No. 1 Tri Voss lemon – Poncirus × Ichang papeda

No. 1 Tri Voss is a collector's hybrid attributed to the German breeder Bernhard Voß, known for his citrus hardiness rankings. From Poncirus and the Ichang papeda it inherits exceptional cold resistance. Its bell-shaped flowers, lightly tinged with purple, return several times during the season.

• Parentage: Poncirus trifoliata × Ichang papeda (Citrus ichangensis)
• Hardiness: −15 to −18 °C
• Fruit: drop-shaped, 6 to 8 cm, yellow, very juicy, with real lemon juice; many seeds, zest of little interest
• Ripening: November
• Habit: very vigorous and fruitful, 3 to 4 m in open ground; two-lobed leaves like the Ichang papeda

In the garden

Like Poncirus: sun, well-drained soil and very little protection once established. Leave room for its vigour.

The plant you receive

You receive a young grafted tree about 40 cm tall above the pot, low-grafted onto a Poncirus trifoliata rootstock from our own production. Planted young, it roots straight into your garden soil and establishes better than a tree kept in a pot for years.

Because it is grafted low, the variety itself forms the trunk: the tree stands on its own without a stake and can regrow from above the graft after a severe frost. All our citrus trees are grown at 1,000 m altitude in the Livradois, never in a heated greenhouse, with organic fertiliser only.

Grafted trees are shipped from June; the rest of the year, you can pre-order them.
