Shiro Japanese Plum
Shiro Japanese Plum
History: Shiro plums (translated from Japanese as 'white') were developed in California and introduced in 1899. They were bred by horticulturalist Luther Burbank who is renowned for his extensive experimentation with creating new plum varieties. Shiro plums are most commonly grown in the United States and Canada.
Why We Grow It: This early Japanese clingstone variety has yellow skin and flesh that is juicy and sweet. The fruit keeps longer than most plums, lasting two to four weeks, and the tree is known for its compact growth and heavy crops.

Shipping: Every year we ship thousands of trees across Canada (except BC due to CFIA regulations). We carefully bag roots in damp sawdust, then box them and send them out via courrier. CLICK HERE to see our shipping policy.
Pick-up: We also have thousands of trees picked up from our nursery each year. The pick-up options is free, though you must wait until you have been emailed a confirmation that your order is ready to pick up, which will have further information such as hours, locations, etc. We really appreciate if you can make an appointment to pick up, then we can be as organized as possible during our busy season.

Our grafted fruit trees are graded into three categories, and the size includes the rootstock:
- 50-80cm whip: may have some minor branching, this grade is like a "b-grade" size tree in industry standards; we include in this price category trees that are over 1m but have some scarring or mild crookedness.
- 1m+ whip: may have some minor branching, aka feathering. This is like a typical one-year whip in industry standards.
- 1m+ branched: these trees must be over a meter and have 3 or more branches 30cm or longer, as well as a central leader. They are essentially a two-year tree in industry standards.
- For stone fruits only - 1m+ whip/branched: We have combined these grades based on the way these trees grow and are grafted. Plums, apricots, cherries, and peaches naturally tend to grow more vigorously compared to apples and are more likely to form larger trees with more branches. However, we only chip bud them so they are a one-year old tree by industry standards. Apples and pears are partially bench grafted, and using the knip-boom method the grading becomes more complicated, hence the reason they are split into different grades.
Orders that are cancelled last minute due to size (being "to small"), will still incur the applicable cancellation fees if the trees are true to our grading standards as per the agreement of sale when the order was placed.
