正体不明の棗 Jujube cultivar unknown

 練馬の渋谷園芸で買った、名札落ちのナツメが、現在2度目の開花時期が進行中で幼果がどんどん着いています。最初の開花は苗を購入した当時に存在していた枝からのもの。その後、苗の頭頂部に新梢が沢山出て、それらが成長するとともに開花が始まりました。新梢から成る苗の上半分に栄養が集中的に消費されているかのようで、元々の枝から成る下半分は非常に貧相になりました。この↓写真では、下のほうに少し見えている部分が、元からある枝です。

When I saw this leftover jujube tree at a large nursery in Nerima 2 months ago, they could not tell me the cultivar name because they had lost its name tag.  Within a few weeks, the tree started its first flowering.  After that, new buds started to come out at the top of the tree.  The new buds grew into new branches, and the tree has been in the second flowering phase, which in turn is followed by young fruit setting.  Due to the robust growth of the new branches, it seems that most of the nutrition the tree gets is being directed to the top half of the tree, with the result that the original branches, the bottom half of the tree, are now looking left behind in the growing process (the branches peeping out near the root of the tree).

以下は、最後の実の写真以外、すべて新梢から成る上半分です。

The following photos are, with the exception of the very last one, all from the top half of the tree, consisting of new growth after purchasing this plant.

葉っぱが他の品種で見たことない大きな葉っぱで、月桂樹の葉に似ています。

The leaves are quite large, unlike any other cultivars', and they look more like the bay leaf.

これは今開花中の上半分の枝についた幼果のうちで最も大きいもの。

This is one of the largest fruits from the current flowering, on the top half of the plant.

これは下の元からある枝の実で、最初の開花から着果したもの。最近、肥大速度が緩慢になってきて、上の枝の幼果に追いつかれそうです。葉っぱがこんなに大きいのに実が小粒だったらどうしよう、などと今から不安になってきました。一体どんな味の実になることやら。

This fruit is from the first flowering and growing on the bottom half of the tree.  The pace of growth among these old ones has been slowing down, and the new ones might soon catch up with these.  I cannot believe that a jujube variety with such large leaves might produce small fruits.  I also wonder about the taste of the fruits when they are ripe.
