Jargonelle and Buerre Hardy Pear Trees

[VirginVegGrower]

Does anyone know if these two will pollinate with just each other or do I need a n other variety and if so, which varieties? Thanks in advance.

Here you go...they are both there!)

Jargonelle is triploid, so is not a reliable pollinator of any pear tree.

Oh - and Jargonelle is a tip-bearer with a long, straggly habit and long internodes (i.e. less well-branched).
As a triploid, it also tends to be more resilient and more disease resistant than most. It has a reputation for growing where most others fail* - a common feature of many triploid apples and pears.
My experience is that Jargonelle - like the triploid apple Ashmead's Kernel - is somewhat more vigorous than the "medium vigour" attributed to it by "the books".

On pear** rootstock Jargonelle is likely to eventually become a very large and very long-lived tree. It is considered to be among the longest-lived pears, potentially living 200-300 years and attaining a phenomenal size by that age.


*
Pears on Quince A or C will not tolerate difficult conditions, so having a poor-soil-tolerant scion such as Jargonelle may not help much. Consider Pyrodwarf rootstock for difficult conditions - it copes much better than Quince-derived rootstocks in less-than-ideal conditions. Pyrodwarf is somewhere around MM111 equivalent vigour.

** Most pears on the commonly-available Quince A or Quince C tend to be relatively short-lived; the partial incompatibility between pear and quince which causes dwarfing also tending to result in a shorter lifespan and more risk of succumbing to disease or malnutrition.
