“Begonia × tuberhybrida”的意思、由来-开放百科全书

One of the first hybrids produced was B. x sedenii in 1870, a cross between B. boliviensis, collected by botanist Richard Pearce and a species from the Andes.^[5]^[6] Another species from Peru, B. davisii (named after Walter Davis), was also used in early breeding.^[6]

Nomenclature

1. (S) Single—large single flowers, 4 usually flat tepals (flower part undistinguishable as sepal or petal)

2. (Fr) Frilled, Crispa—large single flowers, tepal margins frilled or ruffled

3. (Cr) Cristata, Crested—large single flowers, frilled or tufted center of tepals.

4. (N) Narcissiflora, Daffodil-flowered—large more or less double flowers, central tepals form "trumpet"

5. (C) Camellia, Camelliflora—large double flowers resembling camellias, unruffled, solid colors

8. (Car) Carnation, Fimbriata Plena—large double carnation-like flowers, tepals fringed on margins

9. (P) Picotee—large usually double flowers like camellias, tepals with different color on margin blending with other color

10. (M) Marginata—like Picotee only distinct non-blending line of color on margins

11. (Mar) Marmorata, Marbled—like Camellia but rose-colored, blotched or spotted with white

12. (HB) Hanging Basket, Pendula—stems trailing or pendant, large to small flowers single or double

13. (Mul) Multiflora—low, bushy, compact plants with many small single or double flowers

Other systems confusingly use binomial nomenclature to refer to flower types, by the terms Begonia grandiflora, Begonia multiflora and Begonia pendula.

The last two correspond to groups 13 and 12 respectively. The first type, grandiflora (large flowered) is then subdivided by flower form, e.g. Begonia grandiflora erecta.^[8]

Cultivation

Tuberous begonias grow best in partial shade or filtered sunlight. Excessive exposure to sunlight can result in burnt flowers and leaves. However, too much shade will result in lush foliage and few flowers.
