I continue to report to you on plants that perform. I am quick to eliminate plants that don’t live up to expectations.Here are six topnotch perennials you will enjoy in your garden for many years.
Arkansas bluestar (Amsonia hubrichtii) grows into a 2-3 feet tall arching clump of soft, feathery green leaves. Blue starry flowers appear in late April into May (in Tennessee).

‘Gold Standard’ coreopsis (C. tripteris ‘Gold Standard’) is an unusually tall growing 5 – 7 feet high coreopsis. Starting in late July, multitudes of sunshine yellow flowers stand tall on sturdy wiry branches The bright floral display stands out over 2-3 months. ‘Gold Standard’ has a rhizomatous spreading habit, about 2 feet over 3 years.
