Shamrock Iron Cross
Shamrock Iron Cross
Named for the unique cross pattern on the leaves, this gorgeous plant returns yearly to grateful gardeners and happy homeowners. Clusters of four green, heart-shaped leaves bear the deep maroon cross design and cradle small, pink, funnel-shaped blooms over a very long flowering period—from June to September! Versatile, too—Iron Cross works very well in decorative patio containers, along a walkway, or as a flowering ground cover. Attractive to pollinators and butterflies, as well as passersby, but deer won't bother it.

Attractive foliage and blooms all spring and summer
Very pleased with these. I used them mainly in boarders. I also used them in pots that had spring bulbs. Kept the pots looking good all summer after bulb foliage began to die.
Very strange growth pattern.
I planted them in pots. Just tall stems with pink flowers and not one green leaf has appeared. This is going to be very interesting to see what happens next.
Easy to grow, attractive foliage, beautiful pink flowers
This plant is a real gem! The smallest bag is 100 bulbs, so I was able to share these with a number of friends and everyone loves them!

- Asked by Flower Lady

What is the spread of the plant and any bug or mold issues ? Thanks
- Asked by Ken
- Verified Reply - AngelaThe Shamrock Iron Cross individual plants will have a mature spread of 3 to 6 inches. These are bulbs and you can plant many bulbs to create a mound.
