Apples and people have a long history dating back approximetly 4000-10000 years and there are literally thousands of varieties and more being discovered all the time!! With so much information available its hard to know where to look. We’ve put together a few useful websites that you can visit for valuable info on taste, origins and pollination requirements of different types of apples.

Apples triploid (three‐set chromosome) apple varieties—commonly known for their vigor, large fruit, and resilience. Because triploids produce sterile pollen, they must be grown alongside compatible pollinators.

In New Zealand, apple varieties are grouped by their flowering time, from Group A (Early) to Group D (Late), where varieties within the same group, or adjacent groups (like A and B, B and C, C and D), can pollinate each other, with Group D overlapping the latest. Key pollinators like Gala, Golden Delicious, and Granny Smith are in different groups, meaning you must plant a variety from a compatible group to ensure fruit production.
A crab apple tree like Golden Hornet is a guaranteed pollinator for any apple variety.

Understanding Apple Pollination Groups in NZ

Group A (Early): Flowers first in the season.
Group B (Mid-Early): Flowers after Group A, with overlap.
Group C (Mid-Late): Flowers after Group B.
Group D (Late): Flowers last, overlapping with Group C.

Compatible Varieties

Group D (Late):
If planting an apple from this group, such as Gala, you need another apple in Group C or D for pollination.
Group C (Mid-Late):
Golden Delicious, a popular mid-flowering variety, can be pollinated by varieties in groups B, C, or D.
Triploid Apples:
Varieties like Egremont Russet are an exception; they have an extra set of chromosomes and require a partner that is not triploid.
