I've just became a happy owner of Arum hygrophilum and am wondering about
its requirements. Should it be treated as other arums, with moist
winter/spring and dry summer/fall? Any advice will be appreciated...

Hey what do you guys know about Arum hygrophilum? Is it fairly common, not common at all, prolific, or not at all. Any help would be wonderful. Thanks people!-Danny Wilson Get a FREE online computer virus scan from McAfee when you click here.

Hi Danny and Everyone!
I grow a lot of Arum hygrophilum here in the Central Valley of
California. It is not a very common plant, and can be quite difficult to get
hold of initially, but once you have it, it's vigorous and easy to grow. It
also grows quite large (for an Arum) and makes many offset babies. The
leaves emerge in the late fall (around October here) and the first blooms
appear in January. A healthy plant will have leaf tips reaching nearly 3
feet high, which is rather high for this genus, and will make several
blooms. Of all the Arums I grow, this one makes the most blooms, and for the
longest period of time. A plant that starts blooming in January will still
be making blooms months later, and each bloom lasts a long time.
Unfortunately, Arum hygrophilum does have a few drawbacks. One, it is
particularly frost-sensitive. Unlike Arum italicum or A. dioscoridis, which
can both take a heavy frost and shrug it off, hygrophilum tends to lose
leaves and blooms in frosts. Second, it likes a lot of water (hence the
name) and is not as drought-hardy as other Arums. Lastly (and this may be
heresy to true Arum-ophiles) the bloom is just not that interesting. Unlike
other species with showy spathes and rich odors, the bloom of hygrophilum is
a simple green tube with the lightest purple tracing on the margin of the
spathe. There is no odor at all, and overall the effect is of many, small,
colorless, tubular blooms lurking hidden under all the foliage. Rather dull
in the grand scheme of things.
I would suggest growing A. dioscoridis, A. palaestinum, A, pictum, A.
creticum or any number of other species before hygrophilum. They are much
more intriguing to look at. But if anyone wants some hygrophilum, I will
have many spare offsets this summer when they go dormant. E-mail me in June
and I can send you some.

Dear CJ, Danny et al;
Been meaning to reply and here's my 2 cents.
Contrary to my expectations a couple tubers from CJ (thanks
again) last year have come though winter. They came up early, got
beat up by freezes and now are resprouting new foliage. Too early to
give precise details, but I look forward to their success. Made it
through lows around -2 F.
We had some record drought last summer and they surely did
not get nearly the water they would have preferred. I doubt it will
reach the dimensions cj mentions in his much milder climate, too. I
don't expect to see bloom , if any this year, for another month or
Ask again in mid-summer when they go dormant.
Best Jim W.

The ecology and pollination of Arum hygrophilum has been studied by Jacob
Koach in Israel. Apparently it's not a strongly smelling species and not
thermogenic. It has a long flowering cyle (9-10 days) and it's pollinated
by midges (Psychodidae) but interestingly only by males and not females as
All the best,
