I purchased what is said to be a P. vulgaris it doesn't look like the photos I found online when I did a google search. It's leaves are soft like in the photo below now but in winter they are thicker and stouter and reminding me of a sword blade made of celery stalk! I got one in winter and killed it (I'm not proud) so I'm hoping someone can tell me what to do with it-and what it is!
The above photo is from the website of the shop which sold the plant. Mine looks just like it. The largest specimen they had was about 10" across.
Thanks for any thoughts!
