Recently we had dinner at Maguro-ya sushi restaurant and were inspired by their decorative avocado sprouts. Their plants are entirely in water, not having been placed in dirt. Living in Hawaii, it is easy to get avocados year round. Sprouting them is a lot easier than in Tennessee as well, especially with the trick of leaving them in the shower where it's nice and humid.
This recently sprouted plant has been growing at an amazing pace! I had to remove it from the bathroom as it had reached the ceiling! It is now in the living room, and it may well reach the ceiling in there pretty soon as well. Since taking the picture, it's leaves have increased in size and the small chute at the bottom has grown and has a couple leaves of its own now. It is fun to watch the plant grow every day -- and because it is in water, we can watch the roots grow as well.
