Until now the Hippeastrum Top Ten has not included a white and green cultivar. However, with the arrival of the ‘Challenger’ this could well be set to change.
A bicoloured Hippeastrum is often viewed as rather exclusive and this is true to some extent.
The Challenger has exceptionally large white flowers with their pale green centres. The flower diameter is no less than 21 cm. Other attractive features include the upright flowers, sturdy stems and the bud presentation in the box as well as a vase life of two weeks. In short, this is a quality product with stylish looks.
It is available from the Dutch auctions from October to the end of April. The term ‘Galaxy Grp’ is a collective name for all single flowered cultivars with a flower diameter of at least 16 cm.
Family
Hippeastrum is a member of the Amaryllidaceae family.

Hippeastrum and Amaryllis are often mentioned in the same breath, as though they are two names for the same genus. The flower commonly referred to as Amaryllis is in actual fact the Hippeastrum. True Amaryllis is a summer bulb plant reminiscent of a lily. Amaryllis was first found in the Cape Province in South Africa and there is only a single variety, i.e. Amaryllis belladonna. Since Amaryllis belladonna flowers before the leaves appear, its English name of 'naked lady' is quite appropriate. Hippeastrum is a winter plant from the tropical regions of South America, specifically the Andes mountain regions of Chile and Peru. The group consists of more than 75 varieties and belongs to the Amaryllidaceae (= Narcissus) family. The plants of this family grow in the region of South Africa that has winter rains, where they flower in early autumn (March/April) and produce leaves in winter (June/July). Hippeastrum and Amaryllis can easily be differentiated by looking at the stems: the stem of Amaryllis is solid while the stem of Hippeastrum is hollow. A further difference is that the seeds of Hippeastrum are black while those of Amaryllis are green. Hippeastrum produces flowers several times in a year while Amaryllis only flowers once.
Care tips:
• Slant cut the stems and stand in fresh water. It is advisable to cut a small piece off the stems every two days to achieve maximum vase life.
• Moving the flowers into a different vase or replacing the water in the vase will not impair their vase life.
• Do not forget that the hollow stems of Hippeastrum are filled with water. Drain them above the vase when moving them.
• When using Hippeastrum at an angle it is advisable to push a stick into the stem to prevent it from bending. It would normally take 10 to 14 days before this occurred.
• Hippeastrum grows taller as the flower opens. Ensure there is plenty of space above the flower ( 20 cm) to accommodate this growth.
• Hippeastrum does not need cut flower food but can tolerate it.
• Remove dead blooms to maintain the ornamental value.
