SPRING VETCHLING Lathyrus vernus 'Heavenly Blue'
This perennial is relatively easy to grow in partly shaded areas. Clump forming plant with a brilliant blue flower that blooms in early Spring (April-May). It prefers damp areas and may go into dormancy during summer droughts, though it should come back every Spring. We have successfully grown these plants in zone 4 and they formed nice clumps that stayed fresh all summer.
Type: Hardy perennial
Hardiness Zones: 3-7
Location: Part shade
Seeds per pack: 5
Germination: As with many perennials, these seeds require a period of moist cold to help them grow. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds on the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
