angelonia not germinating
All of my petunias germinated nicely but out of the four 6-pack cells of Angelonia (4 varieties), only 1 in 24 cells germinated. All I did was press the seeds gently in the soil per the instructions and put them under lights (the instructions said that light aids germination).
Am I not suppose to germinated these under a heat mat set to 80F? Or do they just take longer to germinate than my other annuals? I started them on Feb 22 (19 days ago). My current basement ambient air temp range is 62F-66F.
Other annuals/perennials that have successully germinated under the same exact conditions in my basement are Verbana, Agastache, Viola, and Osteospermum.
