Phillip Godsmark, 2001

Ryecroft Jan

Introduced in 2001, Ryecroft Jan is a crisp white formal decorative dahlia, blooms 2.5 to 4 inches on plants 48 to 60 inches tall, and very prolific.

Clean white with no yellow in it. Summer Dreams reads it as ivory white and Three Sprouts specifies crisp ivory with no yellow undertones, which is the distinction that matters in a white dahlia, since many of them run cream or green at the center.

Why people hunt it

Ryecroft Jan was introduced in 2001, and Gager Estate credits Phillip Godsmark of the United Kingdom, though that attribution rests on that single source; I Love Dahlias corroborates the year and says only that it came from a grower in the UK. I Love Dahlias also reports that it won 47 awards at dahlia society shows across North America in 2022 and earned a place on the Cream of the Crop list, a claim that again comes from one seller and is repeated here as theirs. The Ryecroft prefix belongs to a British line, and this is another variety where British and American classification traditions disagree: the ADS-style record files it formal decorative, while British listings and several growers call it a ball.

Growing notes, including the hard parts

Ryecroft Jan is a small white grown for volume, and the grower testimony is emphatic: Sunset View calls it one of the most prolific varieties they have encountered, and Three Sprouts rates it highly productive. A tidy white miniature that produces heavily is close to the most useful thing a mixed cut flower grower can plant, because white goes into everything. Blooms run 2.5 to 4 inches. Height is the badly unresolved field, with credible reports from about 3.3 feet on British listings up to 6.5 feet at Three Sprouts; the American cluster sits around 4 to 5 feet, which is what is recorded here, but plan to stake and be ready for a taller plant. Pinch at 12 inches. Sources also split on whether it starts early or midseason.
