Shipova Mt. Ash Hybrid Sorbus Sorbus x Pyrus

A unique hybrid of Mountain Ash and Pear, Shipova Mt. Ash Hybrid bears round, yellow-orange fruit, about the size of a large apricot. Quite delicious, the sweet, seedless fruit has a delicate, rose-like aroma. Shipova forms a pyramidal-shaped tree with attractive, grayish-green foliage. Shipova is self-fertile.

SHIPOVA is a unique cross between a pear( pyrus) and mountain ash(sorbus). These exotic trees produce clusters of pear-like fruit that have sugar sweet flesh and an unusual fruity taste reminiscent of pineapple and mango. Shipova trees stay smaller(10 ft) than most pear trees. We find that once tree is established or acclimatized that it will survive ZONE 3 winters down to -40 C. The fruit is very nutrient dense and thus very filling/satisfying when eaten Thought to be self fertile but we suggest pollinating with pear or Mt Ash for better cropping. The Shipova fruit is seedless but with cross-pollination there is a slight chance that a viable seed might form inside the fruit core. EUREKA if it does.... as you can then try to germinate the chance seed into a new variety of Shipova and you will be the first person to do so in a long while...we have been trying to find a viable seed for 15 yrs now and still no luck! ³⁸⁰

Sorbier d'amérique Sorbus americana

Pour utiliser comme porte-greffe de poirier. Les poires se greffent bien sur le sorbier commun que les oiseaux plantent pour nous. Il y a une astuce cependant... vous DEVEZ vous assurer qu'au moins un tiers des branches restent sous forme de frêne de montagne et pas plus des deux tiers sont des poires greffées à l'arbre. Encore une fois, la raison en est que la poire n'est pas très douée pour nourrir les racines du sorbier. ⁴⁸
Fruits (sorbes) rouges à orangés, brillants, crus à un goût amers à cause de leur forte teneur en tannin. Ils sont meilleurs après qu’ils aient subi un bon gel.
En Europe, beaucoup préfèrent la gelée de sorbes à la gelée de groseilles rouges. Puisqu’elle est légèrement amère, elle accompagne les rôtis d'agneau, la venaison et le lièvre. Son goût s’allie bien avec ceux des pommettes et des agrumes, marmelade et confitures. ³⁷²
Les Algonquins font une tisane fortifiante dont la recette est comme suit : faire bouillir, durant plusieurs heures, de menus rameaux de cormier et d'épinette blanche, des feuilles de thé des bois (Gaultheria), des fleurs de sureau blanc (Sambucus canadensis) et un peu de vin. C'est évidemment une tentative de réunir, en un élixir complexe, la quintessence des sucs bienfaisants de la terre. ³⁷³
Les fruits (sorbes ou cormes) sont comestibles et se mangent quand les gelées d'automne les ont rendus juteux. ³⁷⁴
Cueillis très tard, après les premiers gels, les fruits servent à fabriquer des gelées, des confitures et des marmelades. Les fruits sont antiscorbutiques, diurétiques et astringents. On les emploie comme source de vitamine C et contre la diarrhée et la dysenterie. On peut les conserver séchés ou en sirop. ³⁷⁵
The mountain ash flower grows in clusters of 9-15. The flowers are hermaphroditic, meaning that flowers possess both female sexual characteristics, and male sexual characteristics. This does technically mean that they are able to self-pollinate, but the tree seems to understand the dangers of that.
Male sexual characteristics will mature before female sexual characteristics in order to prevent self-pollination. This is because self-pollination reduces the gene flow, and a tree that is a self-pollinated tree will have no adaptive traits and may be more vulnerable than a tree that has multiple genes. ³⁸¹
The two most common species in North America are the American mountain-ash, S. americana and the showy mountain-ash, S. decora, both native to eastern North America. These three species all reach about 12 m (40 feet) and have the typical reddish-orange fruit we associate with mountain-ash. The European mountain-ash is not always easy to distinguish from the American species S. decora and S. americana but if you check the winter buds, you will see grey hairs along the margins of the bud scales. The winter buds of the American species are generally hairless, black and somewhat sticky. In the autumn, the fall foliage of S. aucuparia is rather bland while the American species are often more colourful, especially S. decora. ³⁸²
Both American mountain-ash (Sorbus americana) and European mountain-ash (sorbus aucuparia) are monoecious - ('one house' : Greek) as the flowers are 'perfect' (they have both male and femal structures). Even so, most plants benefit from cross pollination and indeed some plants - and even some cultivars within the same species - are self sterile due to either gametophytic or sporophytic lethal genes that prevent self pollination. ³⁸³
