Silky Gold Tropical Milkweed

Asclepias curassavica 'Silky Gold'

An exotic yellow variety of tropical milkweed from South America. Large clusters of golden yellow flowers are displayed against yellow-green foliage. This easy care plant mixes beautifully with other tall perennials and is ideal for naturalized areas, meadows, and borders. Prune to the base in fall, especially if it does not go dormant naturally in your climate. This prevents Monarch butterflies from feeding at the wrong time of year. An herbaceous perennial.
