Subject: Re: [Aroid-l] Temperature requirements for Helicodiceros (Susan B)
Iīve been silent for about a year as a result of some legal issues locall y.
However, the Helicodiceros question spurred me to break silence!
I used to live in the English countryside where winter temperatures often
fell below zero Centigrade, though not too much colder. My helicodiceros
plants (I had perhaps 30) survived these winters outdoors,below ground
(obviously!) at a depth of between 6 and 12 inches. Once mid-Spring arri ved
(mid to late April), out they came, flowering annually once of mature
age.Once mid-summer arrived (August at latest), the heat dried off the
plants and they became dormant again.
So I would say that Helicodiceros is more hardy than is generally stated
(but it not reliably hardyso probably canīt take -5C or less for lo ng
periods) while it is also not a heat lover, preferring dormancy once
temperatures reach about 25C for a prolonged period.
Of course, this was my experience for my plants in the South of England so
itīs only a guide, not a rule!
