Dear Diane, Although it is much colder and hotter here than there, I do recall a really nice use of these ceramic drain tiles. A friend had a large-ish collection of sedum in similar pipes. Many of these tend to wander in the ground, but in pipes they crawl over the edges and could easily be trimmed to stay inside without mixing with other species. Of course Sedum are much hardier and can tolerate our extremes of heat and cold. I am sure the pipes freeze through each winter, but the extra strong ceramic seem to last very well without cracking. I think that growing bulbs here in these pipes would be impossible since the soil inside is much more likely to freeze in winter. And they do look really nice if artfully arranged. Have fun.
