The development of the classification of hybrid hippeastrum began in 1934. Traub proposed a classification in which hybrids were divided into 9 categories. Namely:

1. Species. All cultivated hippeastrum species, such as Hippeastrum striatum, Hippeastrum psittacinum, Amaryllis immmaculata, etc., were assigned to this category.

2. Long Trumpet. Hybrids with tubular and long-tubular flowers were assigned to this category. The flowers are beautiful, elegant, usually fragrant, long-flowering. Pedicels are relatively long, slightly drooping; the perianth tube is 11-15 cm long.

Most of the hybrids in this category were bred by crossing the tubular-shaped hippeastrum species such as Hippeastrum doraniae, Hippeastrum elegans, Hippeastrum parodii, etc.

3. Belladonna type hybrids. This category included hybrids similar in flower shape to Amarillis belladonna L., Hippeastrum equestre, Hippeastrum striatum.

Perianth tube length is shorter than that of tubular hybrids. Pedicels are relatively long, the shape of the flower is varied, sometimes drooping.

4. Reginae type hybrids. This category included hybrids close in flower shape to Hippeastrum Reginae or Hippeastrum correiense.

The perianth tube is short. The perianth is horizontal or drooping, or erect, funnel-shaped, 10-14 cm long. Pedicels are shorter than those of tubular or Belladonna hybrids.

Depending on the overlap of the petals, two subcategories were identified:

4a - The petals overlap each other by more than 75% of the petal length. Petals with rounded, rarely pointed tips.

4b - The petals overlap less than 75% of the petal length. Petals with rounded, sometimes pointed tips.

5. Leopoldii hybrids. This category included large-flowered hybrids close in flower shape to Hippeastrum leopoldii Dombr. and to Hippeastrum pardinum.

The perianth is wide open, often flattened, horizontal, funnel-shaped, no more than 10 cm long. The perianth tube is short, about 1 cm.

Depending on the overlap of the petals, two subcategories were identified:

5a - The petals overlap each other by more than 75% of the petal length. The tips of the petals are rounded.

5b - The petals overlap each other by less than 75% of the petal length. The tips of the petals are rounded or slightly pointed.

6. Orchid flowering types. Hybrids with orchid-like flowers were assigned to this category. Most of the hybrids in this category have been bred by crossing hippeastrum species such as Hippeastrum papilio, Hippeastrum calyptratum, Hippeastrum cybister, etc.

7. Doubles. Hybrids with double and semi-double flowers were assigned to this category.

8. Miniature Amaryllis hybrids. This category includes miniature / small-flowered hybrids with a flower diameter less than 12 cm.

9. Unclassified hybrids. This category included hybrids that were not included in the other categories. This classification was adopted by the American Amaryllis Society.

But they were engaged in hybridization not only in America, but also in Holland, South Africa, and Japan. And in each of these countries, their additions were made to the main classification. These additions were mainly related to flower size and flower shape.

By flower size, according to the Dutch classification, hybrid hippeastrum were divided into: large-flowered, medium-flowered, small-flowered (see table).

In the South African classification, musical terminology was used, based on the size of the flower, the following division was obtained: symphony, sonata, sonatini and solo (see table).

According to the Japanese classification, hybrid hippeastrum were divided into: large-flowered, mid-flowered, miniature, subminiature (see table).

Flower diameter Dutch South African Japanese
more than 16 cm large-flowered (Large) symphony large-flowered (Large)
15 cm - - mid-flowered (Medium)
12-16 cm mid-flowered (Midi or Medium) - -
10-16 cm - sonata -
10-12 cm small-flowered (Small) miniature (Mini)
6-10 cm - Sonatini -
6 cm - - subminiature Super Mini
less than 6 cm - Solo -

According to the shape of the flower, they were divided into simple (non-double) and double. A simple flower has 6 perianth petals. Terry petals have more than 9. Depending on the number of petals, terry ones were divided into: semi-double “semidouble” (9-11 petals), terry, “double” (12-17 petals), extra-double “superdouble” (more than 18 petals).

If the flower is simple, then according to the classification, only the size is indicated, and if the flower is terry, then the designation "double" (double) is added to the size. For example, Aphrodite - Large Double, terry large-flowered; Jewel - Midi, Semi-Double, mid-flowered, semi-double; Razzmatazz - Symphony Semi-Double, Symphony semi-double; Benfica - Large-flowering, large-flowered, etc.

Hybrids with a tubular flower shape, with orchid-like flowers and sibistra were also assigned to separate categories.

To date, the following classification has been adopted in Dutch trading companies:

  • Group 1: Galaxy Group (large-flowered)
  • Group 2: Diamond Group (mid-flowered)
  • Group 3: Colibri Group (small-flowered)
  • Group 4: Double Galaxy Group (terry, large-flowered)
  • Group 5: Double Diamond Group (double, medium-flowered)
  • Group 6: Double Colibri Group (terry, small-flowered)
  • Group 7: Spider Group (sibistra)
  • Group 8: Butterfly Group (with orchid-like flowers)
  • Group 9: Trumpet Group (tubular hybrids).
