Primula Belarina 'Cobalt Blue' wonderfully intense, vivid blue, scented double flowers which have a dot of white on the end of each petal, making them look like they're sparkling. These bold primroses are naturally compact and have beautifully textured leaves in rosettes and are smothered in flowers between March and June. They will look fabulous wherever you plant them. They're great in pots, containers, beds or baskets, in partial shade or sun - they really are easy to grow and bring the spring garden to life with their cheerful colours. Perfectly hardy in the garden, they're perfect when combined with other perennials and underneath trees and shrubs where they'll flower for months, gradually forming large clumps that can be divided every few years to give you more plants. Supplied as 3 plug plants ready for potting on or planting out, growing to a height and spread of 20 cm (8 in).
< With its thin, flat texture, slate is a beautiful alternative to gravel, and this blue variety is one of the most popular colour choices! This completely natural, recycled, lime free Welsh slate changes colour from pale grey-blue to glossy blue and purple when it gets wet which creates a contemporary look wherever it's used in your garden. It looks fantastic as a top dressing for pots and planters both indoors and out, especially for architectural specimen plants, and will help to retain moisture and supress weeds too. It's also fish friendly, so it can be used in aquariums, ponds and water features without the danger of it altering the pH or anything leaching out that could upset the delicate balance of the water. These larger-size slate chippings are naturally roughly edged and graded to be about 40 mm long, with varying widths. They make a great colour and texture contrast when used as an edging for slabbed or decked patios and are also suitable for pathways, becoming wonderfully reflective in wet weather. Although the slate is prewashed and ready to use, we recommend that it is washed again before aquatic use. As a guide, one bag of slate will cover 50 cm² (20 in²) at a depth of 25 mm (1 in). Supplied as a 20 kg bag.
Campanula glomerata ?Blue Crown? is a perfect perennial for the front of the border, especially in partly shaded spots.
Scabious 'Butterfly Blue' is great in wildlife gardens because, as its name suggests, it attracts scores of butterflies and bees between July and October. These pollinators flock to the hardy perennial's lavender-blue blooms, which protrude on dainty stems above grey-green, lance shaped foliage. Scabiosa atropurpurea, which is sometimes called Pinchushion Flower or Sweet Scabious, grows best in sunny, cottage garden borders, but also makes an interesting cut flower. Height: 40cm (1'4). Spread: 40cm (1'4).
An all weather tolerant variety of Agapanthus which will produce large, colbolt blue blooms set against strap-shaped deep green from June to August. It's a superb architectural plant which is perfect for your containers and garden borders.
Ever wondered if there is an easier way to plant bulbs? These innovative pre-planted bulb trays prove that there is! Simply place the biodegradable cardboard tray into your container or border and cover with compost.
There's nothing finer than a large Agapanthus in full flower at the height of summer, creating an eruption of brilliant blue. It's the perfect plant for an ornate container and with a little care will last a lifetime. Even before the 1m flower stems appear the bright green strap life leaves are a lovely sight and heighten the expectation of the blooms to come from mid summer. Agapanthus do best when their roots are restricted so don't be tempted to pot into too large a container - just a little wider than the nursery pot they arrive in will be fine. Place in a sunny spot and enjoy this African native in your garden over summer!
