Can an evergreen be a perennial?
But, somewhat surprisingly, many “evergreen perennials” retain their foliage over winter. Of course, the extent to which perennials remain evergreen may vary from year to year, depending on winter weather conditions and their location in the garden; some may stay only semi-evergreen during particularly harsh winters. Evergreen perennials will keep their foliage throughout the cold winter months – as opposed to herbaceous perennials, that die back in the autumn and winter. This brings many benefits. In the winter months, the foliage will bring continued interest to beds and borders.Evergreen perennials are distinct from herbaceous perennials in that they retain their foliage all-year round. In contrast, herbaceous perennials die back in the autumn and winter then re-grow from their root-stock in the spring.
What flower takes 7 years to bloom?
It takes seven to ten years for a single corpse flower to gather enough energy to begin its bloom cycle. The Garden began collecting titan arums in 2003, as part of a worldwide conservation effort to preserve the species. Titan-arum blooms are rare and unpredictable. Each plant takes seven years or more to store enough energy to bloom for the first time. NYBG received its first titan-arum from Sumatra in 1932. In May 1937, a flower bud appeared.
