plants reach approx 15cm (6in) tall and they are ready to plant out in their final location, the first step is to harden them off before moving them outdoors permanently. This involves simply placing them outdoors during the day and back undercover at night to allow them to get accustomed to the lower temperatures. Once they have been hardened off for a week your plants should be ready to plant out in their final location. Final planting of seedlings & plugs: Once the final frosts have passed, your plugs can now be planted in their final position. Choose decorative patio pots or in the garden borders. Best to use peat free compost or general-purpose compost. Water your compost before planting. Make a hole the size of your pot and plant up to the same level as the original pot. Water again to settle the compost around the root ball.
Bare Root Perennials
Soak the roots in a bucket of cold water for around an hour before planting to help hydrate the plant.
Dig a hole that is deep and wide enough to take the entire root mass. Place the plant in the hole and spread the roots out; the main stem should sit just above the surface of the soil. Fill the hole with soil and firm around the stem of the plant with your hand, or you can use your foot for larger perennials. Give them a good watering.
Garden Ready Plants and larger planting instructions:
Perennials in sizes Garden Ready Plants, 9cm, 1L, and larger, unpack and if the weather is favourable, put outside as soon as it arrives and give it a water.
When ready to plant, ensure it’s positioned in the right location and aspect in the garden.
Keep the area around it clear to avoid overcrowding which reduces its establishment and growth.
Dig a hole approximately twice as deep and 3 times as wide as the plant’s rootball. If your soil is heavy, mix in a soil improver before backfilling. We also recommend adding plant feed into the hole before back filling to help establishment and growth.
Place the plant in the hole so that it sits at the same level in the ground as it did in the pot. Firm the soil around the plant and water thoroughly.
Feeding and aftercare: Keep it well watered and fed for establishment and growth. Can be mulched in autumn/spring each year.
Planting and Flowering Months:
Planting and flowering months are subject to seasonal weather conditions. Recommended planting months for each variety are displayed on each product page. Large perennials over 9cm can be planted for almost all months of the year but take extra care during the cold winter months to avoid frost and hot summer months with extra watering.
