These bright blue blossoms on 14-16" inch tall plants create a lovely border. Popular for its unique blue soft furry flowers, and long bloom time makes a nice counterpoint to the other colors in a bed.

The Best Ageratum

After Ageratum ‘Leilani Blue’ inexplicably disappeared from the trade anywhere, I’ve come to accept this is the best one available for planting in perennial borders. It’s the perfect mid-border filler and I’ve even used it up front. ‘Blue Horizon’ is too tall for me, except for a few places. It’s the one annual I wouldn’t want to garden without! Wish the seeds weren’t so expensive because I could easy use at least 80.

High Tide Blue Ageratum

All have germinated. Great luck last year. I put them in public gardens and they did very well with little care and dry conditions.
