Helichrysum italicum or curry plant is a tender perennial. Outdoors, it does best in U.S. zones 8 to 11. It can't tolerate a hard frost. It prefers soil that drains well, full sun and warm conditions. It's a perfect choice for intermittent drought prone areas or for a xeriscaped (low water) garden. If you have a spot behind a shed or garage that tends to reject your efforts to plant it out, curry plant may be a good choice there, too. It performs well in poor soil and isn't finicky about niceties like pH (although keeping things on the neutral side wouldn't hurt). Because it's such a good sport about water, it doesn't require mulching. It's also a natural pest repellent. Bugs tend to avoid it, and deer hate it.
Growing to a height of about 30 inches or so, curry plant looks like a cross between lavender and rosemary. It has soft, gray-green foliage and produces small yellow flowers. It may require staking, especially in a windy location or a spot that sees a lot of foot traffic like a tree lawn
