The leaves can reach a size of up to 9 inches in size and 11 inches wide. In early to midsummer pale lavender flowers appear atop the mounding leaves.

Homeowner Growing Tips: Hostas grow best in moist, well drained soil with high organic content and slightly acidic to neutral pH. They prefer slightly sandy soil over heavy clays as they need aeration for the roots. Grow in high-filtered or dappled sunlight--they can tolerate morning sun but not hot afternoon sun. Hostas are prone to slugs and deer browsing, though some kinds with thicker foliage may not be damaged as badly. Apply slug bait in early spring before the leaves have unfurled to prevent damage. Divide large clumps, if necessary, in spring when sprouts appear, or late summer. Remove dead foliage from the garden in late to early winter.

    I am so happy with Romence plants! Diamond Lake is very big, in a big pot. Best place to order online, if they were closer to me I would purchase in person. Always healthy, robust plants, packed extremely well!!! Thank you.
