My top two are Heliotrope and Sweet Peas.
I'm working on a presentation for the local hort society on seed starting techniques. I thought it would be fun to have a Fragrance theme and in addition to all the examples being a "fragrant plant", we are going to have a guest speaker talking about companion planting with fragrance. Attracting pollinators and deterring pests.
What's you top choices for scented plants from seed?
Which one's do you wintersow?
