'Hot Lips'

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).

'Ian's Red'

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.

'Iolanthe'

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).
