Arum maculatum

From: grsjr at juno.com (George R Stilwell, Jr.) on 1997.10.24 at 01:32:40(1482) Gene & Jan, Peter Boyce doesn't list an Arum maculata in his book, nor have I heard of it. Are you sure you don't mean Arum maculatum? I believe hort. latin demands "um" for Arum rather than "a". +More Peter describes 34 different forms, ssp., etc of A. maculatum. Pandora Sellars' beautiful colored illustration follows page 48 (Plate 1). Ray

From: "Peter Boyce" <P.Boyce at lion.rbgkew.org.uk> on 1997.10.24 at 13:38:33(1487) Dear Folks I saw Ray's email apropos A. maculatum/maculata and had to add that I don'i describe 34 forms of maculatum; quite the opposite, I discarded that many (more, infact) superfluous taxa!

I was, indeed referring to Arum maculatUM. I have not seen the book by Peter, only have the 3 pages in Deni Brown's book. Could you please post the full name of the book and the author along with information for purchasing the book you are referring to here? +More Thank you, Gene Gene Bush Munchkin Nursery Southern Indiana Zone 6a genebush@munchkinnursery.com AR>Gene & Jan, AR>Peter Boyce doesn't list an Arum maculata in his book, nor have I heard AR>of it.

You'll love it. Informative and the illustrations are fantastic. MJ Hatfield

From: Tony Avent <tony at plantdel.com> on 1997.12.01 at 22:43:59(1678) Peter Boyce or other Arumettes: We are growing a number of arums, and are thoroughly confused with Arum maculatum. None of the plants that we are growing as A. maculatum are solid green or spotted black. They are all patterned with silver. Could I assume that all of these are actually A. italicum or hybrids between the two. Also, I got two specimens labeled A. maculatum 'Variegated' from Pontzyfield Herb Nursery in Scottland. They appear to be classic heavily silver patterened A. italicum except that they never went dormant this past summer when all others died down. They still look great now...what is happening?

It does seem like a lot of Arum maculatum in the US is either mis-identified or not spotted. I had a lot of questions about this, too. The true Arum maculatum is quite distinct (spotted or not) from A italicum (marked or not). My spotted plants self sow with both spotted and unspotted seedlings apppearing. The plate of A. maculatum in Peter Boyce's wonderful book "The Genus Arum" is a bit wierd in that it makes the black spots almost look like 'sores'. In my plants there is a far simpler black (Dark brown) mark more like that done with a permanent marker. The spots are scattered around the leaf at random. I have some seedlings named as hybrids that are washed with a silvery pattern, but unlike that of A. italicum pictum. Still too young to compare, but it seems these 2 must hybridize pretty readily and the hybrids have some vigor! A maculatum in flower is distinct! Hope it was of some help. jim W. James W.

From: "Peter Boyce" <P.Boyce at lion.rbgkew.org.uk> on 1997.12.03 at 14:17:59(1694) Dear Tony The really crucial question is when do your plants break growth. Arum italicum emerges in late summer/early fall and remains in leaf until latel June/July. Occasionally the new leaves will emerge while a few tattered leaves of the previous season remain. Arum maculatum emerges in winter to late winter (it's JUST beginning to show in southern England) and is generally gone completely by late May. I've NEVER seen a truve A. maculatum with silver veining; always either plain green or variously spotted. Your plants are probably rither A. italicum ssp. italicum (which is HORRIBLY variable) or hybrids between this and A. maculatum.
