I am very interested for xeriscaping plants especially trees suitable for beekeeping ( nectar or pollen ).My target is to use a number of plants flowering at different seasons of the year.I am already use Parcinsonia acuelata, Leucaena leucocephala, Ceratonia siliqua, Rosmarinus officinalis, Melia adzetarach, Eucalyptus torguata, Eucalyptus leucoxylon, Acacia farmesiana.Any other suggestions?
I'm willing to bet that the Palo Verde tree that has tons of yellow flowers would help. VERY drought tolerant and fast grower from seed. Left all my seedlings in CA when we moved but they were about three feet tall the first year.
When I sowed them, I nicked them a little and soaked them over night, then used bottom heat and a dome. I grow several of my stuff under lights in the winter.. the humidity makes them germinate really fast. I think the seed coat on this is pretty hard, you can also just use a nail emory board and sand off some of the seedcoat so that moisture can get in. Once they germinate they will grow pretty fast and need transplanting or they out grow their pots... I don't know if they have deep tap roots though, because I put mine out into the ground after a couple of months.
