Gardeners' Notes:

Positive Tarragon13 On May 22, 2012, Tarragon13 from Beverly, MA wrote:

In 2007 I ordered three (3) 'Boone' glads from Old House Gardens. Hardiness was listed as zones 6(5?). This wild gladiola gave me only foliage and no flowers for 2 years. But, in 2010 one stalk had lovely soft apricot flowers. In 2011, three stalks had flowers. Now (in May 2012) new growth has popped through the soil and I'm looking forward to more flowers this season. And, I ordered three more bulbs from Old House Gardens to round out the clump. 'Boone' (c.1920?) is an unusual gladiola, but growers need to be patient waiting for stalks to flower.

This beautiful flower is popular in our garden even with visitors who think they don't like glads. Its relatively small size and wildflowery air help it fit into a perennial border better than the large florist's gladiolus can. Of course it's not hardy in northern Michigan, where I garden, but it reproduced itself freely, so I have many small corms stored for this year, as well as some larger ones. Recommended.
