'Genoa' Lemon vs 'Eureka' Lemon – what is the difference?

While both 'Genoa' and 'Eureka' are popular lemon varieties, they do have some key differences. 'Genoa' tends to be a smaller tree overall, growing wider rather than tall, often reaching about 3 metres in height and width. 'Eureka' generally grows to a similar height (around 2-3 metres) but tends to be more upright in its growth habit. 'Genoa' is also considered more cold-tolerant than Eureka. In terms of fruit, 'Genoa' has a smooth, thin, bright yellow rind that can sometimes have a chartreuse-green tinge. 'Eureka' has a thin to medium-thick, bright yellow rind. Both are juicy and sharply acidic, typical of true lemons. 'Genoa' is often described as having 3-8 seeds, while 'Eureka' is often described as virtually seedless. Both have a strong, acidic lemon flavour. Some might perceive slight nuances, but generally, they are both considered "true" lemons with a classic tartness.

Lemon 'Eureka' vs 'Lisbon' – what is the difference?

While both 'Eureka' and 'Lisbon' are popular and widely grown lemon varieties, they have some distinct differences. In short, choose 'Eureka' if you prefer a potentially more consistent year-round producer in warmer areas and a tree with fewer thorns. Choose 'Lisbon' if you need a more cold-hardy tree with denser foliage and are less concerned about thorns, especially for young trees. 'Lisbon' is also known for its vigorous growth and potentially larger fruit. Both are excellent lemons for culinary uses and are widely grown in New Zealand.

When do 'Eureka' Lemon trees bloom?

'Eureka' Lemon trees in New Zealand typically bloom during spring and summer. They can produce some flowers sporadically throughout the year, but the most significant and noticeable bloom happens during the warmer months. This flowering period then leads to the main fruit harvest, which is typically in winter.
