Best Almond Tree Varieties and Pollination: Do You Need Two Trees?
Almond varieties compared: Nonpareil, Carmel, Monterey, Independence, All-in-One, Lauranne, Guara, Tuono and more, with self-fertility, bloom time and pollination with bees.
Choosing an almond variety comes down to two questions: is it self-fertile? and when does it bloom? Traditional varieties like Nonpareil need a different variety nearby and bees to carry pollen; modern self-fertile varieties fruit alone. In frost-prone areas, a late bloom date is worth more than any other trait.
Common Varieties
| Variety | Self-fertile? | Bloom | Notes |
|---|---|---|---|
| Nonpareil | No | Early-mid | California's main variety; soft shell, premium kernel |
| Carmel, Monterey, Butte, Padre | No | Mid | Common Nonpareil pollinizers |
| Independence | Yes | Mid | Self-fertile California variety, Nonpareil-like |
| All-in-One | Partly | Mid | Semi-dwarf garden tree, soft shell |
| Lauranne (Avijor) | Yes | Late | French; widely planted in Spain and hedgerows |
| Guara (Tuono type) | Yes | Mid-late | Hard shell, productive |
| Soleta, Belona | Yes | Late | Spanish, good kernels |
| Penta, Tardona | Yes | Very late | For frost-prone sites |
| Marcona | No | Early | Spanish gourmet almond, round kernel |
| Ferragnès / Ferraduel | No (pair together) | Late | Classic French pair |
| Tuono | Yes | Late | Italian, hard shell |
| Robijn, Ingrid | Yes | Mid | Peach-almond types for wet, cool gardens |
Best Choices for Home Gardens
- One tree only: All-in-One, Independence, Lauranne, Guara or Tuono.
- Cold or frosty site: Lauranne, Penta, Tardona or Ferragnès with Ferraduel.
- Wet climate: Robijn or Ingrid for better leaf-curl tolerance.
How Almond Pollination Works
Almond pollen is heavy and sticky; it moves by bees, not wind. Self-incompatible varieties need pollen from a different, compatible variety blooming at the same time. Orchards plant pollinizer rows (often every second or third row) and bring in about 5–6 beehives per hectare (2–2.5 per acre). Home gardeners rely on wild bees and bumblebees; a mild, dry week at bloom makes a big difference.
Soft Shell vs Hard Shell
Soft- and paper-shell almonds (Nonpareil, All-in-One) crack by hand and have a high kernel percentage, but birds and insects attack them more. Hard-shell almonds (Marcona, Guara, Tuono) are better protected and store longer.

Frequently Asked Questions
Do almond trees need a pollinator?
Most do. Self-fertile varieties like Independence, Lauranne, Guara and Tuono fruit without a second tree.
What is the best almond tree for a backyard?
A self-fertile, compact variety such as All-in-One or Independence; in frosty areas, a late bloomer like Lauranne.
Which almond variety blooms latest?
Penta and Tardona are among the latest-blooming varieties available.
Are some almonds bitter?
Yes. Bitter almonds contain amygdalin, which releases cyanide; trees grown from seed can produce bitter nuts, so taste carefully and do not eat bitter kernels.
