The color "Cyber Lime" is poised to make a bold and fashionable statement in the year ahead, positioning itself as a vibrant and on-trend choice for 2024. Incorporating a prominent plant color into garden spaces can undoubtedly infuse a sense of refreshment and contemporary aesthetics. We offer an extensive assortment of plants available, to the various tastes of individuals seeking to elevate the visual attraction of their outdoor spaces.



The Hosta 'Sum & Substance' is an award-winning plant known for its impressive size and distinct appearance. A standout in the garden, this perennial offers both aesthetic appeal and is relatively easy to care for, making it a favorite among garden enthusiasts.

Hosta 'Sum & Substance' is a remarkable and robust variety that can be a centerpiece in any shade garden. With its enormous, attractive leaves and striking lavender blooms, it's an asset to any garden. Following the care guidelines will ensure your Hosta remains vibrant and healthy for years to come.


  • Leaf Color: This variety showcases gigantic, heart-shaped leaves that boast a chartreuse color, eventually maturing to a deep glossy golden cast as the season progresses. The leaves are thick, which gives them a unique texture and also makes them more slug-resistant than many other Hosta varieties.

  • Bloom Color: In late summer, the Hosta 'Sum & Substance' produces tall stalks topped with lavender, bell-shaped flowers, providing a delightful contrast to the bold foliage.

  • Height & Width: The plant can grow to an impressive 30 inches in height with a spread of up to 60 inches, making it one of the largest Hosta varieties available.

General Care for Hosta 'Sum & Substance':

  1. Planting Tips:

  • Location: This Hosta thrives in partial to full shade. While it can tolerate some morning sun, shield it from harsh afternoon rays to prevent leaf scorch.
  • Soil: It prefers well-draining soil, rich in organic matter. Before planting, you can enhance your soil with compost or aged manure.
  • Spacing: Given its large size, space plants at least 4-5 feet apart to allow for mature growth.
  1. Watering:

  • Keep the soil consistently moist, especially during dry spells. Hostas prefer regular watering but are somewhat drought tolerant once established. 
  1. Mulching:

  • Apply a 2-3 inch layer of organic mulch around the base of the plant. This will help retain moisture, regulate soil temperature, and suppress weeds.
  1. Pruning:

  • While Hostas require minimal pruning, you can remove spent flower stalks after blooming to maintain a tidy appearance.
  • If leaves show signs of damage or disease, trim them off to maintain plant health.
  1. Fertilizing Guidelines:

  • Use HI-COTE 360 timed release fertilizer in the spring and for all your fertilizing needs. HI-COTE 360 can last up to 360 days on constant feeding, depending on your growing zone and weather conditions. We use HI-COTE 360 every day in our nursery production to keep our plant happy and healthy. Click here for more information and purchases – HI-COTE 360
  •  Alternatively, top-dressing with compost annually can provide necessary nutrients.

 Companion Plants:

  • Autumn Ferns: Create a textural contrast with the feathery fronds of autumn ferns.
  • Sun King Aralia: The golden foliage of sun king aralia complements the blue-green leaves of 'Blue Angel'.
  • Camellias: Pair with camellias for a beautiful combination of glossy evergreen leaves and elegant blooms.
  • Nandina Firepower: The vibrant foliage of Nandina 'Firepower' adds a pop of color to the shade garden.
  • Philodendron Xanadu: The lush, tropical appearance of philodendron Xanadu creates an interesting visual contrast with Hostsa.

Create an enchanting shade garden with Hosta sieboldiana 'Blue Angel' as the focal point, surrounded by its compatible companions for a harmonious and visually appealing landscape.
