I'm trying to grow hippeastrums in a few areas of my yard that are not ideal. The non-ideal spots are too wet, and get too much direct sun. But I've been having some success with companion plantings, so I thought I'd share.
I have intermixed hippeastrums with Curcuma alismatifolia (siam tulips). They have a long bloom season, from late June through August or Sept, thrive in full sun, and need a lot of water. This is my second year of my experiement, and it is going well. The foliage is about the same size as hippeastrum foliage, and provides some shade to the hippeastrum leaves without shading them out. Its high water needs in the peak of summer helps to suck extra moisture away from the hippeastrums at the peak of the summer wet season when they are most prone to rot. It is a clumper like hippeastrums are, so intermixing clumps works well. It is also winter dormant, and is still dormant during the hippeastrum's bloom time, so it doesn't obscure them. And it is beautiful! Check it out:
