Hosta 'Undulata Albomarginata'
 

According to The Hostapedia by Mark Zilis (2009), "...most commonly planted white-margined hosta in the last 100 years."

This medium size (18 inches high by 36 inches wide) plant has pale lavender flowers with a mid-petal stripe in July. The flowers are sterile so they do not develop seeds.

Schmid (1991) changed the naming of this plant. Previously, it was known as a species by the name of Hosta undulata albo-marginata. As the current name implies, it has now been switched to cultivar status rather than a species. The most common reason for this switch is that there is no evidence that this plant exists now or has ever existed as a plant in the wild. In other words, it is a cultivated plant.

Zilis also points out the this plant was originally registered by The American Hosta Society as H. undulata 'Albo-marginata' in 1987. Other names that have been used for this plant in the past include 'Frank Sedgewick', 'Mackwoods No. 5', and Hosta japonica undulata aureo-marginata.

From the Field Guide to Hostas by Mark Zilis (2014), "...stands as the most widely used white-margined hosta in American landscapes in the twentieth century...looks great during April, May and June...deteriorates in July..."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Adaptable to many situations. Especially useful for covering large areas...Leaves less twisted and less undulate that those of H. 'Crispula', with which it is often confused."

It may have been sold at one time as Mackwoods No. 5.

An article about H. 'Undulata' and its origins by Bob Solberg in The Hosta Journal (1996 Vol. 27 No. 1) states that, "H. 'Undulata Albomarginata' is an interspecific hybrid of H. sieboldii x H. montana but of different individual parentage than H. 'Undulata'. It was probably sold to Thomas Hogg in 1875 in Yokohama, Japan. It is not a sport of H. 'Undulata' or H. 'Undulata Erromena', the white-edged sport of the latter being H. 'See Saw'...While the data presented here strongly support these conclusions, they do not provide absolute proof. DNA testing of these cultivars would prove very interesting."

 

"I am willing to bet just about every garden has this one. It may not be as showy as the others, but it is a landscaping workhorse. Extremely inexpensive and available everywhere for around $3.00, it can be bought in quantity and so can make an immediate statement in the garden. Wonderful for edging large lawns or walks through the woodland garden. At dusk its glowing white margins guide one around the place. This hybridogeneous speciod multiplies like wild fire."
