It's ti time! Ti plants, of the genus Cordyline, are most commonly grown has houseplants. Which is fine, but gee, they look great in the garden too. Once the weather warms up I usually make a trip down to Lowe's or Home Depot, grab a few cheap ti plants and use them to plug any holes in the border. They look even better when you enliven the color combos with some long-flowering tender perennials such as this duranta (Duranta 'Homerus Depotus').
