Sweet Pea 'Nimbus'
Lathyrus odoratus


Unique and popular color.

Bred By Unwins. From the Spencer Series. Gray-white petals with inky, blue-black streaks throughout and lining the petal edge. Plants produce 3–4, slightly ruffled blooms per 9–12" stem. Lightly fragrant.


Sweetpea Nimbus would have to be one of my top favourites and in my opinion is one of  the best flake varieties available. These stunningly attractive flowers have Inky grey blooms are deeply streaked and rimmed with dark eggplant colouring.



Life Cycle: hardy annual

Height: 6 to 8 ft

Site: full sun

Days to maturity: 75 to 90 days

Sowing: 1/2-1" deep

Plant spacing: 8 in

Pinch: when 4 to 6 in tall

Approxseeds per packet: 10


How to Grow:


Sow ½” deep in a 5” deep pot.

Use a good compost based seed starting mix. 

Keep at 50-55 degrees for germination.

Move to 35-50 degrees in full sun for bulking up (they dont mind low winter temperatures)

Transplant in early spring into rich soil in full sun. 


In mild areas seeds can be sown in pots in the fall, wintered over in a sheltered spot and planted out in spring. Everywhere else, sow seeds 10-12 weeks before the last frost and plant out right around the last frost.



When grown slow and cold, sweet peas will naturally branch on their own. If you see that your plant has not branched but is getting tall, you may take out the top set of leaves, provided you leave 2 or 3 sets on the plant. This will encourage robust side shoots. We never pinch as our plants almost always branch on their own. 





Cut stems that have at least two unopened flowers at the tip



Vase life: 


Harvesting flowers increases blooms. Vase Life: 4-6 days.
