From understated alpines to the frothy blooms of lilac and azaleas, Tom\u2019s selection reflects the huge range of late-spring plants available to us. Angelica is the icing on the cake<\/p>\n\n
WORDS TOM COWARD | PHOTOGRAPHS JASON INGRAM<\/p>\n\n
Height and spread <\/strong>4m x 3m (size can be controlled by pruning). Origin <\/strong>Bred by Victor Lemoine in 1899, Nancy, France.<\/span> Conditions <\/strong>Happy on most soils and will thrive on chalk; flowers best in full sun but tolerates light shade. Hardiness <\/strong>RHS H6, USDA 5a-8b\u2020<\/sup> . Season of interest <\/strong>May.<\/p>\n\n
The common lilac, S. vulgaris, <\/em>is native in mountainous regions of Eastern Europe. It is a variable species that was highly hybridised in the 19th century, resulting in more than 500 named cultivars. <\/span>\u2018William Robinson\u2019, named after the garden writer who created the gardens at Gravetye Manor, has large panicles of double, pinkish-lilac flowers and exceptional scent. Prune straight after flowering by removing flowered wood.<\/p>\n\n

ANGELICA ARCHANGELICA<\/em><\/h4>\n\n
Height and spread <\/strong>2.5m x 1.5m. Origin <\/strong>Northern Europe. Conditions <\/strong>Grows well in all garden soils; full to part shade. Hardiness <\/strong>RHS H6, USDA 5a-7b. Season of interest <\/strong>May to June.<\/p>\n\n
A statuesque biennial that will self-seed freely through the borders. The first year it makes a handsome foliage plant with its giant, parsley-shaped leaves. These are easily transplanted in the autumn to flower in the right spot the following spring. Its height is very useful in the flower garden at this time of year, and its big, green, pompom flowers contrast well with the vertical accents of lupins. We remove ours as soon as they\u2019ve seeded, so the gap can be filled with late-season interest. The fresh, young leaves can be used in salads, and in the past stems were often crystallised for cake decorations.<\/p>\n\n

PSEUDO FUMARIA ALBA <\/em>SUBSP. ACAULIS <\/em><\/h4>\n\n
Height and spread <\/strong>30cm x 30cm. Origin <\/strong>Southeast Europe. Conditions <\/strong>Well-drained soil; full sun to deep shade. Hardiness <\/strong>RHS H5, USDA 5a-7b. Season of interest <\/strong>May to November.<\/p>\n\n
Also known as pale corydalis, this is a useful and pretty evergreen perennial. It was first given to me by a friend who has created and cared for countless London gardens where London plane trees can often create dry shade \u2013 a condition for which this plant is excellent. We have a large clump thriving and colonising under an ancient yew. In spring it bears dense clusters of white f lowers, tipped with bright yellow. These look good over a long season and brighten up the darkest corner of the garden, especially with their pale-green, year-round foliage.<\/p>\n\n

ERINUS ALPINUS<\/em><\/h4>\n\n
Height and spread <\/strong>5cm x 10cm. Origin <\/strong>Southern Europe. Conditions <\/strong>Free-draining soil; full sun, in cracks of walls and alpine troughs. Hardiness <\/strong>RHS H6. Season of interest <\/strong>April to May.<\/p>\n\n
Commonly known as the fairy foxglove, this is a beautiful little plant that we have managed to establish in the cracks of some dry-stone walls. Small rosettes of tiny leaves with short, leafy stems bear clusters of pretty, little, purplish-blue flowers throughout spring. We started ours from seed, which were grown on in plugs before being squeezed into the wall cracks. Not only have they established in such harsh conditions, they also appear to be seeding and spreading themselves about. With any luck, they will eventually cover the entire wall. AGM*.<\/p>\n\n
Height and spread <\/strong>1-1.5m x 30cm. Origin <\/strong>British Columbia, Washington, Oregon, California and parts of Nevada.<\/span> Conditions <\/strong>Prefers moist soil; full sun to part shade. Hardiness <\/strong>RHS H4, USDA 5a-9b. Season of interest <\/strong>April to May.<\/p>\n\n
A genus of bulbous plants from the asparagus family, comprising five species from North America and one from South America. In the Pacific North West they were an important food for native Americans; the bulbs having a sweet taste when roasted. This camassia has beautiful, star-shaped, dark-blue flowers on tall stems and is one of the earliest to flower. It works well among shrubs and in borders but is best in meadows. In the orchard it times perfectly with the apple blossom.<\/p>\n\n

