Australian Almond Variety – Maxima
Maxima is a highly spur bearing tree that is suited to planting in traditional or higher density orchards. The hull flares away from the shell in a ‘banana’ fashion and has a very large kernel that may be suited to markets where large size attracts premium pricing.

Maxima is a semi-hard shelled variety that has consistently out yielded Nonpareil by 20% over eight years of yield assessments. It has superior fruit characteristics with a semi-hard shell, fully sealed shell and very large, sweet tasting, lightly coloured kernel. Maxima’s two main outstanding qualities are its early precocity to crop on spur wood and its large kernel size, approximately 2 grams. The full enclosed shell seal provides protection against insect and bird damage, whilst the hull detaches easily at harvest. The growth habit is slightly spreading similar to Nonpareil but bears mostly on spur growth. Maxima can be used as a late pollinator for Nonpareil, replacing Carmel and Wood Colony. Maxima needs cross pollination to successfully bear fruit.
