HerbDoc is growing an interesting chive:
Here’s a newly developed chive, developed by Cook’s Garden and only available by plants two years ago. Allium tuberosum ‘Cha-Cha’ is grown exactly like the purple headed variety. It’s extremely cold hardy and loves the sun. Because I was unsure if it would cross pollinate with the chive and garlic chive stands in my herb garden, I chose to plant them in a pot on the deck.
They have survived two cold winters in that pot, and this year a bunch of seedlings sprouted with them. It will be interesting to see if they mimic their parents at maturity since I noticed Burpee was offering the seeds for sale in the 2015 spring catalog.
‘Cha-Cha’ has an outstanding false inflorescence filled with mini green chive leaves. The entire plant is edible with a mild onion flavor. Try the “mini chives” in salads or as a garnish on other summer dishes. They can also add a touch of whimsy to flower arrangements when left on their stems.
Editor’s note: This is a very cool-looking plant.

Great name!

You’re so right, CJ! It enticed me to buy three of them when they were introduced. 🙂

Found ‘Cha Cha” chive on Burpee’s plant offerings, and subsequently did some research trying to find out what species of Allium it really is. Based on the hollow stems and leaves (round in cross section), it most certainly is not Allium tuberosum, the commonly cultivated “garlic chives” with white flowers (although not really a true chive, true chives are “Allium schoenoprasum”). Most likely this is a selection of Allium vineale, the Crow Garlic, an invasive non-native, considered a noxious weed in most US States. It is common for some Allium species to produce little “bulbils” in the flower head that sprout leaves, the bulbils dropping off and starting new plants (thus their invasive nature). The percentage of bulbils to flowers varies depending on selection, there can be both flowers and bulbils, other times all bulbils without any true flowers. I will order a plant or two from Burpee to verify my diagnosis.
