Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

Pyrus communis ‘Léon Leclerc de Laval’

‘Fruit large, long-obovate, and rounding towards the eye. Skin smooth and shining, yellow, strewed with brown dots, and marked with tracings of russet. Eye large, with long, straight, narrow segments, set in a shallow basin. Stalk an inch and a half long, inserted without depression by the side of a fleshy lip. Flesh white, half-melting or crisp, juicy, sweet, and perfumed. An excellent stewing pear, which in some seasons is half-melting, and is in use from January till May and June.’ [Hogg – Fruit Manual p.197/1860].

Horticultural & Botanical History

I am unsure of its exact date of introduction as Pears of New York gives conflicting dates. ‘Van Mons raised a pear in 1816 which he dedicated to Léon Leclerc. The proper name of the latter pear is Léon Leclerc de Laval.’ [Pears of New York p.190].  ‘This, [Léon Leclerc de Laval] which is different from Léon Leclerc (Van Mons), was obtained at Louvain in 1825 by Van Mons.’ [Pears of New York p.446].

‘Léon Leclerc de Laval’ is figured in Album de Pomologie [ADP vol.1, pl.22/1847], the illustration used here.


History at Camden Park

Listed only in the 1857 catalogue in an Addendum as ‘Blanc perne’ [Pear no.51/1850]. ‘51. One of the very finest late pears.’ [Diary B, MP A2951/1862]. Obtained from Veitch’s Nursery, probably the original Exeter premises.

See also ‘Beurré Léon Leclerc’ and ‘Van Mons Léon Leclerc’.
