Product Description
Tricyrtis f. 'Autumn Glow' (30)ct Flat
Common Name: Formosa Toad Lily
Impressive variegation is what sets this toad lily apart from older cultivars. Per Tony Avent, it boasts the widest yellow leaf margins of any variegated Tricyrtis he’s grown. Compared side by side with ‘Gilt Edge’, you’ll see that the overall plant size, habit, and flowers are nearly identical, but it is that light edge that really makes ‘Autumn Glow’ truly live up to its name.
Orchid-like, reddish purple to blue violet speckled blossoms appear from late summer into early fall in the north, midsummer in the south. An excellent perennial for adding late season color to the shade garden.
Tricrytis performs best in humus-rich, evenly moist soil in partial to full shade. It is very long-lived and easy to grow. It tends to be a late-riser, so don't worry if you don't see this plant coming up with other perennials in early spring. Your patience will be greatly rewarded. This species spreads to form wide clumps. Division is recommended every 3-4 years in spring to maintain vigor.

Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
