Snake's Head Iris (Hermodactylus tuberosus)
Snake's Head Iris (Hermodactylus tuberosus)
Be on the lookout for this snake in the grass. Snake's Head Iris is a unique, winter hardy perennial that really charms with its exotic, vibrant green blooms accented by dark purple, nearly black falls. It is quite a looker in sunny borders where it can be admired up close, and makes a fantastic cut flower, too. The mid to late spring flowers have a subtle fragrance that intensifies in the warmer temperatures. A wonderful naturalizer that adds brilliance to rock gardens and woodland sites.

How does this work in central Florida with high heat and humidity?? I'm new to gardening here and discovering many zone 9 plants just fizzle in this summer
- Asked by Bobbi
- Verified Reply - AngelaIn zone 9, I would suggest a planting site that receives at least 4 to 6 hours of early sun and afternoon shade. Provide well draining soil but provide regular watering in the absence of rain.Was this answer helpful to you
- Q
I have read these go dormant in the heat. So, does one plant them like spring bulbs adjacent to other things that will fill in as these die back? Don't want a bunch of messy foliage after blooming, and can't find photos of the plant thru it's growing season.
- Asked by julia
- Verified Reply - AngelaHermodactylus tuberosus foliage does die back after blooming. The foliage is pretty narrow and not as noticeable as some other spring bloomers. You may still want to plant something to fill in or camouflage it.Was this answer helpful to you

Will these small Iris bloom the first year? It would be so helpful to know this with EVERY plant you sell.
- Asked by Joan P
- Verified Reply - AngelaThe Hermodactylus tuberosus (Snakes Head Iris) is likely to bloom the first year planted. The blooms get better and more abundant as they naturalize and mature. Was this answer helpful to you

How close together should I plant the snakes head irises in a pot? Same question for the Oxalis versicolor. Thanks!
- Asked by Lola
- Verified Reply - AngelaI would plant them no closer than 2 inches apart in a pot. That applies to both Snake's Head Iris and Oxalis Versicolor. Was this answer helpful to you
