Seedlings Produced by Our Own Grower.
Out of the hundreds of seedlings we have watched blooming in our testing grounds for ten years or more, only four have reached the high standard of perfection which we have set as our ideal of really good peonies.
They have not been on the market long enough to be widely disseminated so that when the rating was made by the American Peony Society very few collectors had them in their gardens.
Dr. H. van der Tak (1916)—This variety shows up better each season and under the very unfavorable blooming conditions this year, it was remarkably beautiful. Early mid-season. Semi-rose type. Wine red sometimes showing a few stamens with a pronounced shade of crimson towards the center, while the edges of the petals are shaded somewhat lighter. A very vigorous grower, with stiff erect stems. Opens freely and for a red is a profuse bloomer. Each $5.00
