Sir Prize Avocado
Persea americana 'Sir Prize'
Pronunciation: PER-see-uh a-mer-ih-KAY-na
SKU #44395
This more prolific and cold-resistant grandchild of the popular Hass variety produces delicious, buttery avocados that mature up to two months earlier, from October to January. Dark green skin with lighter green stipules turns purplish-black as the fruit ripens after harvest. Self-fertile type-B flowers; planting a complementary variety such as Hass or Lamb Hass may increase fruit set and extend the harvest season. Tolerates mild frost when established. Grafted on Zutano root stock.
LIGHT: Full sun
WATER: Water when top 3 inches of soil is dry.
SIZE: Reaches 15-25 ft. tall, 15-18 ft. wide; easily kept smaller with pruning.

Be Inspired: How to Use this Plant
| Bloom Time | Spring |
|---|---|
| Deciduous/Evergreen | Evergreen |
| Special Features | Easy Care, Edible, Fast Growing |
| Growth Rate | Moderate |
| Landscape Use | Container, Privacy Screen, Accent, Hillside, Shade Tree |
| Flower Color | White |
| Foliage Color | Dark Green |
| Companion Plants | 'Sir Prize' hails from a University of California breeding program, the result of an open-pollinated cross with a Hass offspring 'HX48' as the maternal parent. From the new seedlings, this selection exhibited several distinguishing characteristics: Fruit appearance remarkably similar to Hass and more recognizable as "Hass-like" than any previous commercial avocado of its type, maturing on average 6-8 weeks earlier than 'Hass' with larger overall fruit size and smaller seed, and considerably larger at an earlier stage. Additionally, it possesses an upright habit, making it a candidate for high-density planting and its Mexican-type genes lend cold-resistance and suitability to inland valleys and regions otherwise unsuited for 'Hass', giving commercial growers in California's central San Joaquin valley the opportunity of growing a 'Hass'-type avocado that can be sold much earlier in the season. 'Sir-Prize' was first asexually reproduced on the South Coast Research and Education Center in June 1991. |
| Care Instructions | Provide unamended, well-drained soil, and a wind-sheltered site. Apply a thick layer of mulch to conserve moisture, avoiding the trunk. Water deeply and regularly during first growing season to establish an extensive root system; reduce frequency once established. Periodic leaf drop is normal; allow to remain as mulch. Apply a slow-release fertilizer in spring after flowering. |
