'Caerhays Belle'

M. sargentiana var. robusta × M. sprengeri 'Diva'

Awards
AGM

RHS Hardiness Rating: H5

USDA Hardiness Zone: 7-9

Flowers precocious, in March (S England), outfacing and cup-shaped to 30 cm across, salmon pink, deeper outside; tepals 12, heavy-textured, spoon-shaped with the tips of the inner ones curving upwards; fruit pink, to 20 cm long. A very floriferous small to medium tree which also fruits freely. From a deliberate cross by Charles Michael, Caerhays Castle, in 1951; the original at Caerhays measured 14 m × 404 cm in 2016 (The Tree Register 2022). Commended by Philippe de Spoelberch as a ‘most spectacular cultivar’ (pers. comm. 2021).


'Caerhays Splendour'

(M. sargentiana var. robusta × M. campbellii 'Lanarth') × M. campbellii 'Darjeeling'

RHS Hardiness Rating: H5

USDA Hardiness Zone: 7-9

Flowers precocious, mid-March in S England, cup-and-saucer shaped, a unique shade of vivid, deep pink. An upright, vigorous, small (potentially medium) tree selected at Caerhays Castle, Cornwall, registered in 2014 from a cross made in 2000 by Jaimie Parsons (Edwards & Marshall 2019). Williams, Gardiner & Gallagher (2016) highlight it as an up-and-coming cultivar in Europe.


'Caerhays Surprise'

M. campbellii Mollicomata Group × M. liliiflora 'Nigra'

Awards
AGM

RHS Hardiness Rating: H5

USDA Hardiness Zone: 6-9

Flowers precocious, 20–25 cm across, tending to face outwards on long, slender, arching shoots; tepals 9–12, narrow, deep purplish pink outside, paler inside. Long flowering, the last flowers appearing with the leaves. A small tree, tolerant of hotter summers than M. campbellii Mollicomata Group. From a deliberate cross made by Philip Tregunna at Caerhays Castle, Cornwall, 1959, and for too long underrated. Philippe de Spoelberch singles it out, noting ‘late, hardy, deep colour’ (pers. comm. 2021).


'Cairn Croft'

See Magnolia × thomsoniana ‘Cairn Croft’.


'Cameo'

(M. × soulangeana 'Sweet Simplicity') × M. 'Jurmag1'

RHS Hardiness Rating: H5

USDA Hardiness Zone: 6-9

Flowers precocious, tulip- to cup-shaped; tepals deep reddish-purple outside, blush inside, giving a bicoloured effect. A small tree selected by Vance Hooper, New Zealand before 2015, a sister seedling to ‘Cleopatra’; marketed internationally and protected by European plant breeder’s rights and US Plant Patent.


'Candy Cane'

RHS Hardiness Rating: H5

USDA Hardiness Zone: 7-9

Flowers precocious; 9 erect tepals, white with rose pink stripe running the full length, the colour more intense on inner whorls. Small to medium tree of uncertain parentage selected by John Allen Smith, from Todd Gresham’s hybrids at Gloster Arboretum, MS before 1994; starred by Philippe de Spoelberch, Belgium, as worthwhile (pers. comm. 2021).


'Carlos'

M. acuminata var. subcordata × M. denudata

RHS Hardiness Rating: H6

USDA Hardiness Zone: 6-9

Fragrant, erect flowers emerging just before and with the leaves (mid-April to early May, Belgium), rather frost resistant; inner tepals pale yellow, greenish at base, ~9 × 2.5 cm; outer tepals papery, greenish yellow. A small tree raised by August Kehr before 2003; grown at Arboretum Wespelaar and named by Philippe de Spoelberch for Belgian nurseryman Carlos Verhelst. However, de Spoelberch now singles it out for comment as ‘not the best yellow’ (pers. comm. 2021). Lobdell (2021) gives the pollen parent as M. × veitchii rather than its parent M. denudata.


'Cecil Nice'

M. denudata × probably M. sargentiana var. robusta

RHS Hardiness Rating: H6

USDA Hardiness Zone: 6-9

Flowers precocious, cup shaped; tepals 9, soft pink outside, white inside. An extremely floriferous medium tree, a seedling at Nymans of similar origin to the better known ‘Anne Rosse’, before 2000, named for a head gardener there. Philippe de Spoelberch finds it ‘very frost sensitive’ in N Belgium (pers. comm. 2021).


'Centennial'

See Magnolia stellata ‘Centennial’.


'Charisma'

M. 'J.C. Williams' × M. 'Vulcan'

RHS Hardiness Rating: H6

USDA Hardiness Zone: 6-9

Flowers precocious, cup-and-saucer-shaped, 20–30 cm across, deep rosy purple (redder than ‘J.C. Williams’). An upright to spreading, free-flowering small tree selected before 2018 by Ian Baldick, New Zealand before 2018 (Magnolia Grove 2022; Heerdegen & Eisenhut 2020). Highly regarded by Philippe de Spoelberch, Belgium (pers. comm. 2021).


'Charles Coates'

M. sieboldii × M. tripetala

Synonyms / alternative names
Magnolia coatesii hort.

RHS Hardiness Rating: H6

USDA Hardiness Zone: 6-8

Flowers with the leaves (May to June in S England), upfacing, to 18 cm across, fragrant; tepals creamy white, often crumpled; stamens crimson and conspicuous. Leaves generally resembling those of M. tripetala and clustered towards branch tips, broadly elliptic to 27 × 14 cm, papery with glaucous underside and a distinctive hairy midrib beneath. A large shrub or small (rarely medium) tree, with upright main stems and broadly spreading lateral branches. Full sun and dry air tend to scorch its young leaves; a sheltered site in light shade is ideal. A self-sown seedling which arose at RBG Kew around 1946, named for a propagator at Kew (Spongberg 1976). It was one of three apparent sister seedlings (Bean 1981; Treseder 1978): the others (perhaps inferior) were not named but material from one of them is believed to survive at Burncoose, Cornwall (The Tree Register 2022).


'Charles Dickens'

Synonyms / alternative names
Magnolia grandiflora 'Charles Dickens'

RHS Hardiness Rating: H5

USDA Hardiness Zone: 7-9

An evergreen variety often listed as a cultivar of M. grandiflora, with a broadly spreading crown, very large flowers to 15 cm across, and broad green leaves with a distinctive pale appearance on first opening, and a good indumentum. The bright red fruits are very large and persist 6–8 weeks. Introduced before 1965 by Jewel Templeton from the garden of one Charles Dickens, Franklin County, TN. Tetraploid (2n=76); probably a hybrid of M. grandiflora (Lobdell 2021), perhaps with M. macrophylla (Dawes Arboretum 2021). In England there is a fine specimen which fruits beautifully at Ventnor Botanic Garden, Isle of Wight (7.2 m × 44 cm in 2009), and several of similar size at RHS Garden Wisley (The Tree Register 2022); Philippe de Spoelberch also stars it as worthwhile from his Belgian perspective (pers. comm. 2021).

A rather narrow small tree raised from a cross between two M. acuminata × denudata hybrids by David Leach, Holden Arboretum, OH; registered 1997. Starred as worthwhile by Philippe de Spoelberch, Belgium (pers. comm. 2021).
