These are sold by the 'Eye' count. Also, 10 'Eyes' for $20. I have clumps with more than that in them that lets you start with a very mature plant!
Photos #1 & #2 show very mature plants and how color can appear depending on the light.
Photo #3 shows an individual 'Eye', Photos #4, #5, #6 show clumps of various sizes. The more 'Eye' the bigger the plant when they fill out. There are a few single 'Eye' plants in a 4" pot for $5 each or 3 for $12.
Pure white centers that stay white all season (rare for white hostas)
Wide, irregular golden‑to‑chartreuse streaks between center and margin
Dark green margins that frame the leaf
Medium size: typically 18–22" tall, 36–48" wide
Strong leaf substance for a variegated hosta
Lavender flowers in mid‑summer
Unlike many white hostas, Vulcan does not scorch easily in bright shade and does not revert to green.
Best in bright shade or morning sun + afternoon shade.
Handles more light than Fire & Ice or Patriot because the white center is thicker and less prone to burn.
Soil - Moist, rich, well‑drained soil with high organic matter.
Benefits from annual compost top‑dressing.
Slightly acidic to neutral pH is ideal.
Water - Needs consistent moisture, especially during spring leaf expansion.
Thick leaf substance helps resist slug damage, but even moisture reduces stress and keeps variegation crisp.
Fertility - Light spring feeding is enough.
Avoid high‑nitrogen fertilizers that can distort variegation or encourage floppy growth.
Seasonal Behavior in the Pacific Northwest:
Spring - Emerges mid‑April in Sequim‑area climates
White centers are bright and clean from day one.
Summer - Holds color well through heat spells if kept evenly moist.
White centers do not fade to cream (a common problem in other white hostas).
Fall - Foliage yellows and collapses cleanly.
Remove debris to reduce slug overwintering.
Winter - Fully hardy to Zone 3–4.
Divide every 4–5 years if needed.
Best time: early spring when eyes are just emerging.
Mature clumps typically have 8–12 eyes.
Vulcan maintains symmetry well and rarely produces off‑type divisions.
Strengths - One of the most stable white‑centered hostas
Strong contrast and season‑long color
Better sun tolerance than most white hostas
Good slug resistance for a variegated type
Excellent for structural planting in shade borders
Limitations:
Needs consistent moisture to prevent stress on the white centers
Growth rate is moderate, not fast
White centers can show hail or mechanical damage more visibly
Needs protection from hot afternoon sun in July–August
Typical annual 'Eye' increase for ‘Vulcan’:
• Moderate to fast multiplication: ~2–5 new eyes per year under good conditions
• Occasional jumps: 6–10+ eyes if the plant is well‑established, undivided, and in ideal soil moisture/light
• Slower the first 1–2 years after planting or division (normal for all hostas)
• Filtered light / bright shade (too much sun bleaches the white center)
• Consistent moisture — never let it dry out completely
• Rich, organic soil
• No division — leave it undisturbed for 3+ years
• Mulch in winter to protect the crown (recommended for hostas generally)
‘Vulcan’ is one of the best multipliers among white‑centered hostas, so if you’re tracking eye count year to year, you should see noticeable expansion once it’s established.
