Lobelia laxiflora.

Wow. I would never, in a 1000 yrs, have suspected Lobelia.

Thank you.

Fof

It’s a thug in the garden. Spreads with rhizomes and takes an extra two feet of radius each year. Lobelia tupa is much more interesting and spreads less.

Interesting.....I have had the opposite experience. L. tupa grows to an impressively massive size while L. laxiflora often fails to return after winter. No danger of it trying to take over :-)

How strange. It’s probably all about siting then. Perhaps ignore both tupa and laxiflora and go straight for the unequivocally amazing ones: Lobelia rhynchopetalum, deckenii, and telekii.
