There are nine known populations, but three of these only have a few plants. The largest populations have over a 10,000 stems. These are primarily restricted to limestone pavement areas and other types of sites associated with calcareous bedrock. This type of habitat is very limiting. Some of these sites face battles with various invasive species. There are a few historical sites and the possibility that this plant has been overlooked. More survey work is needed at the sites with small populations reported, as well as at sites where habitat conditions seem suitable.

There are eight populations which have been seen in recent years. No clear trends are available for these populations but at least five of the populations are very large and extensive. The other three vary from very small (one or two plants) to medium sized. These small populations are probably declining or perhaps other parts of these populations were overlooked during survey work. Therefore, short term trends are unknown but may indicate at least a small decline.

There are at least 7 populations which have not been seen in recent years. Dedicated surveys to relocate these populations have not been conducted and it is unknown if these populations are still extant. Three populations that have been seen in recent years are very small to medium sized. Two of these have only one or two plants present. Therefore, either parts of these populations were overlooked during survey work or these populations are probably declining. Overall, long term trends are not clear but may indicate at least a small decline.
