Positive Ursula On Jan 7, 2007, Ursula from Santiago
Chile (Zone 9b) wrote:

This Chilean native species requires full sun exposure and very little watering, which makes it adequate for xeriscaping.

Propagation from seed: regular spring sowing using a mix of 1/3 sharp river sand, 1/3 regular garden soil and 1/3 compost. Sow on top of this mix and gently press the seeds against the compost without covering them. Keep the sowing pan barely moist and pick once the seedlings have 2 true leaves. Plants grown from seeds mature and bloom on the second year.

Being Lobelia excelsa a very tall plant, it can be used to disguise a shed or a fence.

Not appropriate for containers.

It is a huge showy rare perennial from Chile. 6' high and about as wide. Mine is already way over that, it is multibranched, and just started putting out new branches from the old! It has been blooming since early Spring, flowers in stages, when batch start to fade, above it comes another batch, Nice red and orange color, really easy to grow for me. It prefers rich soil, and good drainage.
