Q.Where To Buy Quality Allium Bulbs?
My sister took a interest in Allium flowers after I share some fabulous photos from NYC’s Central Park Conservatory Garden and other locations around the Central Park. She has a fabulous sunny Walk thru garden in her back yard and I’d like to set her up with what she needs for her birthday in July. I know it’s post season for planting. But would like to put in an order for quality, reputable bulbs to receive in or around Sept when they need to be planted. It’s pure ornamental. Would like large and medium sized in 2 or 3 color choices. Thank you in advance. Any book recommendations specific to Alliums,too?

We don't make vendor recommendations but there are plenty of reputable online nurseries that sell bulbs. Check out their customer feedback and also see if your local extension service will make some recommendations. Possibly friends or neighbors have purchased bulbs.
