The “Plant of the Year” is often designated by various gardening and horticultural societies or organizations, and sometimes by individual countries, so there can be multiple plants receiving this title in a given year. One of the more recognized programs is the “Perennial Plant of the Year,” designated by the Perennial Plant Association (PPA) in the United States. However, there are also annuals, houseplants, and other categories awarded by different organizations.

Here are the perennial plants of the year as awarded by the PPA from 2010 to 2022, along with a brief description of each:

2010 – Baptisia australis (Blue False Indigo)

This hardy perennial features tall spikes of deep blue flowers in late spring to early summer. It’s drought-tolerant once established and adds a striking vertical element to the garden.

An ornamental grass that stands upright and features tall, slender blue-green leaves that turn golden yellow in fall.

2015 – Geranium ‘Biokovo’ (Biokovo Cranesbill)

This perennial blooms late in summer into fall, featuring pure white flowers on long, graceful stems and thrives in partially shaded areas.

2017 – Asclepias tuberosa (Butterfly Weed)

2018 – Allium ‘Millenium’ (Ornamental Onion)

This allium variety has attractive, grass-like foliage and produces rounded heads of rose-purple flowers in mid-to-late summer.

2019 – Stachys monieri ‘Hummelo’ (Betony)

Valued for its rose-lavender, spiky flowers, and mounding, low-maintenance habit. It’s attractive to pollinators and provides a bold color statement.

2020 – Aralia cordata ‘Sun King’ (Golden Japanese Spikenard)

A shade-loving perennial with golden-yellow foliage that provides a bold color contrast. Small white flowers in late summer are followed by deep purplish-black berries.

2021 – Calamintha nepeta subsp. nepeta (Lesser Calamint)

Offers tiny, white flowers throughout the summer and a gentle, minty fragrance. It’s a favorite of pollinators and a great filler for any sunny spot in the garden.

2022 – Schizachyrium

All cultivars of Schizachyrium were selected for 2022. The fall color of this medium-sized native grass makes it stand out.

2023 – Rudbeckia ‘American Gold Rush’

Because of its thinner and hairier leaves, this hybrid Rudbeckia is resistant to fungus even in rainy, humid environments.
