5 top garden designers recommend the best spring bulbs

Five leading garden designers recommend the best spring bulbs to plant in autumn to add colour into the garden after the dull winter months.

It may sound like a cliché, but spring bulbs really do add a touch of sparkle and much-needed colour when little else wants to show itself above the cold soil. Autumn is the best time to plant spring bulbs, because the soil is still warm. You can leave planting tulips until November and alliums until early December but the smaller, early bulbs need to be in by the end of September if you want them to flower in March. Plan ahead to makes sure you have the bulbs you want, in time for planting. Here you’ll find recommendations from leading garden designers of the best bulbs to plant in autumn, for spring flowering.

  3. Galanthus nivalis

    Galanthus nivalis, February, Suffolk

    I’ve lost count of how many of these sweet, pure-white narcissi I’ve planted. It is simply the best and most beautiful in my book – and very reliable too. Flowers in April. Height 30cm. Hardiness USDA 5a-11.

It’s easy to overlook bulbs, but they add another dimension that can bring some magic at a dreary time of year.

Alison’s favourite bulbs

  1. Tulipa ‘Bruine Wimpel’

    Raised border containing Tulip 'Malaika' and Wallflowers

    Sometimes sold as Tulipa Malaika, this is a subtle, single, late tulip, which fades from smoky-pink to rust. Looks good with the dark-red tones of Tulipa ‘Ronaldo’ and Anthriscus sylvestris ‘Ravenswing’. Flowers in April. Height 60cm. Hardiness USDA 3a-8b.

  2. Narcissus ‘Jenny’

    Narcissus 'Jenny'

    The graceful form and soft tones of this daffodil work well when naturalised in grass. It has creamy-white, swept-back petals with a pale-yellow trumpet. Height 30cm. Hardiness RHS H6, USDA 3a-8b.

  3. Allium nigrum

    Allium nigrum

    Flowering in early June, these give height and impact before many of the perennials get going. The off-white domed heads have a distinctive green centre in each of the many flowers. Height 75cm. Hardiness rating RHS H5, USDA 5a-9b.

  4. Muscari latifolium

    Muscari latifolium

    The two-tone flowers are strikingly unusual and look as though they have been dipped in violet sherbert. Flowering in March, they look good popping up through the black grass, Ophiopogon planiscapus ‘Nigrescens’. Height 20cm. Hardiness rating RHS H5, USDA 6a-9b.

  5. Fritillaria assyriaca

    Fritillaria uva-vulpis, syn. Fritillaria assyriaca

    Best planted in old terracotta pots so you can bring them indoors where the subtlety of the mahogany flowers, tipped with yellow ochre, and the elegant form of their linear leaves can be appreciated up close. Flowers in April. Height 30cm. Hardiness rating USDA 7a-9b.

  6. Narcissus ‘Segovia’

    Narcissus 'Segovia' growing in a pot at Mary Keen's garden, The Old Rectory

    This scented, miniature daffodil has pure-white petals with an unusual flat, lemon cup in March.  Plant some in a pot near your door and they will provide and air of zingy spring freshness every time you pass by. Height 25cm. Hardiness RHS H6, USDA 3a-9b.

Nigel’s favourite bulbs

  1. Narcissus ‘Petrel’

    Narcissus 'Petrel'

    I have fallen in love with pure-white narcissi in general, and now use them widely to illuminate shady places. N. ‘Petrel’, however is one of the best. It is relatively short, scented and extremely graceful. Flowers in April. Height 20cm. Hardiness ratings USDA 5a-11.

  2. Erythronium revolutum Johnsonii Group

    Erythronium revolutum johnsonii

    Beautiful, dramatic and uplifting wild plant communities from around the world inspire my plantings, and that is exactly the way I use bulbs – taking my guide from how they might grow in natural situations. In the wild, erythroniums form the most beautiful sheets of colour in woodlands – it’s the sort of pictorial effect that really gets me going. Many, such as this one, have superb mottled foliage too – great value. Height 15-25cm. Hardiness rating USDA 3a-9b.