EUPHORBIA CHARACIAS <\/em>SUBSP. WULFENII <\/em><\/h4>\n\n
Height and spread <\/strong>1.2m x 1.5m. Origin <\/strong>Eastern Mediterranean (southern France to Anatolia). Conditions <\/strong>Well-drained soil; full sun. Hardiness <\/strong>RHS H4, USDA 7a-10b. Season of interest <\/strong>March to May.<\/p>\n\n
This handsome euphorbia makes a dramatic feature from March until May, with its huge heads of lime-green flowers borne on long, stiff stems and attractive, blue-grey foliage. It is very effective in drifts among the shrubs above our flower garden, creating a wonderful backdrop to spring plantings. Originating from rocky scrub in the Mediterranean, it is very drought tolerant. Flowering stems should be cut back as soon as they have finished, taking exceptional care not to come into contact with the milky, toxic sap, which can cause nasty blisters.<\/p>\n\n
Height and spread <\/strong>1m x 1m. Origin <\/strong>Southeastern USA and northern Mexico. Conditions <\/strong>Most well-drained garden soils; full sun to part shade. Hardiness <\/strong>RHS H5, USDA 3a-9b. Season of interest <\/strong>Flowers May to June; autumn colour in October and November.<\/p>\n\n
This handsome border perennial looks beautiful when its first shoots emerge in late spring, almost like purple asparagus.<\/p>\n\n
These quickly develop into erect, leafy stems with willow-like foliage supporting abundant clusters of star-shaped, sky-blue flowers with white throats. It will flower for five to six weeks and is a good, tidy, fresh-green foliage plant throughout the season before turning golden-yellow in autumn. It also has good winter structure.<\/p>\n\n
Height and spread <\/strong>2m x 2.5m. Origin <\/strong>Bred by Koster and Co in the Netherlands. Conditions <\/strong>Humus-rich, acidic soil (ideally pH 4.5-6); full sun to part shade. Hardiness <\/strong>RHS H6, USDA 4a-9b. Season of interest <\/strong>May to June; good autumn colour in October.<\/p>\n\n
Azaleas are priceless for their colour, fragrance and variety, not to mention the spectacular autumn colour that many display. The hybrid azalea \u2018Irene Koster\u2019 is part of the Occidentale group (R. molle <\/em>x R. occidentale) <\/em>and has delicate, rose-pink flowers with a small yellow blotch, and exquisite perfume. It makes a beautiful combination underplanted with camassias. Mature specimens should be pruned by removing the oldest wood, to encourage regeneration. AGM.<\/p>\n\n

ENKIANTHUS CAMPANULATUS<\/em><\/h4>\n\n
Height and spread <\/strong>3.5m x 3.5m (large specimens can reach 5m). Origin <\/strong>Japan. Conditions <\/strong>Acid to neutral soil; sheltered full sun or part shade Hardiness <\/strong>RHS H5, USDA 4a-7b. Season of interest <\/strong>May or June.<\/p>\n\n
An upright, deciduous shrub native to woodland in Japan. When in flower it is a beautiful sight as the plant appears to drip with small, nodding, bell-shaped flowers, which are creamy-yellow, with pinkish veining. It will bloom for about three weeks, and is best grown in light shade; we have a lovely specimen under a large handkerchief tree, making a fantastic combination when they are both in full flower. Autumn colour can be variable; good forms have a noteworthy orange or red display. AGM.<\/p>\n\n

LIBERTIA IXIOIDES<\/em><\/h4>\n\n
Height and spread <\/strong>1m x 1m. Origin <\/strong>New Zealand. Conditions <\/strong>Well-drained soil; sheltered sunny spot. Hardiness <\/strong>RHS H3, USDA 7a-9b. Season of interest <\/strong>May to June.<\/p>\n\n
This is a beautiful and architectural evergreen perennial from the Iris <\/em>family that is native throughout New Zealand. Its ridged flower spikes are elegant in bud, before opening with three-lobed, pure-white flowers. These look especially lovely in the evenings when they float like moths. There are several named cultivars with gold or bronze variegation that are well worth growing. <\/span>I prefer the normal olive-green, spiky foliage, which can make an attractive clump at the front of the border. Dead brown leaves should be carefully removed at the start of spring.<\/span><\/p>\n\n

Close to the beautiful, rugged C\u00f4tes-d\u2019Armor, on Brittany\u2019s northern shore, Kerdalo <\/strong>is a garden that will steal your heart the moment you walk through the gate. The 35 acres of grounds were designed by Prince Peter Wolkonsky in 1965 with Italian and Chinese inspiration. Some wilder parts feel like lush, tropical jungle, thriving in the mild Breton climate, and the garden is packed with stunning specimen plants. After the death of Prince Wolkonsky, the garden was neglected until 1997 when his daughter, Isabelle Vaughan, moved in and revived it. In 2021, she sold the garden to shoe designer Christian Louboutin, who appointed Tangi Rabin as head gardener. Tangi started his career at Kerdalo and was mentored by Isabelle. Now he\u2019s returned, it will be exciting to see how the garden responds. 22220 Tr\u00e9darzec, Brittany, France. Tel +33 (0)6 84 17 52 26, lesjardinsdekerdalo.com<\/a><\/p>\n\n\n\n
