Being that the farm is dry, I'm looking at succulents and other flowering or colorful plants that can survive. The ice plant is a prime candidate. I've seen thick beds of this plant growing at the Costco parking lot where it gets zero attention, other than getting weedwacked back. It roots easily from cuttings, so I've just planted a few dozen segments.
Bromeliads are a family that can grow right in the rocks. No soil required though a little is preferred.
They come in a variety f colors, sizes, and shapes. So I'm adding a few here and there as I find interesting ones.
Some prefer shade, some sun. So there are varieties that are suited for just about any spot on the seed farm. It's wonderful having a plant the even I can't kill !!!
Some succulents might not be colorful but they have interesting foliage or growth habits. As a plus most don't require fertile soil. Perfect for this piece of land. Next time I head to town I intend to pick up an assortment of baby cactus. The trouble will be that I won't know which varieties they are so I won't know how big they will grow. It will be a surprise! So I will give it my best guess in choosing where to place them on the farm.
The plumaria grows like a tree and produces very colorful flowers. Whites. Yellows. Pinks. Reds. Bicolored. I've planted six small trees and I'm hoping that they're all different colors. I think that they are, it was my intention. Time will tell if they indeed are. This yellow one is the first to bloom.
