AGM
RHS Hardiness Rating: H5
USDA Hardiness Zone: 7-9
Flowers precocious, very fragrant, narrowly cup-shaped, delicate pink with lavender overtones, deeper towards the base. A floriferous upright, small to medium tree. One of the original Gresham hybrids, starred by Philippe de Spoelberch as worthwhile from his Belgian perspective (pers. comm. 2021).

M. acuminata 'Miss Honeybee' × M. 'Elizabeth'
Flowers with or just before the leaves, large; tepals 6–7, deep yellow, rather floppy. A strong tree with lightly twisted branches and large dark green leaves, selected by Philippe de Spoelberch at Arboretum Wespelaar before 2001, from a 1992 August Kehr cross (Arboretum Wespelaar 2021). The cultivar name reflects its parentage.

(M. × brooklynensis 'Woodsman') × M. 'Elizabeth'
RHS Hardiness Rating: H6
USDA Hardiness Zone: 5-8
Flowers with the new leaves, to 12.5 cm across, deep yellow with a pink basal flush on each narrow tepal. Upright, fast growing small tree selected by August Kehr, 1992 (Edwards & Marshall 2019).
M. campbellii Mollicomata Group × probably M. sprengeri var. diva
RHS Hardiness Rating: H6
USDA Hardiness Zone: 6-9
Flowers precocious (late March to early April, Belgium), 20 cm across; tepals 8, pink outside deepening to maroon at the base, inside white with a hint of pink. Leaves nearly oval, to 23 × 23 cm. A small, potentially medium tree bought from the Esveld nursery, The Netherlands, by Philippe de Spoelberch who recognised its hybridity, naming it in 1994 (Arboretum Wespelaar 2021). The ‘rich, voluptuous base’ of the tepals inspired the name (Callaway 1994).
M .× soulangeana 'Pickard's Ruby' × M. 'Vulcan'
RHS Hardiness Rating: H6
USDA Hardiness Zone: 5b-7
Flowers saucer shaped, to 20 cm across, before the leaves; tepals 12, clear red. Habit often shrubby. Buds more tender than ‘Vulcan’, and flower colour more variable (Edwards & Marshall 2019). Raised by Ian Baldick, New Zealand, before 2004; his ‘Red As’ has the same parentage.
M. × soulangeana 'Lennei' × M. 'Mark Jury'
RHS Hardiness Rating: H5
USDA Hardiness Zone: 6-9
Flowers precocious, from mid-March in S England, bowl-shaped, very large, to 28 cm across; tepals soft lavendar-pink outside, cream inside. A small tree flowering from an early age and over a prolonged period, buds being produced down the length of the branches. An early Felix Jury hybrid, introduced by Duncan & Davies, New Zealand, in the early 1970s. The more vigorous ‘Atlas’ shares this parentage (Jury 2017; Jury & Jury 2021). Highly rated by Philippe de Spoelberch, Belgium (pers. comm. 2021).