  3. Tulipa turkestanica

    Tulipa turkestanica

    I use this extensively in dry-meadow plantings – I love the dainty, white, star-shaped flowers that are held by the tall main stem. It also has great seedheads and lovely glaucous foliage. Flowers from March. Height 25cm. Hardiness rating RHS H5, USDA 4a-8b.

  4. Allium stipitatum ‘Mount Everest’

    Allium 'Mount Everest'

    It’s not just the white globes, which appear in June, that do it for me – especially when they are planted en masse – but the rich-green seedheads that come after the flowers are also extremely ornamental. Height 1.2m. Hardiness USDA 3a-8b.

  5. Tulipa praestans ‘Fusilier’

    Tulipa praestans 'Fusilier' AGM - Tulip, April
     

    Another of my essential plants for steppe plantings: the multiple, bright-scarlet flowers make for a long-flowering display from March. I like the bold red and green combination of this among the new foliage of ornamental grasses. Height 15-30cm. Hardiness RHS H6, USDA 3a-8b.

  6. Fritillaria persica

    Fritillaria persica

    A sexy bulb. The upright form and dusky purple flowers that appear in April have it all. I like to use it in drifts of widely scattered individuals in dry-steppe or dry-meadow plantings. Height 1m. Hardiness rating RHS H4, USDA 5a-9b.

Bulbs are invaluable for injecting early season colour. The key is to think big and plant in generous quantities.

Declan’s favourite bulbs

  1. Nectaroscordum siculum

    Allium siculum syn. Nectaroscordum siculum

    Pendulous umbrellas of up to 30 drooping, bell-shaped, creamy-green flowers, each with purple and pink markings, are carried on stiff stems. As these fade, they turn upright to form spires of erect, shuttlecock-like seedheads. Flowers May to June. Height 80cm-1m. Hardiness rating RHS H5, USDA 6a-10b.

  2. Leucojum aestivum ‘Gravetye Giant’

    Leucojum 'Gravetye Giant'

    Fragrant, snow-white, bell-shaped flowers tipped with green.  I have planted it among ferns on the edge of a woodland garden and in borders with Narcissus ‘Thalia’ and Tulipa ‘Spring Green’ for a more sophisticated combination. Flowers April. Height 45-55cm. Hardiness RHS H7, USDA 6a-9b.

  3. Narcissus poeticus var. recurvus

    Narcissus poeticus var. recurvus

    Despite its delicate appearance, this deliciously fragrant, late-flowering, wild species with simple, pure-white petals surrounding small, red-rimmed, yellow cups, is tough and sturdy. Will increase gradually over time and lends itself to many planting styles. Flowers April to May. Height 40cm. Hardiness rating RHS H6, USDA 3a-9b.

  4. Tulipa ‘Ballerina’

    Tulipa 'Ballerina'

    The beautiful pointed petals of this scented, lily-flowered tulip add warmth to late spring plantings. Set it off against the acid-yellow of Euphorbia and plant with Tulipa ‘Burgundy’ for a sumptuous combination. Flowers early to mid May. Height 55cm. Hardiness rating RHS H6, USDA 4a-8b.

  5. Tulipa ‘Burgundy’

    Tulipa 'Burgundy'

    Rich, dark-purple, arched petals are carried on strong stems. The tight nature of the lily-flower varieties seems to help them withstand heavy rain more than other tulip cultivars. Perfect for cut-flower displays. Flowers early to mid May. Height 50cm.

  6. Narcissus ‘Rapture’

    Narcissus 'Rapture'

    The golden-yellow, long-lasting flowers of this little narcissus can’t fail to bring a smile to your face. I plant them en mass to naturalise in a lawn, or at the front of a border or in a window box. Flowers March. Height 25-30cm. Hardiness rating RHS H6, USDA 3a-8b.
