Irma no I didn't but it looks like hoovb did! I googled gasteria and that's it! How on earth did you know this plant? Thank you!

Maria, wait until the picture has fully loaded before clicking off the page. It takes awhile sometimes.

'Or whatever they have renamed it' is going to be my go-to answer for all the plants in both the Asclepiadaceae and the Liliaceae.

Thanks floral_uk. Colloquially called the healing garden as it is more than just trees per its official name. https://goo.gl/maps/1F3H1iaszAvyuf2s5 That is the location. I've nabbed quite a few exotic seeds from there that I could not find anywhere else. Quite a nifty selection of plants. Although you may have nailed it w/ Crithmum maritimum, those leaves and seeds look identical. Thank you!
