Violet Riot Salvia: Dense Violet Spires That Mirror Lavender
Save
Violet Riot salvia covers itself in vivid violet-blue flowers held in deep purple calyxes, packed tightly along spikes 5 to 7 inches long. Compared with older salvias, it has a denser, neater habit and a more concentrated display, so the clump looks like a solid dome of violet spires at peak.
Despite the name, it is a well-behaved plant. The riot is all in the color.

Growing it with lavender
If you can grow lavender, you can grow Violet Riot. The two want the same full sun, the same lean, well-drained soil and the same light hand with water once established. That makes it one of the few companions you can mix directly into a lavender planting rather than giving it a bed of its own.
At about 22 inches tall and a little wider, it is close in size to many English lavenders, so it works in alternating groups along a border or as a second row just in front. Its deeper, bluer violet sits next to lavender's purple like a darker shade from the same paint chip, and it opens in late May, ahead of the lavender, then returns after shearing. Experiment with the mix in the Companion Plant Planner.
A design idea: the purple gradient
Try planting from front to back in a gradient: low creeping phlox at the edge, Violet Riot in the middle, lavender behind and something taller and paler at the back. You get layers of purple from spring through summer with very little upkeep, and the bees will work every layer.
Care notes
- Water: regularly the first season, then rarely. It is very heat and drought tolerant once settled.
- Shearing: after the first flush fades, cut back by about a third for a second flush.
- Air flow: crowded plantings in muggy weather can get powdery mildew after the first bloom; shearing and spacing help.
- Winter: wet, heavy soil is the main cause of loss. Leave stems standing or cut back in fall, and tidy up in spring.
Containers
The rounded clump stays tidy all season, so it works in a large patio container as well as in the ground. Use a gritty, fast-draining mix and a pot with a drainage hole, as you would for lavender.
Formats offered
Violet Riot comes as a full 72-cell plug tray for growers and mass plantings, and as a bare root plant for home borders. See each product page for current availability.
Frequently asked questions
Is it a culinary sage?
No. It is an ornamental salvia, grown for flowers. The leaves smell mildly herbal when brushed but are not for cooking.
Will it bloom more than once?
Yes, with shearing. Expect a strong first flush in late spring and another round after you cut it back.
