Container: Ships in a 3 Gallon nursery pot—transplant to a decorative pot with drainage.

Temperature: Keep above 55°F indoors to protect roots.

Overwintering: Trim lightly before bringing inside to keep manageable and promote compact growth.

Bloom Cycle: Purple flowers appear continuously from spring to frost.

Pruning: Cut back spent stems after bloom waves for tidier form and rebloom.

Propagation: Easily propagated by division or cuttings.

Pests: Generally pest-free; rarely troubled by insects.

This shop has the most fantastic, healthy, gorgeous plants. I am a repeat customer and have never been disappointed. In fact the plants have always exceeded my expectation and plants are often much larger than expected. Packaging is some of the most professional I've seen, with not one leaf damaged. I'll be back for more.
