Lathyrus ‘Winter Sunshine Rose’

Lathyrus 'Winter Sunshine Rose'

Trial: Annual

Year Trialed: 2008

Good Qualities:

Wonderful fragrance (2); Attractive pink color (4); ‘Winter Sunshine Rose’ was a prolific bloomer (3); Flowers continued throughout the season, every bouquet put in the retail shop sold immediately!; Out performed all other varieties, strong plants, long stems; As early as others in trial such as Mammoth Choice Mix.


Too short (3); stem length, number of flowers per stem, the fragrance was not as marked as ‘April in Paris’, ‘Watermelon’, or ‘Royal Wedding’ from Renee’s Garden Seeds, the other problem was not enough flowers per stem, I set a marketable stem of having at least 4 flowers or buds, the conditions (late spring and poor stand) were not the best for evaluating but I was disappointed, ‘Mammoth Rose’ doesn’t have any fragrance but has larger blooms and more of them, the others from Renee’s have incredible fragrance and longer stems, even in lousy conditions; Seemed slow to start flowering; Our plants start blooming in July, our customers only want sweet peas for early spring weddings; We experienced nearly 3 weeks of overcast weather right after they began to bloom and all buds blasted, I lost weeks of cutting; Lower production than Mammoth Choice Mix; Crop failure – only one seed of 100 germinated, only 3 feet away from other peas which germinated well, the one seed grew into a plant with nice blooms with long stems – unfortunately the one plant did not get much attention so no conclusion can be made except the few blooms indicate potential.

Similar Cultivars:

‘Mammoth Deep Rose’; ‘Sunshine Lavender’, which I grew also and they are both great.


I started seed in peat pots and planted along trellis, after planting in the ground it took about 2 months before they started flowering, once started they just kept coming, from late September on, the flowers shatter after a couple of days, but still had the fragrance – I should note that we had a much cooler spring and summer than normal, punctuated with a hot blast just after July 4th – 109 degrees with wind and low humidity that cause both plants and people to wilt, even so the sweet peas kept trucking; Second year of experimenting with this crop, no more; I plan on growing only the Sunshine series in my hoop next year, they are awesome!; Flower head 3 cm, pod 5 cm.


Use bulb food or high sugar floral solutions.
