ROSE SEEDLINGS (バラの実生)

Last November, I harvested rose hips of Rosa 'Constance Spry' and 'Gertrude Jekyll' at the brick wall of our main garden, and took out seeds.  I measured the specific gravity of them throwing in water, and most of the seeds went to the bottom.  I sowed them in seed-starting containers on 3 November 2014.


(昨年の11月にレンガ塀のところのコンスタンス・スプライとガートルード・ジェキルのローズヒップを取ってきて、種を取り出しました。比重をはかるために水に入れると、ほとんどは水に沈みました。種を種まきポットにまいたのが昨年の11月3日でした。)


Left two hips from 'Constance Spry' and right one from 'Gertrude Jekyll'

Rose hips of 'Constance Spry' contained only a few seeds, and more seeds in 'Gertrude Jekyll' 

Most of seeds in water had sunk to the bottom.

Seeds ware planted in small pots.   
Some of seeds have germinated last month, and now the first true leaves appeared after the seed leaves (cotyledons).  It is said that they will bloom by the time the new rose seedlings are 6 to 8 inches tall.  Exceptions will be roses that had climbing roses as parents, as these may need to get a foot or more tall before they will bloom the first time.  Because parents of our seedlings are climbing roses, I must be patient for a bit long time to look at their flowers.


(先月、種のいくつかは発芽して、双葉のあと本葉も見えてきています。実生の苗が6から8インチぐらいに育ったら花をつけるといわれています。例外は親がツルバラの場合で、30cm以上に発育しないと花が咲かないようです。うちの苗の親はツルバラなので、花をみるまでは少し辛抱強く待つ必要がありそうです。)

  1. I've never tried growing roses from seed. I await the results with fascination.
