I see, Is it really that hardy?
If, by 'hardy', you mean cold-tolerant - I have no clue as I've never heard anything about it's ability to survive temperate winters.
If you're referring to it's ability to spread to adjacent pots and become very difficult to eradicate, yes, it has a
well-deserved reputation.
I don't need any more 'issues'. My current list includes:
- D. regia that came with aphids that have survived the 1st round of treatment (separate isolation tank until pests are eliminated)
- 2 pots of a nice, small, vigorous U. reniformis that are infected w/ U. subulata that only produces cleistogamous flowers (several inches separation from other plants, daily monitoring for cleistogamous flowers until leaf or root cuttings are established)
- several utric pots that have an ugly filamentous algae that covers the media surface with a nasty 'web' (several inches separation from other plants until leaf or root cuttings are established)(or until alternate methods provide complete eradication).
Some people don't mind these issues (obviously - as they were all received in trades) but for me ....
