Catmint is one of the toughest perennials you can grow. It's a proven performer during hot, dry weather, and the silvery foliage and blue flowers look great most of the season. Deadhead or cut back hard after first flush of bloom to encourage more flowers. Average, well-drained soil is usually sufficient. Tall types may need gentle staking; it sometimes seeds freely.
As you might guess from the common name, catmint is a favorite of cats. They'll often roll around in the plants in delight.

Perhaps the best-loved perennials, herbaceous peonies belong in almost every garden. Their sumptuous flowers -- single, semidouble, anemone centered or Japanese, and fully double -- in glorious shades of pinks and reds as well as white and yellow announce that spring has truly arrived. The handsome fingered foliage is usually dark green and remains good-looking all season long. Provide deep rich soil with plenty of humus to avoid dryness, and don't plant the crowns more than 2 inches beneath the surface. But these are hardly fussy plants. Where well suited to the climate, they can thrive on zero care.
These vigorous growers are beautiful additions to the garden. They vary from tall, stately plants suitable for borders to others that can be planted as creeping groundcovers. Flowers, too, vary from tight spikes of 1/2 inch to 1-inch cups carried alone or in whorls. Humus-rich, moisture-retentive soil is recommended; some varieties enjoy wet soil and ample water. Several sorts may become invasive and need to be corralled.Note: These are not the invasive purple loosestrife, which has been banned in many parts of the United States.
