Lobelia siphilitica

Majestic spires of rich sky blue make Lobelia siphilitica a prince amongst Lobelias.
No wonder it is also called the “Great Blue Lobelia”, because that just about says it all.
Large, rich blue blooms, stacked up on tall, upright stems in summer & autumn, do indeed make it great.

Lobelia siphilitica does best in Part Shade or Dappled Shade to Morning Sun, in normal garden soil, with average normal garden watering.
But it also suits wet, clay or boggy soils, and is truly spectacular planted at the side of a dam.
And then it can tolerate much more sun, if it has wet feet.

It is also frost hardy and low maintenance.
So the only work to be found is to shear back the spent flower stems at the end of each flush of flowers.
And you cut them right back to the socks when the season is finished. Then this encourages the low carpet of foliage to thicken up ready for next blooming.

Perennial clump. 75cm H x 30cm W. 


Sow in punnets indoors at any time. But spring or autumn is best.
