Lobelia tupa


Add to wishlist Remove from wishlist
Amazing Chilean Lobelia that is perfectly hardy here if you mulch it during nasty cold snaps. This is one of those perennials that when you see it grown well and you aren't familiar with it, has an almost concussive visual impact. Even when you do know it well, it still seems like a freak of nature it is so beautiful.This gets multiple stalks to 7' high with spires of tubular red flowers for 6-8 weeks which beckon hummingbirds from afar. Highly dramatic and surprisingly easy given good drainage. This grows in sandy areas in Chile so drainage is key. We grow ours in raised beds and mulched with dairy manure as they have a healthy appetite. In late fall, we cut up the stalks and lay them over the crown and usually toss some more cow poo over that as we want to keep frost from the crown plus it can make growth early which can get frosted so the mulch helps. We get ours through short periods of low teens with no problem. This is surely one of the finest of the larger perennials.
