I have been growing these for years, but now that that you ask this question I am not able to tell you for sure when they actually do grow. They come from the KwaZulu-Natal south coast and the Eastern Cape, which means they get rain also in winter. Which again means that they are probably rather opportunistic. Mine get summer rain, no rain in winter but I do water them quite regularly. Right now they look better than they did all summer.
They flower from mid-winter to mid-summer (July to February). I do have one right now which is in bud, opening any moment. I had been neglecting this planter until recently and it didn't get as much water as it should have. Now I am not sure if it is early or late.... but it sure seems to be happy.

It looks like you are in about the same temperature range as us here in Joburg. In which season do you get your rain? I would not even try to 'reset' it or make it stick to a certain dormancy. Let it do what it wants. They are not fussy.

Hope this helps.

Thank you, Maddy.

With global warming our rain can be quite erratic but 'my' area gets rain throughout the year with January-February being on the dry side.

This April has also been quite dry but there's a southerly coming through(???)

I'm around Lat 41S compared with your 26S, but we have the wind and some good microclimates. More 'maritime', and that helps to moderate the hots and colds.

The Zephyranthes have been flowering, and Habranthus, so I guess it's just a matter of time before Cyrtanthus pushes through.

Hi,

I have some C. mackenii hybrids (other parent is C. brachyscyphus) that shrug off our year round rain. It is generally always rainy or humid here.

C. mackenii is reputed to be one of the most tolerant and easily grown species in this genus. As long as you donÂt get too cold for too long, it should do well for you under many conditions, as long as it has adequate drainage.

Cordially,

C.J.
