Top Hat Blueberry
Lowbush / Half-High · Zones 4–7 · Mid
Where to buy Plan its pollination partner
The original patio blueberry: a true dwarf that stays near a foot or two, covers itself in white spring flowers and small sweet berries, and turns red in fall. Crops are snack-sized, not pie-sized — grow it because a blueberry on the balcony is a delight, and plant a full-size bush too if you want volume.

Pollination
This variety is self-fertile, so one bush will fruit on its own — but a compatible second variety planted nearby reliably means more and larger berries, which is why nurseries and extension guides recommend planting in pairs or trios.
